    • Unable to start Xen VM since upgrade to OMV4

      Hello Community,

      i was running OMV3 with Xen-Hypervisor 4.3 (or 4.4, don't remember xD) for some months and all worked like a charm.
      But since i upgraded to OMV4 with Xen-Hypervisor 4.8 i can't boot Xen-VM's.
      I've got the following Errormessage in Virt-Manager: "Libxenlight failed to create Domain "xxxx".
      And in the logs i've got: "Unable to find partition containing kernel".

      I tried to clean install with OMV4.0.9 ISO but that changed nothing.
      Doesn't matter if i try to boot a VM per Virt-Manager (SSH) or directly on the Server.

      I'm really going to despair...also couldn't find anything in google for this issue, so i hope that you guys can help me! :thumbsup:

      ASUS Mainboard
      Intel Xeon X3440
      4GB ECC RAM
      60GB Kingston SSD
      3TB WD NAS-Storage
    • I also can not boot KVM/Qemu-VM's, same error.

      I installed now a basic Debian 9 and the Xen-Packages. Same error appears :(

      Virt-Manager errormessage:
      Installation konnte nicht fertiggestellt werden: «internal error: libxenlight failed to create new domain 'ubuntu16.04'»
