Hi Folks,
I am having some issues with xen hypervisor crashing because it could not find
one of the cores in my processor. This is not consistent. It happens once in
every two or three boots.
Is this is xen bug or is it something related to BIOS. If it is a xen bug, has
it been addressed and could you point me to the right patch.
Here is the xen boot message.
The highlighted entry will be booted automatically in 5
seconds.
