* removed packer.Cache and references since packer.Cache is never used except in the download step. The download step now uses the new func packer.CachePath(targetPath) for this, the behavior is the same.
* removed download code from packer that was reimplemented into the go-getter library: progress bar, http download restart, checksuming from file, skip already downloaded files, symlinking, make a download cancellable by context.
* on windows if packer is running without symlinking rights and we are getting a local file, the file will be copied instead to avoid errors.
* added unit tests for step_download that are now CI tested on windows, mac & linux.
* files are now downloaded under cache dir `sha1(filename + "?checksum=" + checksum) + file_extension`
* since the output dir is based on the source url and the checksum, when the checksum fails, the file is auto deleted.
* a download file is protected and locked by a file lock,
* updated docs
* updated go modules and vendors
Windows Hypervisor Platform (WHPX) is the Windows counterpart to HVF and
KVM. It's an operating system provided component that provides
virtualization acceleration support.
This is kind of the missing counterpart to https://github.com/hashicorp/packer/pull/6193.
QEMU 2.12 also added support for WHPX.
There's no support for libvirt on Windows so nothing was added in those
areas.
The popular QEMU for Windows distribution does not have WHPX support
built-in for legal reasons as the maintainer does not wish to use or
obtain any part of Microsoft's SDK to compile the distribution.
When booting from a disk image, the Qemu builder resizes the disk to 40000
which is not a multiple of 1kB. This causes problems while booting from the image.
Updating the default disk size to 40960 fixes this issue
This option allows to set the extension of the ISO file after download.
Defaults to "iso". It makes sense for building Mac OS X guests, where the
bootable image is actually a DMG, not an ISO.
In particular, it is important for "parallels-iso" builder to set the right extension.
