[pve-devel] [PATCH qemu-server 10/15] blockdev: add support for 'size' option

[Fiona Ebner <f.ebner@proxmox.com>]

For EFI disks in raw format, it is necessary to specify a precise size
and have no padding. See commit 818ce80e ("fix efidisks on storages with
minimum sizes bigger than OVMF_VARS.fd") for details.
