Booting Solaris 10 or 11 for Sparc in qemu-system-sparc64

I'm trying to boot Solaris 10 or Solaris 11 for SPARC using qemu-system-sparc64 but keep running into problems early on. I'm using the DVD images sol-10-u11-ga-sparc-dvd.iso and sol-11_2-text-sparc.iso available from SUN's^WOracle's web site. **Attempting Solaris 10:** $ qemu-system-sparc64 -m 1024 -cdrom /tank/images/sol-10-u11-ga-sparc-dvd.iso -boot d -nographic OpenBIOS for Sparc64 Configuration device id QEMU version 1 machine id 0 kernel cmdline CPUs: 1 x SUNW,UltraSPARC-IIi UUID: 00000000-0000-0000-0000-000000000000 Welcome to OpenBIOS v1.1 built on Mar 12 2015 08:09 Type 'help' for detailed information Trying cdrom:f...

EXIT 0 > I have tried using the -cpu help option to find a supported CPU, but no matter what string I provide, it is not understood. Has anyone gotten original Solaris 10 or 11 to boot with sparc64 under QEMU? What else should I try? PS: It is not an option to buy SPARC hardware or emulate 32bit SPARC and ancient Solaris 9 or older or use Solaris x86.
