Hi together,

i am having problem with Live-Migration of hvm-guests.

My System is:

# xm info | grep xen
release                : 2.6.26-1-xen-amd64
xen_major              : 3
xen_minor              : 2
xen_extra              : -1
xen_caps               : xen-3.0-x86_64 xen-3.0-x86_32p hvm-3.0-x86_32
hvm-3.0-x86_32p hvm-3.0-x86_64 
xen_scheduler          : credit
xen_pagesize           : 4096
xen_changeset          : unavailable
xend_config_format     : 4

Live-Migration of Linux-pv-guests works fine but not with hvm.

  # xm migrate hvmguest otherxenbox --live

throws errors like

invalid device midel signature read

The log-files say
 all memory is saved
 save exit rc=0
--> seems fine, but then
 save failed ....
 could not write device model state

in the debian-xen-kernel-changelog i read that this should work....

Any Suggestions?
