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.
Haven’t watched the video since it’s on YouTube, but I hope this means they’ll start adding features at some point soon after the rewrite is finished. It would be really nice to be able to more easily configure bridged networking in a VM, for instance.
