@RDPetruska : yes I confirm I definitely use admin rights to change network settings. I just highlight the fact that without admin rights (read only view of the network settings) VM0 doesn't appear. So if it doesn't appear without admin right maybe the VMs cannot see VM0 either? Just trying any guess at this point
@carlton :
- Here are my host ethernet adapter settings (private network behind a VPN) :
IPv4 Address. . . . . . . . . . . : 10.154.1.146
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 10.154.1.1
- Yes I confirm network access in the VMs was OK with Ubuntu 20.04.4 LTS before Ubuntu upgrade to 22.04.1 LTS. Under Ubuntu 20.04.4 LTS network in the VMs actually disappeared randomly once in a while but going from NAT to bridged or bridged to NAT did the trick and it finally got going : network appeared back in the VM and it was ok... Since 2 VMs have migrated to 22.04.1 LTS this trick doesn't work anymore and after hours of troubleshooting I couldn't fix it for weeks now 
- 2 VMs using 22.04.1 LTS definitively lost network while 2 VMs still using Ubuntu 20.04.4 LTS still work : if network disappear I just cycle from NAT to bridged or bridged to NAT and network reappears;
- With the Linux VM powered down, within the Virtual Machine Settings for the VM set the Network Adapter to NAT, power up the VM and login to Linux : DONE
- ifconfig -a : doesn't exist in the Ubuntu system.
- ip link show from faulty 22.04.1 LTS

Please note in order to try to solve this I upgraded to Workstation Technology Preview 22H2 Pro (e.x.p build-20200310)
Screen capture below : 20.04.4 LTS show network connected on top right but on 22.04.1 the network doesn't appear on top right even if the network card appears connect at the bottom right in VMWARE config
Thanks for your time !
