I recently updated one of my nodes and a guest that uses mediated passthrough for intel graphics can no longer start.

guest conf:
agent: 1
boot: c
bootdisk: scsi0
cores: 2
cpu: host
hostpci0: 00:02.0,mdev=i915-GVTg_V5_4,rombar=0
machine: q35
memory: 8196
name: jf02
net0: virtio=9E:61:11:45:5C:B4,bridge=vmbr0,firewall=1
numa: 0
ostype: l26
scsi0: local-lvm:vm-100-disk-0,discard=on,size=6888M
scsihw: virtio-scsi-pci
smbios1: uuid=c8334ada-d1f3-4f7c-b535-683f61ba77cd
sockets: 2
vmgenid: df2faf92-2498-438a-a786-01c77a2b676e

and the error I get:
root@pve02:~# qm start 100

kvm: -device vfio-pci,sysfsdev=/sys/bus/pci/devices/0000:00:02.0/00000000-0000-0000-0000-000000000000,id=hostpci0,bus=pci.0,addr=0x10,rombar=0: vfio /sys/bus/pci/devices/0000:00:02.0/00000000-0000-0000-0000-000000000000: no such host device: No such file or directory

This mediated passthrough has worked for a long time now, so I'm not sure where to go with this.
