4abfb330ea domain_conf: move all ChrSource checks to domain_validate.c
Next patch will move a validation to virDomainSmartcardDefValidate(),
but this function can't be moved alone to domain_validate.c without
making virDomainChrSourceDefValidate(), from domain_conf.c, public.

Given that the idea is to eventually move all validations to domain_validate.c
anyways, let's move all ChrSource related validations in a single punch.

b9e56a0fa0 domain_validate.c: rename virSecurityDeviceLabelDefValidateXML()
The function isn't doing XML validation of any sort. Rename it to
be compatible with its actual use.

While we're at it, change the VIR_ERR_XML_ERROR error being thrown
in the function to VIR_ERR_CONFIG_UNSUPPORTED.

98bc393579 domain_conf: move vendor, product and tray checks to domain_validate.c
The 'tray' check isn't a XML parse specific code and can be pushed
to the validate callback, in virDomainDiskDefValidate().

'vendor' and 'product' string sizes are already checked by the
domaincommon.rng schema, but can be of use in the validate callback
since not all scenarios will go through the XML parsing.

654e106397 domain_conf: move virDomainDiskDefValidate() to domain_validate.c
Next patch will add more validations to the function. Let's move
it beforehand to domain_validate.c.

virSecurityDeviceLabelDefValidateXML() is still used inside
domain_conf.c, so make it public for now until its current
caller (virDomainChrSourceDefValidate()) is also moved to
domain_validate.c.

This check isn't exclusive to XML parsing. Let's move it to

'video-multiple-primaries' was added to test this failure case.

7ad9162961 domain_conf: move boot timeouts check to domain_validate.c
This patch creates a new function, virDomainDefBootValidate(), to host
the validation of boot menu timeout and rebootTimeout outside of parse
time. The checks in virDomainDefParseBootXML() were changed to throw
VIR_ERR_XML_ERROR in case of parse error of those values.

In an attempt to alleviate the amount of code being stacked inside
domain_conf.c, let's put this new function in a new domain_validate.c
file that will be used to place these validations.

e556b2c616 Revert "domain_conf.c: auto-align pSeries NVDIMM in virDomainMemoryDefPostParse()"
The code to align ppc64 NVDIMMs on post parse was introduced in
commit d3f3c2c97f. That commit failed to realize that we
can't align memory unconditionally. As of commit c7d7ba85a6
("qemu: command: Align memory sizes only on fresh starts"),
all memory alignment should be executed only when we're not
migrating or in a snapshot.

This revert does not break any guests in the wild, given that
ppc64 NVDIMMs are still being aligned in qemuDomainAlignMemorySizes().

Next patch will introduce a mechanism where we can have post
parse NVDIMM alignment for pSeries without breaking the
intended design, as defined by c7d7ba85a6.

This reverts commit d3f3c2c97f.

e43fa9c932 domain_conf: Fix virDomainMemoryModel type
The virDomainMemoryModel structure has a @type member which is
really type of virDomainMemoryModel but we store it as int
because the virDomainMemoryModelTypeFromString() call stores its
retval right into it. Then, to have compiler do compile time
check for us, every switch() typecasts the @type. This is
needlessly verbose because the parses already has @val - a
variable to store temporary values. Switch @type in the struct to
virDomainMemoryModel and drop all typecasts.

6e4fbc97ff conf: Require nvdimm path in validate step
Our code expects that a nvdimm has a path defined always. And the
parser does check for that. Well, not fully - only when parsing
<source/> (which is an optional element). So if the element is
not in the XML then the check is not performed and the assumption
is broken. Verify in the memory def validator that a path was
set.

3fc4412c6f qemu: support kvm-poll-control performance hint

This patch adds a new KVM feature 'poll-control' to set this performance

To enable this hint and have libvirt add "-cpu host,kvm-poll-control=on"
to the QEMU command line, the following XML code needs to be added to the
guest's domain description:
