Getting started with Beta 3
If you are new to z86VM and would like a beta copy, please send an email and you’ll receive an ID and password to get the code off of our FTP server. Please put z86VM Beta in the subject line of all correspondence. Perhaps even easier – just fill in the contact form below. Detailed installation instructions are included below.
We’ve released the beta because we wanted to learn from you, the customer, what is good and bad and also to check our documentation, identify any restrictions in the code and capture new product requirements. We have found it is capable of doing some very interesting demos as to possibilities for how it can be used in the future. We are concerned about expectations for our product. We know we have performance and quality work to do before it becomes generally available. We ask that you understand that.
We would like to make the beta a good experience for you. We may ship additional beta’s with new functions, fixes and performance enhancements. If you want to show someone a demo because you think it is “cool”, “exciting”, “the future”, or any other kind words, that would be wonderful. We ask that you not show nor publish any performance data associated with your experience in the beta, without permission from Mantissa. We are not done developing the product yet and we hope to further improve the experience. That’s also why we have no published nor target general availability date yet. We will not release the code until it meets our own expectations.
If you don’t feel that you can adhere to the spirit of our beta, please don’t request to participate.
Generally speaking, systems which predate model z196 and z114 do not have the necessary instruction support for this installation.
This is the THIRD in a series of distributions. The timing and content of distributions will depend on problems identified and addressed at each stage of the beta. The FIRST Beta was Damn Small Linux (DSL) kernel level 2.4 with a fluxbox window manager. The SECOND Beta is SME Linux 7.6 with a 2.6 kernel. See wikipedia.org for details. This THIRD Beta includes both SME Linux 8.1, with its additions of more middleware, including the LAMP Stack (Linux, Apache web server, MySQL database and PHP) and WordPress. and DSL 2012 edition.
** New note: Experience has told us that you need to initiate the following FTP from a Windows or Mac system and then locally update it to your zVM system. There seems to be an issue with the FTP Client on zVM that is inhibiting a successful download. Once downloaded to the desktop system, from that system, open a connection to your zVM and PUT the files there.
Instructions for download Beta 3 (start)
ftp ftp.mantissa.com <http://ftp.mantissa.com>
user: (Insert userid received in email)
pw: (insert case sensitive password received in email)
get tightvnc-2.0.2-setup.exe <== if you need a VNC Client
Instructions for download Beta 3 (end)
**New Note: We want to keep you up to date with changes within the Beta and new functionality. Please look at our Blog site: http://www.mantissa.com/category/z86vm/ regularly to stay abreast. Don’t hesitate to post your own experiences or questions that you think might be applicable to other customers. You’ll have to register at the site, but nothing secret nor scary about that process. We want to hear from you.
After test image customization and subsequent IPL activate z86VM stats reporting by entering (on the DEMODSL console):
//son <=== Stats on command
Echo __ //SON
11:21:06 cmu (mmudisp ) - _______ Stats display enabled
Capturing Performance Data
We are interested in several performance metrics you may obtain. The first is test script duration. Upon script termination a message (“Script took XX seconds to run”) recording duration is displayed. Please record that number. This duration may be longer than with DSL owing to increased trace overhead.
The next metric of interest is resting CPU consumption. Every ten seconds CPU consumption is reported. After you see the GUI appear in the VNC session, let the system remain idle for several minutes and collect a text clip of the statistics output from the VM guest console. It should look something like this.
11:35:00 cmu (cmumaint) - _______ x86 mips high(0) interval(0) avg over 88 cpu sec(0) x86im(0) vcpu(1045004166)
11:36:10 cmu (cmumaint) - _______ x86 mips high(0) interval(0) avg over 89 cpu sec(0) x86im(0) vcpu(1046444810)
11:37:30 cmu (cmumaint) - _______ x86 mips high(0) interval(0) avg over 91 cpu sec(0) x86im(0) vcpu(1048526709)
11:37:40 cmu (cmumaint) - _______ x86 mips high(0) interval(0) avg over 91 cpu sec(0) x86im(0) vcpu(1048636213)
Finally, we would like to see output produced by a z86VM probe command. By entering (on the z860001 console):
//probe <=== Probe command
on the VM guest console you should get a series of messages similar to these:
z86VM – Probe Name(CACHEINSTRUCTIONLINESIZE ) Count(256) Desc(Cache Instruction Cache Line Size
z86VM – Probe Name(CACHEINSTRUCTIONTOTALL1 ) Count(65536) Desc(Cache Instruction Total Level 1 Size
z86VM – Probe Name(CACHEINSTRUCTIONTOTALL2 ) Count(1572864) Desc(Cache Instruction Total Level 2 Size

z86VM – Probe Name(PIT2TICKS ) Count(21383) Desc(TimeX Pit2 ticks
z86VM – Probe Name(PIT2POSTS ) Count(106927) Desc(TimeX Pit2 posts
Clip and save.
Send Mantissa your results
We would appreciate an email containing:
- test script run time,
- resting CPU consumption,
- //probe command output
- model number of your machine.
If z86VM ABENDs for any reason, clear the z/VM guest console of the abending z86VM user and provide the following information:
“x’5B5000’ contains 16 64 bit registers, followed by 16 32 bit registers, followed by the ABEND PSW at 5B5100. The failing instruction address will be at 5B510C
“On the z86 Console, to display the registers and PSW, Enter:
CP D T5B5000.200
This will produce a dump of the system diagnostic work area (SDWA). It will look something like this:

In this Example, the failing instruction address is DD252. So to capture that data, we’ll need data before and after this failure. In this case, enter:

Email a copy of output from this storage dump. If possible, leave the guest active and await instructions .
Known Beta 3 issues:
- Cannot run SME 8 with more than 900M of memory
- When starting an operating system image, wait one minute before starting the VNC to avoid a Display device driver incompatibility. Conversely, at shutdown, it may be wise to kill the VNC prior to shutdown completion and look for the z86user WTO that says shutdown has completed. (a build issue)
- If z86vm hits an internal error, there will be a wait state issued. Data collection information is described above.
- The STOP command of the ZVOS console doesn’t work properly. Z86 continues to run. (that’s why the wait state was added).
- Console commands must start in column 1, including commands to drop into CP mode.
- zvcopy will take down the IO server if there isn’t enough space on the x86 storage side.
- Firefox doesn’t work properly on the DSL 2012 distro
- VNC connect/reconnect from one device to another doesn’t work with the zVM VNCServe. Need to test with the DSL VNCServer.
- No testing has been done with multi-media sound or video files yet
