[Xen-users] XEN live migration: cannot console or ssh to the migrated guest VM (domU)
I am now testing XEN live migration on two physical hosts with XEN 4.0.1
pvops Ubuntu 10.10 (2.6.35-22). Host A also acts as a NFS server, and Host B
acts as a NFS client.
When I migrate a guest domain from B to A. The ssh connection experiences a
downtime of about 1 minute (the terminal does not react to the keyboard
input till about 1 minute later). However, the "sudo xm console" does
not
work unless a reboot is triggered.
When I migrate the guest domain from A to back B, the situation is even
worse -- neither ssh connection nor console works.
In both migration cases, you can notice that the guest domain is there by
using "sudo xm list".
Could anyone shed some light on the potential problems I am facing? I have
been working on this for quite some time, but have no idea what goes wrong. The
following is the log file copied from host B, when the guest domain is
migrated from A back to B.

Re: [Xen-users] Re: XEN live migration: cannot console or ssh to the migrated guest VM (domU)
Yes. Follow Simon''s advice, which is copied as follows: I would suggest you try with something like arping and see if you get any different results. I can think of one thing that would make the VM "disappear" from the network for a while during/after migration apart from the downtime while the migration actually happens : Every switch (bridge) on the network will have learned the port to which the node is attached and cached it in it''s MAC <-> Port table. When you move a machine, these switches will continue to forward unicast packets via the port it has in it''s tables UNTIL it has reason to update the table entry. Thus packets may get sent to the wrong place for a while - and so the migrated machine just doesn''t get any traffic. Most switches will update the table as soon as it sees a packet from the device arrive on a different port. Depending on what''s going on, that may take a second, or minutes. Arping uses ARP request packets to probe a device rather than unicast ICP-Ping packets. These being broadcast will be flooded to the entire network and so will reach the device even though it''s now on a different port. When it replies, the intermediate switches will update their MAC table accordingly. Also, I''ve found some switches can be slow to update. We''ve some HP 1800-24G switches at work, and they seem to have a 5 minute timeout before they''ll update the MAC table. I guess it''s probably configurable via CLI - but I haven''t looked. -- Simon Hobson Visit http://www.magpiesnestpublishing.co.uk/ for books by acclaimed author Gladys Hobson.

Re: [Xen-users] Re: XEN live migration: cannot console or ssh to the migrated guest VM (domU)
The problem is unrelated to networking. I cannot even "xm console" to the VM migrated, from the final dom0. I suspect the problem is with hvc drivers.

Re: [Xen-users] Re: XEN live migration: cannot console or ssh to the migrated guest VM (domU)
This might not apply to other distros than Redhat 6, but I guess its a similar bug explained in this thread. see this https://bugzilla.redhat.com/show_bug.cgi?id=663755 Paras.
