[Xen-devel] Problem booting from DVD

[Sven Oehme <oehmes@xxxxxxxxxx>]

Hi , 

i created several HVM Domains , without
Problems, but as soon as i try to boot from a DVD iso or from a DVD the
domain bootup hangs.
in xm log i get the following error
:

(XEN) (GUEST: 1) Unknown opcode at 4004:672D=0x4676D
(XEN) (GUEST: 1) Halt called from %eip 0xD392A

i tested several xen-unstable since changeset 9996 , even 10053 (today) has the same Problem ..
