VMM QEMU - Startet nach Update nicht mehr

Hallo Zusammen,

nach dem letzten update bekomme ich beim Start von Win10 im VMM folgende Fehlermeldung:

Fehler beim Starten der Domain: Nicht unterstützte Konfiguration: Emulator '/usr/bin/qemu-system-x86_64' does not support machine type 'pc-q35-5.0'

Traceback (most recent call last):

libvirt.libvirtError: Nicht unterstützte Konfiguration: Emulator '/usr/bin/qemu-system-x86_64' does not support machine type 'pc-q35-5.0'

Kann mir jemand sagen, wie ich das wieder zum Laufen bringe?

I have used virtmanager just a few minutes ago and I cannot recognize your issue.

Ich habe Virtmanager erst vor ein paar Minuten verwendet und kann Ihr Problem nicht erkennen.

I am thinking - perhaps you are missing some packages - try installing the meta package qemu-full - it could be the simulated EFI loader that is missing.

Ich denke – vielleicht fehlen Ihnen einige Pakete – versuchen Sie, das Metapaket „qemu-full“ zu installieren – es könnte der simulierte EFI-Loader sein, der fehlt.

Wenn ich das installiere löscht das nicht meine Win10 installation?

4

Why do you think that?

Warum denkst du das?

5

Nicht ganz unberechtigte Frage, da qemu macht standartmäßig die VMs unter root und nicht unter home.
Aber du wirst dazuinstallieren, nicht wegloschen, also nicht.
Ich habe qemu-desktop Metapaket und es recht. Ich teste mein win10 wenn ich zuhause bin. Du hast Glück, in paar Tage wird mein win10 gelöscht.

6

Das hat das Problem leider nicht gelöst.

I am at home and my win10 runs. One thing to note, the error says pc-q35-5.0 and in my xml i see pc-q35-10.0.
Here is the xml of my win10:

Yesterday 2026-06-04T22:00:00Z - in a different context - I installed a virtual Windows Server 2019. Today 2026-06-05T22:00:00Z I tested creating a Windows 10. When looking at the configuration xml file I see

Gestern 2026-06-04T22:00:00Z habe ich – in einem anderen Kontext – einen virtuellen Windows Server 2019 installiert. Heute 2026-06-05T22:00:00Z habe ich die Erstellung eines Windows 10 getestet. Wenn ich mir die XML-Konfigurationsdatei ansehe, sehe ich

Beispiel XML win2k19 EFI 
  <os firmware="efi">
    <type arch="x86_64" machine="pc-q35-11.0">hvm</type>
    <firmware>
      <feature enabled="no" name="enrolled-keys"/>
      <feature enabled="yes" name="secure-boot"/>
    </firmware>
    <loader readonly="yes" secure="yes" type="pflash" format="raw">/usr/share/edk2/x64/OVMF_CODE.secboot.4m.fd</loader>
    <nvram template="/usr/share/edk2/x64/OVMF_VARS.4m.fd" templateFormat="raw" format="raw">/var/lib/libvirt/qemu/nvram/win2k19_VARS.fd</nvram>
  </os>
Beispiel XML win10 EFI 
  <os firmware="efi">
    <type arch="x86_64" machine="pc-q35-11.0">hvm</type>
    <firmware>
      <feature enabled="no" name="enrolled-keys"/>

    <boot dev="hd"/>
  </os>
Beispiel XML win10 BIOS 
  <os>
    <type arch="x86_64" machine="pc-q35-11.0">hvm</type>
    <boot dev="hd"/>
  </os>

By default the xml is readonly in the GUI.
You can however edit the file and change the machine type either console or change the settings for the virtual machine manager GUI

Standardmäßig ist das XML in der GUI schreibgeschützt.
Sie können die Datei jedoch bearbeiten und den Maschinentyp entweder in der Konsole oder in den Einstellungen für die GUI des virtuellen Maschinenmanagers ändern

QEMU does not support machine type 'pc-q35-4.2'
