=== Virtual Machine Disk Images ===

VM disk images are available for the amd64, i386, and aarch64
architectures.  Disk images may be downloaded from the following URL
(or any of the FreeBSD download mirrors):

    https://download.freebsd.org/ftp/releases/VM-IMAGES/12.1-RC2/

The partition layout is:

    ~ 16 kB - freebsd-boot GPT partition type (bootfs GPT label)
    ~ 1 GB  - freebsd-swap GPT partition type (swapfs GPT label)
    ~ 20 GB - freebsd-ufs GPT partition type (rootfs GPT label)

The disk images are available in QCOW2, VHD, VMDK, and raw disk image
formats.  The image download size is approximately 135 MB and 165 MB
respectively (amd64/i386), decompressing to a 21 GB sparse image.

Note regarding arm64/aarch64 virtual machine images: a modified QEMU EFI
loader file is needed for qemu-system-aarch64 to be able to boot the
virtual machine images.  See this page for more information:

    https://wiki.freebsd.org/arm64/QEMU

To boot the VM image, run:

    % qemu-system-aarch64 -m 4096M -cpu cortex-a57 -M virt  \
	-bios QEMU_EFI.fd -serial telnet::4444,server -nographic \
	-drive if=none,file=VMDISK,id=hd0 \
	-device virtio-blk-device,drive=hd0 \
	-device virtio-net-device,netdev=net0 \
	-netdev user,id=net0

Be sure to replace "VMDISK" with the path to the virtual machine image.

=== Vagrant Images ===

FreeBSD/amd64 images are available on the Hashicorp Atlas site, and can
be installed by running:

    % vagrant up

=== Upgrading ===

The freebsd-update(8) utility supports binary upgrades of amd64 and i386
systems running earlier FreeBSD releases.  Systems running earlier
FreeBSD releases can upgrade as follows:

	# freebsd-update upgrade -r 12.1-RC2

During this process, freebsd-update(8) may ask the user to help by
merging some configuration files or by confirming that the automatically
performed merging was done correctly.

	# freebsd-update install

The system must be rebooted with the newly installed kernel before
continuing.

	# shutdown -r now

After rebooting, freebsd-update needs to be run again to install the new
userland components:

	# freebsd-update install

It is recommended to rebuild and install all applications if possible,
especially if upgrading from an earlier FreeBSD release, for example,
FreeBSD 11.x.  Alternatively, the user can install misc/compat11x and
other compatibility libraries, afterwards the system must be rebooted
into the new userland:

	# shutdown -r now

Finally, after rebooting, freebsd-update needs to be run again to remove
stale files:

	# freebsd-update install

Games: Stellaris, Crusader Kings III and More

  • Stellaris: Federations and Stellaris: Lithoids Species Pack announced at PDXCON

    PDXCON is now in full swing and the announcement are being handed out like candy. First up, Paradox Interactive and Paradox Development Studio have announced Stellaris: Federations and Stellaris: Lithoids Species Pack.

  • Crusader Kings III announced for release next year, to be more welcoming to new players

    As I suggested they would when setting Crusader Kings II permanently free (but not the DLC), Paradox Interactive have announced Crusader Kings III. "Crusader Kings III is a grand medieval simulator where you are free to live out any plausible ruler fantasy that we could think of - but not without challenge." says Henrik Fåhraeus, the Game Director. "Seeing its predecessor explode in popularity was very satisfying, especially considering that user friendliness was never our primary goal. Now we have a chance to address an even larger audience."

  • Prison Architect - Psych Ward: Warden's Edition expansion announced (plus another coming)

    I think we all saw this coming when Paradox Interactive picked up the rights to Prison Architect, with Double Eleven taking on further development. The first proper DLC has been announced at PDXCON named Prison Architect - Psych Ward: Warden's Edition. Psych Ward was previously a console exclusive DLC, so it's good to see it make it onto PC. However, it does include new added features not in the original DLC and it will launch along side a free content update for everyone. It's not exactly a small pack either, it actually sounds like it's going to be adding quite a bit to the game. Paradox also gave it a release date of November 21, so you won't exactly have long to wait to really find out.

  • BATTLETECH: Heavy Metal brings more classic 'Mechs and new weapon systems, releasing in November

    Even more news from PDXCON! Harebrained Schemes and Paradox Interactive have now properly announced the BATTLETECH: Heavy Metal expansion to bring more destruction.

  • Hearts of Iron IV: La Résistance expansion and a significant free update announced

    Paradox Development Studio and Paradox Interactive are expanding another of their grand-scale strategy games, with Hearts of Iron IV: La Résistance announced during PDXCON. Not just that, as they usually do they also confirmed a "significant" free content update will be released to all players. The free update will include a reworking of the resistance system, interface improvements to battleplans and air operations plus many other "quality of life improvements".

  • Bioshock 1 & 2 | Linux Gaming | Ubuntu 19.04 | Steam Play

    Bioshock 1 & 2 running through Steam play.

  • Continuing the Counter-Strike 20th anniversary Valve put out skins, plus a possible Operation and update coming

    After starting off the celebration for Counter-Strike turning 20 back in June with the retro version of Dust II, Valve have now added a refreshed version of the map Cache and a themed Weapon Case and Sticker Capsule. We're expecting some bigger updates to come but let's go over what they've already done. [...] VNN's Tyler McVicker also released another of his highly speculative videos talking about lots of other things that could be pointing to a new operation. With a possible update coming that may include: custom Danger Zone modes, a new Danger Zone map, new Danger Zone weapons, co-op missions, hats and other wearable items, player taunts and more being speculated on. I personally hope Valve do put out a big update, since their celebration so far has been a bit lacklustre. An old map, a refreshed map and some skins you have to pay for. Not exactly big or exciting really so far. Speaking personally again, I'm still very much enjoying Danger Zone so if they do expand it again I will be quite pleased.
