Hi, I'm developper on the proxmox distribution. We are using kvm git, and one of our user can't boot guest win7x64 with -cpu host. (but it's working with linux guest).
It's working fine with -cpu host,level=9 but not with -cpu host,level=10 or level=11. We also try with new Westermere cpudefs in target-x86_64.conf (see redhat patches from february 2012) [cpudef] name = "Westmere" level = "11" vendor = "GenuineIntel" family = "6" model = "44" stepping = "1" feature_edx = "sse2 sse fxsr mmx clflush pse36 pat cmov mca pge mtrr sep apic cx8 mce pae msr tsc pse de fpu" feature_ecx = "aes popcnt sse4.2 sse4.1 cx16 ssse3 sse3" extfeature_edx = "i64 syscall xd" extfeature_ecx = "lahf_lm" xlevel = "0x8000000A" model_id = "Westmere E56xx/L56xx/X56xx (Nehalem-C)" That also doesn't without change level < 10. User also report that "-cpu host" was working fine with qemu 0.15. I see that other intel cpudefs in target-x86_64.conf have level=2, maybe does it need to be the same for westmere ? Best Regards, Alexandre Derumier
