F25 libvirtd complains unsupported config, can't find a VG

[Chris Murphy <lists@xxxxxxxxxxxxxxxxx>]

i'm seeing this in the journal.

find any matching source devices for logical volume group 'vg'

I'm also seeing the VG, which is named 'vg' inactive in virt-manager >
Edit > Connection Details > Storage and it can't be made active, I get
an error:

Error starting pool 'vg': unsupported configuration: cannot find any
matching source devices for logical volume group 'vg'

Traceback (most recent call last):

libvirtError: unsupported configuration: cannot find any matching

However, if I use virsh edit and just specify path to any LV on this
VG, the VM works and uses it without complains.

Soo....it's active as far as LVM is concerned but libvirtd won't
"manipulate" this pool even though it'll use LV's in it, for reasons I
can't figure out.

[root@f25h ~]# pvs
  PV             VG Fmt  Attr PSize  PFree
  /dev/nvme0n1p7 vg lvm2 a--  80.43g 47.43g

[root@f25h ~]# vgs
  VG #PV #LV #SN Attr   VSize  VFree
  vg   1   2   0 wz--n- 80.43g 47.43g


Any ideas?
