Configuring storage pools

[ncryptid]

When trying to deploy a libvirt machine using this repo's version of the nixops-libvirt plugin, I run into the following error:

example> Connecting to qemu:///system...
example> preparing disk image...
example> 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'

Obviously the issue here is that I have no storage pools on the system:

$ virsh pool-list
 Name   State   Autostart
---------------------------

I could create one manually with virsh, but what I want to know is whether it's currently possible to do this through nix. Adding the following option just returns the same error as above (except 'default' is now '/mnt/vms'), which is what I would expect to happen anyways:

{
   example = {
     deployment = {
       targetEnv = "libvirtd";
       libvirtd = {
         headless = true;
         storagePool = "/mnt/vms";
       };
     };
   };
 }

Thanks

Ran into the same problem. I suspect this bug needs to be filed against nixpkgs though, not this nixops plugin?
