Have a Fc39 server qemu/kvm virtual machine. Trying to access the
filesystem from the host machine. The following commands---
:~# modprobe nbd max_part=8
:~# qemu-nbd --connect=/dev/nbd0 /var/lib/libvirt/images/Fed39.qcow2
:~# fdisk /dev/nbd0 -l
Disk /dev/nbd0: 60 GiB, 64424509440 bytes, 125829120 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 131072 bytes
Disklabel type: gpt
Disk identifier: 3B52A5A1-29BD-436B-8145-EEF27D9EFC97

Found volume group "fedora_hpz440" using metadata type lvm2
WARNING: Couldn't find device with uuid
IrbzRo-h3Fw-7s0X-3x1q-NONl-TE3b-iUeftd.
WARNING: VG sysvg is missing PV IrbzRo-h3Fw-7s0X-3x1q-NONl-TE3b-iUeftd
(last written to /dev/sdb).
Found volume group "sysvg" using metadata type lvm2
The missing PV in sysvg is a separate qcow2 file. Just need access to
the first. Is there a way to access the group from the host?
