docs: Fix XML schema handling of LUN address in hostdev tag Defining a domain with a SCSI disk attached via a hostdev tag and a source address unit value longer than two digits causes an error when editing the domain with virsh edit, even if no changes are made to the domain definition. The error suggests invalid XML, somewhere: # virsh edit lmb_guest error: XML document failed to validate against schema: Unable to validate doc against /usr/local/share/libvirt/schemas/domain.rng Extra element devices in interleave Element domain failed to validate content The virt-xml-validate tool fails with a similar error: # virt-xml-validate lmb_guest.xml Relax-NG validity error : Extra element devices in interleave lmb_guest.xml:17: element devices: Relax-NG validity error : Element domain failed to validate content lmb_guest.xml fails to validate The hostdev tag requires a source address to be specified, which includes bus, target, and unit address attributes. According to the SCSI Architecture Model spec (section 4.9 of SAM-2), a LUN address is 64 bits and thus could be up to 20 decimal digits long. Unfortunately, the XML schema limits this string to just two digits. Similarly, the target field can be up to 32 bits in length, which would be 10 decimal digits. # lsscsi -xx [0:0:19:0x4022401100000000] disk IBM 2107900 3.44 /dev/sda # lsscsi [0:0:19:1074872354]disk IBM 2107900 3.44 /dev/sda # cat lmb_guest.xml <domain type='kvm'> <name>lmb_guest</name> <memory unit='MiB'>1024</memory> ...trimmed... <devices> <controller type='scsi' model='virtio-scsi' index='0'/> <hostdev mode='subsystem' type='scsi'> <source> <adapter name='scsi_host0'/> <address bus='0' target='19' unit='1074872354'/> </source> </hostdev> ...trimmed... Since the reference unit and target fields are used in several places in the XML schema, create a separate one specific for SCSI Logical Units that will permit the greater length. This permits both the validation utility and the virsh edit command to succeed when a hostdev tag is included.

tests: unify qemu binary paths for all qemu related tests Our test data used a lot of different qemu binary paths and some of them were based on downstream systems. Note that there is one file where I had to add "accel=kvm" because the qemuargv2xml code parses "/usr/bin/kvm" as virt type="kvm". Signed-off-by: Pavel Hrdina <phrdina@redhat.com>

device: cleanup input device code The current code was a little bit odd. At first we've removed all possible implicit input devices from domain definition to add them later back if there was any graphics device defined while parsing XML description. That's not all, while formating domain definition to XML description we at first ignore any input devices with bus different to USB and VIRTIO and few lines later we add implicit input devices to XML. This seems to me as a lot of code for nothing. This patch may look to be more complicated than original approach, but this is a preferred way to modify/add driver specific stuff only in those drivers and not deal with them in common parsing/formating functions. The update is to add those implicit input devices into config XML to follow the real HW configuration visible by guest OS. There was also inconsistence between our behavior and QEMU's in the way, that in QEMU there is no way how to disable those implicit input devices for x86 architecture and they are available always, even without graphics device. This applies also to XEN hypervisor. VZ driver already does its part by putting correct implicit devices into live XML. Signed-off-by: Pavel Hrdina <phrdina@redhat.com>
