libvirt users - May 2013 - hardware error 0x80000021 on Ubuntu 12.10, need advice

Hi,
On a DELL r610 (Intel Xeon L5520) and a Windows guest I have an
hardware error. The bug is well known[1][2] and seems fixed with the
package 3.5.0-16-generic. But I use 3.5.0-30-generic.  Do I need to
upgrade to 13.10? Or just the kernel ? Or modify the options of the
kvm module?


Thanks.

If you're running a guest on an Intel machine without unrestricted mode
support, the failure can be most likely due to the guest entering an invalid
state for Intel VT. For example, the guest maybe running in big real mode
which is not supported on less recent Intel processors.
