As bhyve for a long time didn't have a notion of the explicit SATA
controller and created a controller for each drive, the bhyve driver
in libvirt acted in a similar way and didn't care about the SATA
controllers and assigned PCI addresses to drives directly, as
the generated command will look like this anyway:
2:0,ahci-hd,somedisk.img
This no longer makes sense because:
1. After commit c07d1c1c4f it's not possible to assign
PCI addresses to disks
2. Bhyve now supports multiple disk drives for a controller,
so it's going away from 1:1 controller:disk mapping, so
the controller object starts to make more sense now
So, this patch does the following:
- Assign PCI address to SATA controllers (previously we didn't do this)
- Assign disk addresses instead of PCI addresses for disks. Now, when
building a bhyve command, we take PCI address not from the disk
itself but from its controller
- Assign addresses at XML parsing time using the
assignAddressesCallback. This is done mainly for being able to
verify address allocation via xml2xml tests
- Adjust existing bhyvexml2{xml,argv} tests to chase the new
address allocation
This patch is largely based on work of Fabian Freyer.
Add virBhyveDriverCreateXMLConf, a simple wrapper around
virDomainXMLOptionNew that makes it easier to pass bhyveConnPtr
as a private data for parser. It will be used later for device
address allocation at parsing time.
Update consumers to use it instead of direct calls to
virDomainXMLOptionNew.
As we now have proper callbacks connected for the tests, update
test files accordingly to include the automatically generated
PCI root controller.
Introduce a BHYVE_CAP_AHCI32SLOT capability that shows
if 32 devices per SATA controller are supported, and
a bhyveProbeCapsAHCI32Slot function that probes it.
Because this is invalid xml for containers. This patch almost
reverts 7eda8369, but still skips converting vz sdk bootorder
for containers to libvirt bootorder because we use boot order
in containers for quite different purpurse.

For example when both total_bytes_sec and total_bytes_sec_max are set,
but the former gets cleaned due to new call setting, let's say,
read_bytes_sec, we end up with this weird message for the command:
$ virsh blkdeviotune fedora vda --read-bytes-sec 3000
error: Unable to change block I/O throttle
error: unsupported configuration: value 'total_bytes_sec_max' cannot be set if 'total_bytes_sec' is not set
So let's make it more descriptive. This is how it looks after the change:
$ virsh blkdeviotune fedora vda --read-bytes-sec 3000
error: Unable to change block I/O throttle
error: unsupported configuration: cannot reset 'total_bytes_sec' when 'total_bytes_sec_max' is set

All options started with underscores, but we switched them to dashes
later on, making the style consistent. The latest addition, however,
did not respect that, so let's change that as well. It is tempting to
just change the name instead of adding alias, especially since nobody
ever used it, which we know thanks to the fact that it didn't work.

We were setting it based on whether it was supported and that lead to

The 'fs' backend m4 code was copied, but one of the condition were not
changed which resulted into:
configure: Gluster: yes
configure: ZFS: yes
configure: Virtuozzo storage: check
Make the code turn on the virtuozzo driver automatically if the tools
are found.
The issue is that if this graphics definition is provided:
<graphics type='vnc' port='0'/>
it's parsed as:
<graphics type='vnc' autoport='no'>
<listen type='address'/>
</graphics>
but if the resulting XML is parsed again the output is:
<graphics type='vnc' port='-1' autoport='yes'>
<listen type='address'/>
</graphics>
and this should not happen. The XML have to always remain the same
after it was already parsed by libvirt.

This commit is similar to commit 0977ada8.The virsh manpage
lists options --uuid and --name as mutually exclusive if

Commit id '5f07c3c07' broke the freebsd build in the libvirt CI test
environment because the UMOUNT was not defined unless WITH_STORAGE_FS
is defined.
So remove the virStorageBackendUmountLocal from storage_util.c,h and
restore the code back in the storage_backend_fs.c and _vstorage.c
modules.

Move all the volume functions to storage_util to create local/common helpers
using the same naming syntax as the existing upload, download, and wipe
virStorageBackend*Local API's.
In the process of doing so, found more API's that can now become local

The current logic around configuring timers in libxl based on
virDomainDef object is a bit brain dead. Unsupported timers are
silently ignored and tsc is only recognized if it is the first
timer specified.
Change the logic to reject unsupported timers and honor the tsc
timer regardless of its order when multiple timers are specified.
It is destructive to attempt reset on a pci- or cardbus-bridge, the
