I haven't tested this myself, but apparently Arch works fine[1]
on OpenVZ if the host kernel is up-to-date. The installation
instructions don't seem to contain any OpenVZ specific steps,
so probably they're already compiling their glibc using the
broadest compatibility settings.

Moreover, the OpenVZ developers seem to be keen to backporting
features[2] required to run modern distributions, which makes
sense when you consider that their 3.10 based product is still
not ready.

Maybe we can make this work after all?
