For migration, it is needed that yr OS disk should be visible from the both the dom0.

That means yr OS must be at SAN or NAS somewhere and should be mouned to common mount point at both the machine.

Other requirment is both machine should be identical.

I think machine hardware as well as dom0 should be identical.

If u dont have nas/san then u can do one thing ........export some dir in a dom0 as nas location and mount that location to both machine.

Hi all,


When migrating (not live) a domain from one dom-0 to another dom-0, the migration fails. On the destination dom-0, with xm list, I can see the domain that should have been migrated, but neither its files have moved from one host to another, nor can I login with xm console.


The OS of the source dom-0 is RedHat 5.0, the destination OS dom-0 is CentOS 5.0. Can this be the problem?


Both servers are in the same network. As written in previous posts I have changed few lines in /etc/xen/xend-config.sxp on the destination dom-0:


(xend-relocation-server yes)

(xend-relocation-port 8002)

(xend-relocation-hosts-allow 'ip.address.of.soruce my.domain')


The dom-X is file-backed VBD.


Since this in not live migration, there is no disk visible to both domain-0s.

In /var/log/xen/xend.log I can't find hint of what is the problem.


Thanks in advance.
