Auf meinem Rechner mit OS 15.5 mit aktuellen Patches,
Kernel 5.14.21-150500.55.44-default und
VMware Workstation 17.5.0 build-22583795
erscheinen nach dem Booten generell folgende Fehlermeldungen bezüglich der vmnet-Interfaces:

[    5.855204] vmnet1: Current addr:  00 50 56 c0 00 01 00 00 00 ...
[    5.855209] vmnet1: Expected addr: 00 00 00 00 00 00 00 00 00 ...
[    5.855211] ------------[ cut here ]------------
[    5.855211] netdevice: vmnet1: Incorrect netdev->dev_addr
[    5.855220] WARNING: CPU: 3 PID: 1408 at ../net \
               /core/dev_addr_lists.c:513 dev_addr_check+0xbb/0x140

Diese Meldungen tauchen bei mir nicht auf.

Wenn die gleiche Fehlermeldungen auf dem Rechner mit dem Avahi-Problem auftauchen, würde ich mal testweise die VMware-Services deaktivieren:

sytemctl disable vmware-USBArbitrator.service vmware.service

Danach den Rechner neu Booten und prüfen, ob sich bei Avahi etwas ändert.

Hat nichts verändert!

Was mir aber aufgefallen ist, ist dass der avahi Service wegen der Problemsuche gerade eigentlich abgeschaltet ist (disabled). Trotzdem läuft das Teil nach einem Boot. Stoppe ich den Service per Hand, kommt noch ein Hinweis auf avahi-daemon.socket.
