[Xen-users] Problem starting Xen Guest!
 
| 
 Dear All,  
  
I am a newbie to Xen and I am trying to set up a Xen VM with more than one guest running on a single machine. As a setup, I have Xen 3.1.0 installed with fc7 core and trying to run debian-4.0 guest image on one of the guest environment. After starting the xm guest domain, the console gets hanged up at  DHCP request command, the log is  as below: 
 
[root@steelbug xen]# xm console debian.4-0
