[Qemu-devel] [Bug 712416] Re: kvm_intel kernel module crash with via nano vmx

[khetzal]

yes this appears to be a duplication but the original bugreport has been
posted one year ago and there is no evolution. Moreover, it's not posted
on the officiel qemu / kvm bugtracker ;).

I'm waiting that my current installation complete and i test the new
kernel / kvm, but i've tested one week ago with the linux kernel kvm git
branch and the git master version of kvm, and it crashed directly.
