462190 - create two new VMs for "sse disabled" unittests

Status: RESOLVED FIXED

(mozilla.org Graveyard :: Server Operations, task)

Description

[Justin Fitzhugh]

Build needs a VM instance with SSE disabled.  Failing that, we need to disable SSE on a mac mini.  Is this possible?  If so, how?  We'll need a Windows and Linux VM or mini for build, built of the ref images for unit testing.

To clarify a little:

1) We need two VM clones created: one win32 (from win2k3sp2-vc8tools-ref-vm) and one linux (from CentOS-5.0-ref-tools-vm). 

2) Once these VMs are created, rsayre will show us how to disable SSE on these VMs.

3) We'll then try to see if/how things work. If all goes smoothly, the idea here is to have these become new platforms that run unittests on each nightly. There is no plan to build or to run perf tests on these platforms.

Phong/IT will handle this step - something they'll have to talk to vmware about.

If rsayre already knows, that'll be quicker than going through vmware!

I was in the meeting where he said he didn't - hence why I opened an IT bug.

Phong - 

I'm sorry I misread your request, yes you can do this, you will just need to mask out the features from the VM, in the settings for the VM go to options, and then CPUID mask, and advanced. This is where you will enter the mask.


I would recommend testing this with a cpuid program or our cpuid bootable cdrom: http://vmware.com/download/shared_utilities.html

from: http://kb.vmware.com/kb/1993

The mask should be:
ecx level 1:  ---- ---- ---- 00-- ---- --0- ---0 -0-0
edx level 1:  ---- ---- ---- --0- ---- ---- ---- ----

John:  what do you want to name these 2 VM's and which network should they be on?

moz2-win32nonsse-slave01
moz2-linuxnonsse-slave01

phong: for the purposes of this experiment, please put these VMs on the devESX host, not in the production build network.

Comment 9

[Phong Tran [:phong]]

I've put them on dev-vmware01.

Sorry, Phong. I've just been corrected. Can you please move these VMs into the build network after all, along with our other build slaves? The new VMs not being used yet, so you can powerdown anytime if you need to.

They are being migrated now.
