Hi,
Great to hear that you solved the issue. As a suggestion for next time:
Execute: service vdsmd restart on the node. You'll not loose your
running VMs and it will work afterwards.
I think I managed to pinpoint the issue, however we're still trying to
verify the patch I have implemented as a proposal for it.
I noticed that logs won't help me that much on that issue as this is
some condition where the connection between host and guest times out due
to the server being busy or something. I am not 100%ly certain about the
cause, however the solution will be to reissue connects on time outs.

It'd be nice if you could send me the logs from
/var/log/vdsm/vdsm* which are on the node where it looses the
contact. I am currently trying to find exactly the cause of such
an issue as well and it would be helpful if we could be provided
with log files. Currently I am still lacking them.
I will check them and let you know what I will be able to find.
If you wouldn't mind I would be referring to you for more
questions if some will come up during the search for the cause and
I will let you know the results asap.
thanks,
jonathan
