Tested-by: Friedrich Weber <f.weber@proxmox.com>
- created an OVMF VM with its EFI disk on an RBD storage with KRBD enabled
- with qemu-server=9.0.8, after starting the VM spends ~8 seconds in the
"Guest has not initialized the display (yet)" stage before booting
- with this patch on top, the VM boots immediately
