“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.
haven’t seen a single source so far for any claims, other then a justin timberlake clip disguised as a source
