[pve-devel] [PATCH qemu-server 06/22] drive: remove geometry options gone since QEMU 3.1

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

It was not possible to start a QEMU instance with these options set
since QEMU version 3.1, QEMU commit b24ec3c462 ("block: Remove
deprecated -drive geometry options") and thus also not to take a
backup. It is still possible to restore an ancient backup with these
options set and they will be automatically dropped.
