So, I already extracted the code that formats the attributes which
should be actually done for the frontend few months ago, but did not
swithc to it since I did not want to check when everything was added.
The fix will be rather simple if we are certain that the disk serial,
geometry and error policies were supported in qemu 1.5. In that case we
can switch unconditionally to the new format.
The CHS device properties are available since QEMU v1.2:
- IDE:
https://git.qemu.org/?p=qemu.git;a=commitdiff;h=ba801960
- SCSI:
https://git.qemu.org/?p=qemu.git;a=commitdiff;h=d252df48
- virtio-blk:
https://git.qemu.org/?p=qemu.git;a=commitdiff;h=e63e7fde2
The "serial" property and the PCI "addr" property are also available
since 2012 at least, I didn't fully track their origins, but QEMU v1.2
already supported them.
So yes, all these properties should be available in QEMU 1.5 already.
