[Xen-devel] It seems the "machine check exception handling" breaks HVM guest

Hi Jan Beulich, 
> changeset 15414: 3cf5052ba5e5  x86: machine check exception handling
With the c/s, when creating HVM guest, I can only see a white Qemu
window. :(

Can you have a look? Thanks.

Is it definitely that changeset, or is that simply the first changeset tip
you tested with to exhibit the problem?

RE: [Xen-devel] It seems the "machine check exception handling" breaks HVM guest

I’m not sure if the c/s is the cause, but the c/s 15413 seems OK, and c/s 15414
is not OK.

I can boot a HVM guest with c/s 15417  with 64bit Xen,
Linux/x86-64 as Dom0 and Linux/x86-64 as HVM DomU on AMD-V.

Can you provide more information, please? Do you use AMD-V ? Do you use a 
32bit or 64bit xen, what is your Dom0, what is your HVM guest?

This is a VMXAssist bug, so not related to AMV-V, I will send a patch to
fix it soon.
