You cannot boot a VM but you can boot a VHD File! Setup a VM with Hyper-V, prepare a fast usb drive (e.g. nvme stick) with Ventoy and copy Ventoy VHD Plugin and the VHD to the USB Drive.. Then you can boot it on every PC in the world both UEFI and Legacy Boot.. Tried a single Windows VHD with around 20 PCs and Notebooks and it booted on all of them but I ran into problems updating this Windows installation..Boot a VM without an additional host. Boot it directly on the PVE host. Thats my idea.
Ok. After starting a PVE-host i'm able to login in to the console.At least I do not understand what you really want to do here, please try to explain your use case more detailed.
It sounds like he want something like looking glass....Just start the VM. If you want to access the VM console, you need a desktop environment on your Proxmox VE host.
I think your approach - reliability first - is also excellent! What isn't there can't drag the stability down into the basement either.Just start the VM. If you want to access the VM console, you need a desktop environment on your Proxmox VE host.
CALM DOWN!It sounds like he want something like looking glass....
Or to passthrough his gpu with an attached monitor (+keyboard +mouse) to an vm...
Or better said, like hotplug between multiple VM's
Like he runs multiple VM's and want to switch directly between them natively (like the gpu+monitor magically connects to the VM he wants)
However that's impossible anyway, i wouldn't bother spending time here
