Snapshots with pci-passthrough possible (getting an error)?

[bleomycin]

I'm attempting to snapshot a pfsense VM running on proxmox version: 3.1-4/f6816604. This VM has a gigabit network card attached to it with pci passthrough and is using a qcow2 containter with an ide interface.

VM config:

bootdisk: virtio0
cores: 1
hostpci0: 07:00.0
ide0: ssd1:110/vm-110-disk-1.qcow2,format=qcow2,size=5G
ide2: none,media=cdrom
memory: 512
name: pfsense386
net0: e1000=2E:51:34:ED:E5:27,bridge=vmbr0
ostype: other
sockets: 1

proxmox throws this error when I try a snapshot:

VM 110 qmp command 'savevm-start' failed - State blocked by non-migratable device '0000:00:10.0/pci-assign'

Thanks for any help!

You cannot create a snapshot if you use pci passthrough.

Ouch, alright I wasn't sure thanks for verifying that for me. Is this a permanent limitation or something that could change in the future?
