Storage pool not found: no storage pool with matching name 'default'

[onny]

Hey, I tried to use and install the example with NixOpsUnstable. Unfortunately it fails with this error:

machine> uploading disk image...
libvirt: Storage Driver error : Storage pool not found: no storage pool with matching name 'default'

libvirt.libvirtError: Storage pool not found: no storage pool with matching name 'default'

But storage pool default is present and active.

onny@tuxzentrale ~/p/nixops-libvirtd (master) [1]> virsh pool-list
 Name          State    Autostart
-----------------------------------
 default       active   yes
 gnome-boxes   active   yes

Also redefining default doesn't solve the problem.

virsh pool-destroy default
virsh pool-undefine default
virsh pool-define-as --name default --type dir --target /var/lib/libvirt/images
virsh pool-autostart default
virsh pool-start default

I also tried a different name images but that doesn't help :(

Best regards Jonas

That's strange, the default connection for virsh is not qemu://system? Because this connection list different defined pools :O

onny@tuxzentrale ~/p/nixops-libvirtd (master)> virsh pool-list --all
 Name          State    Autostart
-----------------------------------
 gnome-boxes   active   yes
 images        active   yes

onny@tuxzentrale ~/p/nixops-libvirtd (master)> virsh -c qemu:///system pool-list --all
 Name          State    Autostart
-----------------------------------
 ExamplePool   active   yes

Okay there seems to be one user specific qemu:///session instance and an other qemu:///system instance. In my opinion the tutorial here should be more precise about that :)

[onny]

Okay if you run virsh with sudo it automatically chooses qemu:///system so the tutorial/example is correct :+1:
