Recently, bhyve started supporting specifying guest CPU topology.
It looks this way:
bhyve -c cpus=C,sockets=S,cores=C,threads=T ...
The old behaviour was bhyve -c C, where C is a number of vCPUs, is
still supported.
So if we have CPU topology in the domain XML, use the new syntax,
otherwise keep the old behaviour.
Also, document this feature in the bhyve driver page.

This flag is only used for tests. Let's instead overload bind syscall
in mocks where it is not done yet.

Range check in virPortAllocatorSetUsed is not useful anymore
when we manage ports for entire unsigned short range values.

Host tcp4/tcp6 ports is a global resource thus we need to make
port accounting also global or we have issues described in [1] when
port allocator ranges of different instances are overlapped (which
is by default for qemu for example).
Let's have only one global port allocator object that take care
of the entire ports range (0 - 65535) and introduce port range object
for clients to specify desired auto allocation band.

Right-aligning backslashes when defining macros or using complex
commands in Makefiles looks cute, but as soon as any changes is
required to the code you end up with either distractingly broken
alignment or unnecessarily big diffs where most of the changes
are just pushing all backslashes a few characters to one side.

Add support for vgaconf driver configuration. In domain xml it looks like
this:
<video>
<driver vgaconf='io|on|off'>
<model .../>
</video>
It was added with bhyve gop video in mind to allow users control how the
video device is exposed to the guest, specifically, how VGA I/O is
handled.
One can refer to the bhyve manual page to get more detailed description
of the possible VGA configuration options:
https://www.freebsd.org/cgi/man.cgi?query=bhyve&manpath=FreeBSD+12-current
The relevant part could be found using the 'vgaconf' keyword.
Also, add some tests for this new feature.

Along with video and VNC support, bhyve has introduced USB tablet
support as an input device. This tablet is exposed to a guest
as a device on an XHCI controller.
At present, tablet is the only supported device on the XHCI controller
in bhyve, so to make things simple, it's allowed to only have a
single XHCI controller with a single tablet device.
In detail, this commit:
- Introduces a new capability bit for XHCI support in bhyve
- Adds an XHCI controller and tabled support with 1:1 mapping
between them
- Adds a couple of unit tests
Recently e1000 NIC support was added to bhyve; implement that in
the bhyve driver:
- Add capability check by analyzing output of the 'bhyve -s 0,e1000'
command
- Modify bhyveBuildNetArgStr() to support e1000 and also pass
virConnectPtr so it could call bhyveDriverGetCaps() to check if this
NIC is supported
- Modify command parsing code to add support for e1000 and adjust tests
- Add net-e1000 test
Like it usually happens, I fixed one thing and broke another:
in 803966c76 address allocation was fixed for SATA disks, but
broke that for virtio disks, because it dropped disk address
assignment completely. It's not needed for SATA disks anymore,
but still needed for the virtio ones.
Bring that back and add a couple of tests to make sure it won't
happen again.
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.
* virNetDevTapCreateInBridgePort() mock: free '*ifname' before
strdupping a hardoded value to it
* testCompareXMLToArgvFiles(): unref 'conn' object in cleanup
* testCompareXMLToArgvHelper(): free 'ldargs' and 'dmargs' in
cleanup
We want to pass the proper opaque pointer instead of NULL to
virDomainDefParse and subsequently virDomainDefParseNode too.

Make bhyveload respect boot order as specified by os.boot section of the
domain XML or by "boot order" for specific devices. As bhyve does not
support a real boot order specification right now, it's just about
choosing a single device to boot from.
Bhyve as of r279225 (FreeBSD -CURRENT) or r284894 (FreeBSD 10-STABLE)
supports using UTC time offset via the '-u' argument to bhyve(8). By
default it's still using localtime.
Make the bhyve driver use UTC clock if it's requested by specifying
<clock offset='utc'> in domain XML and if the bhyve(8) binary supports
the '-u' flag.
gcc5 reports an error like this:
bhyvexml2argvtest.c: In function 'testCompareXMLToArgvFiles':
bhyvexml2argvtest.c:24:18: error: variable 'vm' set but not used

Fix by dropping this variable.
Commit 835cf84 dropped expectedVirtTypes argument for
virDomainDefParse*() functions, however bhyve tests still try to pass
that to virDomainDefParseFile(), therefore build fails.
Fix build by fixing virDomainDefParseFile() usage.
The virDomainDefParse* and virDomainDefFormat* methods both
accept the VIR_DOMAIN_XML_* flags defined in the public API,
along with a set of other VIR_DOMAIN_XML_INTERNAL_* flags
defined in domain_conf.c.
This is seriously confusing & error prone for a number of
reasons:
- VIR_DOMAIN_XML_SECURE, VIR_DOMAIN_XML_MIGRATABLE and
VIR_DOMAIN_XML_UPDATE_CPU are only relevant for the
formatting operation
- Some of the VIR_DOMAIN_XML_INTERNAL_* flags only apply
to parse or to format, but not both.
This patch cleanly separates out the flags. There are two
distint VIR_DOMAIN_DEF_PARSE_* and VIR_DOMAIN_DEF_FORMAT_*
flags that are used by the corresponding methods. The
VIR_DOMAIN_XML_* flags received via public API calls must
be converted to the VIR_DOMAIN_DEF_FORMAT_* flags where
needed.
The various calls to virDomainDefParse which hardcoded the
use of the VIR_DOMAIN_XML_INACTIVE flag change to use the
VIR_DOMAIN_DEF_PARSE_INACTIVE flag.
Rather than just picking the first CD (or failing that, HDD) we come
across, if the user has picked a boot device ordering with <boot
order=''>, respect that (and just try to boot the lowest-index device).
Adds two sets of tests to bhyve2xmlargv; 'grub-bootorder' shows that we
pick a user-specified device over the first device in the domain;
'grub-bootorder2' shows that we pick the first (lowest index) device.
Update bhyveBuildDiskArgStr to support volumes:
- Make virBhyveProcessBuildBhyveCmd and
virBhyveProcessBuildLoadCmd take virConnectPtr as the
first argument instead of bhyveConnPtr as virConnectPtr is
needed for virStorageTranslateDiskSourcePool,
- Add virStorageTranslateDiskSourcePool call to
virBhyveProcessBuildBhyveCmd and
virBhyveProcessBuildLoadCmd,
- Allow disks of type VIR_STORAGE_TYPE_VOLUME
Add support for CDROM devices for bhyve driver using
bhyve(8)'s 'ahci-cd' device type.
As bhyve currently does not support media insertion at runtime,
disallow to start a domain with an empty source path for cdrom
devices.
At this point unittest covers 4 basic cases:
- minimal working XML for bhyve
- same as above, but with virtio disk
- ACPI and APIC args test
- MAC address test
