  • Thread-topic: [Xen-users] CPU1 FATAL TRAP, Xen won't boot
Looks like it's failing one of the sanity checks. I wonder if it's
difficult to add the string that failed to the "BUG_ON()" macro... 

Line 131 in my version of the code, that is a few weeks old, checks that
the (VMCS_REVISION_ID != vmx_msr_low) [and it fails if that's TRUE...]),
and it's basicly comparing the other processors to the boot processor...


I don't think it should fail like that... :-(
