[Qemu-discuss] Blue screen error on windows server 2008 and 2012

[John Y.]

I have two hosts.

Host A:
Intel(R) Xeon(R) CPU E5-2680 v2 @ 2.80GHz
2CPUS
10 cores and 2 thread per cpu.

Host B:
Intel(R) Xeon(R) CPU  L5520  @ 2.27GHz
2CPUS
4 cores and 2 thread per cpu.

In host B, I run a windows 2012 vm , double click a exe file inside vm and
I got a blue screen error.

error code : KMODE_EXCEPTION_NOT_HANDLED

I use the same image to create a vm in host A, I can open the exe file
inside vm and everything is ok.

I had try:
1. use "<cpu mode="host-model"/>" instead of "<cpu
mode="host-passthrough"/> "
2. use qemu2.5 instead of /usr/libexec/qemu-kvm(1.5.3)

Any idea?

Host :
Linux hostA 4.2.0-1.el7.elrepo.x86_64
