I have a windows Server 2008 instance as a guest on KVM. When I tried to run it via virtual machine manager, the process got frozen after few seconds and trying to resume the process lead to this error from virt-manager:——
Error unpausing domain: internal error unable to execute QEMU command ‘cont’: Resetting the Virtual Machine is required
I tried to Reboot it without any success. Any help will be highly appreciated.
KVM: entry failed, hardware error 0x80000021
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.
Congratulations, you’ve run into a kernel bug.
While Ubuntu is shipping a fixed kernel for 12.10, the fix has never been backported to 12.04 LTS. (And while reading the bug on launchpad, I could not figure out how to mark Precise as affected…)
