[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.

 

PS: the serial log follows:
