2016-08-09hugepage_detect: Change hugepage detection to check for free hugepagesChristian Trautman1-20/+55
Change hugepage detection to check if hugepages are configured. Also verifies enough free hugepages are available based on test configuration. Will result in an exception if not enough hugepages are found. This performs the check based on the guest memory configs as well as the dpdk socket configs. Adds some new methods to check for free hugepages based on all hugepages or for socket free hugepages. Adds new logging indicitaing needed and free hugepages as well as info level event if hugepages are not configured at recommended 1GB size.

2016-05-04bugfix: Fix creation of vsperfenv in UbuntuMartin Klozik1-1/+2
Wrong version of virtualenv was executed in Ubuntu specific script. So python modules could not be installed and vsperf was not working. Hugepages mount point is newly created inside sudo environment to avoid issues with permissions.

2016-01-21bugfix: mount hugepages for PVP and PVVP scenariosMartin Klozik1-0/+102
Hugepages are used by both DPDK and Qemu. However they were mounted only in case, that OVS with DPDK support was detected. Thus code has been modified to mount hugepages in case that either DPDK usage or QEMU usage is detected.
