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

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

Hi Sadique You helped me last time to run more domUs. Now I am remembering you again . I have installed 4 virtual Pcs in Xen. And I set up the network interface and trying to ping , it does not ping. But all the VPs can ping to the host PC.
