The output of vcpupin and emulatorpin for a domain with vcpu
placement='static' is based on a default bitmap that contains
all possible CPUs in the host, regardless of the CPUs being offline
or not. E.g. for a Linux host with this CPU setup (from lscpu):
On-line CPU(s) list: 0,8,16,24,32,40,(...),184
Off-line CPU(s) list: 1-7,9-15,17-23,25-31,(...),185-191
And a domain with this configuration:
<vcpu placement='static'>1</vcpu>
'virsh vcpupin' will return the following:
$ sudo ./run tools/virsh vcpupin vcpupin_test
VCPU CPU Affinity
----------------------
0 0-191
This is benign by its own, but can make the user believe that all
CPUs from the 0-191 range are eligible for pinning. Which can lead
to situations like this:
$ sudo ./run tools/virsh vcpupin vcpupin_test 0 1
error: Invalid value '1' for 'cpuset.cpus': Invalid argument
This is exarcebated by the fact that 'virsh vcpuinfo' considers only
available host CPUs in the 'CPU Affinity' field:
$ sudo ./run tools/virsh vcpuinfo vcpupin_test
(...)
CPU Affinity: y-------y-------y-------(...)
This patch changes the default bitmap of vcpupin and emulatorpin, in
the case of domains with static vcpu placement, to all available CPUs
instead of all possible CPUs. Aside from making it consistent with
the behavior of 'vcpuinfo', users will now have one less incentive to
try to pin a vcpu in an offline CPU.

The semantics of the backup operation don't strictly require that all

they may not have a previous checkpoint at all (e.g. when the disk
was freshly hotplugged to the vm).
In such cases we can still create a common checkpoint for all of them
and backup differences according to configuration.
This patch adds a per-disk configuration of the checkpoint to do the
incremental backup from via the 'incremental' attribute and allows
perform full backups via the 'backupmode' attribute.
Note that no changes to the qemu driver are necessary to take advantage

any libxml2 functions that allocate memory.
xmlBufferCreate(), for example, might return NULL, and we don't always
check for it. This patch adds checks where it isn't already done.
(NB: Although libxml2 has a provision for changing behavior on OOM (by
calling xmlMemSetup() to change what functions are used to
allocating/freeing memory), we can't use that, since parts of libvirt
code end up in libvirt.so, which is linked and called directly by
applications that may themselves use libxml2 (and may have already set
their own alternate malloc()), e.g. drivers like esx which live totally
in the library rather than a separate process.)

Let us fix the issues with zPCI address validation and auto-generation
on s390.
Currently, there are two issues with handling the ZPCI address
extension. Firstly, when the uid is to be auto-generated with a
specified fid, .i.e.:
...
<address type='pci'>
<zpci fid='0x0000001f'/>
</address>
...
we expect uid='0x0001' (or the next available uid for the domain).
However, we get a parsing error:
$ virsh define zpci.xml
error: XML error: Invalid PCI address uid='0x0000', must be > 0x0000
and <= 0xffff
Secondly, when the uid is specified explicitly with the invalid
numerical value '0x0000', we actually expect the parsing error above.
However, the domain is being defined and the uid value is silently
changed to a valid value.
The first issue is a bug and the second one is undesired behaviour, and
both issues are related to how we (in-band) signal invalid values for
uid and fid. So let's fix the XML parsing to do validation based on what
is actually specified in the XML.
The first issue is also related to the current code behaviour, which
is, if either uid or fid is specified by the user, it is incorrectly
assumed that both uid and fid are specified. This bug is fixed by
identifying when the user specified ZPCI address is incomplete and
auto-generating the missing ZPCI address.

This wasn't a problem until introduction of -blockdev in qemu using of

Now that it works in backing chains and can be moved back and forth
using snapshots/block-commit we need to ensure that the original

To achieve the above semantics we need to store the preferred placement

'passthrough' is Xen-Specific guest configuration option new to Xen 4.13
that enables IOMMU mappings for a guest and hence whether it supports PCI
passthrough. The default is disabled. See the xl.cfg(5) man page and
xen.git commit babde47a3fe for more details.
The default state of disabled prevents hotlugging PCI devices. However,
if the guest configuration contains a PCI passthrough device at time of
creation, libxl will automatically enable 'passthrough' and subsequent
hotplugging of PCI devices will also be possible. It is not possible to
unconditionally enable 'passthrough' since it would introduce a migration
incompatibility due to guest ABI change. Instead, introduce another Xen
hypervisor feature that can be used to enable guest PCI passthrough
<features>
<xen>
<passthrough state='on'/>

To allow finer control over how IOMMU maps to guest P2M table, the
passthrough element also supports a 'mode' attribute with values
restricted to snyc_pt and share_pt, similar to xl.cfg(5) 'passthrough'

virDomainPCIAddressBusSetModel() is called for each PCI controller
when building an address set prior to assiging PCI addresses to
devices.
This patch adds a new argument, allowHotplug, to that function that
can be set to false if we know for certain that a particular
controller won't support hotplug
The most interesting case is in qemuDomainPCIAddressSetCreate(), where
the config of each existing controller is available while building the
address set, so we can appropriately set allowHotplug = false when the
user has "hotplug='off'" in the config of a controller that normally
would support hotplug. In all other cases, it is set to true or false
in accordance with the capability of the controller model.
So far we aren't doing anything with this bus flag in the address set.

New behavior: Don't mess with the bus flags - just directly check if
the AUTOASSIGN flag matches in bus and dev, but only make the check if

When the HOTPLUGGABLE flag was originally added, it was set for all
the PCI controllers that accepted hotplugged devices, and requested
for all devices that were auto-assigned to a controller. While we're
still autoassigning to the same list of controllers, those controllers
may or may not support hotplug, so let's use the flag that fits what

This new flag will be set for any controller that we decide can have
devices assigned to it automatically during PCI device assignment. In
the past PCI_CONNECT_TYPE_HOTPLUGGABLE was used for this purpose, but
that is overloading that flag, and no longer technically correct; what
we *really* want is to auto-assign devices to any pcie-root-port or
pcie-switch-downstream-port regardless of whether or not that
controller happens to have hotplug enabled.
This patch just adds the flag, but doesn't use it at all. Note that
the numbering of all the other flags was changed in order to insert
the new flag near the beginning of the list; that doesn't cause any
problem because the connect flags aren't stored anywhere between runs
of libvirtd.

During startup the udev node device driver impl uses a background thread
to populate the list of devices to avoid blocking the daemon startup
entirely. There is no synchronization to the public APIs, so it is
possible for an application to start calling APIs before the device
initialization is complete.
This was not a problem in the old approach where libvirtd was started
on boot, as initialization would easily complete before any APIs were
called.
With the use of socket activation, however, APIs are invoked from the
very moment the daemon starts. This is easily seen by doing a
'virsh -c nodedev:///system list'
the first time it runs it will only show one or two devices. The second
time it runs it will show all devices. The solution is to introduce a
flag and condition variable for APIs to synchronize against before
returning any data.

During the hypervisor-agnostic validation of network devices, verify
that the interface type is either "network" or "bridge", and that if
there is any <virtualport>, that it doesn't have any type associated
with it.
This needs to be done both for the parse-time validation and for
runtime validation (after a port has been acquired from any associated
network), because an interface with type='network' could have an
actual type at runtime of "hostdev" or "direct", neither of which
support isolated='true' (yet). Likewise, if an interface is
type='network', then at runtime a <virtualport> with a type that
doesn't support isolated='yes' (e.g. "openvswitch", "802.1Qbh" -
currently *none* of the available virtualport types support it)

Similar to the way that the <vlan>, <bandwidth>, and <virtualport>
elements and the trustGuestRxFilters attribute in a <network> (or in
the appropriate <portgroup> element of a <network> can be applied to a
port when it is allocated for a domain's network interface, this patch
checks for a configured value of <port isolated="yes|no"/> in
either the domain <interface> or in the network, setting isolatedPort
in the <networkport> to the first one it finds (the setting from the
domain's <interface> is preferred). This, in turn, is passed back to
the domain when a port is allocated, so that the domain will use that
setting.
(One difference from <vlan>, <bandwidth>, <virtualport>, and
trustGuestRxFilters, is that all of those can be set in a <portgroup>
so that they can be applied only to a subset of interfaces connected
to the network. This didn't really make sense for the isolated setting
due to the way that it's implemented in Linux - the BR_ISOLATED flag
will prevent traffic from passing between two ports that both have
BR_ISOLATED set, but traffic can still go between those ports and
other ports that *don't* have BR_ISOLATED. (It would be nice if all
traffic from a BR_ISOLATED port could be blocked except traffic going
to/from a designated egress port or ports, but instead the entire
feature is implemented as a single flag. Because of this, it's really
only useful if all the ports on a network are isolated, so setting it
for a subset has no practical utility.)

<cpu id='3' socket_id='0' core_id='1' siblings='3'/>

Notice how core_id is repeated within the scope of the same socket_id.
It now reports

<cpu id='0' socket_id='0' die_id='0' core_id='0' siblings='0'/>
<cpu id='1' socket_id='0' die_id='0' core_id='1' siblings='1'/>
