Aha, ok, sorry for my lack of knowledge here, but I assumed the environment
should be the same as in the host. Logical question, is it 'normal' that the
host has a+rw and the guests don't?

ATM I'm happily running 3 to 5 vservers, 3 of them replaced 2 actual
computers! Much less noise ;) and I could finally separate things. It's
running in a (I'm not sure if this is gentoo specific) multilib environment,
not pure 64bit but it al looks pretty solid, no real problems, the vservers
are doing their work nicely. IOW thanx guys! :)
