I have a report for 1.20.4 about this error. There is no /etc/lvm/lvm.conf in

Is this caused by either of d8f14591d10df847fad2e24f2f430b2543020912
or 9fd41abd40c3ffc10985e862dc34c868360a1b22?
Do they not have lvm.conf at all, or is it located in /etc/lvm.conf?
$ virt-resize --expand /dev/sda2 in.img out.img
Examining in.img ...
Fatal error: exception Guestfs.Error("lvm_set_filter: open:
/tmp/lvmiUFSBa/lvm/lvm.conf: No such file or directory")
Maybe the callers of lvm_set_filter or lvm_set_filter itself can be
more forgiving.
In this case, lvm_set_filter really needs to edit lvm.conf. It could
be more forgiving by creating a new file with a single 'filter' rule
in it however.
Also lvm-filter is a fairly obscure feature. With a bit of thought we
could probably remove its use from the one remaining place in the
libguestfs code (virt-resize).
