February 8, 20197 yr I got a VM running on unraid 6.7.0-rc2, and I am trying to move it to another server, also running 6.7.0-rc2. After a lot of searching, I have found different answers on how to do it, but I can't get any of them to work. Some say to just create a VM on the new server, then replace the img file with the one from the old server. Others say to just take all the XML from one server and use it to make a new VM on the new server... But none of them work. When I take all the XML, it gives me an error about missing some OVMF. And if I modify it to use the same OVMF path as on the new server, I just end in Shell> without booting the VM. If I change the bios over to SeaBIOS, it just stalls at "Booting from harddrive...". What should I do to do it correct? And can it be done? (I hope it can, one of the things running in that vm is a pain in the butt to set up and get working properly)
February 10, 20197 yr Copy the img file from server a to server b. On server b, create a new vm and put your settings as whatever. If the img was ovmf, use that (same as seabio). When you get to the part about hard drive/img, switch to manual and specify the location of the img you copied over. Finish setting anything else. Then start. thsts it. I do it all the time. note: if you drop into the shell, type exit (iirc) which will bring you tj the boot/bios menu. Specify the img file to boot from and then you’ll be on your way.

If you do that with a Windows VM does Windows complain about its licence key being in use on another machine and need you to re-register?

I found a place under maintenance, and from there I could select the file, but it only said new file and new folder. At the bottom there is an EFI option, select that, then go into the folders it finds, and select the image. When you select it, it boots the VM right away, but on next boot it isn't finding it again. To get it to auto boot, you need to find the menu for adding a boot option, then do the same with EFI again, and find the image, give the boot option a name, and then go back and change the boot order, and move the image up to the top. Commit and exit.

That’s a good question. If it does, you could always go back and copy the nvram from the old server to the new one, and make sure the uuid matches the original. Then it would essentially be the the same I believe, alleviating the problem.
February 10, 20197 yr OK. Thanks @1812. I'm going to have to research that. I'm not sure where the nvram is stored. I'm not a big VM user.
