Thanks for your explanation. Until now I just filteres the guests' PVs on the host on the "human interface level" by simply ignoring them, but yours is definitely the cleaner and more secure way. Maybe I missed something, but in what way is it easier to partition each and every LV one wants to use as a PV in a guest than to specify a proper filter in /etc/lvm/lvm.conf once? I use a consistent naming scheme for the lv's like /dev/vg_<number>/lv_virt_<hostname> and use the filter filter = [ "r|/dev/vg_\d+/lv_virt_\.*|" ] to ignore all the guest's PVs. Is there any downside in doing that, or are there any advantages in using partitions instead of raw 'devices' for the PVs?
