443327 - Bring up physical hardware to isolate VMWare as a cause of unit test failures

Status: RESOLVED FIXED

(Release Engineering :: General, defect, P1)

Description

[Mike Schroepfer]

qm-centos5-moz2-01 and 02 are showing intermittent failures.  (see blocked bugs)

No idea whether this is a machine configuration issue, VM issue, or a bad test - but let's try and isolate all variables at once.  To start let's go ahead and bring up a 2-3 physical hosts (we can steal 2 talos mini's if that works) to see if they are more reliable.  

Lukas you were volunteered for this task :-)

fyi: 

1) qm-moz2mini01 is a mac mini

2) qm-win2k3-03 is a DL360 with 3.5gb ram, 2cpu.

3) qm-centos5-moz2-01, qm-win2k3-moz2-01, qm-centos5-03 are all VMs.

Failing in the VM only doesn't necessarily mean that VMWare is the problem. The VMs run slower, with different I/O behavior and more memory pressure. This exposes bugs.

Comment 3

[Lukas Blakk [:lsblakk] use ?needinfo]

We have brought up hardware for both linux and win32:

qm-centos5-moz2-02-hw 
qm-win2k3-unittest-hw

Both report to http://tinderbox.mozilla.org/showbuilds.cgi?tree=Firefox

Okay to close this bug?

Yep - please do
