Re: [Xen-users] domU shell prompt freezes after live migration

[David Della Vecchia <ddv@xxxxxxxxxxxxxxxx>]

Are you on debian by chance? I had the exact same issue, it has to do with the kernel you are using for the domU.

Here is the bug report describing it: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=644604

I've had this occur with other kernel's i've built, not just debian provided ones. I was able to build a 2.6.39.4 and a 3.0.1 kernel last night that restored my ability to do xm save and restore without the console lock up.

Hope this helps.

I have narrowed down and further defined the problem using xm commands:

1. the problem does not have to do with migration from one node to another per se:

an xm save and subsequent xm restore done from either box, without migration, reproduces the problem. In each case a vm is produced that I can ping and login to, but which produces the frozen prompt.

I have also tried the following:

2. opened permissions on .img files under /ocfs2SAN/domains
to no avail,
therefore not a permissions problem

3. opened up sysctl buffers on both boxes
to no avail
not a sys buffers problem




Might I perhaps have a file system or cluster configuration problem?
