Operating systems use the identifier to name the disks. As the name
suggests the ID should be unique.

Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1208009

Since the WWN influences guest behavior in naming disks we should treat
this as vm ABI.

Use virBitmap helpers that were added after this function.

Change cpumaplen to int and fill it out by this function.

Use virBitmapDataToString instead of constructing the ranges bit
by bit, remove the checking of parameters (that is already done
by the callers).

Let the callers choose the right bitmap, since there's only
one that uses this helper on a matrix-in-an-array.

That function uses domainAttachDeviceFlags

Parallels Cloud Server supports block devices and virtual NIC
live attachment. I implemented that function for block devices so
OpenStack volume attachment is now works.
Signed-off-by: NAlexander Burluka <aburluka@parallels.com>

OpenStack needs disk serial number setup because
nova boot --block-device-mapping command generates that param in
libvirt xml. I took QEMU libvirt driver behavior as a base.
QEMU driver skips inability to set serial and continues work.
So Parallels driver will ignore this param too and let domain
boot.

Do not loop over enum with one value.

This will contain the data required for creating the qemu-img
command line without having access to the volume definition.

Add FromVol at the end. This function will create the qemu-img
command line from volume definitions and check them.

Instead of going through XML nodes in a loop and
having to check if they are duplicate.

For future reuse in the snapshot XML.

This patch adds checks for empty bitmaps right after the calls of
virBitmapParse. These only include spots where set API's are called and
where domain's XML is parsed.
Also, it partially reverts commit 983f5a which added a check for
invalid nodeset "0,^0" into virBitmapParse function. This change broke
the logic, as an empty bitmap should not cause an error.

We only have one formatting function for the features.

Create four smaller blocks of texts instead of one large one.

Simplify the function by leaving out the local copy and checking
return values of virStrToLong.

Request that the number be parsed as decimal, to allow 08
and 09.

Format it with the leading zero, 1.01 and 1.10 are two
different versions.

https://bugzilla.redhat.com/show_bug.cgi?id=1210650

We don't format the default '-1' fields back.

On arm, we probe for virtio-*-pci devices, but use their
virtio-*-device variants.

Set the capabilities based on the -device variants as well,
to make them work with qemus with the PCI devices compiled out.

When pre-creating storage for domains, we need to find corresponding
disk in the XML on the destination (domain XML may differ there, e.g.
disk is accessible under different path). For better debugging, I'm
printing all info I received on a disk. But there was a typo when
printing the disk capacity: "%lluu" instead of "%llu".

The problem with the previous implementation is,
even when qemuMigrationUpdateJobStatus() detects a migration job
has completed, it will do a sleep for 50 ms (which is unnecessary
and only adds up to the VM pause time).

Future IOThread setting patches would copy the code anyway, so create
and generalize the adding of pindef for the vcpu and the pinning of the
thread into their own APIs.

We've been explicitly requesting IPv4 for some reason,
even if there were only IPv6 addresses in the network
definition.

https://bugzilla.redhat.com/show_bug.cgi?id=1192318

Add static virNetDevGetifaddrsAddress to attempt to get the interface
IP address. If getifaddrs is not supported, fall back to
virNetDevGetIPv4AddressIoctl to get the IP address.

This allows IPv6 addresses to be used for <listen type='network>
with device-backed networks.

PCS doesn't store domain config in managed save state file.
It's forbidden to change config for VMs in this state.
It's possible to change config for containers, but after
restoring domain will have that new config, not a config,
which domain had at the moment of virDomainManagedSave.

So we need to handle this case differently from other states.
Let's forbid this operation, if config is changed and if it's
not changed - just do nothing.

Openstack/nova calls virDomainDefineXML on resume with
current domain config, so we can't forbid this operation
in managed save state.

Handle input devices in virDomainDefParseXML properly
in case of parallels containers and VMs.

Parallels containers support only
VIR_DOMAIN_INPUT_BUS_PARALLELS. And if VNC is enabled
we should add implicit mouse and keyboard.

For VMs we should add implicit PS/2 mouse and
keyboard.

BTW, is it worth to refactor code and move
all this code to drivers, to *DomainDefPostParse
functions?

We support VNC for containers to have the same
interface with VMs. At this moment it just renders
linux text console.

Of course we don't pass any physical devices and
don't emulate virtual devices. Our VNC server
renders text from terminal master and sends
input events from VNC client to terminal.

So add special video type VIR_DOMAIN_VIDEO_TYPE_PARALLELS
for these pseudo-devices.
