Dear all, it seems like the solution would be to swich to another driver and to use qemu? In such a case,is it necessary to replace KVM with Xen or anything else?
Could you please recommend me standard way of creating virtual machines in CentOS? I was following CentOS 6 documentation and KVM with Qemu was still included.
Seems like I have to use Xen,but I abandoned Xen due to the reason it was necessary to install kernel 3.10 but suprisingly support for Intel VX virtualization dissappeared in 3.10 (vmx flag) only some hypervisor was present,but I need to run WindowsXP.Is there any way to get back this feature back to 3.10?
I am a newbie in virtualization.

We should not be depending on qom-list existing unless the feature being
used only exists in a QEMU which has qom-list. In general we expect to
be able to work with any historical QEMU, so if we've regressed in that
regard we must fix it.
