Hey guys, Is there an easy / fast fix available for this bug? DPDK 2.2 with Xen on 32-bit is broken now... If not, there will be no way to enable Xen for next Ubuntu LTS, which is very sad... I have a great Xen project planned for Ubuntu 16.04 + DPDK + Xen with DPDK Apps running on PV domUs! Thanks! Thiago
