qemu: Allow serving VNC over a unix domain socket QEMU supports serving VNC over a unix domain socket rather than traditional TCP host/port. This is specified with: <graphics type='vnc' socket='/foo/bar/baz'/> This provides better security access control than VNC listening on 127.0.0.1, but will cause issues with tools that rely on the lax security (virt-manager in fedora runs as regular user by default, and wouldn't be able to access a socket owned by 'qemu' or 'root'). Also not currently supported by any clients, though I have patches for virt-manager, and virt-viewer should be simple to update. v2: schema: Make listen vs. socket a <choice>

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.

tests: fix name of 32-bit x86 QEMU binary The 32-bit x86 binary is called qemu-system-i386, not qemu-system-i686. This mistake across many test XML files was not noticed because the mistake was also made in testutilsqemu.c when mocking the capabilities.

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.

conf: Add keyboard input device type There is no keyboard support currently in libvirt.

vnc: add support for listen type 'socket' VNC graphics already supports sockets but only via 'socket' attribute. This patch coverts that attribute into listen type 'socket'. For backward compatibility we need to handle listen type 'socket' and 'socket' attribute properly to support old XMLs and new XMLs. If both are provided they have to match, if only one of them is provided we need to be able to parse that configuration too. To not break migration back to old libvirt if the socket is provided by user we need to generate migratable XML without the listen element and use only 'socket' attribute.

video: cleanup usage of vram attribute and update documentation The vram attribute was introduced to set the video memory but it is usable only for few hypervisors excluding QEMU/KVM and the old XEN driver. Only in case of QEMU the vram was used for QXL. This patch updates the documentation to reflect current code in libvirt and also changes the cases when we will set the default vram attribute. It also fixes existing strange default value for VGA devices 9MB to 16MB because the video ram should be rounded to power of two. The change of default value could affect migrations but I found out that QEMU always round the video ram to power of two internally so it's safe to change the default value to the next closest power of two and also silently correct every domain XML definition. And it's also safe because we don't pass the value to QEMU. Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1076098 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.
