KVM: does not work properly. Using workaround

Reprinted please indicate the source, contribute their own power for open source, thank you: http://www.openext.org/2014/06/libvirt-erro2

To learn more about KVM, you have manually installed qemu-KVM but the following occurs when creating a VM:

KVM: does not work properly. Using workaround

We initially think that KVM does not have insert, so:

# Modprobe KVM

# Modprobe KVM-intel

# Dmesg | tail

KVM: vm_exit_load_ia32_perf_global_ctrl does not work properly. Using workaround

The above information shows that it is indeed a problem with KVM, but this is not the case.

View libvirt log

# Vim/var/log/libvirt/lib1_d. Log

04:20:45. 308 + 0000: 1345: Error: virdomaindefparsexml: 12066: Unknown OS type hvm

04:30:47. 441 + 0000: 1337: Error: virqemucapsgetdefaversion version: 1748: Internal error: cannot find suitable emulator for i686

We found that libvirt did not find qemu when calling qemu.

So the solution is as follows:

Make a link under/usr/bin/

Ln-S/usr/local/qemu-KVM/bin/qemu-system-x86_64 qemu-system-x86_64

This solves the problem.
