Could you add a (unused) e1000 interface to your virtio guests?
As this issue happens rarely for me, maybe you could help to reproduce
it as well (i.e. if network gets slow on virtio interface, give e1000
a IP address, and try if network is also slow on e1000 on the very
same guest).
Will do and report
BTW, what CPU do you have?
One dual core Opteron 2212
Note: I will upgrade to two Shanghai Quad-Cores in 2 weeks and test with
those as well.
I have this "slowness" on an Intel CPU as well, after about 10 days of
guest uptime (using virtio net):
