Xen users - Feb 2009 - Most of You Have Probably Seen This 100 Times, But...

Attempting to install a fully virtualized instance of Windows 2003 fails
on CentOS 5.2 x86_64 with xen-3.0.3-64.el5.
 
After issuing the command...
 
    # virt-install --hvm -s 70 -f /vm/ts05/ts05.dsk -n ts05 --cdrom
/download/Win2003x64/disk1.iso --vnc -r 1024
 
The script just hangs at...
 
    Creating domain...
 
In another terminal window, I can see that vnc-viewer has been started
and is waiting for the VM to startup...
 
    31801 pts/0    S+     0:00 /usr/bin/virt-viewer --connect xen --wait
6

So I gather that the VM is not starting. 
 
SELinux is disabled. Any ideas?

I''d start with verifying that /vm/ts05/ts05.dsk and
/download/Win2003x64/disk1.iso actually exists. Next, verify that
udevd is istill running.

Other than that, the most common problem is probably X display
problem. Are you running it on a remote host or local X display?

Fajar, thanks for your suggestions. 

The files do exist.

[root@vmhost01 ~]# ls /vm/ts05/ts05.dsk
/vm/ts05/ts05.dsk
[root@vmhost01 ~]# ls /download/Win2003x64/disc1.iso
/download/Win2003x64/disc1.iso
[root@vmhost01 ~]#

Actually, ts05.dsk did not exist before issuing the virt-install command. It was
created by the -s flag.

udevd is running

[root@vmhost01 ~]# ps ax|grep udevd|grep -v grep
  793 ?        S<s    0:00 /sbin/udevd -d

I have a hunch that you''re right about it being an X display problem,
but I don''t know what the problem could be. I''m running it on
a local X display, not on a remote machine.

Do you have any other thoughts?

--Eric

My new theory is that the VNC server is not starting because Xen networking is
not properly configured. My only clue is that the following lines appear in
/var/log/messages when I try to create a Xen domain:

Mar  1 07:04:31 vmhost01 kernel: device tap0 entered promiscuous mode
Mar  1 07:04:31 vmhost01 kernel: xenbr0: port 3(tap0) entering disabled state
Mar  1 07:04:31 vmhost01 kernel: device tap0 left promiscuous mode
Mar  1 07:04:31 vmhost01 kernel: xenbr0: port 3(tap0) entering disabled state
Mar  1 07:04:32 vmhost01 kernel: device vif15.0 entered promiscuous mode
Mar  1 07:04:32 vmhost01 kernel: ADDRCONF(NETDEV_UP): vif15.0: link is not ready

And now I''ve discovered that SDL works okay, just not VNC. For some
reason, then VNC server won''t start when I run the xm create command
(and the config file has VNC enabled.)

Yup, networking is messed up, but I''m not yet sure what to do about it.
I can ping stuff on the network from the server and I can ping the server from
other stuff, but the server cannot ping itself either on 127.0.0.1 or on its own
IP address.

Oh my God, I can hardly believe it was that easy. I did an ''ifup
lo'' and
now everything works, including creating VMs through VNC. It never
occurred to me that the lo interface would be down at system bootup.
Thanks for being another pair of eyes.
