Most standard Linux utilities that refer to block devices, allow you to
specify by uuid as well (mount, cryptsetup are two examples).

The documentation for qvm-block is sparse, but probably because it's a
striaght-forward utility.

There's no support in qvm-block to assign a device to a VM by UUID, is there?

Could be handy for some of the automation I'd like to put in place on
firing up the system.

One can always lsblk|grep|sed|cut|whatever in a sh script, and then use
the resulting block device for qvm-block, but it'd be a lot cleaner and
less error-prone if one could say

"qvm-block -a Florp UUID=kasdjflaksjdfaklsdf"
or "qvm-block -a FLorp --uid asdfkasjdlfkajsd"

Just a suggestion. (And for any other qvm-* that refer to block devices,
perhaps.)

Cheers.
