Re: [Xen-users] domU shell prompt freezes after live migration
Thanks, David,
This could be very useful. We are running Debian Squeeze for the
dom0 (kernel: 2.6.32-5-xen-amd64), but Ubuntu (lucid) for the domUs.

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?
