univention-virtual-machine-manageer-node-kvm error

univention-virtual-machine-manager-daemon installs ok 
univention-novnc installs ok

upon installing univention-virtual-machine-manager-node-kvm
an error occurs (see attached screenshot) and server is not reachable via network anymore
by setting ucr uvmm/kvm/bridge/autostart=manual eth0 and rebooting the server is accessible again
Comment 7 Philipp Hahn univentionstaff 2014-08-29 08:59:48 CEST
Running a KVM server with DHCP-client enabled is insane: For KVM we copied the Xen behavior to rename the physical interface "ethX" to "pethX", which allows us to create a bridge with that name "eth0" instead. As "dhclient" is still using the old name "eth0", it is now confused as the interface was renamed to "peth0" behind its back, leading to the network failure.
Long-term the rename-script should be removed.
For now I strongly recommend to reboot the server after installing KVM (or Xen) because of the network-bridge-dance.

(In reply to Philipp Hahn from comment #7)
> Long-term the rename-script should be removed.

That's Bug #33694.
Comment 9 Philipp Hahn univentionstaff 2014-08-29 14:10:43 CEST
FYI: post-installing u-v-m-n-kvm worked for me even with DHCP-client.
RFC: What was the exact setup you were testing?
Comment 10 Drees Dormann univentionstaff 2014-09-01 15:28:03 CEST
it is working now.
i was using xen2 for testing, no other modules installed.
