Recently virtio-9p support was added to bhyve.
On the host side it looks this way:
bhyve .... -s 25:0,virtio-9p,sharename=/path/to/shared/dir
It could also have ",ro" suffix to make share read-only.
In the Linux guest, this share is mounted with:
mount -t 9p sharename /mnt/sharename
In the guest user will see the same permissions and ownership
information for this directory as on the host. No uid/gid remapping is
supported, so those could resolve to wrong user or group names.
The same applies to the other side: chowning/chmodding in the guest will
set specified ownership and permissions on the host.
In libvirt domain XML it's modeled using the 'filesystem' element:
<filesystem type='mount'>
<source dir='/path/to/shared/dir'/>
<target dir='sharename'/>
</filesystem>
Optional 'readonly' sub-element enables read-only mode.

Support modeling of the 'isa' controller for bhyve. User can manually
define any PCI slot for the 'isa' controller, including PCI slot 1,
but other devices are not allowed to use this address.
When domain configuration requires the 'isa' controller to be present,
automatically add it on domain post-parse stage.
Now, as this controller is always available when needed, it's not
necessary to implicitly add it to the bhyve command line, so remove
bhyveBuildLPCArgStr().
Also, make bhyveDomainDefNeedsISAController() static as it's no longer
used outside of bhyve_domain.c.
As more than one ISA controller is not supported by bhyve,
and multiple controllers with the same index are forbidden,
so forbid ISA controllers with non-zero index for bhyve.

In most cases this eliminates one or more calls to
virBufferClearAndReset(), but even when it doesn't it's better because:
1) it makes the code more consistent, making it more likely that new
contributors who are "learning by example" will to the right thing.
2) it protects against future modifications that might have otherwise
needed to add a virBufferClearAndReset()
3) Currently some functions don't call virBufferClearAndReset() only
because they're relying on some subordinate function to call it for
them (e.g. bhyveConnectGetSysinfo() in this patch relies on
virSysinfoFormat() to clear out the buffer when there is an
error). I think this is sloppy behavior, and that the toplevel
function that defines and initializes the buffer should be the
function clearing it at the end.

Recently CPU hardware vendors have started to support a new structure
inside the CPU package topology known as a "die". Thus the hierarchy

Along with video and VNC support, bhyve has introduced USB tablet

as a device on an XHCI controller.
At present, tablet is the only supported device on the XHCI controller

single XHCI controller with a single tablet device.
In detail, this commit:
- Introduces a new capability bit for XHCI support in bhyve

virNetDevTapCreateInBridgePort() has always set the new tap device to
the current MTU of the bridge it's being attached to. There is one
case where we will want to set the new tap device to a different
(usually larger) MTU - if that's done with the very first device added
to the bridge, the bridge's MTU will be set to the device's MTU. This
patch allows for that possibility by adding "int mtu" to the arg list
for virNetDevTapCreateInBridgePort(), but all callers are sending -1,
so it doesn't yet have any effect.
Since the requested MTU isn't necessarily what is used in the end (for
example, if there is no MTU requested, the tap device will be set to
the current MTU of the bridge), and the hypervisor may want to know
the actual MTU used, we also return the actual MTU to the caller (if
actualMTU is non-NULL).
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.
We have couple of functions that operate over NULL terminated
lits of strings. However, our naming sucks:
virStringJoin
virStringFreeList
virStringFreeListCount
