VoIP in a virtualized environment with limited timing facilities. However,
OpenVZ makes use of a shared kernel which in my prior experience, does not
have the issues associated with fully virtualized technologies like VMWare,
KVM, Xen, Hyper-V, etc. Am I incorrect or is this issue specific to
Freeswitch (but apparently not so in use with Asterisk) ?

Maybe the errors are harmless? I have not actually pushed any traffic
through this installation yet, due to the errors.
