Hi,
While executing runqemu on qemux86-64 image with kvm option, I am getting CPUID kvm_asyncpf error. Have anyone faced this issue? Is there any fix for this issue?
I am attaching my cpuinfo along with this mail.
Following is the console output.
[root@openbmc qemux86-64]# runqemu qemux86-64 kvm

Hi,
Update: I could get past the issue by setting -cpu host,enforce in qemu command.
Runqemu was setting cpu as core2duo.
