We observed several crashes on MariaDB databases when using Xen PVH mode. After switching back to Xen PV, all fine. The strange thing is that on application servers it works just fine (speeded up compilation times by 30%).

Gentoo Linux with kernel 4.1, Xen 4.6.0/4.6.1.

More details reported on Gentoo / MariaDB bug trackers:

Best regards,
