[Solved] Unable to Install UCS 4.2 in a KVM VM under Proxmox 4.4



I’m trying to setup a UCS 4.2 VM under Proxmox 4.4 (KVM). The install proceeds normally through the Base System & Additional Software phases of the install but never reaches the System Setup phase. It halts with the following error message displayed:-

I have tried many variations of disk/NIC/display emulation as well as EFI & Bios boot but always arrive at the same point.

In /var/log/messages I see:-

May 29 07:59:28 unassigned-hostname systemd[1]: univention-system-setup-boot.service start operation timed out. Terminating.
May 29 07:59:28 unassigned-hostname systemd[1]: Failed to start LSB: Univention System Setup on boot.
May 29 07:59:28 unassigned-hostname systemd[1]: Unit univention-system-setup-boot.service entered failed state.

And so looking into /var/log/univention/system-setup-boot.log shows:-

Has anyone experienced similar behaviour or can shine some light on this problem ?


I meant to add that installing UCS 4.2 on the same bare metal box as is running Proxmox works fine with the same installation ISO. So I think I can safely rule out hardware or installation media faults. Seems like some problem/incompatibility between the UCS installer & Proxmox KVM.


Hi tose,

I professionaly used a virtualized UCS cluster under Proxmox 4.4 and it works like a charm, so it’s not a Proxmox unmet dependency or environment.

I hope you’ll find a solution.



For anyone who finds themselves in the same position, use of the “text mode” installer resulted in a successful installation without the issues I encountered above using the Graphical Installer.


Just as a note: We use Proxmox together with UCS, in various combinations, from UCS3 up to UCS4.2, from PM3 up to PM5 (at time of writing PM5 is still beta), for several companies of various sizes, with and without support from Univention and/or Proxmox.
We never experienced any problem with the UCS installer, no matter textmode or graphical installer was used for installation as virtual machine in Proxmox.

So please check your UCS installation media (md5sums are ok?) or your proxmox configuration, or the configuration of the virtual machine (sufficient ram/cpu/hdd-image?)

Thanks for the response Lutz. Yes, the MD5 checksum on my install media is correct.

I also have several UCS installations both for customers & myself. My experience has been that UCS 4.1 installations upgrade fine to 4.2, but fresh 4.2 installations have been problematic for me on Proxmox 4.4 using the graphical installer.

As far as the VM options you mention, I use:-

RAM: 512 MB - 6GB RAM range automatically assigned
CPU: Default (kvm64) with 1 socket, 2 cores
HDD: (Virtio) SCSI 32GB

I use raw disk images rather than qcow2 and my host filesystem is EXT4 LVM.

Anything of concern in the above that you can see?


ok, let’s test your config, my system/config/vm for the tests:

With this settings, i was able to install UCS4.2 without(^1) problems:

^1: to be honest: i had some problems with the english keyboard layout… thats all
