It turns out that the bug is due to the Xen kernel.
Basically you need to set "hwcap 1 nosegneg" in /etc/ld.so.conf.d/xen.conf

I am only recording this here because I just spent a frustrating number of hours when hitting the same bug -- and perhaps this can help someone else out in the same situation.
Additionally you probably want to also upgrade the kernel as well.
