Hi all,
when i create a guest OS i am getting this error:
Error: Device 0 (vif) could not be connected. Hotplug scripts not
working.
I have looked for a possible solution without success.
The sistem is a Centos 5.2 x86_64, the xen version is 3.4, the dom0
kernel is 2.6.27.19-5 (from xensource).
The domU is a Centos 5.3 x86_64, kernel 2.6.18-128.1.6.el5xen
xend-config.sxp:
(xend-unix-server yes)
(xend-relocation-server yes)
(network-script 'network-bridge bridge=eth0') #i have specified
'bridge=eth0 for test
(vif-script 'vif-bridge bridge=eth0')
(dom0-min-mem 196)
(enable-dom0-ballooning yes)
(dom0-cpus 0)
(vncpasswd '')
the domU config file:
bootloader = '/usr/bin/pygrub'
memory = 256
name = "blade_test"
vcpus = 2
vif = [ 'bridge=eth0' ] #doesn't work vif = []
dhcp="dhcp"
disk = [ 'tap:aio:/home/xen/blade8_disk,xvda1,w!' ]
vnc = '0'
vncviewer = '0'
stdvga = '0'
on_poweroff = 'destroy'
on_reboot = 'restart'
on_crash = 'preserve'
extra = "3"
udev:
root 682 0.0 0.0 12992 1172 ? S<s 16:41 0:00
/sbin/udevd -d
brctl show:
bridge name bridge id STP enabled interfaces
eth0 8000.0022649c123a no peth0(loglevel
DEBUG)
When i create the domU i see the grub console, then i choose a kernel
and the console hangs.

If i comment the line with vif = [] in domU config file the sistem
boot correctly.
Any idea?
Thanks in advance,
Muriel

OK there is something wrong in the scripts.
If i create the vm without vif it correctly start. When the machine is
running, if i add there a card i can see and configure: it works, i can
ping the gw.
But when the vif creation timeout in the script occured the card is removed.
How can i fix it?
Muriel
