Bug#449346: kvm: network sometimes just stops

2009-10-31 Thread Brad Barnett


Package: kvm
Version: 72+dfsg-5~lenny2
Severity: important

I have precisely the same issue, but using VDE2 as well.

The following worked:

vdekvm -net nic,model=i82559er -net vde,sock=/var/run/vde2/mytap.ctl

The following NIC models failed:

ne2k_pci, pcnet, rtl8139

That is, after brief bursts of network activity, they stopped until an
ifdown/up was issued.

Scratch that.  This:

vdekvm -net nic,model=i82559er -net vde,sock=/var/run/vde2/mytap.ctl

resulted in an instant segfault of KVM, when trying to write any data to
an NFS share.

 Could you try to reproduce the problem with the current version in
 unstable (52)?
 

Lacked time to do it properly, so I skipped the ne2k_pci under kvm-48
test, but now ne2k_pci under kvm-52 shows an appearance of correct
operation, with the caveat that the console sees frequent NETDEV
WATCHDOG: eth0 transmit timeout message under network stress (none were
appearing during the -48 days). 

I can attempt to do more specific tests if you wish; for the time being
this VM will stay as is (ne2k_pci, KVM-52) until it breaks (or not).

Bug#449346: kvm: network sometimes just stops

2007-11-05 Thread Cyrille Chépélov
Package: kvm
Version: 46+dfsg-0.1
Severity: important

since running the current versions of kvm + kernel, my guest machine drops
the network after a while (not much in the way of a correlation with
anything that I can see so far, except perhaps heavy network activity). So
far I'm a bit lost with what I might do to help narrow down the problem.

It *seems* that the guest netdev watchdog triggers sometimes, but it's for
now unclear. Can't bring up much more info before about 12 hours from now.

Regards,
