guest domain couldn't be started

Hi,

I install a guest Fedora inside the host Fedora. When I use the

service xend status

to check the status of xend. It shows xend is running.

However when I use

xm create xen1

to start the guest domain xen1, it failed. The corresponding file xen1 is
in /etc/xen/xen1. The error msg is as follows:

[root@phillis xen]# xm create xen1
Using config file "./xen1".
Going to boot Fedora Core (2.6.19-1.2911.6.5.fc6xen)
  kernel: /vmlinuz-2.6.19-1.2911.6.5.fc6xen
  initrd: /initrd-2.6.19-1.2911.6.5.fc6xen.img
Error: Device 0 (vif) could not be connected. Could not find bridge device
xenbr1

I found the following line in file /etc/xen/xen1,
vif = [ 'mac=00:16:3e:5c:5c:31, bridge=xenbr1', ]

Why device 0 couldn't be connected? I don't know the usage of the bridge
device, xenbr1.

Anybody has similar problem ? Or know how to slove this problem? THanks.

Best
Angel

when you do an ifconfig do you see a xenbr1 or a xenbr0?

Hi there
I have installed Xen virtual machine in Red Hat Enterprise 5 named
virtpc1. Now can you tell me how can I get more copy of the virtpc1
named virtpc2, virtpc3 etc ?

What I have done so far ,

I copied the virtpc1 as virtpc2 and virtpc3 in /etc/xen , changed the
hostname and file name in config respective in /etc/xen also I copied
the disk file in /opt/virtpc1 as virtpc2 and virtpc3. 

When I type
# xm create virtpc1 , it creates domain virtpc1 fine and running fine.
But when I type xm create virtpc2 it fails but if I type xm list and I
can see two more domains created by the named virtpc1 virtpc1 , same
name twice , it supposed to be virtpc1 and virtpc2. 

Any solution please ?

Regards
selim

uuid should be uniq for each guest. Use uuidgen  and replace the uuid= 
parameter on the second and third guest.
