My GPU is quite literally 15 or 16 years old (I pulled it out of an old server that was being trashed). If you aren’t going to do heavy graphical work and just want to spruce up your desktop performance then really anything is probably fine.

I think both these options require downloading additional libraries on your Proxmox host to work.

Cat tax paid.

Under hardware > display there is an option for VirtiO-GPU and VirGL-GPU. I’m not super knowledgeable but I think these options allows VMs to make system calls to the GPU. I put an ancient Quadro in my server and my RDP sessions were noticeably better.

Setup a virtual desktop on your server and RDP into it to access the web interface. Here is me doing that using my cat as a stand lol.

I’m not sure. All I know is that Proxmox doesn’t recommend using Docker in LXCs. It seems Proxmox has much more control over the internals of the container and can break stuff.

If you want to run application containers, for example, Docker images, it is recommended that you run them inside a Proxmox QEMU VM. This will give you all the advantages of application containerization, while also providing the benefits that VMs offer, such as strong isolation from the host and the ability to live-migrate, which otherwise isn’t possible with containers.

If I had to guess it got damaged when transported in a box with hundreds of pounds of old servers stacked on top of it. Some of the other KVMs I saw were in pieces.

I think this model is roughly $1300 brand new. Mine has some cosmetic damage but I still see used KVMs like this on EBay in the high three digit range.

Mine came from Craigslist. It’s perfect for server stuff.

My cat has claimed it as his own lol

I ran it previously because I came from that world and I just thought that’s what you did. I was less Linux-y then. It’s really overkill for such a small network but if you want to learn AD then it might be worth it. Personally I hope to never look at AD again but alas I need moneyz.

If you do decide to run it make sure you enable profile caching in group policy, it will prevent you from being locked out when your DC is down. Also if you have laptops you can safely bring them outside your network and they will still be able to log in.
