My homelab environment is primarily git repo->puppet apply->centos7 hardware running kvm or guests. Simple tooling but it works. I'm doing a lot more terraform at work these days and have been thinking about refreshing my homelab with an ansible/terraform pattern but I've been looking at my OS base for the KVM hosts and wondering if there is a better way. So, the question...... Is anyone aware of a unix OS pattern that's PXE booting, immutable, container friendly and usable as a basic KVM host? Something like CoreOS/Flatcar but for KVM guests instead of just containers. Ideally with config data from cloud-init and something like vault. Thanks!

I am trying to understand if I can install win 10 VM on oVirt host/node and then use that PC as my win 10 desktop? running the win 10 VM? Thanks.

I used the REST-API to collect the statistics of a Virtual Disk using oVirt REST API and I got the following response, https://1.1.1.1/ovirt-engine/api/disks/b14da816-37e3-46d7-8617-2e42e52db996/statistics/ Response to this ***API***, { "statistic": [{ "kind": "gauge", "type": "decimal", "unit": "bytes_per_second", "values": { "value": [{ "datum": 0 }] }, "disk": { "href": "/ovirt-engine/api/disks/b14da816-37e3-46d7-8617-2e42e52db996", "id": "b14da816-37e3-46d7-8617-2e42e52db996" }, "name": "data.current.read", "description": "Read data rate", "href": "/ovirt-engine/api/disks/b14da816-37e3-46d7-8617-2e42e52db996/statistics/33b9212b-f9cb-3fd0-b364-248fb61e1272", "id": "33b9212b-f9cb-3fd0-b364-248fb61e1272" }, { "kind": "gauge", "type": "decimal", "unit": "bytes_per_second", "values": { "value": [{ "datum": 0 }] }, "disk": { "href": "/ovirt-engine/api/disks/b14da816-37e3-46d7-8617-2e42e52db996", "id": "b14da816-37e3-46d7-8617-2e42e52db996" }, "name": "data.current.write", "description": "Write data rate", "href": "/ovirt-engine/api/disks/b14da816-37e3-46d7-8617-2e42e52db996/statistics/2f23addd-4ebd-3d82-a449-c28778bc33eb", "id": "2f23addd-4ebd-3d82-a449-c28778bc33eb" }, { "kind": "gauge", "type": "decimal", "unit": "seconds", "values": { "value": [{ "datum": 0 }] }, "disk": { "href": "/ovirt-engine/api/disks/b14da816-37e3-46d7-8617-2e42e52db996", "id": "b14da816-37e3-46d7-8617-2e42e52db996" }, "name": "disk.read.latency", "description": "Read latency", "href": "/ovirt-engine/api/disks/b14da816-37e3-46d7-8617-2e42e52db996/statistics/3a7b3f72-d035-3bb9-b196-e86a4eb34993", "id": "3a7b3f72-d035-3bb9-b196-e86a4eb34993" }, { "kind": "gauge", "type": "decimal", "unit": "seconds", "values": { "value": [{ "datum": 0 }] }, "disk": { "href": "/ovirt-engine/api/disks/b14da816-37e3-46d7-8617-2e42e52db996", "id": "b14da816-37e3-46d7-8617-2e42e52db996" }, "name": "disk.write.latency", "description": "Write latency", "href": "/ovirt-engine/api/disks/b14da816-37e3-46d7-8617-2e42e52db996/statistics/b1e75c7b-cea4-37d2-8459-f7d68efc69a3", "id": "b1e75c7b-cea4-37d2-8459-f7d68efc69a3" }, { "kind": "gauge", "type": "decimal", "unit": "seconds", "values": { "value": [{ "datum": 0 }] }, "disk": { "href": "/ovirt-engine/api/disks/b14da816-37e3-46d7-8617-2e42e52db996", "id": "b14da816-37e3-46d7-8617-2e42e52db996" }, "name": "disk.flush.latency", "description": "Flush latency", "href": "/ovirt-engine/api/disks/b14da816-37e3-46d7-8617-2e42e52db996/statistics/9c17ad7b-9ef1-3e8d-ad0a-ff8bee3925f0", "id": "9c17ad7b-9ef1-3e8d-ad0a-ff8bee3925f0" }] } So As per my understanding, It is able to retrieve 5 statistics (***i.e***) Read and Write Bandwidth, Read, Write and Flush Latency. My question is, Is it possible to get the ***READ / WRITE IOPS*** of virtual disk / VM? Thanks, Harry

I have a group of VMs with certain tag. I would like for users (that all belong to a group) to have the UserVmManager permission for those VMs. From what I've found, Red Hat documentation isn't particularly clear on how to do this. Does anyone know if this is possible, and if so where to read about it?

I am trying to start a vm in paused mode, but running into issues. I'm able to connect to the API and start vms normally, but I cannot seem to get the params part right for staring paused. In this example, vm is the virtual machine object obtained from the api with the vm in question. from ovirtsdk.xml import params vm.start(params.Action.set_pause()) This gives me a "TypeError: unbound method set_pause() must be called with Action instance as first argument (got nothing instead)" self.vm.start(params.Action.set_pause(pause=True)) This gets me the same thing.

I am using the oVirt API, I am checking into the ovirt documentation, It has the following as payload, myvm Blank mycluster 1) What is the difference between template and cluster? I can understand that template - It is a configuration which we can set and apply for multiple vm's but What is cluster? 2) Is it necessary to use the template and cluster in using createVM rest API in ovirt? 3) Can't we create a vm without specifying the template and cluster?

I'm having a _really_ weird issue with oVirt. I download ISOs, and they'll work for about ~3 boots, and then they just start kernel panic'ing out of nowhere. The error is as follows: Kernel panic - not syncing: No init found. Try passing init= option to kernel. Removing quiet doesn't add more visible debug info. This has so far happened on around five different downloads of CentOS. I've verified the checksum of the ISO with the one provided on the CentOS website, and it's fine. Everything is hosted in an ISO domain, as an NFS share. Unfortunately, this happens with Glance templates as well, mainly CentOS. Debian Buster worked the first time, after a couple other ISOs failed, but I haven't repeatedly tried it. I'm running on the latest oVirt version (4.2.2), with the hosted engine, and this only started after updating from 4.2.0. Thanks in advance!

I cannot find any documentation pertaining to the list of searchable properties of objects (VMs, Hosts, etc) within oVirt / RHEV-M? There is no documentation on this, either in RHEV or oVirt sites (via Google). Can someone provide a list of such attributes?

I installed ovirt on a machine that was already hosting KVM virtual machines. I am now trying to migrate those VMs over to RHEV format, but I am receiving SASL authentication errors using virt-v2v. I am not being prompted for credentials upon running the command virt-v2v Windows7.xml -o rhev -os host.domain.net:/home/images --network ovirtmgmt Windows7 The error is virt-v2v: Failed to connect to qemu:///system: libvirt error code: 45, message: authentication failed: Failed to step SASL negotiation: -7 (SASL(-7): invalid parameter supplied: Unexpectedly missing a prompt result) This has been driving me crazy all night. Does anyone know anything about this?

I'm trying to use the manager to find a VM associated with a particular MAC-address. I'm using the search-bar in the WUI. The RHEV-M guide and oVirt CLI examples get me only so far. In the search bar, I try VMS: vnic.network_name = X* and I get all VMs with an interface in any of the X... networks. But I want to search on the mac address. Tried the obvious, (mac, mac-address, mac_address) but no go. For comparison, I tried "00*" which definitely should have gotten hits.

I'm trying to install ovirt on my mint laptop. Installing oVirt on a debian distribution is expirimental and there is little knowledge about troubleshooting on the web. However, I have found the source of my issue, I'm just not sure how to fix it.
