Solaris containers are descendants from FreeBSD jails: they provide different userland namespaces(*) on top of a shared OS kernel. Hardware virtualization on the other hand provides different hardware namespaces(*) on top of a shared hypervisor. These are basically sandboxing methods with different levels of isolation and performance. I would not expect that jails/containers introduce new challenges with respect to missing interrupts.
