We were using 'Y' to mean exabyte, when the correct abbreviation would be
'E' ('Y' is yettabyte, which is exabyte * 1024 * 1024). While it isn't
strictly backwards compatible, I highly doubt anyone was actually using
this broken behavior, so I don't see any harm in in dropping 'Y' handling.
Add support for virtio-serial by defining a new 'virtio' channel target type
and a virtio-serial controller. Allows the following to be specified in a
domain:
<controller type='virtio-serial' index='0' ports='16' vectors='4'/>
<channel type='pty'>
<target type='virtio' name='org.linux-kvm.port.0'/>
<address type='virtio-serial' controller='0' bus='0'/>
</channel>

When attaching a USB host device based on vendor/product, libvirt
will resolve the vendor/product into a device/bus pair. This means
that when printing XML we should allow device/bus info to be printed
at any time if present
* src/conf/domain_conf.c, docs/schemas/domain.rng: Allow USB device
bus info alongside vendor/product
The current way of assigning names to the host network backend and
NIC device in QEMU was over complicated, by varying naming scheme
based on the NIC model and backend type. This simplifies the naming
to simply be 'net0' and 'hostnet0', allowing code to easily determine
the host network name and vlan based off the primary device alias
name 'net0'. This in turn allows removal of alot of QEMU specific
code from the XML parser, and makes it easier to assign new unique
names for NICs that are hotplugged
* src/conf/domain_conf.c, src/conf/domain_conf.h: Remove hostnet_name
and vlan fields from virNetworkDefPtr
* src/qemu/qemu_conf.c, src/qemu/qemu_conf.h, src/qemu/qemu_driver.c:

function.
This reverts commit cdc42d0a4865199a941d330dbb6ca1ef426323ae.
As DanB pointed out, this patch is actually wrong. The real
bug that was causing me to see this problem is a bug
introduced in a RHEL-5 libvirt snapshot, and I'm going to
fix the real bug there.

The <console> tag is supposed to result in addition of a single
<serial> device for HVM guests. The 'targetType' attribute was
missing though causing the compatibility code to add a second
<console> device
* src/conf/domain_conf.c: Set targetType for serial device
When libvirtd shuts down, it places a <state/> tag in the XML
state file it writes out for guests with PCI passthrough
devices. For devices that are attached at bootup time, the
state tag is empty. However, at libvirtd startup time, it
ignores anything with a <state/> tag in the XML, effectively
hiding the guest.
This patch remove the check for VIR_DOMAIN_XML_INTERNAL_STATUS
when parsing the XML.
* src/conf/domain_conf.c: remove VIR_DOMAIN_XML_INTERNAL_STATUS
flag check in virDomainHostdevSubsysPciDefParseXML()
Allows the initiator to use a variety of IQNs rather than just the
system IQN when creating iSCSI pools.
* docs/schemas/storagepool.rng: extends the syntax with <iqn name="..."/>
* src/conf/storage_conf.[ch]: read and stores the iqn name
* src/storage/storage_backend_iscsi.[ch]: implement the IQN selection
when detected
* src/conf/domain_conf.c (virDomainChrDefFormat): Plug a leak on
an error path, and at the same time, eliminate the need for a
"cleanup:" block. Before, the "return -1" after the switch
would leak an "addr" string. Now, by reversing the port,addr-
getting blocks we can free "addr" immediately and skip the goto.
The 'int virInterfaceIsActive()' method was directly returning the
value of the 'int active:1' bitfield in virIntefaceDefPtr. A bitfield
with a signed integer, will hold the values 0 and -1, not 0 and +1
as might be expected. This meant that virInterfaceIsActive() was
always returning -1 when the interface was active, not +1 & thus all
callers thought an error had occurred. To protect against this kind
of mistake again, change all bitfields to be unsigned ints
* daemon/libvirtd.h, src/conf/domain_conf.h, src/conf/interface_conf.h,
src/conf/network_conf.h: Change bitfields to unsigned int.
This was accomplished in xml parsing by doing away with the
stripped-down virInterfaceBareDef object, and just always using
virInterfaceDef, but with restrictions in certain places (eg, the type
of subordinate interface allowed in parsing depends on the parent
interface).
xml formatting was similarly adjusted. In addition, the formatting
functions keep track of the level of interface nesting, and insert
extra leading spaces on each line accordingly (using %*s).
The only change in formatted xml from previous (aside frmo supporting
new combinations of interface types) is that the subordinate ethernet
interfaces take up 2 lines rather than one, eg:
<interface type='ethernet' name='eth0'>
</interface>
instead of:
<interface type='ethernet' name='eth0'/>
Currently CPU topology may only be specified together with CPU model:
<cpu match='exact'>
<model>name</model>
<topology sockets='1' cores='2' threads='3'/>
</cpu>
This patch allows for CPU topology specification without the need for
also specifying CPU model:
<cpu>
<topology sockets='1' cores='2' threads='3'/>
</cpu>
'match' attribute and 'model' element are made optional with the
restriction that 'match' attribute has to be set when 'model' is
present.

Although the serial, parallel, chanel, input & fs devices do
not have PCI address info, they can all have device aliases.
Thus it neccessary to associate the virDomainDeviceInfo data
with them all.
* src/conf/domain_conf.c, src/conf/domain_conf.h: Add hooks for
parsing / formatting device info for serial, parallel, channel
input and fs devices.
* docs/schemas/domain.rng: Associate device info with character
devices, input & fs device
This patch introduces the support for giving all devices a short,
unique name, henceforth known as a 'device alias'. These aliases
are not set by the end user, instead being assigned by the hypervisor
if it decides it want to support this concept.
The QEMU driver sets them whenever using the -device arg syntax
and uses them for improved hotplug/hotunplug. it is the intent
that other APIs (block / interface stats & device hotplug) be
able to accept device alias names in the future.
The XML syntax is
<alias name="video0"/>
This may appear in any type of device that supports device info.
* src/conf/domain_conf.c, src/conf/domain_conf.h: Add a 'alias'
field to virDomainDeviceInfo struct & parse/format it in XML
* src/libvirt_private.syms: Export virDomainDefClearDeviceAliases
* src/qemu/qemu_conf.c: Replace use of "nic_name" field with the
standard device alias
* src/qemu/qemu_driver.c: Clear device aliases at shutdown
The PCI device addresses are only valid while the VM is running,
since they are auto-assigned by QEMU. After shutdown they must
all be cleared. Future QEMU driver enhancement will allow for
persistent PCI address assignment
* src/conf/domain_conf.h, src/conf/domain_conf.c, src/libvirt_private.syms
Add virDomainDefClearPCIAddresses() method for wiping out auto assigned
PCI addresses
* src/qemu/qemu_driver.c: Clear PCI addresses at VM shutdown
Existing applications using libvirt are not aware of the disk
controller concept. Thus, after parsing the <disk> definitions
in the XML, it is neccessary to create <controller> elements
to satisfy all requested disks, as per their defined drive
addresses
* src/conf/domain_conf.c, src/conf/domain_conf.h,
src/libvirt_private.syms: Add virDomainDefAddDiskControllers()
method for populating disk controllers, and call it after
parsing disk definitions.
* src/qemu/qemu_conf.c: Call virDomainDefAddDiskControllers()
when doing ARGV -> XML conversion
* tests/qemuxml2argvdata/qemuxml2argv*.xml: Add disk controller
data to all data files which don't have it already
It is perfectly acceptable to have multiple sound devices of
same type in guest configuration. If the underlying hypervisor
does not like this, it is its job to complain, not the XML
parser's
* src/conf/domain_conf.c: Remove hack which deleted duplicated
sound device models.
* tests/xml2sexprdata/xml2sexpr-fv-sound.xml: Remove duplicate
models
* src/conf/domain_conf.c: add defaults for the video device
* src/esx/esx_vmx.[ch]: add VNC support to the VMX handling
* tests/vmx2xmltest.c, tests/xml2vmxtest.c: add tests for the VNC support
This augments virDomainDevice with a <controller> element
that is used to represent disk controllers (e.g., scsi
controllers). The XML format is given by
<controller type="scsi" index="<num>">
<address type="pci" domain="0xNUM" bus="0xNUM" slot="0xNUM"/>
</controller>
where type denotes the disk interface (scsi, ide,...), index
is an integer that identifies the controller for association
with disks, and the <address> element specifies the controller
address on the PCI bus as described in previous commits
The address element can be omitted; in this case, an address
will be assigned automatically.
Most of the code in this patch is from Wolfgang Mauerer's
previous disk controller series
* docs/schemas/domain.rng: Define syntax for <controller>
XML element
* src/conf/domain_conf.c, src/conf/domain_conf.h: Define
virDomainControllerDef struct, and routines for parsing
and formatting XML
* src/libvirt_private.syms: Add virDomainControllerInsert
and virDomainControllerDefFree
When parsing the <disk> element specification, if no <address>
is provided for the disk, then automatically assign one based on
the <target dev='sdXX'/> device name. This provides for backwards
compatability with existing applications using libvirt, while also
allowing new apps to have complete fine grained control.
* src/conf/domain_conf.h, src/conf/domain_conf.c,
src/libvirt_private.syms: Add virDomainDiskDefAssignAddress()
for assigning a controller/bus/unit address based on disk target
* src/qemu/qemu_conf.c: Call virDomainDiskDefAssignAddress() after
generating XML from ARGV
* tests/qemuxml2argvdata/*.xml: Add in drive address information
to all XML files
Add the virDomainDeviceAddress information to the sound, video
and watchdog devices. This means all of them gain the new XML
element
<address .... />
This brings them upto par with disk/net/hostdev devices which
already have address info
* src/conf/domain_conf.h: Add virDomainDeviceAddress to sound,
video & watchdog device struts.
* src/conf/domain_conf.c: Hook up parsing/formatting for
virDomainDeviceAddress in sound, video & watchdog devices
* docs/schemas/domain.rng: Associate device address info
with sound, video & watchdog
Introduce a new structure
struct _virDomainDeviceDriveAddress {
unsigned int controller;
unsigned int bus;
unsigned int unit;
};
and plug that into virDomainDeviceAddress and generates XML that
looks like
<address type='drive' controller='1' bus='0' unit='5'/>
This syntax will be used by the QEMU driver to explicitly control
how drives are attached to the bus
* src/conf/domain_conf.h, src/conf/domain_conf.c: Parsing and
formatting of drive addresses
* docs/schemas/domain.rng: Define new address format for drives
