Comment 7 for bug 1801918

Christian, thank you for pointing me in the right direction. Adding

filter = [ "a|/dev/disk/by-path/pci-*|" ]

to /etc/lvm/lvm.conf solved this issue. (There is no need to restart any
service after changing this file. ;))

You can find the thread on the mailing list under this link:
https://www.redhat.com/archives/libvirt-users/2018-October/msg00059.html

I'll add a response there soon.

Best Regards

Jan
