Migrating Home Assistant OVA VM from Hyper-V to Proxmox

Now that i have nailed the qm disk import command and given all linux kernel have the virtio drivers in them after 5.6 this should be a breeze!

Export

Export VHD from Hyper-V into share proxmox can see (tbh at this point if you don't know how...)

Create VM on proxmox

I created a 4GB VM with no disks at all andthe virtio network. Make sure you connect it to a live bridge or hass will hand at starting network manager I added a TPM drive I added a U?EFI drive buy unchecked enroll keys (if you forget this the VM will not boot)

Import disk

qm disk import 106 nameofile.vhdx vDisks (imports disk for VM 106 and puts it on my volume called vDisks)

Configure VM with disk

attach the unsued disk make it virtio 0 with whatever settings you like (i enable discard and write through)

Boot VM Machine

It should boot just fine

Change IP address back to whaetver you were using

As adapter changed set hass settings back to original static IP you were using a at hassos console. This means if you were using static you will need to do the instructions below. If you use a DHCP reseveration a) why are you doing that for crtitical machines... dhcp goes down your crtitical machines go down.. b) instead of doing instructions below you can give the network card for the vm in proxmox same MAC as the reservation already has!
