“VE” is just the product name of Proxmox’s virtual machine platform, afaik it’s not a technology you can use “in proxmox”. PVE always uses QEMU-KVM virtual machines when it manages a virtual machine.

The other thing PVE can manage is LXC containers.

I haven’t used the LXC part of PVE yet, but frigate it runs relatively fine on CPU here in a VM, as I don’t have devices useful for acceleration. But if you are ready to delve into LXC that could be better performance-wise.

if it doesn’t do card, it’s not an alternative anyway

and I think it would be actually very useful if people made use of that setting

Unfortunately that’s not the case. there are many who don’t understand what’s that after the weird “a”

While we are here: what do you think about unattended updates on Debian and such? (as such being derivatives, including Proxmox VE)
