When I verify my backups, it happens ~instantaneously. It used to take

Unless something has changed with how Qubes verifies its backups, there
may be a bug that causes verification to only check dom0, rather than
verifying the AppVMs as well.

This is really bad, because what I care about is the data in the
AppVMs... being able to restore the AppVMs is more important than being
able to restore dom0!

Here's how I back up:
nice qvm-backup \
     --verbose \
     --passphrase-file $PASSFILE \
     --exclude $IGNORE_VM \
     --dest-vm $DEST_VM \
     --compress \
     --yes \

And here's how I restore:
qvm-backup-restore \
     --dest-vm $DEST_VM \
     --passphrase-file $PASSFILE \
     --verify-only \
     --verbose \

When it starts restoring, it shows that none of my VMs will be restored,
except for dom0:
The following VMs are included in the backup:

------------------------+--------------+-------------------+-----------------+--------+                    name |         type |          template | netvm |  label | ------------------------+--------------+-------------------+-----------------+--------+                    dom0 |      AdminVM |               n/a | (default) |  black |                    myvm | StandaloneVM |               n/a | my-net-vm-xxxxx | orange | <-- Excluded from restore     my-other-vm-xxxxxxx |        AppVM |         debian-10 | (default) |   blue | <-- Excluded from restore           another-vm-xx |        AppVM |         fedora-33 | (default) |  green | <-- Excluded from restore
       [... continuing for the list of all VMs ...]

And in fact only dom0 gets verified, the others seem to be ignored.

I cannot seem to reproduce this. My verify-only attempts also verify domUs. I'm using the same qvm-backup-restore command, just without `--verbose`.
