qemu: add separate rerror_policy for disk errors Previously libvirt's disk device XML only had a single attribute, error_policy, to control both read and write error policy, but qemu has separate options for controlling read and write. In one case (enospc) a policy is allowed for write errors but not read errors. This patch adds a separate attribute that sets only the read error policy. If just error_policy is set, it will apply to both read and write error policy (previous behavior), but if the new rerror_policy attribute is set, it will override error_policy for read errors only. Possible values for rerror_policy are "stop", "report", and "ignore" ("report" is the qemu-controlled default for rerror_policy when error_policy isn't specified). For consistency, the value "report" has been added to the possible values for error_policy as well.

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.

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.

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>

qemu: parse -device virtio-balloon There are no options to parse here other than the name of the device, and all three possible device names have the same prefix ("virtio-balloon" with "-ccw", "-pci", or "-device" appended), so the code is fairly simple. It has been implemented such that it will be easier to add handling for other -device entries that aren't otherwise recognized - just add another "else if (STRPREFIX(opts, ....)" clause. qemuParseCommandLineString() previously would always add a <memballoon model='virtio'/> to every result (the comments erroneously say that it is adding a <memballoon model='none'/>) This has been changed to add model='none', and 84 test case xml's updated accordingly (so that qemuxml2argvtest won't fail). Now that the memballoon device is properly parsed, we can safely add a test for properly ignoring -nodefconfig and -nodefaults. Rather than adding an entire new test case for this (and memballoon), we just randomly pick the clock-utc test and modify it slightly to fulfill the purpose.
