Installation Issues on Xen

Hi,

I´m having some problems with the installation of the UTM 9.0. I´m trying to install a VM using the "asg-9.003-16.1.iso" on xen.
Let me say it clear: not Citrix XenServer, just the opensource-xen that is e.g. included in opensuse.

Installations on vmware, oracle vm and even xenserver were successful, but all of these VMs were HVM-VMs (full-virtualized).

What I need in my environment is a paravirtualized install of UTM 9.0. The python Installer of the ISO just freezes at 33%..

Are there any experiences concerning UTM and paravirtualized VMs?

Any hints are appreciated!

Kind regards
Andreas
