Convenience of shutdown/poweroff in a virtual machine

At one time, shutting down an OS/2 guest under VirtualBox meant full shutdown and virtual powerdown. With recent versions of VirtualBox (5.x), however, this has not been the case.

We’ve noticed, and we’ve done some work to address this.

Did you know that Arca Noae’s ACPI driver runs just fine under these latest builds of VirtualBox? Using the ACPI driver, it is possible to configure the OS/2 (or eComStation) guest machine for complete poweroff using ACPI, just as you might configure a physical workstation.

If you’ve thought that the Arca Noae Drivers and Software subscription didn’t bring value to your virtual OS/2 experience, think again. Now is a great time to subscribe.

Dramatically improve your virtual machine’s network performance

Current VirtualBox recommendations are to use the virtual Intel network cards for guest machines and to configure for bridged networking. Until now, the only choice for OS/2 was the older, IBM-supplied, Intel E1000 driver. The result? Performance just slightly better than the default AMD PCnet-FAST III virtual adapter.

Now, however, there is a choice. Arca Noae subscribers may use the all-new MultiMac Legacy EM driver (MMLEM). This driver is a breakthrough for virtual machines running under VirtualBox, with performance measured at more than twice the throughput of the older driver.

Some comparisons from netio 1.3 across a 1Gbps unmanaged switch, from an OS/2 VM running the latest 32-bit TCP/IP stack to a 64-bit Linux server running on bare metal1:

E1000:

TCP connection established.
Packet size  1k bytes:  15.04 MByte/s Tx,  9168.71 KByte/s Rx.
Packet size  2k bytes:  19.64 MByte/s Tx,  11.99 MByte/s Rx.
Packet size  4k bytes:  22.38 MByte/s Tx,  13.58 MByte/s Rx.
Packet size  8k bytes:  23.72 MByte/s Tx,  17.62 MByte/s Rx.
Packet size 16k bytes:  24.83 MByte/s Tx,  20.62 MByte/s Rx.
Packet size 32k bytes:  19.52 MByte/s Tx,  17.82 MByte/s Rx.
Done.

MMLEM:

TCP connection established.
Packet size  1k bytes:  13.19 MByte/s Tx,  9183.80 KByte/s Rx.
Packet size  2k bytes:  18.65 MByte/s Tx,  12.20 MByte/s Rx.
Packet size  4k bytes:  27.93 MByte/s Tx,  14.98 MByte/s Rx.
Packet size  8k bytes:  39.91 MByte/s Tx,  19.29 MByte/s Rx.
Packet size 16k bytes:  50.39 MByte/s Tx,  22.74 MByte/s Rx.
Packet size 32k bytes:  28.07 MByte/s Tx,  19.19 MByte/s Rx.
Done.

(Note that the falloff between 16 and 32k appears to be an issue within VirtualBox itself, as the same tests, when run against the host machine, actually report an improvement in throughput for the 32k packet size over the 16k one. A 32-bit Linux guest does not show this falloff.)

As you can see, peak transmit throughput, using 16k byte packets, went from 24.83MByte/s (198.64Mbps) to 50.39MByte/s (403.12Mbps). If you are transferring large files across your network to and from your OS/2 VM, this implies a possible reduction in the amount of time it takes for such transfers by more than one half2.

In addition, while the above tests were run using the Intel PRO/1000 MT Desktop (82540EM) virtual network card in the guest, the MMLEM driver also supports the Intel PRO/1000 T Server (82543GC) and Intel PRO/1000 MT Server (82545EM) virtual network card options available in VirtualBox 5.x, either of which may yield even better throughput (the older IBM-supplied driver does not support these server-class cards).

There are other benefits of the Arca Noae Drivers & Software subscription for virtualized users of OS/2, including full shut down and virtual power off of the VM when using Arca Noae’s ACPI PSD. So if you thought there wasn’t much value in subscribing just to run virtual machines, you might want to look again.

  1. Guest machine running eCS 2.1, configured with 2GB RAM, Intel PRO/1000 MT Desktop (82540EM) virtual network card, 32-bit TCP/IP stack, default sockets. Host machine running openSUSE LEAP 42.1 x64, 16GB RAM, single Intel 82567LF-2 onboard network adapter, and default adapter settings. NETIO target (host) machine running openSUSE 13.2 x64, 32GB RAM, dual Broadcom NetXtreme II BCM5708 onboard network adapters, in bonded active backup configuration, with default adapter settings for the physical bond slaves. Switch was Cisco SR2024 (unmanaged 10/100/1000).
  2. Many factors contribute to overall network throughput, including protocol, aggregate traffic, CPU activity, etc. These figures are meant as a guideline and not a guaranty of performance.

Who’s speaking at Warpstock Europe?

There will be plenty of information on hand at this year’s Warpstock Europe event. Here’s a sampling of what to expect from Arca Noae:

Saturday, David Azarewicz will be presenting on device driver progress and plans for the future (Blue Lion will be a milestone, but not the end of the road, by any means).

Also on Saturday, Lewis Rosenthal will be discussing what to expect in the Blue Lion package. While all of the details have not been set, we have a pretty good idea of what will be included.

Later in the afternoon, Steven Levine will pick up on Arca Noae SNAP. Learn what is coming next for this accelerated video driver.

We will return on Sunday with an update on YUM and RPM and how these technologies play an important role in Blue Lion by Lewis Rosenthal, as well as future plans for the well-received Arca Noae Package Manager.

Arca Noae’s last presentation on Sunday will be from Alex Taylor via Skype, discussing printing and fonts.

Between Arca Noae staff and the other presenters, there should be something for everyone. Arca Noae is the exclusive source for Warpstock Europe tickets. If you haven’t yet purchased your tickets, please visit our store today.

Blue Lion, by Arca Noae

Presentation: Blue Lion – A First Peek

We’ve added a new item to our Presentations, Whitepapers, & Case Studies page.

Blue Lion – A First Peek was a presentation given by Lewis Rosenthal via Skype to the Dutch OS/2 Users Group (eCS-gg), Saturday, January 9. The discussion focuses on Blue Lion’s new Preboot environment, including screenshots of current alpha builds, and references some planned features of the new installation media and maintenance environment. The presentation is provided as a PDF.

Arca Noae: a new name, but with familiar faces

Arca Noae has been active for about half a year; our online store opened mid-November, and our popular drivers and software subscription has seen several updates. We’ve made numerous news postings, as well as personal appearances at Warpstock. We’ve even added a FAQ page and a roadmap to our site. Still, some people seem to be confused as to why Arca Noae was created, who works for Arca Noae, and what Arca Noae’s long term goals are.

The UEFI Forum

Arca Noae joins the UEFI Forum as an Adopting Member

For immediate release:

Leesburg, Virginia, USA

Arca Noae, LLC, a Delaware-based Limited Liability Company, is pleased to announce their membership in the UEFI Forum.

The UEFI (Unified Extensible Firmware Interface) specification defines a new model for the interface between personal-computer operating systems and platform firmware. The interface consists of data tables that contain platform-related information, plus boot and runtime service calls that are available to the operating system and its loader. Together, these provide a standard environment for booting an operating system and running pre-boot applications. Essentially, this layer provides a replacement for the traditional BIOS, and is the future of small computing architecture.

The UEFI Forum is a clearinghouse for all current, related documents pertaining to UEFI, the UEFI specification, and its adoption by manufacturers and software developers.

In addition, the UEFI Forum performs a similar function for ACPI (Advanced Configuration and Power Interface). Arca Noae develops and maintains the current ACPI implementation for the OS/2 and eComStation platform.

Arca Noae is committed to running OS/2 on current hardware. UEFI, like ACPI, is a continuation of the trend to move more functions from the BIOS to the operating system. Arca Noae is looking into how this new technology can be supported under OS/2 in the future.
