Description Marian Krcmarik 2011-07-26 18:28:36 UTC

Description of problem:
Spice client is terminated when doing multiple migration of one spice client session. Just do migration from source host to target host and back. When doing the second migration client is closed with message (first migration is successful):
1311704317 INFO [5681:5681] main: Spice client terminated (exitcode = 0)
Migration was done through libvirt and RHEVM3 on RHEL6 host. Once I do migration with the same spice client version on RHEVM2.2 with RHEL5 hosts I am able to do multiple migration (that's why filing bug for spice-server).
After reconnecting with spice client everything is fine => migration itself of guest is successful.

Version-Release number of selected component (if applicable):
qemu-kvm-0.12.1.2-2.171
libvirt-0.9.3-7
spice-server-0.8.1-2
spice-client-0.8.0-2

How reproducible:
always

Steps to Reproduce:
1. Connect to a guest using RHEVM3.0 User portal or virsh
2. Keep spice client session.
3. Do migration to another host.
4. Keep spice client session.
5. Do migration back to original host.
  
Actual results:
1311704317 INFO [5681:5681] main: Spice client terminated (exitcode = 0)

Expected results:
No visible changes for user.

Investigation done together with Marian suggests that before the second migration libvirt does not send migrate_info to spice (via qemu-kvm monitor command), so upon migration the server disconnects the client.

Even though I hit it constantly on different setups, Now I am not able to reproduce, but almost all components got updated. I will do some more tests. In case I am not able to reproduce I will close this bug.

Ah, nice additional info, #727969 is a bit similar, but this bug seemed to be different. Given your last comment, maybe it was related to this one.

I will retest migration with latest components since there were several changes and sort out all those bugs.

Comment 5 Marian Krcmarik 2011-08-08 14:06:01 UTC

I am not able to reproduce on updated components. Closing, will open If I hit that again.
