How to override VM UEFI boot in LXD 5.3 and use seabios?

Thanks,

Well I’ve certainly gone the real long way around this one, but that error message lead me to this new feature:

How to boot with BIOS instead of EFI?

I’m migrating some existing KVM virtual machines to LXD. Since they already have a filesystem image, I just copy the raw filesystem device as it is. This works well, but booting the virtual machine fails, because it does not have an EFI partition. These are regular BIOS bootable instances. This shouldn’t be a problem since Qemu supports booting both BIOS and EFI. But I can’t find a way to convince LXD to use BIOS boot. I tried to add the -bios parameter: lxc config set testvm raw.qemu='-bios /…

In the end I just used raw.qemu instead of raw.qemu.conf.

So all good now with the Dell OME and the Citrix vADC images, which is about all I need because I just doing have the time to get them to work with UEFI and then maintain them. Only thing left to do is making the binary more accessible on the file system to instances rather than putting in the logs dir, but I have bumped into some topics on that.

Thanks so much for the great help and have a wonderful evening!
