Trying the above options results in us being unable to start the guest on the
AMD host in order to test migration. It complains that guest cpu is not
compatible with host CPU.

The only method that works is by creating our own profile and adding it to
cpu-model definition on both the AMD and Intel hosts:

[cpudef]
   name = "cpu64-rhel6-dsio"
   level = "4"
   vendor = "AuthenticAMD"
   family = "6"
   model = "13"
   stepping = "3"
   feature_edx = "sse2 sse fxsr mmx clflush pse36 cmov mca pge mtrr apic cx8
mce pae msr tsc pse de fpu"
   feature_ecx = "cx16"
   extfeature_edx = "lm fxsr mmx nx cmov pge syscall apic cx8 mce pae msr tsc
pse de fpu"
   extfeature_ecx = "lahf_lm"
   xlevel = "0x8000000A"
   model_id = "QEMU Virtual CPU version (cpu64-rhel6)"

We can then migrate the VM but we still encounter the same issue.
