Xen networking without bridging

Hello, supposedly you can do secondary interfaces (virtual interfaces?) for your virtual machines (domU’s) and not loose your eth0 to the bridge. Is there documentaion on Xen in OpenSUSE without bridging?

Thanks

Hmmm…
you can configure bridge without loosing interface - just do everithing by default. I have 2 servers with this configuration - working fine.

Hi all,

I try to create an internal subnet in virt-manager under host details/virtual network but I received error when I press finish.

It says:

Traceback (most recent call last):
File “/usr/share/virt-manager/virtManager/createnet.py”, line 301, in finish
self.conn.create_network(xml)
File “/usr/share/virt-manager/virtManager/connection.py”, line 628, in create_network
net = self.vmm.networkDefineXML(xml)
File “/usr/lib64/python2.6/site-packages/libvirt.py”, line 1293, in networkDefineXML
if ret is None:raise libvirtError(‘virNetworkDefineXML() failed’, conn=self)
libvirtError: this function is not supported by the hypervisor: virNetworkDefineXML

I didn’t find anything in google.

My sytem: Opensuse 11.2 default install with the latest update
I installed hypervisor thru KDE Yast.

My ifconfig says:

Any help would be appreciated.

If you need more debugging info/log just let me know and I will copy/paste here.

You go into Yast and install hypervisor and boot the xen config and you can still access the host os with ssh or vnc etc???

Ok I tried this again. 11.2 in a machine with eth0 and eth1. Go into yast and install hypervisor and tools. Installs around 7 or 8 packages. Only one question is asked, for vm’s to function you need a bridge, configure default bridge now? I answer yes and my NX remote desktop freezes because the bridge has commandeered both eth0 and eth1 and stolen there ip configuration rendering eth0 and eth1 unconfigured. I have to use the remote ip based kvm (lucky for me we have one) and unbind the ****ed br interfaces from the eth’s and reconfigure the eth’s back the way they were before I can reconnect across the network to the host os.

I’m also looking for a solution to this exact problem.
I can confirm exactly what you described there.

I have never tried Xen before, so I wasn’t sure how to proceed.

Installing and running it was a day at the beach, no probs there.

I didn’t have a chance to properly see how it performs because of the
network problem, but I think it didn’t give me anything over other
virtualization methods, so instead of digging into the network I gave it
up, for a while at least that is.

I can try again later if this gets resolved.
Does anybody have an opinion like Xen versus VMware?

So no one is doing this?
