I’m on 25.10.2.1 - Goldeye and I am trying to spin up a new Linux virtual machine. I currently have three VM’s and I’m trying to spin up a new VM, but they all fail with kernel panics. I setup the configs, identical to the previous three machines, start the installation, connect via VNC, select install and they all fail as soon as the install starts with a kernel panic.
