As a test I'm scp the CentOS DVD iso from one machine to the domain from within the DomU itself.
I'm getting "stalled" errors every so often which leads me to believe I'm still getting network hangups.
I'll try wget from a website to see if that's another test as it could be the machine.
I ran a ping test from last night to this morning and did see that it would hang every so often. There's no time/pattern that it stops running sometimes it's good for a minute sometimes it's good for 20s. Sporadic hangups are occurring.

Yes I I assigned static MAC address in each DomU

vif=['mac=00:16:3e:57:03:1b, bridge=xenbr2'] Hmmm this might be a problem. I changed the 2nd one to read 00:17 restarting domains
If it's this simple i'm going to shoot the machine. Wed, Jan 21, 2009 at 10:19 AM, Fajar A. Nugraha <fajar@xxxxxxxxx> wrote:

instead of sporadically.
Just a hunch, did you assign static MACs to each domU?
Are the domUs always active (e.g something like a web server that's
always accessed day and night) or does it have long periods of idle
where no packet comes in/out? If it's mostly idle, try doing this :
- ssh to domU from outside host
- ping the router
- leave the ping/ssh window open for a day or two, and see if that
domU still have problems.
