Hello,
I'm running kvm-79 on SLES 10, which has a 2.6.16.

I never have these hangs on 2.6.27.
The hangs seem to be related to qcow2 images on local and on NFS disks.
When I uses iscsi as disk the hangs do not occur.

Hi,
This is a new spin of the series to disable vmx on kdump and on
emergency_restart. Now we avoid doing the function pointer stuff by
moving 4 small KVM functions to a header, as inline functions. The code
looks much simpler now, but we have to be more careful because some
additional code will

On emergency_restart, we may need to use an NMI to disable virtualization
on all CPUs. We do that using nmi_shootdown_cpus() if VMX is enabled.
Finding a proper point to hook the nmi_shootdown_cpus() call isn't
trivial, as the non-emergency machine_restart() (that doesn't need the
NMI tricks)
Create cpu_svm_disable() function.

We need to disable virtualization extensions on all CPUs before booting
the kdump kernel, otherwise the kdump kernel booting will fail, and
rebooting after the kdump kernel did its task may also fail.
We do it using cpu_emergency_vmxoff() and cpu_emergency_svm_disable(),
that should always work,
Unfortunately we can't use exactly the same code from vmx
hardware_disable(), because the KVM function uses the
__kvm_handle_fault_on_reboot() tricks.
