The simplicity of Netplan has me stumped again.

Attempting to configure a single NIC with multiple subnets to be used with kvm/qemu VM hosting.

OS: Ubuntu 22.04.1 LTS 
Switch: TP-Link TL-SG108E

I have (1) bridge without a VLAN I can access the bridge IP and the IP of the VM associated with that bridge

I am attempting to setup (2) VLANs & for VMs &

I am using 802.1Q VLAN on the TL-SG108E

ID  NAME     Mem   Tag   UnTag
1   Default        1-8   1-8
11  vm1      1,3    1     3
12  vm2      1,3    1     3

Followed various Netplan examples without success.

Tempted to add a second NIC with two ports and move on but hesitate to do so as this task should be simple to accomplish.

  • Ubuntu 22 is a version number for Ubuntu Core 22 is that what you are using? If so say Core if not please edit with the actual version info.
