@zem congrats! Did you install over the serial port, or created an image in a different way?
@darkstar It is an existing image which already runs on the old server with libvirtd/kvm. I modified /etc/default/grub, (tested with virt-manager serial console) and copied the .qcow2 image to the replacement server.
@darkstar It worked so amazingly easy that I probably won't bother fixing up the installers and just create a bunch of template images.
@zem Thanx for your reply. You inspired me to try the same route :)
this VM is using 45 M of memory which is half of what it used before I copied it over, I should probably consider serial consoles as space saver in my other cloud/virtual setups, too. 🤔
