[server] server upgrade

hello All,

I have a dedicated virtualizer running Ubuntu server 14.04 with KVM.

Trusty is past end-of-life, so I would like to upgrade it (maybe I should wait for 20.04LTS).

The images are on a dedicated disk partition, mounted on /var/lib/libvirt/images.

I was thinking to upgrade the server to 18.04 over a weekend, office closed, turning off previously all guest machines.

Then I would simply install the host over the original / partition, avoiding (of course!) to format the images' partition.

I probably would need to backup and restore the other folders in /var/lib/libvirt.

Am I making things too simple...?

Thanks for your advice,

best,

Gian
