Virtual console unavailable after DomU migration
Last modified: 2007-11-30 17:07:41 EST
Virtual console no longer works after migrating a domain from one box to
another. DomU is still fully functional in every other respect and accessible
via xm, ssh, etc.
Not enough info to diagnose the problem - please provide at the very least
- RPM versions for 'xen', 'libvirt' and 'virt-manager' in your Dom0
- The kernel version used in the guest DomU
- The '/var/log/xend.log' & xend-debug.log from both source & destination
machine involved in the migration
- The /etc/xen/<name> config file for the guest VM being migrated
Are you referring to the graphical console, or the text (serial) console of the VM ?

Logs attached. These are fresh logs after a RHEL5 migrate from source to dest
and back again. Problem also occurs with Fedora domUs running any of the above
Ok, these package versions show you're using a version of the kernel/xen with
the old style paravirt framebuffer protocol. This original implemnetation did
not support migration. Prior to RHEL-5 GA we merged a new style framebuffer
implementation which does support migration.
The fix is in the following versions (or later):
They will be included in the RHEL-5 GA release.
