Re: [Qemu-discuss] qemu -cpu host

[akhilesh rawat]

thanks , but if you see the guest which was run as

qemu -cpu host

has auto generated model as SandyBridge in KVM process. 

 usr/libexec/qemu-kvm -name compute-0 -S -machine pc-i440fx-rhel7.0.0,accel=kvm,usb=off -cpu SandyBridge,+vme,+ds,+acpi,+ss,+ht,+tm,+pbe,+dtes64,+monitor,+ds_cpl,+vmx,+smx,+est,+tm2,+xtpr,+pdcm,+pcid,+dca,+osxsave,+arat,+xsaveopt,+pdpe1gb -m 61440

So now  running  "--cpu SandyBridge" will make any difference

Hmmm. your guest CPU is a different model form the host one.

Would you please:

- try forcing "SandyBridge" cpu (that'd be your Intel Xeon E312xx)
instead of host and
- check the "Recognized CPUID flags" from the output of
"qemu-system-x86_64 -cpu help" ?
