[PATCH qemu-server 0/2] use configured serial as SCSI device ID

["Michael Köppl" <m.koeppl@proxmox.com>]

Since the switch to '-blockdev' with machine version 10.0, SCSI disks
always get the drive name (e.g. 'drive-scsi1') as device ID, even if a
serial is configured. The /dev/disk/by-id paths in the guest therefore
no longer contain the serial, and in a guest running Proxmox VE, the
disk list API endpoint does not report it either.

1/2 sets the device ID explicitly to the configured serial. Unlike
QEMU's default, this also works for serials longer than 20 bytes. The
change is tied to the new machine version 11.1+pve1, which only VMs
with a SCSI disk with a serial require.

2/2 also adds cfg2cmd tests for both sides of the version check.

Tested this on my local test node with explicitly set machine versions
11.1 and 11.1+pve1 as well as latest. Checked that serials longer than
20 bytes are accepted and the VM starts and that with versions older
than 11.1+pve1, the drive name was used, as before.
