[Bug 571408] Re: libvirt-bin on latest lucid: heavy packet loss

2010-05-21 Thread Philipp A. Baer 
I'm still not quite sure what the exact reason for this behaviour is.
After testing several kernels -- 2.6.26 (Lenny), 2.6.31 (self built),
2.6.32 (Lucid, Squeeze, and self built) --, distributions -- Lenny,
Squeeze, Karmic, Lucid --, and two NICs -- RT, Intel -- I can't make
head of tail of it; always the same behaviour.

It really seems somehow related to the hardware without any indication
of one specific cause. I installed Lenny, Xen, and libvirt-bin earlier
today. So far, there seems to be no packet loss any more -- on a system
that actually idles all the time. I'll do some testing next week.

Thank you so far, I'll keep you in the loop.

[Bug 571408] Re: libvirt-bin on latest lucid: heavy packet loss

2010-05-19 Thread Philipp A. Baer 
Same strange bug here (Lucid, 2.6.32-22 | 2.6.32.13, libvirt-bin 0.7.5,
lxc | Xen, amd64, Intel i7) but unfortunately the trick doesn't work for
me, i.e. disabling and enabling ip forwarding. As soon as ip forwarding
is enabled, packets are dropped again arbitrarily.

Absolutely no supportive traces in syslog, dmesg, etc. tcpdump on icmp
packets only revealed that there no icmp packets are received in case of
packet loss... I'll try to downgrade to Karmic or switch over to Debian.
