To help consolidate the commonality between virDomainHostdevDef and
virDomainNetDef into as few members as possible (and because I
think it makes sense), this patch moves the rombar and bootIndex
members into the "info" member that is common to both (and to all the
other structs that use them).
It's a bit problematic that this gives rombar and bootIndex to many
device types that don't use them, but this is already the case for the
master and mastertype members of virDomainDeviceInfo, and is properly
commented as such in the definition.
Note that this opens the door to supporting rombar for other devices
that are attached to the guest PCI bus - virtio-blk-pci,
virtio-net-pci, various other network adapters - which which have that
capability in qemu, but previously had no support in libvirt.
QEMU supports a bunch of CPUID features that are tied to the kvm CPUID
nodes rather than the processor's. They are "kvmclock",
"kvm_nopiodelay", "kvm_mmu", "kvm_asyncpf". These are not known to
libvirt and their CPUID leaf might move if (for example) the Hyper-V
extensions are enabled. Hence their handling would anyway require some
special-casing.
However, among these the most useful is kvmclock; an additional
"property" of this feature is that a <timer> element is a better model
than a CPUID feature. Although, creating part of the -cpu command-line
from something other than the <cpu> XML element introduces some
ugliness.

Avoid creating an empty <cpu> element when the QEMU command-line simply
specifies the default "-cpu qemu32" or "-cpu qemu64".
This requires the previous patch, which lets us represent "-cpu qemu32"
as <os arch='i686'> in the generated XML.

The qemu32 CPU model is chosen based on the <os arch=...> name when
creating the QEMU command line for a 64-bit host. For the opposite
transformation we can test the guest CPU model for the "lm" feature.
If it is absent, def->os.arch needs to be corrected.

Direct boot (using kernel, initrd, and command line) is used by
virt-install/virt-manager for network install. While any bootindex has
no direct effect since -kernel is always first, we need it as a hint for
SeaBIOS to present disks in the same order as they will be presented
during normal boot.
There was missing capability for blkiotune and thus specifying these
settings caused libvirt to run qemu with invalid parameters and then
reporting qemu error instead of the standard libvirt one. The support
for blkiotune setting was added in upstream qemu repo under commit
0563e191516289c9d2f282a8c50f2eecef2fa773.
This introduces new attribute wrpolicy with only supported
value as immediate. This will be an optional
attribute with no defaults. This helps specify whether
to skip the host page cache.
When wrpolicy is specified, meaning when wrpolicy=immediate
a writeback is explicitly initiated for the dirty pages in
the host page cache as part of the guest file write operation.
Usage:
<filesystem type='mount' accessmode='passthrough'>
<driver type='path' wrpolicy='immediate'/>
<source dir='/export/to/guest'/>
<target dir='mount_tag'/>
</filesystem>
Currently this only works with type='mount' for the QEMU/KVM driver.

In the past we didn't reserve 0:0:2.0 PCI address if there was no video
device assigned to a domain, which made it impossible to add a video
device later on. So we fixed it (commit v0.9.0-37-g7b2cac1) by always
reserving that address. However, that breaks existing domains without
video devices that already have another device assigned to the
problematic address.
This patch reserves address 0:0:2.0 only in case it was not explicitly
assigned to another device, which means libvirt will try to keep this
address free and will not automatically assign it new devices. But
existing domains for which older libvirt already assigned the address to
a non-video device will keep working as they used to work before 0.9.1.
Moreover, users who want to create a domain without a video device and
use its address for another device may do so by explicitly configuring
the PCI address in domain XML.
In case a hypervisor doesn't support the exact CPU model requested by a
domain XML, we automatically fallback to a closest CPU model the
hypervisor supports (and make sure we add/remove any additional features
if needed). This patch adds 'fallback' attribute to model element, which
can be used to disable this automatic fallback.
We can't call qemuCapsExtractVersionInfo() from test code, because it
expects to be able to call the emulator, and for testing we have fake
emulators that can't be executed. For that reason qemuxml2argvtest.c
doesn't call qemuDomainAssignPCIAddresses(), instead it open codes its
own version.
That means we can't call qemuDomainAssignAddresses() from the test code,
instead we need to manually call qemuDomainAssignSpaprVioAddresses().
Also add logic to cope with qemuDomainAssignSpaprVioAddresses() failing,
so that we can write a test that checks for a known failure in there.

The new introduced optional attribute "copy_on_read</code> controls
whether to copy read backing file into the image file. The value can
be either "on" or "off". Copy-on-read avoids accessing the same backing
file sectors repeatedly and is useful when the backing file is over a
slow network. By default copy-on-read is off.
QEMU does not support security_model for anything but 'path' fs driver type.
Currently in libvirt, when security_model ( accessmode attribute) is not
specified it auto-generates it irrespective of the fs driver type, which
can result in a qemu error for drivers other than path. This patch ensures
that the qemu cmdline is correctly generated by taking into account the
fs driver type.

In the past, generic SCSI commands issued from a guest to a virtio
disk were always passed through to the underlying disk by qemu, and
the kernel would also pass them on.
As a result of CVE-2011-4127 (see:
http://seclists.org/oss-sec/2011/q4/536), qemu now honors its
scsi=on|off device option for virtio-blk-pci (which enables/disables
passthrough of generic SCSI commands), and the kernel will only allow
the commands for physical devices (not for partitions or logical
volumes). The default behavior of qemu is still to allow sending
generic SCSI commands to physical disks that are presented to a guest
as virtio-blk-pci devices, but libvirt prefers to disable those
commands in the standard virtio block devices, enabling it only when
specifically requested (hopefully indicating that the requester
understands what they're asking for). For this purpose, a new libvirt
disk device type (device='lun') has been created.
device='lun' is identical to the default device='disk', except that:
1) It is only allowed if bus='virtio', type='block', and the qemu
version is "new enough" to support it ("new enough" == qemu 0.11 or
better), otherwise the domain will fail to start and a
CONFIG_UNSUPPORTED error will be logged).
2) The option "scsi=on" will be added to the -device arg to allow
SG_IO commands (if device !='lun', "scsi=off" will be added to the
-device arg so that SG_IO commands are specifically forbidden).
Guests which continue to use disk device='disk' (the default) will no
longer be able to use SG_IO commands on the disk; those that have
their disk device changed to device='lun' will still be able to use SG_IO
commands.
*docs/formatdomain.html.in - document the new device attribute value.
*docs/schemas/domaincommon.rng - allow it in the RNG
*tests/* - update the args of several existing tests to add scsi=off, and
add one new test that will test scsi=on.
*src/conf/domain_conf.c - update domain XML parser and formatter
*src/qemu/qemu_(command|driver|hotplug).c - treat
VIR_DOMAIN_DISK_DEVICE_LUN *almost* identically to
VIR_DOMAIN_DISK_DEVICE_DISK, except as indicated above.
Note that no support for this new device value was added to any
hypervisor drivers other than qemu, because it's unclear what it might
mean (if anything) to those drivers.
This fixes https://bugzilla.redhat.com/show_bug.cgi?id=638633
Although scripts are not used by interfaces of type other than
"ethernet" in qemu, due to the fact that the parser stores the script
name in a union that is only valid when type is ethernet or bridge,
there is no way for anyone except the parser itself to catch the
problem of specifying an interface script for an inappropriate
interface type (by the time the parsed data gets back to the code that
called the parser, all evidence that a script was specified is
forgotten).
Since the parser itself should be agnostic to which type of interface
allows scripts (an example of why: a script specified for an interface
of type bridge is valid for xen domains, but not for qemu domains),
the solution here is to move the script out of the union(s) in the
DomainNetDef, always populate it when specified (regardless of
interface type), and let the driver decide whether or not it is
appropriate.
Currently the qemu, xen, libxml, and uml drivers recognize the script
parameter and do something with it (the uml driver only to report that
it isn't supported). Those drivers have been updated to log a
CONFIG_UNSUPPORTED error when a script is specified for an interface
type that's inappropriate for that particular hypervisor.
(NB: There was earlier discussion of solving this problem by adding a
VALIDATE flag to all libvirt APIs that accept XML, which would cause
the XML to be validated against the RNG files. One statement during
that discussion was that the RNG shouldn't contain hypervisor-specific
things, though, and a proper solution to this problem would require
that (again, because a script for an interface of type "bridge" is
accepted by xen, but not by qemu).

Currently non-x86 guests must have <acpi/> defined in <features> to

Instead add a capability flag which indicates whether qemu understands

Current versions of qemu always display -no-acpi in their help output,

A preparatory patch for DHCP snooping where we want to be able to
differentiate between a VM's interface using the tuple of
<VM UUID, Interface MAC address>. We assume that MAC addresses could
possibly be re-used between different networks (VLANs) thus do not only
want to rely on the MAC address to identify an interface.
At the current 'final destination' in virNWFilterInstantiate I am leaving
the vmuuid parameter as ATTRIBUTE_UNUSED until the DHCP snooping patches arrive.
(we may not post the DHCP snooping patches for 0.9.9, though)
Mostly this is a pretty trivial patch. On the lowest layers, in lxc_driver
and uml_conf, I am passing the virDomainDefPtr around until I am passing
only the VM's uuid into the NWFilter calls.
This patch cleans up return codes in the nwfilter subsystem.
Some functions in nwfilter_conf.c (validators and formatters) are
keeping their bool return for now and I am converting their return
code to true/false.
All other functions now have failure return codes of -1 and success
of 0.
[I searched for all occurences of ' 1;' and checked all 'if ' and
adapted where needed. After that I did a grep for 'NWFilter' in the source
tree.]
assumptions from generic code.
This implements the minimal set of changes needed in libvirt to launch a
PowerPC-KVM based guest.
It removes x86-specific assumptions about choice of serial driver backend
from generic qemu guest commandline generation code.
It also restricts the ACPI capability to be available for an x86 or
x86_64 domain.
This is not a complete solution -- it still does not guarantee libvirt
the capability to flag non-supported options in guest XML. (Eg, an ACPI
specification in a PowerPC guest XML will still get processed, even
though qemu-system-ppc64 does not support it while qemu-system-x86_64 does.)
This drawback exists because libvirt falls back on qemu to query supported
features, and qemu '-h' blindly lists all capabilities -- irrespective
of whether they are available while emulating a given architecture or not.
The long-term solution would be for qemu to list out capabilities based
on architecture and platform -- so that libvirt can cleanly make out what
devices are supported on an arch (say 'ppc64') and platform (say, 'mac99').

For direct attach devices, in qemuBuildCommandLine, we seem to be freeing
actual device on error path (with networkReleaseActualDevice). But the actual

qemuProcessStop eventually deletes the direct attach device and releases
actual device. But by the time qemuProcessStop is called qemuBuildCommandLine
has already freed actual device, leaving stray macvtap devices behind on error.
So the simplest fix is to remove the networkReleaseActualDevice in

This improves the support for qemu rbd devices by adding support for a few
key features (e.g., authentication) and cleaning up the way in which
rbd configuration options are passed to qemu.
An <auth> member of the disk source xml specifies how librbd should
authenticate. The username attribute is the Ceph/RBD user to authenticate as.
The usage or uuid attributes specify which secret to use. Usage is an
arbitrary identifier local to libvirt.
The old RBD support relied on setting an environment variable to
communicate information to qemu/librbd. Instead, pass those options
explicitly to qemu. Update the qemu argument parsing and tests
accordingly.

Following the renaming of the bridge management APIs, we can now
split the source file into 3 corresponding pieces
* src/util/virnetdev.c: APIs for any type of network interface
* src/util/virnetdevbridge.c: APIs for bridge interfaces
* src/util/virnetdevtap.c: APIs for TAP interfaces

src/uml/uml_driver.c: Update #include directives
The existing brXXX APIs in src/util/bridge.h are renamed to
follow one of three different conventions
- virNetDevXXX - operations for any type of interface
- virNetDevBridgeXXX - operations for bridge interfaces
- virNetDevTapXXX - operations for tap interfaces

* src/lxc/lxc_driver.c, src/network/bridge_driver.c,
src/qemu/qemu_command.c, src/uml/uml_conf.c,
src/uml/uml_driver.c: Update for API renaming
Currently every caller of the brXXX APIs has to store the returned
errno value and then raise an error message. This results in
inconsistent error messages across drivers, additional burden on
the callers and makes the error reporting inaccurate since it is
hard to distinguish different scenarios from 1 errno value.
* src/util/bridge.c: Raise errors instead of returning errnos
* src/lxc/lxc_driver.c, src/network/bridge_driver.c,
src/qemu/qemu_command.c, src/uml/uml_conf.c,
src/uml/uml_driver.c: Remove error reporting code
The bridge management APIs in src/util/bridge.c require a brControl
object to be passed around. This holds the file descriptor for the
control socket. This extra object complicates use of the API for
only a minor efficiency gain, which is in turn entirely offset by
the need to fork/exec the brctl command for STP configuration.
This patch removes the 'brControl' object entirely, instead opening
the control socket & closing it again within the scope of each method.
The parameter names for the APIs are also made to consistently use
'brname' for bridge device name, and 'ifname' for an interface
device name. Finally annotations are added for non-NULL parameters
and return check validation

and update API parameter names & annotations.
