The export process now exports the VM directly from the build directory
into the output directory. There are no intermediate steps or copying of
files involved. This means that there is no longer any benefit in having
a separate directory to house the VHD files - see #5206 for the
reasoning behind the introduction of this feature.
If a user wishes to house the build files on a separate disk from the
output directory (perhaps for performance reasons or due to disk space
limitations) they can still do so through the use of `temp_path`.
PR #5631 introduced code to build/create disks directly in the output
directory if `skip_export` was set in an attempt to optimise the build
process. These are no longer required.
* Report compaction results
* Failure to find any disks under the supplied path is treated as a
'soft' error and a warning message will be printed in place of the
compaction result. Any other failure will cause the build to fail.
Commit 3fc2defb6 altered the directory structure associated with an
exported VM. The changes mean that the export process now stores the
exported machine files and folders under a folder with name 'vm_name' in
the output directory.
This commit restores the previous behaviour whereby the exported machine
files and folders were stored directly in the output directory. This
allows us to keep the efficiency improvements introduced with 3fc2defb6
while maintaining backward compatibility.
By default the Export-VM command creates three folders in the specified
export directory - 'Virtual Hard Disks', 'Virtual Machines' and
'Snapshots'. When a machine with no associated snapshots is exported the
'Snapshots' directory is empty.
Prior to 3fc2defb6 the Snapshots folder was not copied/incorporated into
the output directory at all. This was a bug.
This commit preserves the legacy behaviour by not including an empty
Snapshots directory in the export. However, if there *are* Snapshots
associated with the VM, they are now moved into the output directory
along with the usual directories containing disks and VM metadata. This
prevents warnings/errors on import due to missing snapshots.
* Fixes a bug that caused the build to error if users did not
explicitly set `skip_compaction:true` when setting `skip_export:
true`. See #6392.
* Improves the efficiency of the compaction and export process by
reordering the compaction and export steps.
* Further improves the efficiency of the compacting step through
compacting the vmd* file directly rather than creating and then
operating on a copy.
* The changes mean the export process now stores the exported machine
files and folders under a folder with name 'vm_name' in the output
directory. Previously the exported machine files and folders were
stored directly in the output directory.
- Logging error if vmconnect.exe fails.
- Using StepRun struct rather than StateBag for command Cancel function
- Better handling in Disconnect when headless is true or vmconnect failed in Start
vmconnect.exe comes as part of Hyper-V and is the tool used by Hyper-V Manager to connect with a virtual machine. This commits sets behaviour the same as virtualbox and vmware to display the virtual machine connection unless headless is set in the template.
Run now takes a context as well as a statebag. We'll assign the context
to the blank identifier to prevent namespace collisions. We'll let the
step authors opt-in to using the context.

[A recent breaking change upstream in Golang's crypto
library](e4e2799dd7)
has broken SSH connectivity for a few builders:

```
Specifying HostKeyCallback as insecure should make things work again
and would make sense for packer's use case.
If using a builder that has an http server set up for file transfer,
expose the connection info to the shell provisioner through the environment
variable PACKER_HTTP_ADDR.
Closes#2869
To enable nested virtualization, mac spoofing, no dynamic memory and at least 4gb of ram should be set for the vm. Set warning if this has not been done.
Detected Virtualization Extensions are supported by the machine your are running on, as it only works for Windows 10 and Windows Server 2016 onwards.
