Description Thorsten Stärk 2007-12-03 17:29:09 UTC 
Description of problem:
I try to install a XEN VM. After the sparse file is created, I get the error
message:
Unable to complete install 'libvirt.libvirtError virDomainCreateLinux() failed
POST operation failed: (xend.err 'Device 0 (vif) could not be connected. Hotplug
scripts not working.')
Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/create.py", line 681, in do_install
    dom = guest.start_install(False, meter = meter)
  File "/usr/lib/python2.4/site-packages/virtinst/Guest.py", line 649, in
start_install
    return self._do_install(consolecb, meter)
  File "/usr/lib/python2.4/site-packages/virtinst/Guest.py", line 666, in
_do_install
    self.domain = self.conn.createLinux(install_xml, 0)
  File "/usr/lib64/python2.4/site-packages/libvirt.py", line 503, in createLinux
    if ret is None:raise libvirtError('virDomainCreateLinux() failed', conn=self)
libvirtError: virDomainCreateLinux() failed POST operation failed: (xend.err
'Device 0 (vif) could not be connected. Hotplug scripts not working.')
'
I have no idea what happens here and I would like to ask for better error messages.

Version-Release number of selected component (if applicable):
default from RHEL 5.1


How reproducible:
100%

Steps to Reproduce:
1. install RHEL 5.1
2. boot XEN kernel
3. use virt-manager to install RHEL 5.1 on a new domU
  
Actual results:
I get the error msg shown above.

Expected results:
It works.

Additional info:
xend is running
Comment 1 Daniel Berrangé 2008-07-11 14:05:47 UTC 
So we can diagnose what was wrong, please provide

 -  the xen config file from /etc/xen/GUEST-NAME
 -  the /var/log/xen/xend.log file
 -  output of 'ifconfig -a', and 'brctl show'
Comment 2 R P Herrold 2008-09-03 21:05:35 UTC 
I too can reproduce this at will with a fresh 32 bit domU install running (or trying to) on a 64 bit dom0

[root@centos-5 xen]# cat 32bitcentos5-runtime
name = "32bitcentos5"
memory = "256"
disk = [ 'tap:aio:/opt/xen/32bitcentos5.img,xvda,w', ]
vif = [ 'bridge=xenbr0', ]
bootloader="/usr/bin/pygrub"
vcpus=1
on_reboot = 'restart'
on_crash = 'restart'

## for a console, one may need to add to /etc/inittab:
##      co:2345:respawn:/sbin/agetty xvc0 9600 vt100-nav
## and also add xvc0 to /etc/securetty
## per http://wiki.centos.org/TipsAndTricks/Xen

#       VNC stuff
vfb = [ "type=vnc,vnclisten=0.0.0.0,vncdisplay=2,vncpasswd=123456" ]
vnc=1
vncpasswd='123456'
