RHEL 10 announced that RDP would be the preferred alternative to VNC. Red Hat replaced Spice with VNC in Red Hat 8 due to licensing issues with h.246. VNC is under featured and basic compared to both alternatives. Spice uses proprietary h.246 which caused disputes with licenses. RDP is proprietary to microsoft but has a few foss implementations.
Spice is slow as fuck too. It was so agonizing using my Windows VM (for Affinity Publisher) on Gnome Boxes because it requires Spice tools since the networking isn’t bridged by default for whatever reason and you can’t enable it without a bunch of fucking around, so network shares don’t function. Everything is done via Spice WebDAV, which gets disconnected every couple of minutes, freezing the VM filesystem while the Windows VM figures out wtf to do with itself and reconnects everything. It’s atrocious.
Eventually I spent the time needed to fiddle with the VM in Virtual Machine Manager and set up bridged networking. Now I can use normal network shares and it’s so much faster and more reliable.
I know this thread is supposed to be about the remote access parts of it, but Spice is damned annoying, in my experience. I don’t even want to be using a Windows VM anyway, the last thing I need is slow file sharing with my host OS.
Every time I try to use Gnome boxes I walk away frustrated and confused. I thought it was just an alternative GUI that did the same thing as VirtManager. It’s doing something behind the scenes that is very different and not perfermant. I use spice with VirtManager daily and I don’t have issues, but I’m not using the spice webdav stuff either, just display I think.
