I could not start my VM in UVMM:

Die Anfrage konnte nicht bearbeitet werden.

Fehlernachricht des Servers:

Fehler beim Verwalten der Domäne "0f4d779b-5b9a-8a92-1829-a4bff8dd2c1f": Cannot get interface MTU on 'br0': No such device

Changing the interface from br0 to virbr0 helped.

Profiles are created with the default virt-network interface in UCS4, which is br0. Our virtualization servers still use eth0 as the bridge interface. The profiles should be corrected, e.g. by using the instructions from the manual: http://docs.univention.de/handbuch-3.2.html#uvmm::profile::network

We should enhance the error message and show that sdb link in that case. Or writing a diagnosis plugin.

This issue has been filed against UCS 4.2.

UCS 4.2 is out of maintenance and many UCS components have changed in later releases. Thus, this issue is now being closed.

If this issue still occurs in newer UCS versions, please use "Clone this bug" or reopen it and update the UCS version. In this case please provide detailed information on how this issue is affecting you.
