Which is fair but I have moved 3 bios Debian 12 without issue. I have tried 2 different Debian 12 with UEFI and both have failed with the same error.
I use open-vm-tools on them. I'll try removing it but cannot start the vm for a while because something locks the vmdk on the esxi side after doing the xo migration and I have to either reboot the host or wait a while.
I'll try building a new uefi debian 12 vm and see if it happens from a clean build.
