Hi, I am trying to create a logical volume storage pool with persistent device names for the block devices, because I can't/don't want to ensure that /dev/sd* names are persistent through reboots. virsh # pool-define-as web2067 logical - - /dev/disk/by-path/pci-0000:18:00.0-scsi-0:2:2:0 web2067 /dev/web2067 virsh # pool-build web2067 These two steps work as expected and the pv and the vg get created, but when I try to start the pool I get the following error: virsh # pool-start web2067 error: Failed to start pool web2067 error: unsupported configuration: cannot find any matching source devices for logical volume group 'web2067' If I do the same steps just with /dev/sdX instead of /dev/disk/by-path/..., the pool gets created correctly. This looks like a bug for me or am I wrong? If this is the case, is this and known issue and fixed in later versions? I am running Ubuntu 18.04 with libvirt in version 4.0.0. Best Regards Jan
