Review request for cloudstack, Alex Huang, daan Hoogland, and Hugo Trippaers.


Repository: cloudstack-git


Description
-------

Couple changes in sysctl.conf: 
1. up the amount of connections that the svm can handle. 
2. Panic on OOM and OOPS so that ACS can act on a misbehaving SVM. 
3. nonlocal_bind to fix some situations where master to backup fails in redundant rvms.
Also adding /etc/modules to preload modules so that setting some of the sysctl settings during
boot works. For this I also changed procps runlevels.


Diffs
-----

  systemvm/patches/debian/buildsystemvm.sh 7f6188a 
  systemvm/patches/debian/config/etc/modules PRE-CREATION 
  systemvm/patches/debian/config/etc/sysctl.conf 586d5bd 

Diff: https://reviews.apache.org/r/18309/diff/


Testing
-------

We have been running these adjustments in production on our own 4.2 and 3.0 SVM with success
for a couple months now.


Thanks,

Joris van Lieshout
