Description of problem:
As subject, The latest RHEL6.5 qemu-kvm has no "-M rhel5.6.0"
RHEL6.3 and RHEL6.4 release qemu-kvm version also haven't "-M rhel5.6.0", Not sure if need to it.
Version-Release number of selected component (if applicable):
qemu-kvm: qemu-kvm-0.12.1.2-2.386.el6.x86_64 /
Steps to Reproduce:
RHEL6.5 qemu-kvm has no "-M rhel5.6.0"
/usr/libexec/qemu-kvm -M ?
Supported machines are:
pc RHEL 6.5.0 PC (alias of rhel6.5.0)
rhel6.5.0 RHEL 6.5.0 PC (default)
rhel6.4.0 RHEL 6.4.0 PC
rhel6.3.0 RHEL 6.3.0 PC
rhel6.2.0 RHEL 6.2.0 PC
rhel6.1.0 RHEL 6.1.0 PC

rhel5.5.0 RHEL 5.5.0 PC
rhel5.4.4 RHEL 5.4.4 PC
rhel5.4.0 RHEL 5.4.0 PC
The last machine type introduced in RHEL5's qemu is rhel5.6.0, as part of the fix for Bug #603026 (by Paolo).
Should the rhel5.6.0 machine type be supported in RHEL6 as well?
If I understood the fix for Bug #603026 correctly, users should be upgrading their machine types on RHEL5 to rhel5.6.0, which is an extra reason to support it in RHEL6.
I guess the reason we don't have rhel5.7.0 and above machine types in RHEL5 is because the hardware has not changed at all. Is that correct?
Even the hardware of rhel5.6.0 is the same as rhel5.5.0. Only the migration format is different.

But then does it mean users should be using the rhel5.6.0 machine type instead? In other words: should we fix this bug in RHEL-6.5?
No one is likely using the RHEL5 machine types in RHEL6, but it is simple and safe so I think it should be fixed.

OK. It's now too late for 6.5, but let's fix it in 6.6. Took the liberty and devel_ack'd it.
