Re: [Xen-users] eth go into disabled state

Hi,

 

I got the following error messages of Domain0 /var/log/messages.

 

It happen when I reboot a DomU guest.  I observered that it happened on Fully virtualized guest(like Windows 2003, windows 2008).  During this moment, I can ping the guest OS but the Domain0 network interface is down.  After around 5-10 minutes, I can access the server again.

 

Just serve from Internet, other people also have this problem

How did you determine that? Ifconfig?
