xml: output memory unit for clarity Make it obvious to 'dumpxml' readers what unit we are using, since our default of KiB for memory (1024) differs from qemu's default of MiB; and differs from our use of bytes for storage. Tests were updated via: $ find tests/*data tests/*out -name '*.xml' | \ xargs sed -i 's/<\(memory\|currentMemory\|hard_limit\|soft_limit\|min_guarantee\|swap_hard_limit\)>/<\1 unit='"'KiB'>/" $ find tests/*data tests/*out -name '*.xml' | \ xargs sed -i 's/<\(capacity\|allocation\|available\)>/<\1 unit='"'bytes'>/" followed by a few fixes for the stragglers. Note that with this patch, the RNG for <memory> still forbids validation of anything except unit='KiB', since the code silently ignores the attribute; a later patch will expand <memory> to allow scaled input in the code and update the RNG to match. * docs/schemas/basictypes.rng (unit): Add 'bytes'.

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>

domain: add implicit USB controller Some tools, such as virt-manager, prefers having the default USB controller explicit in the XML document. This patch makes sure there is one. With this patch, it is now possible to switch from USB1 to USB2 from the release 0.9.1 of virt-manager. Fix tests to pass with this change.

Auto-add disk controllers based on defined disks Existing applications using libvirt are not aware of the disk controller concept. Thus, after parsing the <disk> definitions in the XML, it is neccessary to create <controller> elements to satisfy all requested disks, as per their defined drive addresses * src/conf/domain_conf.c, src/conf/domain_conf.h, src/libvirt_private.syms: Add virDomainDefAddDiskControllers() method for populating disk controllers, and call it after parsing disk definitions. * src/qemu/qemu_conf.c: Call virDomainDefAddDiskControllers() when doing ARGV -> XML conversion * tests/qemuxml2argvdata/qemuxml2argv*.xml: Add disk controller data to all data files which don't have it already

qemu: auto-add pci-root controller for pc machine types <controller type='pci' index='0' model='pci-root'/> is auto-added to pc* machine types. Without this controller PCI bus 0 is not available and no PCI addresses are assigned by default. Since older libvirt supported PCI bus 0 even without this controller, it is removed from the XML when migrating.

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>

Explicitly represent balloon device in XML and handle PCI address To allow compatibility with older QEMU PCI device slot assignment it is necessary to explicitly track the balloon device in the XML. This introduces a new device <memballoon model='virtio|xen'/> It can also have a PCI address, auto-assigned if necessary. The memballoon will be automatically added to all Xen and QEMU guests by default. * docs/schemas/domain.rng: Add <memballoon> element * src/conf/domain_conf.c, src/conf/domain_conf.h: parsing and formatting for memballoon device. Always add a memory balloon device to Xen/QEMU if none exists in XML * src/libvirt_private.syms: Export memballoon model APIs * src/qemu/qemu_conf.c, src/qemu/qemu_conf.h: Honour the PCI device address in memory balloon device * tests/*: Update to test new functionality
