Switching location of default libvirt's pool on Debian forky

Google's AI Assistant brief report some times shows up the command following below : If you need to redefine, use virsh pool-define-as --name default --type  dir --target /new/path/libvirt/images, some time skips it. However, "Dive deeper in AI mode" always point to this command. Same procedure may be also performed via Virt-manager GUI with option "preferences" => XML editing enabled and manually editing path to default pool and restarting daemon libvirtd.

 boris@DebianForky20FB:~$ uname -a

Linux DebianForky20FB 6.19.3 #1 SMP PREEMPT_DYNAMIC Thu Feb 19 13:29:45 EST 2026 x86_64 GNU/Linux

boris@DebianForky20FB:~$ mkdir -p lib/libvirt/images/

boris@DebianForky20FB:~$ sudo virsh pool-destroy default

[sudo] password for boris:

Pool default destroyed

boris@DebianForky20FB:~$ sudo virsh pool-undefine default

Pool default has been undefined

Per my experience next step is a must ( obviously my experience is limited )

boris@DebianForky20FB:~$ sudo virsh pool-define-as --name default --type dir --target /home/boris/lib/libvirt/images

Pool default defined

boris@DebianForky20FB:~$ sudo virsh pool-autostart default

Pool default marked as autostarted

boris@DebianForky20FB:~$ sudo virsh pool-start default

Pool default started

boris@DebianForky20FB:~$ sudo systemctl restart libvirtd

boris@DebianForky20FB:~$ sudo systemctl status libvirtd
