Hi,
I'm having problems trying to get
I think it is an unsync tsc problem.
First, make sure you pin all of the process threads. There is thread
per
vcpu + io thread +more non relevant.
You can do it by adding the taskset before the cmdline.
Second, you said that you use smp guest. So windows also sees unsync
tsc.
So, either
Can anyone provide any pointers as to what might cause virtio networking
to be slow (~55Mb/s)? Here's what I've tried so far:
Guests tried:
Windows Server 2003 x32 SP2 UP guest w/ Windows guest drivers ver 3
Windows Server 2003 x64 SP2 SMP guest w/ Windows guest drivers ver 3
On the host:

Ok, I tried pinning the kvm process to two cores (0,2) on a single
socket, but that didn't seem to make any difference for my virtio
network performance. I also tried pinning the process
I'm having a problem with virtio networking. I mentioned this in a
previous thread, but I'm starting a new one since Dor solved the problem
I reported in the original thread. This appears to be a new problem.
Iperf shows throughput of ~120 Mb/s between a Windows Server 2003 x64
guest and the br0

Actually, worded badly.
A UP guest on an SMP host with unsync'ed TSCs would show this too
obviously. As would changes in the TSC speed. The first I guess we
can avoid by pinning

What driver version are you using? Version 2 is obsolete
Hi, I'm having problems with STOP errors (0x00d1) under
KVM-79/2.6.18 whenever I try to use the virtio drivers. This post
(http://marc.info/?l=kvmm=121089259211638w=2) describes the issue
exactly, except that I'm using a Win2k3 x64 guest with the x64
paravirtual drivers instead of 32-bit
Sorry for the repost.. I forgot the subject line!
