#22 Importing a xen config file without vif information crashes

[Anonymous]

Wehn you import a xen config without vif information and uuid, the import is working, but you may not edit the settings or view the virtual server.

When updating the information by hand it will work, but I think it could be nice either to just ignore the missing values, so the user may edit them through the interface and fix the missing information or the import should complain about them. The best thing would be to make a notice about it and auto generate the missing information.
