Hi,

I'm seeing similar problems on _one_ of my DomU, installed with Gentoo Linux. Xen is 3.0.2 with Kernel 2.6.16.

The problem is, that reproducing these hangs isn't possible, because I couldn't find the cause yet. All I can see is, that drop-counts on the virtual interfaces monitored with xentop are rising and none of the packets is transmitted to DomU. In my case that's a really bad bugger because my DomU is configured to use nfsroot. :-(

Greetings,

Tom

Hello,

I just installed Xen 3.0.2. It was installed on a CentOS 4.3 box.
when i'm working inside the child, sometimes network traffic freezes for about 5 seconds, then it comes live again. While this
happens inside the child, the host is ok.

I searched for this kind of behaviour, and found this post:

(almost an year old, but it's the exact same problem)

I didn't play with it at all, everything is pretty much default.

Any thoughts on this?
