Description of problem: When i run migration of X concurrent loaded Windows guests some of the guests are loosing theirs network connectivity after few iterations: ( see also BZ 499110 ) Guests answer to ping queries on the destination host only after few minutes. We had the same issue with 5.4 kernel before. Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info: Host CPU model: Intel(R) Xeon(R) CPU E5310 @ 1.60GHz KVM version: kvm-83-161.el5 Kerenl version: 2.6.18-191.el5 #1 SMP Mon Mar 1 15:59:02 EST 2010 x86_64 x86_64 x86_64 GNU/Linux
Oded, what's the host load? You said (off bugzilla, why not add it here?) that manual migration does work. What happens when you manually do migration with movies? What about capturing tcpdump on the destination to see tx packets?
I'm not sure that this bug is related to the Guest load: When the movie ended on guest it paused from some reason instead of continue in a loop ( probably KVM/Media player issue ). After the movie was stopped the problem still occurred. I think that the issue here is the migration frequency rather than load. If you need help with capturing tcpdump on the destination to see tx packets i can help/guide Lawrence guys how to do it.
