Hi all,

I try using a VM with stubdom-dm instead qemu-dm, and "live migration" don't work.

This command "xm migrate --live w2k3-ent.15 IP_Dom0_Destiny" works, in the Dom0 destiny, created a paused VM (with memory but not a vcpus), but in the end of process, not started appropriate and destroyed VM in both Dom0 Xen. Look "xl list" below:

This description in "xl list", Dom0:

Name                                        ID   Mem VCPUs    State    Time(s)
w2k3-ent.15                                 29  4099     4        r--    545.1
w2k3-ent.15-dm                              30    32     1        r--    482.4

In Dom0_Destiny, during "xm migrate...":

Name                                        ID   Mem VCPUs    State    Time(s)
w2k3-ent.15                                  8  4099     1        -p-      0.0

I using xen 4.0.1 and a kernel

Anybody help?

Sorry for my English terrible.
