Add second drive with 32-64MB size. Create ESP partition there. Install
grub-efi. Power off, switch to UEFI mode, power on, boot to grub-efi.
Much easier than with real hardware machines where you indeed need to
play with partitions. On my laptop I have space available in /boot/
partition so could shrink it and create ESP from there. But already have
ESP so no need.
It's not that simple, in many cases. For example, both the virtualization
setup I use at work, and my home virtualization setup, employs iSCSI so that I
can migrate VMs between my various virtualization hosts.
In order to create a new drive, I'd have to create a new LUN just for a
32-64MiB block device.. Not impossible by any means, but not as simple as the
above. This would be similarly "more complex" in OpenStack environments.
