Xen users - May 2011 - OpenSUSE 11.4 (2.6.39-30.1), Xen 4.0.2 - Device 0 (vif) Could not be connected

All,


This is a fresh, un-f#$ked-with OpenSUSE install after adding the Tumbleweed
repository and doing a dup.  I installed the Hypervisor with Tools for which
it prompted me for Xen or QEMU and I chose Xen.  No bridge was made.

When I go to create a fully virtualised machine, it nao has the error:

Error: Device 0 (vif) could not be connected.  Could not find the bridge,
and none was specified.

The bit in the config file says:

# SuSE users note:
# On openSUSE >= 11.1 and SLES >= 11, networks should be configured using
# native platform tool - YaST.  vif-bridge and qemu-ifup can be used to
# connect vifs to the YaST-managed networks.
#(network-script network-bridge)

So... how exactly is YaST supposed to do this...? ...so I don''t have to
re-install OpenSUSE for the 5th time on the same machine?

I just did this last week.  I''m not sure what Tumbleweed is, I was
using the Xen 4.1 repo from
http://download.opensuse.org/repositories/Virtualization/openSUSE_11.4/

At least in my case, YaST2 didn''t seem to make the bridge
automatically, although I''m sure I did something stupid (I
hadn''t
touched OpenSuSE for over a year, so I was a little rusty).  So I
ended up making /etc/sysconfig/network/ifcfg-xenbr0 by hand.

That worked fine if I used xm create.  However for some reason xl
create would never add the vif to the bridge, so networking in the
domU wouldn''t work.  I''m sure I was doing something stupid,
but I just
used xm as I didn''t have time to figure it out.

I don''t remember having any of these problems w/ 11.3 & Xen 3.4.x
:).

When you say made ifcfg-xenbr0 by hand, what all did you do for that?

All,

This is a fresh, un-f#$ked-with OpenSUSE install after adding the Tumbleweed
repository and doing a dup.  I installed the Hypervisor with Tools for which it
prompted me for Xen or QEMU and I chose Xen.  No bridge was made.

When I go to create a fully virtualised machine, it nao has the error:
Error: Device 0 (vif) could not be connected.  Could not find the bridge, and
none was specified.

The bit in the config file says:
# SuSE users note:# On openSUSE >= 11.1 and SLES >= 11, networks should be
configured using# native platform tool - YaST.  vif-bridge and qemu-ifup can be
used to
# connect vifs to the YaST-managed networks.#(network-script network-bridge)
So... how exactly is YaST supposed to do this...? 

-------------

you could try uncommenting
(network-script network-bridge)

chances are, you''ll get a working network compatible with xen.

If you want to make a manual bridge,

----------------------- ifcfg-br0 ------------------
> sudo cat /etc/sysconfig/network/ifcfg-br0
BOOTPROTO=''dhcp''
BRIDGE=''yes''
BRIDGE_FORWARDDELAY=''0''
BRIDGE_PORTS=''eth0''
BRIDGE_STP=''off''
BROADCAST=''''
ETHTOOL_OPTIONS=''''
IPADDR=''''
MTU=''''
NETMASK=''''
NETWORK=''''
REMOTE_IPADDR=''''
STARTMODE=''auto''
USERCONTROL=''no''
#ETHTOOL_OPTIONS=''wol g''
---------------- snip -----------

backup/archive the ifcfg-eth0

Only one should be active at a time.

Thanks to Mark and Dustin, I have made it a bit further.  I had to
modify the xend-configure.sxp to have (network-script ''network-bridge
bridge=br0 netdev=eth0'') plus making the br0 device manually in
/etc/sysconfig/network/ifcfg-br0.

Now I have a VM (OpenSUSE 11.4, again) but I am getting

"Unable to configure the network card because the kernel device (eth0,
wlan0) is not present.  This is mostly caused by missing firmware (for
wlan devices).  See dmesg output for details."
