qemu: domain I/O asynchronous handling For virtio disks and interfaces, qemu allows users to enable or disable ioeventfd feature. This means, qemu can execute domain code, while another thread waits for I/O event. Basically, in some cases it is win, in some loss. This feature is available via 'ioeventfd' attribute in disk and interface <driver> element. It accepts 'on' and 'off'. Leaving this attribute out defaults to hypervisor decision.

qemu: assume -uuid is always available The -uuid arg was added in QEMU 0.10.0, so the QEMU driver can assume it is always available. Signed-off-by: Daniel P. Berrange <berrange@redhat.com>

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'. (scaledInteger): New define. * docs/schemas/storagevol.rng (sizing): Use it. * docs/schemas/storagepool.rng (sizing): Likewise. * docs/schemas/domaincommon.rng (memoryKBElement): New define; use for memory elements. * src/conf/storage_conf.c (virStoragePoolDefFormat) (virStorageVolDefFormat): Likewise. * src/conf/domain_conf.h (_virDomainDef): Document unit used internally. * src/conf/storage_conf.h (_virStoragePoolDef, _virStorageVolDef): Likewise. * tests/*data/*.xml: Update all tests. * tests/*out/*.xml: Likewise. * tests/define-dev-segfault: Likewise. * tests/openvzutilstest.c (testReadNetworkConf): Likewise. * tests/qemuargv2xmltest.c (blankProblemElements): Likewise.

numad: Always output 'placement' of <vcpu> <vcpu> is not an optional node. The value for its 'placement' actually always defaults to 'static' in the underlying codes. (Even no 'cpuset' and 'placement' is specified, the domain process will be pinned to all the available pCPUs).

tests: qemuxml: Remove prehistoric machine types from legacy tests None of the tests depend on anything that the machine type would influence. This will allow us to drop the very old machine type from the non-real-data tests. If something depends on the machine type it should be tested with real data rather than this hack.

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>

conf: Introduce new attribute for device address format * src/conf/domain_conf.h: Add new member "target" to struct _virDomainDeviceDriveAddress. * src/conf/domain_conf.c: Parse and format "target" * Lots of tests (.xml) in tests/domainsnapshotxml2xmlout, tests/qemuxml2argvdata, tests/qemuxml2xmloutdata, and tests/vmx2xmldata/ are modified for newly introduced attribute "target" for address of "drive" type.

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.
