I was directed to this mailing-list by someone on the spice-devel
mailing-list (that exchanged is an attachment in this email).
With their help I've managed to get virt-viewer and remote-viewer
working as a single flatpak. If the user runs
`flatpak run org.virt_manager.virt-viewer`
they get `virt-viewer`, a `.desktop` entry also exists for
`remote-viewer`, which
is how remote-viewer is launched (like any other app on the system).
I started flatpaking virt-viewer and remote-viewer because I use Fedora
Atomic Workstation
(now named SilverBlue I think) and it recommends the use of packages
packaged as flatpaks.
My git repo can be found:
- https://github.com/adriankoshka/flathub/tree/org.virt_manager.virt-viewer
and my PR to flathub (a central repository of flatpak apps which makes
it easier to distribute flatpak apps):
- https://github.com/flathub/flathub/pull/391
I still need to work out some issues like:
- connecting to qemu:///system with virt-viewer (right now
qemu+ssh://user@ip/system works, I need to figure out how to pass the
host libvirt socket to the flatpak sandbox)
- USB redirection (It seems /dev within the flatpak is read-only, I'm
trying to find someone knowledgeable about how /dev is done within
flatpak's sandbox)
Some things I haven't tested:
- connecting to a VNC client
- WebDAV
- SASL
- building the flatpak for i386/arm/aarch64
I hope I've made a useful contribution by attempting to flatpak
virt-viewer and remote-viewer.

Thanks for pointing out the prefix thing with libvirt, and pointing me
to the correct mailing-list.

I've hit a bit of a snag with virt-viewer. I've got it compiled, running,
but whenever I try to connect to a remote instance, I always get this:

Connecting to that URI via virt-manager on the same machine just works. I
just don't know what I'm doing wrong.
Here is my current flatpak manifest:
https://github.com/AdrianKoshka/flathub/blob/org.virt_manager.virt-viewer/org.virt_manger.virt-viewer.json
You are not settig the paths for building libvirt, so it will default
to /usr/local, but all the versions built by distros will use
--prefix=/usr --sysconfdir=/etc --localstatedir=/var.
Thus it will be trying to run netcat with the wrong socket path
eg /usr/local/var/run/libvirt/libvirt-sock, instead of
/var/run/libvirt/libvirt-sock
BTW, the mailing list for virt-viewer is actually the virt-tools-list
https://virt-manager.org/communicate/

Daniel
