How to use the VM's on the Host machine? (not VNC)

Hi all,

So I setup proxmox on a host + have all my VM’s (Linux, windows + Mac) working. I can access from the web browser / VNC fine.

Now it’s setup, I’d like to boot the machine and work on IT rather than through VNC from another machine, but I can’t for the life of me figure out how!
Is it possible to add my windows / Linux / Mac VM’s to the grub bootloader on the Host? (I can't find any info or tutorial to do this)

I feel somewhat silly asking this question, but hope someone can point me in the right direction! (Or did I completely miss the approach proxmox was designed to be used?)

TIA!

Jup. PVE is meant to be used headless.

If you don't want to install a desktop environment to be able to locally VNC into the VMs you would need to use 4 GPUs, passthrough on of them into each of the 3 VMs, connect the 4 GPUs + 4 USB (USB passthrough for keyboard/mouse) to a KVM switch and then use that KVM to switch between VMs and the host, so you only need one display/keyboard/mouse for all 4 machines.
And consumer hardware probably doesn't offer enough PCIe slots that could be used for PCI passthrough of 3 GPUs (or atleast two of those GPUs would only run with 4 PCIe lanes).

Appreciate you taking the time to clarify! It was our first proxmox install hence the confusion.. I WAS considering to plug in directly and configure for pass-through, but as another commenter pointed out, it would result in 4 Gpus .. Once our studio make some more money! ;-) thx again!

Well..., if you are brave you might read https://pve.proxmox.com/wiki/Developer_Workstations_with_Proxmox_VE_and_X11

Of course the different OS's are run as a VM, not native, so performance is okay for most work but not for gaming or video editing or...

I've tried this semi-successfully: it worked, but the whole system is just not optimized for this use-case. Leaving Qubes-OS (https://www.qubes-os.org/faq/) for PVE just didn't cut it (for me).
