conf: better <disk> interleaving in schema In general, we try to make virt-xml-validate tolerant of input elements in any order when possible. However, as written, the RNG grammar did not permit <source> unless there was an explicit type= attribute (even though the C code manages just fine by defaulting to type='file'). After making the attribute optional on the 'file' branch, I noticed that the use of diskspec was now redundant with the branch when no <source> was supplied.

disk: Disallow duplicated target 'dev' values https://bugzilla.redhat.com/show_bug.cgi?id=1142631 This patch resolves a situation where the same "<target dev='$name'...>" can be used for multiple disks in the domain. While the $name is "mostly" advisory regarding the expected order that the disk is added to the domain and not guaranteed to map to the device name in the guest OS, it still should be unique enough such that other domblk* type operations can be performed. Without the patch, the domblklist will list the same Target twice: $ virsh domblklist $dom Target Source ------------------------------------------------ sda /var/lib/libvirt/images/file.qcow2 sda /var/lib/libvirt/images/file.img Additionally, getting domblkstat, domblkerror, domblkinfo, and other block* type calls will not be able to reference the second target. Fortunately, hotplug disallows adding a "third" sda value: $ qemu-img create -f raw /var/lib/libvirt/images/file2.img 10M $ virsh attach-disk $dom /var/lib/libvirt/images/file2.img sda error: Failed to attach disk error: operation failed: target sda already exists $ BUT, it since 'sdb' doesn't exist one would get the following on the same hotplug attempt, but changing to use 'sdb' instead of 'sda' $ virsh attach-disk $dom /var/lib/libvirt/images/file2.img sdb error: Failed to attach disk error: internal error: unable to execute QEMU command 'device_add': Duplicate ID 'scsi0-0-1' for device $ Since we cannot fix this issue at parsing time, the best that can be done so as to not "lose" a domain is to make the check prior to starting the guest with the results as follows: $ virsh start $dom error: Failed to start domain $dom error: XML error: target 'sda' duplicated for disk sources '/var/lib/libvirt/images/file.qcow2' and '/var/lib/libvirt/images/file.img' $ Running 'make check' found a few more instances in the tests where this duplicated target dev value was being used. These also exhibited some duplicated 'id=' values (negating the uniqueness argument of aliases) in the corresponding .args file and of course the *xmlout version of a few input XML files.

tests: qemuxml2xml: assign device addresses We use the PreFormat callback for this. Many test cases need to be extended to pass in proper qemuCaps flags so AssignAddresses doesn't throw errors. One test case (pcie-root-port-too-many) is dropped, since it was meant only for checking an error condition in qemuxml2argv, and one we add in AssignAddresses it errors here too. Long term I think AssignAddresses should be handled in qemu's PostParse callback, but that's not entirely straightforward. Handling it here means we can get the test suite churn over with.

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>
