ssh destination: --VM : Oracle VM Virtual Box 4.3.20 --Linux installed on VM: Fedora 22 (IP: 10.0.2.15 ) ssh source: --Windows 7 Desktop I installed putty on Windows 7 Desktop and am trying to connect to Fedora 22 VM using putty. To make this work, I have configured "port forwarding" from Oracle VM GUI menu. for the "Host IP", I tried the "IPV4 Address" under "Wireless LAN adapter Connection" since I am on wifi at home. I also tried "IPV4 Adddress" under "Ethernet adapter VirtualBox Host-only Network". Finally I tried 127.0.0.1 for the "Host IP". None of these work. Upon all of the above attempts, I receive "Connection timed out" from my putty. Once I can make this work, my next goal is to ssh from one VM to another VM. FYI - My second VM shows the same IP address of the first VM I put in, I am guessing I need to change the IP address of the second VM manually. Please let me know if you have any advice on this as well.

Im trying to resize a disk partition in Ubuntu 22.04 in OracleVM. I already resize the disk in the VM software but in Ubuntu the disk still with the old size. I think it resize but in a new partition and I can't use that partition. When trying to change the disk size in the Ubuntu disk management this error pops out: Any solution? I need to be able to use the disk.

I am able to use the Oracle Virtual Machine Manager (OVMM) REST API successfully with the Ansible URI module with the exception that I have to pass the username and password to EACH call instead of grabbing the session cookies from the first call and using them thereafter. As I understand it the following should work, however I get a '401 Unauthorized' from the second call. I have tried a number of variations in the second call. When I debug the playbook I see the cookies (JSESSIONID and _WL_AUTHCOOKIE_JSESSIONID) are being passed as expected. To be clear, if I change the second API call to use basic_auth, username and password it works.

- name: Get OVM Manager
    local_action:
        module: uri
        url: "{{ baseuri }}/Manager"
        url_username: "{{ ovmUser }}"
        url_password: "{{ ovmPassword }}"
        validate_certs: false
        force_basic_auth: true
        method: GET
    register: login

  - name: Get info about VMs
    local_action:
      module: uri
      url: "{{ baseuri }}/Vm/id"
      validate_certs: false
      method: GET
      headers:
        Cookie: "{{ login.cookies_string }}"  # Why doesn't this work???

I have an installed Kali linux 2020.2 on my Oracle VM and by mistake I turned my computer OFF when the Oracle was saving the session ... and now when I'm trying to boot on it get stuck at "the Dragon logo" What I've tried so far: - Left it for an hour ... and it always stuck as the image above shows - I changed the Kernel I tried 5.6.0, 5.7.0, 5.8.0, 5.9.0 - And for grub I tried with splash (delete this value) and quit (change it to non-quit) **How to fix that boot problem**

I have difficulties understanding the following situation: Dom0 image:

[root@Dom0]# du -h 19.12.0.0_dbhome_1.img
980M    19.12.0.0_dbhome_1.img

is mounted on DomU:

[root@DomU]# df -h /u01/app/oracle/product/19.12.0.0/dbhome_1
Filesystem      Size  Used Avail Use% Mounted on
/dev/xvde        50G   62M   47G   1% /u01/app/oracle/product/19.12.0.0/dbhome_1

When I write data to /u01/app/oracle/product/19.12.0.0/dbhome_1 the disk usage on DomU and Dom0 increases accordingly:

[root@DomU dbhome_1]# dd if=/dev/zero of=./test.img bs=4k iflag=fullblock,count_bytes > /dev/null
[root@DomU dbhome_1]# df -h /u01/app/oracle/product/19.12.0.0/dbhome_1
Filesystem      Size  Used Avail Use% Mounted on
/dev/xvde        50G   21G   27G  44% /u01/app/oracle/product/19.12.0.0/dbhome_1

[root@Dom0]# du -h 19.12.0.0_dbhome_1.img
21G     19.12.0.0_dbhome_1.img

When I remove the data the diskusage of DomU is being reduced, but Dom0 stays the same:

[root@DomU dbhome_1]# rm test.img
[root@DomU dbhome_1]# df -h /u01/app/oracle/product/19.12.0.0/dbhome_1
Filesystem      Size  Used Avail Use% Mounted on
/dev/xvde        50G   62M   47G   1% /u01/app/oracle/product/19.12.0.0/dbhome_1

[root@Dom0]# du -h 19.12.0.0_dbhome_1.img
21G     19.12.0.0_dbhome_1.img

How does the difference come about?

I did the following procedure to create and mount the image:

[root@Dom0]# qemu-img create 19.12.0.0_dbhome_1.img.img 50G &>/dev/null
[root@Dom0]# xm block-attach domU file:19.12.0.0_dbhome_1.img /dev/xvde w >/dev/null 2>&1
[root@Dom0]# ln -s 19.12.0.0_dbhome_1.img.img /path/to/link/19.12.0.0_dbhome_1.img
[root@Dom0]# vi vm.cfg (added link to disks[] parameter)

I am running manjaro in an Oracle VirtualBox to test a virgin install of a set of softwares. I am getting an error that there is no more disk space on a particular download, however, when I set up the vm in the VirtualBox Manager, I am allocating it plenty of space (> 100GB). I have tried changing this from dynamic allocation to a fixed partition, but this did not solve the issue. When I run lsblk, this is the output:

So to me it looks like the 134gb partition needs to be mounted? I run sudo fdisk -l to see where it is:

I hope this is the right place to ask this question. I'm trying to install Oracle Linux 8.1. It works but then the reboot needed after the installation takes it back to the installation screen. It basically does not boot into the Oracle VM. I got an error when I tested the memory and it saved this: Is there a way to attach the error log? It's a long file

I am trying to install a Let's Encrypt certificate on a Oracle Linux Server 7.6. Since the server does not have a public IP, I had to validate via DNS.I followed the instructions here https://github.com/joohoi/acme-dns-certbot-joohoi and the validation worked and I got the certificate. How do I now install the certificate? I followed instructions online and moved the certificate to etc/ssl/certs and deleted the old certificate. After restarting the machine however the website does not work and I get an error site cannot be reached. I can interact with the server only via SSH.

I am running Ubuntu 16.04 LTS. I am trying to use Oracle VM to load a Kali Linux operating system and get an error that I see is quite common with a lot of other people online. The thing is that most people run Windows and the solutions end up irrelevant to my case. I will include a screenshot of the exact issue I am getting. I have tried to update, uninstall and install again. Still, the very same issue persists. Any assistance would be greatly appreciated since I do not know what else to do. Thank you in advance.

Basically what I am looking for is similar feature like RDP on Windows. I should be able to view the login screen through VNC Viewer. Even if server is restarted I should still be able to access it through VNC Viewer. Currently someone has to first obtain the console through OVM (these are all VMs), login and only then is it possible to remote through VNC Viewer. I know this question has been asked here previously [\[ref1\]][1] [\[ref2\]][2] also here but so far I have been unsuccessful in my attempts. Can anyone provide a detailed guide on how to go about achieving this? - OS: Oracle Linux 5 - VNC rpm : vnc-server-4.1.2-14.el5_6.6 Update 1 - VNC at User Level ------ Ok so I followed everything listed [here](https://superuser.com/questions/147109/automatically-start-vnc-server-on-startup) - Logged in to the server through PuTTY using root (because that's the acount I need to use for logging in through VNC). - Ran vncpasswd and set the VNC login password. - Saved the script as

/etc/init.d/vncserver

after changing the following parameters: - USER="root" - DISPLAY="1" - Did

+x /etc/init.d/vncserver

. - Did

--level 2345 vncserver on

. - Did

/root/.vnc/xstartup

and uncommented the lines:

unset SESSION_MANAGER
    exec /etc/X11/xinit/xinitrc

and changed last line from

&

to

&

(since I'm using GNOME). - Restarted the server. Now I could successfully remote to the server through VNC Viewer. This works even if server is restarted. However, **it bypasses the lock screen and does not prompt for password**. For this I had to set up a password through **System > Preferences > Remote Desktop**. **Important Note:** As @slm described below, this method provides VNC access at user level. Meaning you can create multiple users and provide them VNC access separately. Each user will have a unique desktop. This wasn't exactly what I was looking for though! Update 2 - VNC at System Level, like RDP on Windows ------ After implementing @slm's solution, I realised that this was what I actually had in mind when I asked this question. I followed exactly what he said. It's a lot simpler! Couple of things I would like to add: - I didn't need to install x11vnc. I used only the vnc rpm that was installed by default. - /etc/X11/xorg.conf file was missing. To create it I did the following: (Source) - As root run: Xorg :1 -configure. This will create the file /root/xorg.conf.new - cp /root/xorg.conf.new /etc/X11/xorg.conf I followed rest of the instructions. Restarted gdm and Voila! It worked! I was able to see the login screen through VNC Viewer, exactly like RDP on Windows. It worked even after server restart. Great!

I have a Linux virtual box and want to install Guest Additions. I've successfully mounted the iso. But now what...? How can I access the mounted cd-rom in the terminal of the virtual machine as to install Guest Additions? When I cd media then ls returns empty.

Is there a way to enable proper promiscuous mode in Oracle Virtual Server based virtual network? It seems like card is getting only some percents of total network traffic. I have tried all of the network types which are available on the Oracle Virtual Manager infrastructure. Simplest possible case: "local" virtual network of three hosts, file is being transmitted from one to second host, third host is trying to tcpdump network. File is successfully transmitted, but third host has got only one packet from the start of file transfer. I think it should be finetuned by usage of some xl commands. It can be some common problem on all of the Xen based virtualizations. What should be done to get traffic be seen to other network participants? All network interfaces were created like with OVM> create vnic name=capture_network_card network=local on vm id=${id} where 'local' is the name of the virtual network type.

I tried to create other hosts/cards but without any success in traffic capture. Further findings: If replay some PCAP files on such a network, capture card will see only some ICMP and ARP packets. It will see other packets only if replay traffic directly to the virtual host network adapter. I determine this adapters on the server through OVM and OVS consoles: [ovm]# exec 'list network'|grep local id:105e4d86c5 name:local So the **105e4d86c5** is the network id. Searching on the vmserver interfaces from this network **105e4d86c5** [root@vmserver2 ~]# ip a |grep 105e4d86c5 16: 105e4d86c5: mtu 1500 qdisc noqueue state UP 19: vif1.2: mtu 1500 qdisc mq master 105e4d86c5 state UP qlen 32 37: vif3.6: mtu 1500 qdisc mq master 105e4d86c5 state DOWN qlen 32 44: vif3.6-emu: mtu 1500 qdisc pfifo_fast master 105e4d86c5 state UNKNOWN qlen 500 if I tcpreplay traffic directly to this vif* adapters - their virtual hosts can tcpdump this packets for sure. But, if I run tcpreplay on virtual host and tcpdump on server - there will be no traffic again, tcpdump prints about packets 'dropped by kernel'. I have very little experience with Xen, but the same configuration in VMWare is working like a charm. Is there way at all to get working packet sniffing in oracle virtual network?

I am planing to move form OVM to hyper-v, in-order to do the migration, I shutdown OVM (VM is using Oracle Linux 7.2) normally, then exported the appliance from OVM Console, move it to Windows machine then convert it to vhdx file using StarWind V2V Image Converter. When I start the converted VM and try to use (Oracle Linux Server (3.10.0-327.el7.x86_64 with linux) 7.2 everything is working fine without any issue, how ever if I use (Oracle Linux Server (3.8.13-98.7.1.el7uek.x86_64 with unbreakable Enterprise Linux) I got Dracut rescue mode with the following error message (shown in the attached image) I searched from some solution regarding this issue like executing dracut -f, edit /etc/fstab manually (note the file appears fstab.empty creating a file manually did not help at all), check if I can edit /etc/default/grub but the file dose not exist either, removing the corrupted kernel using rpm -e I got the following error "kernel dose not exit" but if I try to install it using yum or rpm it failed since the kernel exist, I have tried to fix the LVM using the solution on Redhat portal , but I got the following error message "/run/lvm/lvmetad.socket: connect failed: no such file or directory" (attaching a screen shot) For further troubleshooting I opened "/run/initramfs/rdsosreport.txt " file and found it contains errors as shown in the screen show below I tried to execute the commands bellow but it filed /bin/sh no such file or directory mount --bind /proc /mnt/sysimage/proc mount --bind /dev /mnt/sysimage/dev mount --bind /sys /mnt/sysimage/sys chroot /mnt/sysimage dracut -f exit cd / sync telinit 6

We have solaris zones running in [Sparc T5](https://blogs.oracle.com/orasysat/the-sparc-t5-servers-have-landed) server Currently a solaris zone run Solaris 10 OS version. $uname -a SunOS zone01 5.10 Generic_150400-30 sun4v sparc sun4v Going further, we would like this zone to run Solaris 11 OS version, because Solaris 10 OS is going End of Support. ------------------------------------- Critical goal is: We do not want to build new solaris zones(Solaris OS 11) at any cost. We want existing zones to get upgraded to Solaris 11. Why do we use these zones? Because we have a business application running on it, which is the actual usage scenario. My understanding for upgrade of zone is, shut down all solaris zones and upgrade Sparc T5 server(not solaris zone) from solaris 10 to solaris 11. Start solaris zones after upgrade of Sparc T5 server. What is the recommended approach to upgrade an OS of an existing solaris zone? Edit: I read that: "We can simply detach a Zone from one Global Zone (OS) and attach it to another Global Zone on another machine along with the application." Can't a solaris 10 zone be migrated from version 10 global zone to version 11 global zone? And then upgrade the migrated zone...

I'm trying to automate the installation of physical servers using PxE. In this case I'm installing Oracle Virtual Servers (OVS for short, RHEL/Centos-like systems with Xen and custom linux kernel). I followed the steps outlined in the official documentation and implemented them using ansible. To summarize I took in account some important notes: - I'm using version 3.4.2 so I'm building my own boot loader for UEFI-based PXE clients. - I'm using Oracle Linux 7.3 since it provides the grub2-tools package that is required to build the GRUB2 boot loader. With ansible I configured my tftp, dhcp and http servers (for simplicity all of them in the same box) which all seem to be working as expected (tested downloading files and IP assignment and everything works). Here is how I'm building the boot loader $ grub2-mkimage -p '(tftp,)' -O x86_64-efi -d -c -o /core.efi Here is the current state of my grub2.cfg file: set timeout=60 # Load modules insmod net insmod efinet insmod tftp insmod gzio insmod part_gpt insmod efi_gop insmod efi_uga insmod video_bochs insmod video_cirrus insmod all_video insmod ext2 insmod multiboot2 insmod normal menuentry 'Install Oracle VM Server 3.4.2' --class fedora --class gnu-linux --class gnu --class os { # dhcp, tftp server in my network set net_default_server= # This is for testing echo 'Network status: ' net_ls_addr net_ls_routes echo 'Loading Xen...' multiboot2 /isolinux/xen.gz dom0_mem=max:11582M dom0_max_vcpus=20 noreboot echo 'Loading Linux Kernel...' module2 /isolinux/vmlinuz ip=dhcp vlanid= repo=http:///pxelinux/ISOs/OVS3.4.2 ks=http:///pxelinux/kickstart/ovs-3.4.2.ks ksdevice= echo 'Loading initrd...' module2 /isolinux/initrd.img } The server boots properly, the IP is being set, both the core.efi image and the grub2.cfg file are being downloaded from the tftp server and I get the "Welcome to Grub!" message but just when it should run what's configured in the grub2.cfg file this happens: //Start PXE Over IPv4 Station IP Address is X.X.X.X Server IP Address is X.X.X.X NBP filename is /boot/grub2/core.efi NBP filesize is 397824 Bytes Downloading NBP file... Succeed to download NBP file. Downloading NBP file... Succeed to download NBP file. Welcome to GRUB! Unknown command 'menuentry'. Unknown command '#'. Unknown command '#'. Unknown command 'echo'. efinet0 efinet0:local / efinet0 efinet0:default 0.0.0.0/0 gw Unknown command 'echo'. Unknown command 'echo'. Unknown command 'echo'. Unknown command '}'. And finally I'm directed to the grub prompt, where I can type all the commands in the grub2.cfg file correctly and actually boot and install my system with kickstart. So I'm guessing I'm missing something in the grub2 image creation because it's like some modules are not being imported before running the grub2.cfg file?? Only certain commands are being run, the rest are "Unknown".

I'm running a linux VM guest inside a Win10 host. I assigned 3 cpu cores to the VM (out of the 4 cores of my i7 6600K). When compiling some big software package I run make -j3 and then looked at the CPU usage in Win10 Task Manager it's pegged at > 95%. I was naively expecting something around 75 or 80%. Anyone knows what's going on? Screenshot:
