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. Thomas
