Previous PR added tests but missed that the disk controller was not
being set correctly in the create domain action by default.
Update config documentation to include option.
For better performance allows enabling the virtio-scsi model on the
scsi controller in VM's.
Additionally supports inferring use of virtio-scsi model from disk
device or bus, and similarly infer the correct values for these
based on device or bus.
Currently one controller per 7 domain volume disks is created, this
follows virt-manager's behaviour, and is assumed a reasonable default.
However note that virtio-scsi should be capable of allowing many more
disks to be assigned per controller than this. It is presumed that the
source of the number 7 is allowing for 8 devices per controller
including the host adapter, which therefore allows for 7. Hardware SCSI
controllers typically supported 16 addressable devices including the
adapter providing for a 15 disk limit. Whether this is necessary is not
yet clear.

If a box is added directly without a version, vagrant will default set
it to 0. When this occurs it is necessary to ensure use of mtime to
distinguish when the disk image in the box was last updated to allow
replacement of the box to trigger a fresh upload.
Fixes: #1382
Ensure that when no box is defined for a pxe install, that the domain
name is only populated for subsequent boots and if it is already
provided by a create action, skip attempting to retrieve from a
non-existing domain XML.
Fixes: #1508
Vagrant newer than 2.2.11 reworked how the after hook definition
functions requiring it to be called in a different way to ensure it is
possible to hook the box remove action to perform the expected local
action.
Add a compatibility function to ensure that the plugin works with both
mechanisms and some simple tests to ensure that with the unit tests
validated against the older vagrant versions that it confirms the action
will be called as expected.
As part of fixing the call of the remove_libvirt_image action, ensure it
only executes when the box removed is a libvirt one and ignores all
others.
Fixes: #1196
Detect when the device provided for connecting the VM to a public
network via the host does not exist and attempt to provide a useful
error message to give end users a hint of how to correct.
Fixes: #1477
Calling undefine on a domain and recreating it can result in some edge
case errors where if the current capabilities of libvirt have been
reduced, it may not be possible to restore the old definition.
Instead switch to calling `domain_define` with the new definition and
check that the resulting libvirt domain definition has been updated in
the expected manner, otherwise report an error to the user.

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 removing networks, skip calling destroy to deactivate the network
if it is not currently active. This avoids errors when the host has been
rebooted and vagrant machines are removed as the networks are typically
not automatically started.
The loader tag is required when nvram is being enabled. Ensure it is
marked as a requirement of validation and also support it's
configuration during the start domain action.
Handle enabling and disabling of NVRAM during start domain.
This patch contains latent support for upstream PR fog-libvirt#102 to support destroy
with NVRAM enabled once that is merged.
Fixes#1027.
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
Using `autoload` fairly consistently results in 'constant not defined'
errors for each of HandleBox, SyncedFolders, WaitForCommunicator
when using ruby 3.1. Presumably there's some sort of race condition.
Explicitly using `require` for these three makes the problem go away.
It might be a bit ugly to have those `require` lines right at the
point where those symbols are used, vs. the neat `autoload` section
at the top of the file, but I'm not sure how better to structure this.
Suggestions most welcome :-)

Provisioning is executed on the out-call action, so it should be added
the call start before the configuration of the network interfaces is
scheduled via a guest capability as it is also executed out the out call
to allow the first part to be performed before the VM is booted and the
latter to be done after it is running.
Fixes: #1479
Avoid crash caused by power management suspension where fog fails to translate domain state pmsuspended.
Changed the driver.state() function so that it does not crash on undefined domain state. Just return nil :unknown instead.
Added unittests and made existing more general.

Switch to the command as an array format when passing the port
forwarding ssh command to spawn to switch to execution of the ssh
process directly instead of being executed by the default shell.
Fixes: #1467
Facilitate disabling serial devices by allowing for the configuration to
explicitly set serials to an empty array and ignoring adding the default
serial if this is the case.
Autoloading interaction with threads can cause issues. Follow the best
practice of performing the autoloading early in the hope that this
avoids the issue with a symbol not being fully defined before
another thread attempts to use the symbol in the same file.

Trying to create a routed network with just ipv6 fails with:
Error occurred while creating new network: Call to virNetworkDefineXML failed: XML error: Missing required address attribute in network 'test'.
Since an ipv4 address should be optional for this scenario, make it so.
This makes the following configuration work:
config.vm.network :private_network,
:libvirt__network_name => "test",
:libvirt__forward_mode => "route",
:libvirt__dhcp_enabled => false,
:libvirt__guest_ipv6 => "yes",
:libvirt__ipv6_address => "fc00::",
:libvirt__ipv6_prefix => "64"
When the :ip is ipv6, set the 'static6' type, so that we select the
correct _static6.erb template to configure the interface in the guest.
With the following configuration, ipv6 works out of the box on CentOS 8:
(1..2).each do |i|
config.vm.define "node#{i}" do |node|
node.vm.hostname = "node#{i}"
node.vm.network :private_network,
:ip => "fc00::#{i+9}",
:netmask => "64",
:libvirt__dhcp_enabled => false,
:libvirt__forward_mode => "veryisolated",
:libvirt__network_name => "test"
end
end

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
Starting from version 0.7.0 (https://newreleases.io/project/github/vagrant-libvirt/vagrant-libvirt/release/0.7.0), always_destroy is set to true by default for any network.
However, in certain cases, it would be useful to keep the management network, especially when it has been already configured (externally) with Static IP leases.
This option allows to change the always_destroy behaviour for the management network.
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.

Adjust handling to use a method reference instead of attempting to
update the env value as that only appears to be available to actions
further down the chain and any changes are not visible during recovery
when exercised for real.
By passing a function reference can limit the actions that can be taken
to only allow a single call that will set a flag internal to the clean
up action.
Fixes: #1328
Switch to dedicated actions to trigger destroy/halt via the recovery
mechanism if the VM bring up has failed to complete the bring up of the
machine.
Fixes: #1328
This requires that the qemu_use_agent is enabled and at least one
network is defined in the Vagrantfile that is either private or public.
The restriction that qemu_use_agent need be enabled may be removed
subsequently for networks using a static IP address. That should be
considered a subsequent problem.
Fixes: #1204Fixes: #1124Fixes: #1057
Consolidate actions around starting the VM into a single place, and
re-order the call to the CreateNetworkInterfaces to allow it to be used
during initial bring up without needing to duplicate the remaining start
actions in the up process.
Facilitate the injection of a default channel when qemu_agent is set to
true to make enabling it's use a simple `qemu_agent = true` for most
cases.
Where custom values are needed, they can be provided and the code will
skip adding a corresponding entry, or if necessary the user can add an
entry and mark it disabled similar to how synced folders work.
Closes: #1341
List network devices to trigger a side effect to ensure the
qemu-bridge-helper will run correctly for users of the modular daemons.
It is likely that this should be done for sessions to support resolving
the correct virtual bridge device anyway, however that is more involved
and maybe superseded by not needing a network interface should qemu
agent be able to act as a communicator. Or to perform port forwarding
using qemuargs to allow SSH access directly in.
Fixes: #1258
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 destroying domains were there are multiple box volumes to be
removed, need to perform a series of checks to establish that the
correct volumes are being removed.
- check if device aliases are in use
- process the box volume removals first
- detect if disks attached outside of vagrant-libvirt
- prefer aliases for additional disks
- avoid use of devices for multiple disks to detect as currently
assigned incorrectly.
- fallback to detecting number of box volumes to determine
point at which additional disks start
Attempts to flag a number of cases where behaviour might be incorrect to
help users spot when vagrant-libvirt may accidentally remove something
it shouldn't.
To facilitate using session on a remote instance, ensure the system_uri
configuration attribute is by default derived from the default uri
provided or constructed based on other settings, so that it contains any
host and transport settings.
With the rework to use the default connection to retrieve the domain to
allow running of the qemu agent, no longer necessary to use a read
write system connection, and can revert to a read-only connection that
requires less privileges.
This should remove an occurrence of polkit requesting a password when
bringing a VM up using a session connection.
Fixes: #1342
Adjust the order of checks around use of qemu sessions to allow use of
the agent as a priority when enabled, which should remove the need to
retrieve the address from the system connection when enabled.
Additionally adjust the call to the agent to ensure it uses the default
connection to retrieve the correct domain, rather than forcing the
system connection, which will fail to find the domain if it was created
via a user session.
Add tests that validate most of this behaviour, as well as resulting in
some minor fixes around downcasing the mac address for comparisons, and
also using instance mocks with rspec instead of pure doubles to help
catch false positives where mocks are allowing calls that done exist.

Add a unit test for the prepare nfs settings action to act as a
regression test for the recent fix to avoiding modifying a frozen string
literal.
As part of this fix how the communicator is returned via a call to a
machine for testing purposes and remove an obsolete expect from the
wait till up tests as the code that would result in the communicator
being called has been removed.
Ensure that nfsd is not required to run the tests by mocking out the
host capability check.
When enabling video_accel3d, as graphics_gl is typically required, will
by default set it to true unless explicitly set to false.
