4b75237fe6 domain_conf: introduce virDomainGraphicsListenAppendAddress
This effectively removes virDomainGraphicsListenSetAddress which was
used only to change the address of listen structure and possible change
the listen type.  The new function will auto-expand the listens array
and append a new listen.

The old function was used on pre-allocated array of listens and in most
cases it only "add" a new listen.  The two remaining uses can access the
listen structure directly.

112ae48192 conf: virDomainDiskDefIotuneParse: simplify parsing
Since the structure was pre-initialized to 0 we don't need to set every
single member to 0 if it's not present in the XML. Additionally if we
put the name of the field into the error message the code can be
simplified using a macro to parse the members.

6d8b6d2847 conf: also mark the implicit video as primary
Commit 119cd06 started setting the primary bool for the first

However this was done before the addition of the implicit device.
This broke startup of transient qemu domains with no <video>:

Move this default to virDomainDefPostParseInternal,

17a94ba70f nodedev: Fix parsing of generated XMLs
Commit d77ffb6876 added not only reporting of the PCI header type, but
also parsing of that information.  However, because there was no parsing
done for the other sub-PCI capabilities, if there was any other
capability then a valid header type name (like phys_function or
virt_functions) the parsing would fail.  This prevented passing node
device XMLs that we generated into our own functions when dealing with,
e.g. with SRIOV cards.

Instead of reworking the whole parsing, just fix this one occurence and
remove a test for it for the time being.  Future patches will deal with
the rest.

7068b56c85 conf: qemu: Add support for more HyperV Enlightenment features
This patch adds support for "vpindex", "runtime", "synic",
"stimer", and "vendor_id" features available in qemu 2.5+.

- When Hyper-V "vpindex" is on, guest can use MSR HV_X64_MSR_VP_INDEX
to get virtual processor ID.

- Hyper-V "runtime" enlightement feature allows to use MSR
HV_X64_MSR_VP_RUNTIME to get the time the virtual processor consumes
running guest code, as well as the time the hypervisor spends running
code on behalf of that guest.

- Hyper-V "synic" stands for Synthetic Interrupt Controller, which is
lapic extension controlled via MSRs.

- Hyper-V "stimer" switches on Hyper-V SynIC timers MSR's support.
Guest can setup and use fired by host events (SynIC interrupt and
appropriate timer expiration message) as guest clock events

- Hyper-V "reset" allows guest to reset VM.

- Hyper-V "vendor_id" exposes hypervisor vendor id to guest.

9d243e0895 conf: add 'state' attribute to <hap> feature
Most hypervisors use Hardware Assisted Paging by default and don't
require specifying the feature in domain conf. But some hypervisors
support disabling HAP on a per-domain basis. To enable HAP by default
yet provide a knob to disable it, extend the <hap> feature with a
'state=on|off' attribute, similar to <pvspinlock> and <vmport> features.

In the absence of <hap>, the hypervisor default (on) is used. <hap>
without the state attribute would be the same as <hap state='on'/> for
backwards compatibility. And of course <hap state='off'/> disables hap.

5a9cbc6265 Add event and state details for post-copy
VIR_DOMAIN_EVENT_SUSPENDED_POSTCOPY and VIR_DOMAIN_PAUSED_POSTCOPY are
used on the source host once migration enters post-copy mode (which
means the domain gets paused on the source. After the destination host
takes over the execution of the domain, its virtual CPUs are resumed and
the domain enters VIR_DOMAIN_RUNNING_POSTCOPY state and
VIR_DOMAIN_EVENT_RESUMED_POSTCOPY event is emitted.

In case migration fails during post-copy mode and none of the hosts have
complete state of the domain, both domains will remain paused with
VIR_DOMAIN_PAUSED_POSTCOPY_FAILED reason and an upper layer may decide
what to do.
