Re: [Xen-users] DomU hangs sporadically

[Jonathan Weismann <jweismann@xxxxxxxxx>]

Yes I I assigned static MAC address in each DomU

vif=['mac=00:16:3e:57:03:1b, bridge=xenbr1']

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.

If it's MTU problem then your domU's network should always not work,
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.
