Should be (mostly) fixed by -unstable cset 15055 (in staging
tree now).

The "mostly" is since the usb state restore (or maybe save)
doesn't seem to work, and hence mouse may not be usable
after restore.

Will look into this.

cheers,

S.

Save/restore is ok against staging tree's changeset 15020: d2ef85c6bf84,
but is NOT ok against changeset 15021: 00618037d37d (Update to qemu
0.90).



I use IA32pae HV; both SMP Windows 2K3 and FC5 can't be saved properly.

After "xm save dom_id 1.save" returns, Qemu window disappears, but "xm
vcpu-list" still shows the domain has not been killed.

If I "xm dest" the dom manually by force, and run "xm restore 1.save",
for Windows 2k3, a white Qemu window always pops up - maybe the domain
is still running normally thought the VGA is not OK, but I'm not sure.



Can somebody please look into the issue?



Thanks

-- Dexuan
