We shouldn't be duplicating libvirt documentation here. If someone
needs <virtualport> config, they are likely working backwards from
working XML and trying to figure out the command line. Drop most
of the details
Sort out the memory property naming ambiguity on the command line.
* memory -> currentMemory
* maxmemory -> memory
* hotplugmemorymax -> maxMemory
* hotplugmemoryslots -> maxMemory.slots
To maintain back compat, we need to do some funky handling with
memory and maxmemory values. Basically if currentMemory is specfied,
we interpret them as new style, otherwise preserve the old behavior.
This will allow users to override the default behavior of virt-install
which copies CPU security features available on the host to the guest
XML if specific CPU model is configured.

Add kernel= and initrd= --location suboptions. These can be
used to override the default kernel/initrd and specify new
paths, relative to LOCATION.
For example, if you have an ISO that libosinfo doesn't know
about called my-unknown.iso, with a kernel at 'kernel/fookernel'
and initrd at +'kernel/fooinitrd', you can make this work with:
--location my-unknown.iso,kernel=kernel/fookernel,initrd=kernel/fooinitrd
We're not doing anything with it yet, but having the
parser accept it means we can write tests and see how
their output changes once we wire it up in earnest.

The --os-variant option doesn't quite fit perfectly into
its current "Installation method" group, plus we want to
add the same option to virt-xml which can't have that
group for obvious reasons.

Add vcpupin support to virt-install so that it can create guest
domains with statically allocated vcpu pinning towards a given cpuset.
Syntax: to pin vcpu=0 to cpuset="1,3" and vcpu=1 to cpuset=2
--cputune vcpupin0.vcpu=0,vcpupin0.cpuset=1,3,vcpupin1.vcpu=1,vcpupin1.cpuset=2
generates below XML description for the guest domain.
<cputune>
<vcpupin vcpu="0" cpuset="1,3"/>
<vcpupin vcpu="1" cpuset="2"/>
</cputune>

libvirt supports guest CPU cache by commit df13c0b, So add this feature
to virt-install to configure cpu L3 cache mode.
Currently, The valid values are 'passthrough', 'emulate' or 'disable'.
say:
--cpu host-passthrough,cache.mode=passthrough
or
--cpu $CPU,cache.mode=emulate,cache.level=3
or
--cpu $CPU,cache.mode=disable

There are multiple models of the panic device, the address type is only
one and is valid only for "isa" model.
To not break the virt-install/virt-xml the command line parser needs to
be updated. Before this patch there was only one parameter that
configured the "iobase". Now the first parameter configures a model
but to keep it backward compatible it follows these rules:
1. there is only one parameter and it matches known model:
--panic isa
<panic model='isa'>
<address iobase='0x505' type='isa'/>
</panic>
2. there is only one parameter and it doesn't match any model:
--panic 0x505
<panic model='isa'>
<address iobase='0x505' type='isa'/>
</panic>
3. there are two parameters:
--panic isa,iobase=0x505
<panic model='isa'>
<address iobase='0x505' type='isa'/>
</panic>

This element controls hot(un)plugable memory for the guest in
addition to the initial memory configured by <memory> element.
One has to configure <maxMemory> and guest numa nodes using <numa>
element to enable hot(un)plug of memory modules.

We forgot to mention --qemu-commandline in virt-xml.pod.
Also added an example copied from Cole's blog.

If this flag is specified, --import|--boot will create a transient
libvirt domain, ie. one which goes away when the guest shuts down or
the host is rebooted.
(crobinso: some tweaks and tests)
This is the new style socket support, where we request libvirt to
allocate a socket path for us. Plus this is the only way to enable
socket support for type=spice
This exposes every device <address> option, for each device
cli option. So --disk, --network, --video, etc.
Fill out a few more address XML bits as well
Add a special listen value to disable any extra display server listening
socket. This is necessary now that qemu prevents starting a spice+virgl
VM with listening sockets (until spice allows remoting with virgl).

Add a --graphics option to enable accelarated rendering using
OpenGl. This is used only by Spice (and for local only guests atm).

So we can call clear() on a Guest owned VirtualDisk, and it actually
does the correct thing. This allows us to enable clearxml= cli option
for most devices.
Commit 549c93be fixed a man page to make --sparse documentation
consistent, but it forget to updated also the next paragraph.

It annoys me that all the other CLI options map to the libvirt XML name,
except this one. Of course, keep the old option around for back compat,
just give precendence to the new option.
This streamlines virt-manager and virt-install implementations, requiring
installer.distro_detect to be called if we want distro detection. As
a side effect, we now get CDROM detection for free.
