qemu: support event_idx parameter for virtio disk and net devices In some versions of qemu, both virtio-blk-pci and virtio-net-pci devices can have an event_idx setting that determines some details of event processing. When it is enabled, it "reduces the number of interrupts and exits for the guest". qemu will automatically enable this feature when it is available, but there may be cases where this new feature could actually make performance worse (NB: no such case has been found so far). As a safety switch in case such a situation is encountered in the field, this patch adds a new attribute "event_idx" to the <driver> element of both disk and interface devices. event_idx can be set to "on" (to force event_idx on in case qemu has it disabled by default) or "off" (for force event_idx off). In the case that event_idx support isn't present in qemu, the attribute is ignored (this on the advice of the qemu developer). docs/formatdomain.html.in: document the new flag (marking it as "don't mess with this!" docs/schemas/domain.rng: add event_idx in appropriate places src/conf/domain_conf.[ch]: add event_idx to parser and formatter src/libvirt_private.syms: export virDomainVirtioEventIdx(From|To)String src/qemu/qemu_capabilities.[ch]: detect and report event_idx in disk/net src/qemu/qemu_command.c: add event_idx parameter to qemu commandline when appropriate. tests/qemuxml2argvdata/qemuxml2argv-event_idx.args, tests/qemuxml2argvdata/qemuxml2argv-event_idx.xml, tests/qemuxml2argvtest.c, tests/qemuxml2xmltest.c: test cases for event_idx.

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.

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.
