https://bugzilla.redhat.com/show_bug.cgi?id=1076708
https://bugzilla.redhat.com/show_bug.cgi?id=890606
New in v3:
* preserve the behavior of honoring the controller if a partial address is specified:
<address type='virtio-serial' controller='2'/>
* automatically add a controller if we're out of free ports
and add a test for it
Ján Tomko (6):
Add test for virtio serial port assignment
Add functions to track virtio-serial addresses
Allocate virtio-serial addresses when starting a domain
Expand the address set when attaching a virtio-serial controller
Assign an address when hotplugging a virtio-serial device
Auto add virtio-serial controllers

Create a sorted array of virtio-serial controllers.
Each of the elements contains the controller index
and a bitmap of available ports.
Buses are not tracked, because they aren't supported by QEMU.

New subject: [libvirt] [PATCHv3 3/6] Allocate virtio-serial addresses when starting a domain
Instead of always using controller 0 and incrementing port number,
respect the maximum port numbers of controllers and use all of them.
Ports for virtio consoles are quietly reserved, but not formatted
(neither in XML nor on QEMU command line).
Also rejects duplicate virtio-serial addresses.
https://bugzilla.redhat.com/show_bug.cgi?id=890606
https://bugzilla.redhat.com/show_bug.cgi?id=1076708
Test changes:
* virtio-auto.args
Filling out the port when just the controller is specified.
switched from using
maxport + 1
to:
first free port on the controller
* virtio-autoassign.args
Filling out the address when no <address> is specified.
Started using all the controllers instead of 0, also discards
the bus value.
* xml -> xml output of virtio-auto
The port assignment is no longer done as a part of XML parsing,
so the unspecified values stay 0.

https://bugzilla.redhat.com/show_bug.cgi?id=890606
New in v3:
* preserve the behavior of honoring the controller if a partial address is specified:
<address type='virtio-serial' controller='2'/>
* automatically add a controller if we're out of free ports
and add a test for it
Ján Tomko (6):
Add test for virtio serial port assignment
Add functions to track virtio-serial addresses
Allocate virtio-serial addresses when starting a domain
Expand the address set when attaching a virtio-serial controller
Assign an address when hotplugging a virtio-serial device
Auto add virtio-serial controllers
