The change extends vmimage.subr to handle a new parameter, VMFS, which
should be equal to either "ufs" or "zfs". When it is set to ZFS, we use
makefs to create a bootable pool populated using the same dataset layout
as bsdinstall and "poudriere image" use. The pool can be grown using
the growfs rc.d script, just as in UFS images.
This will make it easy to provide VM and cloud images with ZFS as the
root filesystem. So far I did not do extensive testing of cloud images;
I merely verified that creation of ZFS-based AWS AMIs works and allows
me to create amd64 and arm64 EC2 instances with ZFS as the root
filesystem.

Using makefs instead reduces the privileges needed to build VM images,
simplifies the script (no need to copy files to a fresh image at the end),
and improves portability by allowing generation of cross-endian images.
As a result of the last, this patch also adds support for generation of
powerpc64 and powerpc64le VM images.
No other changes to the output. Tested and working for both amd64 and
powerpc64 targets.

These images were switched to MBR in r281876 as a way to cope with a
hard-coded partition GUID in QEMU's default EFI firmware. Enough time
has passed that this is no longer a problem; QEMU versions >= 4.0
include a copy of edk2 EFI firmware that can detect the root filesystem
properly. Alternatively, sysutils/u-boot-qemu-arm64 can be used.
Switch back to building these images with a GPT partition table, and
re-enable the swap partition.

GPT scheme. UEFI needs to know the unique partition GUID
with GPT, which changes each time. Specifically, the QEMU
EFI BIOS file has this hard-coded.[1]
Since the GPT labels are now unavailable, unconditionally
label the root filesystem as 'rootfs' with newfs(8), since
it does not hurt anything anywhere else. For the arm64 case,
'/' is mounted from /dev/ufs/rootfs; for all other VM images,
'/' is mounted from /dev/gpt/rootfs.
Unfortunately, since the /dev/gpt/swapfs label is also lost,
set NOSWAP=1 for the arm64/aarch64 images. This is temporary,
until I figure out a scalable solution to this. But, a certain
piece of softare was written "very fast", and ended up living
for 15 years. We can deal with this for a week or so.

a new filesystem before packaging it into a disk image. This prevents
"remnants" of deleted files from showing up in the VM images, and reduces
their compressed size (by about 10% for the cloudware images) as a result.
Looks good to: gjb
defaulting VMCONFIG to /dev/null, and additionally
ensuring VMCONFIG is not a character device before it
is sourced.
While here, be sure to exit if usage() is called.
This should effectively be no-op, but the usage() output
was discovered while investigating a larger issue.

r273825:
Avoid hard-coding the Azure image file format. While here,
avoid using OSRELEASE for the output file name.
r273826:

r273833:
Initial commit providing a mechanism to create openstack images
as part of the release build.
r273836:
Fix output file name for openstack images. No further conversion
is necessary for this VM file target, so there is no need to append
the '.raw' suffix here.
r273944:
Uncomment the cloudinit rc.conf(5) line.
r274069:
Add line continuation so OPENSTACKCONF is actually included in the env(1).
r274070:

Add primitive (untested) PowerPC/PowerPC64 VM image support.
Note: As it is currently written, the /boot/pmbr and

r274729 (cperciva):
Unmount filesystem and destroy md before we read the vnode from
disk and package it into a disk image. Otherwise we end up

Merge duplicative vm-CLOUDTYPE targets before additional duplication
gets added by the impending arrival of ec2 and gcloud.
r274771 (cperciva):
Add NOSWAP option which can be set by a vmimage.conf file to specify
that no swap space should be created in the image. This will be used
by EC2 builds, since FreeBSD/EC2 allocates swap space on "ephemeral"
disks which are physically attached to the Xen host node.

VM_EXTRA_PACKAGES is empty.
In vm_extra_pre_umount(), cleanup downloaded packages if pkg(8) was

Remove vm_extra_install_base() from the openstack.conf entirely,

no way to tell if the environment will be able to use the
graphics-mode console.
r277184:
Enable password-less sudo for openstack images.
r277186:
Update the VM_EXTRA_PACKAGES list for the openstack images.
The documentation suggests doing a "just fetch this and run it"-style
bootstrap, from which the list of dependencies was obtained (in
github, at: pellaeon/bsd-cloudinit-installer)
There is one Python dependency unmet, oslo.config, which is not in
the Ports Collection.
r277187:
Add a comment to note that setting hw.vga.textmode=1 is temporary.
r277250:
Remove vm_extra_install_base() for the Azure image, now that the
waagent exists in the ports tree.
Add sysutils/azure-agent to the VM_EXTRA_PACKAGES list.
In vm_extra_pre_umount(), remove the explicit pkg(8) install
list, as dependencies are resolved by sysutils/azure-agent.
r277251:

values and a description.
Add the AZURE_DESC and OPENSTACK_DESC descriptions.
r277252:
Update release(7)
r277253:

VM and cloud provider images.
Add VHD_DESC, VMDK_DESC, QCOW2_DESC, RAW_DESC image descriptions.
Format the output to make a bit more readable.
Update release(7) to document the list-vmtargets target.
r277263:
Add initial support for the GCE (Google Compute Engine) cloud hosting
provider image.
r277264:
Style and line length cleanup.
r277383:
Remove the console setting from rc.conf(5), which is not used there.
While here, set console to include vidconsole in the loader.conf(5).
r277384:
Fix an indentation nit.
No functional changes.
r277393:
Remove the pkg-clean(8) call from vm_extra_pre_umount() since the
function is often overridden.
Add vm_extra_pkg_rmcache() to call pkg-clean(8) to avoid duplicated
code.
r277394:
Move resolv.conf(5) removal back to vm_extra_pre_umount() where it
belongs.
The GCE image needs resolv.conf(5) to exist (created as part of the
image setup), so it cannot be removed.
r277395:
Comment the line that configures ttys(5) to 'off', which makes it
impossible to test that the image boots.
Add a note explaining why the line is commented, and not (yet) removed
entirely.
r277438:
Move the 'install' bits that are specific to virtual machine images
from the Makefile to Makefile.vm.
Rename the 'install' target to 'release-install', and add a new
'vm-install' target.
Add a new 'install' target that invokes the new targets.
r277439:
Add WITH_CLOUDWARE to the list of make(1) variables for the release
build.
r277447:
Remove hw.vga.textmode=1 from the VM image loader.conf, which was
included during test builds and not intended to be included when
merging this project branch back to head.
r277455:
Remove mk-azure.sh, which is no longer needed.

There may be some very sharp edges here while refactoring.
- Move amd64/mk-vmimage.sh -> scripts/mk-vmimage.sh.
- Remove vm-base target from Makefile.vm.
- In vm-image target, use getopts flags for argument passing.
- Create tools/vmimage.subr, containing default and prototype
for the following functions that are used to drive the build,
run in this order:
vm_install_base()
vm_extra_install_base()
vm_extra_install_packages()
vm_extra_install_ports()
vm_extra_enable_services()
vm_extra_pre_umount()
vm_create_disk()
vm_extra_create_disk()
- In tools/azure.conf, override:
vm_extra_install_base()
vm_extra_pre_umount()
vm_extra_create_disk()
- In tools/openstack.conf, override:
vm_extra_install_base()
vm_extra_pre_umount()

of the FreeBSD release builds.
This adds a make(1) environment variable requirement,
WITH_VMIMAGES, which triggers the virtual machine image
targets when not defined to an empty value.
Relevant user-driven variables include:
o VMFORMATS: The virtual machine image formats to create.
Valid formats are provided by running 'mkimg --formats'
o VMSIZE: The size of the resulting virtual machine
image. Typical compression is roughly 140Mb, regardless
of the target size (10GB, 15GB, 20GB, 40GB sizes have been
tested with the same result).
o VMBASE: The prefix of the virtual machine disk images.
The VMBASE make(1) environment variable is suffixed with
each format in VMFORMATS for each individual disk image, as
well as '.img' for the source UFS filesystem passed to
mkimg(1).
This also includes a new script, mk-vmimage.sh, based on how
the VM images for 10.0-RELEASE, 9.3-RELEASE, and 10.1-RELEASE
were created (mk-vmimage.sh in ^/user/gjb/thermite/).
With the order in which the stages need to occur, as well as
sanity-checking error cases, it makes much more sense to
execute a shell script called from make(1), using env(1) to
set specific parameters for the target image than it does to
do this in make(1) directly.
