With multi volume boxes, need to ensure that disk settings such as the
device assigned are resolved dynamically once it has been established
which devices have already been assigned to the box volumes on either
initial creation or subsequent boots.
Otherwise users are forced to always explicitly define the device for
additional storage instead of having it be automatically assigned the
next available device.
Consequently previous changes have broken the ability for machines
with additional storage to be halted and restarted correctly.
Include an integration test that for additional storage checks that the
machine can be stopped and started again.
Fixes: #1490
When assigning a pci passthrough device, the domain, bus, slot and
function parameters pertain to the host device address. Add guest_
flavours of these to allow setting the address of the device in the
guest as well.
Fixes: #1475
Libvirt did already change the current 9216kb
to 16384kb when starting a domain so in practice this is a no-op.
The libvirt default was changed in 2014 in 81ba2298b2
When cpu mode was set to host-passthrough the template would skip
setting all other settings for the cpu, while it appears from the
documentation that it supports use of feature elements, and testing
confirms that it also supports the topology element.

To make it easier to see when the XML generated has deviated from
expected, tidy up the emitted XML to use a more consistent formatting
that would be inline with what would be expected to be output by virsh
directly.
Re-enable handling of the disk_device domain volume setting to ensure it
can be overridden from the default of vda to a value chosen.
Provide a disk resolver to resolve devices after the box has been downloaded
so that initial devices can be correctly allocated and avoid conflicts with
additional disks added that would otherwise get assigned the same device.
Removes hack for destroy domain when more than one disk, as now devices
in the config are only present if provided by the configuration.
Fixes: #1353
When enabling video_accel3d, as graphics_gl is typically required, will
by default set it to true unless explicitly set to false.
Enabling these should result in a significant performance improvement
for any VM where the desktop is being used.

time messages to a log file.

It is more reliable to identify disk and network devices by use of
aliases, in addition to being able to establish in the absence of
information the purpose of such devices.
There is a possibility that in some cases this will also resolve issues
where the same device attach issued twice with the same details will
fail due to the second request not appearing to be honoured.
Additionally when destroying domains, may not have the relevant details
on how many disks are provided by the box, for those that support
multiple disks. Being able to traverse the domain XML and destroy the
appropriate volumes based on aliases names will remove the need to have
predictable device identifiers during the destroy and allow for an
improved resolver.

Although it is possible to attach additional images (disk or cdrom) the
cdrom functionality doesn't allow setting the :type - it defaults to
'raw' since vagrant-libvirt is assuming cdrom images are in ISO9660
format.
This assumption breaks down when using vagrant-mutate to convert a box
with multiple storage devices. A common situation is the Ubuntu boxes
built for VirtualBox that contain a cloud-init ISO9660 image with
user-data. vagrant-mutate converts the image to qcow* format (not
ISO9660) in order to not have to deal with what is inside.
This means the resulting libvirt domain needs to be told the type is
'qcow2' in order for the guest to see it as an ISO9660 image.
This patch adds the required option along with a sensible default.
Adds support for a new multi disk box format and handling to upload the
multiple disks to the storage pool.
New format is:
{
'disks': [
{
'name': 'disk1.img',
'virtual_size': 10,
'format': 'qcow2'
},
{
'name': 'disk2.img',
'virtual_size': 15,
'format': 'qcow2'
},
{
'name': 'disk3.img',
}
],
'provider': 'libvirt',
'format': 'qcow2'
}
It is expected to remove format from being set at the top level when
using the new format, with the assuming that qcow2 should be the default
format, and other formats should be permitted to be specified as needed.
Includes tests for handling the box images and creation of domain
volumes. Additionally includes an integration test to ensure a box with
2 disks will work as expected.
Partially fixes: #602
Adds disk driver options: io, copy_on_read, discard and detect_zeroes
for both the primary vm disk and additional disks.
Minor refactor of existing volume_cache to deprecate and replace with a
single call to disk_driver that contains all of the options. Usage of
the volume_cache option will now result in a message to ui that it has
been replaced, as well as a warning that it is ignored if disk_driveris
set.
The old option volume_cache is only used if disk_driver is not present
(even if :cache is not set - in that case, the hypervisor default is
always used).
Resolves#998
Allow configuration of various memballoon-related settings. It was
discovered that it may be needed to be able to control the memballoon's
PCI slot/bus location in order to prevent it from conflicting with
other explicit PCI location assignments. For example when configuring
the management network NIC to go to slot 0x05, libvirt would try to put
the memballoon there as well and resulting in a fatal error.
Qemu has supported tpm 2 and the ability to start swtpm. Additionally
it expands the tests for the tpm configuration to ensure that only when
the options cause a change to the domain XML will the domain be updated
on a subsequent start. This change just allows passing through the
necessary config.
Vagrant.configure("2") do |config|
config.vm.provider :libvirt do |libvirt|
libvirt.tpm_model = "tpm-crb"
libvirt.tpm_type = "emulator"
libvirt.tpm_version = "2.0"
end
end
closes#965
Make it easier to tweak some qemu options by allowing passthru of
command line environment variables.
- Also cleans up weird variable indirection used for qemu commandline args
variable through `qargs` in various constructors.
- Addresses some functionality discussed in #776.
* Add USB controller configuration
* Update README with USB controller configuration info
* Rename USB controller parameter to usb_controller
* Code style fixup
Some UEFI firmwares may want to use a non-volatile memory to store
variables.
This requires to specify loader and nvram to use UEFI boot in QEMU.
Specifying loader and nvram at the same time will set loader to
type 'pflash' instead of 'rom'.
If loader is used without nvram option type will remain 'rom'.
Further information can be found at libvirt documentation:

Changes in names of data being passed through from the config object to
the CreateDomain action means that to test the domain xml template,
need to add an additional variable of qargs when testing.
Add basic spec tests for the domain template to test rendering through
simple wrapping of a config object to provide values for class instance
variables used by the template as it mostly mirrors those required.
