Problem in migrating xen domains
Im facing problems while migrating domU's to different machines. Both
servers have commom filesystems for domU's mounted from NFS. xfrd runs on
both servers. Memory is available in the destination server. When I do a
live migration from server1 to server2 , the server1 just hangs . I have to
powercycle it.

Please let me know any spl config steps to be done and help me in resolving
this issue.

This is the xfrd.log in destination server.

Re: Re: Problem in migrating xen domains [ In reply to ]
I also encountered the same problem on FC4.
Probably a cause is this.

Get source rpm, change 1 line, and do make tools.
