Xen users - Jun 2006 - Bridge not setup when domU starts - must manually start

Hello All,

I''m a fairly new Xen user.  I have one server that is currently running
the following:

dom0
----
RHEL 4.3
xen-3.0.2.2-86.1_rhel4.1-i386
xen-kernel-2.6.16-xen3_86.1_rhel4.1-i686
/etc/tls.disabled

domU
----
CentOS 4.3
/etc.tls.disabled

domU config file:
-----------------
kernel = "/boot/vmlinuz-2.6-xen"
ramdisk = "/boot/initrd-2.6-xen.img"
memory = 512
vif = [ '''' ]
disk = [
''phy:vg00/mothership,sda1,w'',''phy:vg00/swap1,sda2,w''
]
root = "/dev/sda1 ro"
extra = "vga=791"
on_poweroff = ''destroy''
on_reboot   = ''restart''
on_crash    = ''restart''

dom0 and domU boot okay, except for a problem with ttyS0 (mentioned in
another thread).  Anyway, the network bridge is never setup when the
server is rebooted.  I have to shutdown domU, and then run

./network-bridge stop
./network-bridge start

in the /etc/xen/scripts directory.  When I do this, the bridge gets
setup:

bridge name     bridge id               STP enabled     interfaces
xenbr0          8000.feffffffffff       no              peth0
                                                        vif0.0
                                                        vif2.0

/var/log/xend-debug.log has this when the bridge fails to start:

Error: either "local" is duplicate, or "secondary" is a
garbage.
ifdown <device name>
Error: either "dev" is duplicate, or "eth0" is a garbage.
ERROR: Not a Xen-ELF image: ''__xen_guest'' section not found.
ERROR: Error constructing guest OS
ERROR: Not a Xen-ELF image: ''__xen_guest'' section not found.
ERROR: Error constructing guest OS
ERROR: Not a Xen-ELF image: ''__xen_guest'' section not found.
ERROR: Error constructing guest OS

Umm...what?  Looks like there''s something wrong in the xen guest.  If
this is true, why then would a manual init of the network-bridge script
start up the bridge?

BTW, I haven''t changed xend-config.sxp, leaving it to default settings.

Any tips appreciated.

Thanks,

Ranbir
