[Xen-users] Xen MIgration problem

["saptarshi naha" <naha80@xxxxxxxxx>]

Hey,

I am trying to migrate Xen VM from 1 physical m/c to another. I have
instll GNBD and done the following.

VM1 to be exported:
nbd_serv -n
service gfs stop
gnbd_export -c -d  /dev/sda1 -e global_diskVM1
gnbd_export -l

Domain 0 of other machine:
depmod -a
modprobe gfs
modprobe gnbd
modprobe lock_dlm
service gfs start
gnbd_import -i  <ip adress of VM1> -n
cd /dev/gnbd

I see the global_diskVM1 in /dev/gnbd/ of Domain 0 of the other machine.

When I try and migrate (live and pause)it it gives I/O ad inode errors
after migration. THe same error is seen without GNBD, so the problem
is n my GNBD setup.

Has anyone done such GNBD simple setup between 2 machines with no SAN.
Please tell me what am I doing wrong.


Thanks in advance,
Naha
