Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

You want KVM.
But I'd check the performance on the NAS first. They're not really built for VMs so you might be missing hardware features, but I'd check resource usage to see if you're maxing anything out. And try reducing resolution, color depth, etc. to make it easier.
Well indeed, that's why I want to move the VM off the NAS and onto something with some hardware acceleration. Are there any remote frontend options for KVM?
Proxmox has a full webui with almost every feature you could want, except for some more advanced zfs features
Virtual Machine Manager is what you're looking for I think
Should ask what platform here, IMO: virt-manager is Linux-only. (Or, I suppose, doing remote X stuff to run it elsewhere but that's probably not what OP is after.)
There's some command line stuff you can run on Windows, but then at that point, you can just use virsh on the host itself.
I'm of the opinion that virsh to manage and then a spice or vnc client to access the VMs is the "best" way to go so you're not tied down to having to have a specific OS running a specific tool in order to do any admin stuff, since I mean, after you deploy how often are you screwing with the VM settings?
Good point about platform agnostic remote for management stuff. VNC is ideal for this.
And systems like Proxmox use a web GUI for most stuff, it's a touch slow but I think that's mostly just waiting for the system to finish the actual changes I make, and not the UI.
VNC is not really ideal for anything. For actual desktop usage you want RDP or sunlight/moonshine
You can run virtual manager on other platforms but some features will be missing
There's also Cockpit if you just want a basic UI
I've never liked web UIs that have that level of permissions to screw around with the OS it's hosted on.
Maybe that's just some grumpy greybeard thing, but I'd really rather not have a single management plane that has full access to EVERYTHING, since that just feels like you're one configuration oopsie away from some guy in Albania (<3 you, Albania) uploading all his hentai to your server and then trying to hack the FBI or some shit. (Or, you know, the much more boring oops-i'm-a-zombie-now outcome.)
Uhhhh, why?
Why what?
Why would this person want KVM? They don't need anything a full VM provides, they're just trying to run many services easily on a single host.
They already have several VMs, containers, and want a full desktop on one. If it sounded like going down to one physical server would be appropriate, I would have recommended it. But condensing whatever they've got now would be a huge pain, especially if they find out it doesn't work and they have to start over and go back to VMs and containers.
See your own answer for why that isn't needed.
It's not needed because it's currently mostly working for them? You're going to need to use full sentences if you want to communicate, I'm afraid.
You altered, bruh? Read the response. No idea what you're talking about.
