[Qemu-devel] qemu hard freezing host

[David Klasinc]

Greetings,

If I turn on the hardware virtualization in BIOS and then run qemu the
host machine will freeze giving no details on what might cause the
freeze. I did try the -no-kvm & -no-kvm-irqchip qemu will work and there
will be no freeze.

As you can see from the info below, CPU is Intel's E6600 and motherboard
is SuperMicro something with ICH7.

This problem is always reproducable and it happens each time I try
running qemu with kvm. KVM modules are loaded, so this shouldn't be an
issue.

Oh, another fun thing is that I am building a cluster and I have four
computers like this, all exactly the same and the problem exists on all
four of them.


If anyone can shed any light on this problem I'd appreciate all the
help.


Regards,
David
