Libguestfs - Apr 2023 - VM name starting with a dash

13:19 < tgolembi[m]> is there a trick how to convert a VM with name that
starts with a dash? It's being confused for virt-v2v argument.
                     :)

Yes you can do this:

$ virt-v2v -o [etc...] -- vmname

Note all -options need to come before the "--".

For example:

$ virt-builder fedora-35
$ mv fedora-35.img ./-fedora-35.img 
$ virt-v2v -i disk -o null -- -fedora-35.img 
[   0.0] Setting up the source: -i disk -fedora-35.img
[etc]

It's quite possible this could hit other corner-cases inside virt-v2v
(eg when running subprocesses), so if you see bugs please file them.

virt-p2v converts physical machines to virtual machines.  Boot with a
live CD or over the network (PXE) and turn machines into KVM guests.

Duh. I didn't see that in the documentation and it didn't occur to me
to try. 

    Thanks
