[gate] Mask AVX2 to prevent 16.04 on 16.04 VMs boot crashes
16.04 on 16.04 VMs will crash (illegal instruction in raid6_avx21_gen_syndrome) on boot if the host has AVX2 and we pass that through. The issue seems to be the guest kernel sees presence of AVX2 so raid6 module makes use of it - though it's not enabled (different bits). Until this is resolved in the host hypervisor (kvm) and/or guest kernel, mask out AVX2 to prevent crashes in L1/L2 VMs. Change-Id: I0ca8edb8f62f9f2e96aa5e265bac631c346d0eac
