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):
processor : 1
vendor_id : GenuineIntel
cpu family : 6
model : 15
model name : Intel(R) Xeon(R) CPU 3050 @ 2.13GHz
For the Intel server, the guest is using the e1000 NIC or virtio or
other? I have a few DL320G5s with this processor; I have not hit this
problem running rhel3 and rhel4 guests using e1000/scsi devices.
As I mentioned, it was using virtio net.
Guests running with e1000 (and virtio_blk) don't have this problem.
