Hey, I seem to be hitting this on a revision well after the fix: r283896.
The guest traps with:
...
kernel trap 9 with interrupts disabled
panic @ time 0.000, thread 0xffffffff813c2f20: Fatal trap 9: general protection
fault while in kernel mode
...
Registers:
rax: 0000000000811889 rbx: ffffffff814077b8 rcx: 00000000000001a0 rdx:
0000000000000000
^^^
MSR_MISC_ENABLE or
IA32_MISC_ENABLE
Are we missing some emulation? It looks like ECX is the MSR register, and
we're trying to write EDX:EAX (per [0]):
00000000 00811889
Anything I can do to help fix this? Would you prefer a new bug? Thanks.
