Hey guys, Sorry to insist on this subject but, the time for releasing DPDK 2.2 is near and DPDK build with Xen 32-bit is broken. If DPDK doesn't fix this, there will be no way to enable XenVirt support for next Ubuntu LTS 16.04, which is a shame... I'm planning to use DPDK on Xen domUs (PVM, HVM, XenServer and on Amazon EC2) powered exclusively by a supported version of Ubuntu but, it is broken now... So, please, can someone take a look into this? :-P Thanks in advance! Cheers! Thiago
