I install fresh Ubuntu 14. 04 server under ESXI 5.1.0.
During my installation I did not get any erorrs or strange things. My problem is when I boot machine at console screen I get messages like
[ 6.958104] intel_rapl: no valid rapl domains found in package 0 [ 7.508153] intel_rapl: no valid rapl domains found in package 0 [ 8.058695] intel_rapl: no valid rapl domains found in package 0 [ 8.609932] intel_rapl: no valid rapl domains found in package 0 [ 9.163260] intel_rapl: no valid rapl domains found in package 0
After that messages I am able to log in and my to me Ubuntu works OK. I have internet connection I am able to call apt-get update and I am able to login over SSH.
Should I investigate these errors deeply before I continue build my server.
Do I need to react on these Messages or it is ok to run Ubuntu like this.
The intel_rapl message was driving me crazy. The solution for me was to (sudo) edit/etc/modprobe.d/blacklist.conf and add blacklist intel_rapl. No more messages after reboot.
This was a change introduced in October 2013 to support Intel RAPL power capping driver in the Linux kernel. This message is non-obstructive, and when it appears it doesn‘t affect the performance or functionality of the system, since it‘s only a power management module.
If your virtualization software supports this driver (and the host supports advanced power features) then the message disappears.
You can check the source tree of the module to check what it does.
I know in virualbox you can enable PAE/NX which will solve "no valid rapl domains found in package" on Ubuntu 14.04 LTS. I don‘t know how about ESXI if it supports PAE/NX or not.
