Hi folks,
we do have a phenomenon that is not easy to get a hold onto. We are
running Debian Sarge stable domUs and NetBSD domUs on Debian Sarge
stable dom0. Xen is 2.07, compiled from the sources (with only slight
modifications for using more of iptables).
Our domUs experience extreme slow downs in network connectivitiy once or
twice a day. That means: ping times go up to 1.200 ms (to hosts on the
same subnet), ping times to hosts on the internet even much higher. In
most cases there is no packet loss, but even that can occur.
The domUs do not experience that all at the same time and not all at the
same rate (occurences/day). There seems to be no coincidence with
hardware issues or load (the physical machine is using 4-9 % cpu on the
average with just one peak a day; the occurences are not related to this
peak).
So the question is:
1. Is the packet loss problem still an issue with Xen 2.0.7?
2. Is there a (maybe related) issue with prolongued ping times?
3. If 1 or 2 is yes, can the developpers please comment on the state of
bug fixing here?
Thanks for any input.
Dirk
