Just yesterday I had a brief talk with Herbert from vserver. He
mentioned that it should be ok to use different routing tables in
each vserver instance. If this works out then I would like to know if
vserver is a viable alternative. Vserver is very low overhead. One of
the problems that I had with UML is the high (soft-)IRQ load.
this produces permanent context switches and no work gets done. (if
you start 1000 instances that is!) :)
Can somebody test what happens if you start many instances in openVZ
and vserver?
I hope our dev server is up and living soon again.
best,
a.

Hello,
in openvz usuall all ebtables and iptables modules are supported
in the
0 instance. modules that can be used inside of virtuall instances
have
to be prepared for this. but this shouldn't be a problem for your
setup,
so i guess the problem may be somewhere else.
As fare as I remember there have been some promlems with the
development
versions of openVZ. With the stable version for kernel 2.6.18
everything
worked fine.
Except, the ebtables module oopsed when applying more than 25
rules !! Because
I wanted to configure virtual networks with up to 100 nodes this was a
problem. The mentioned patch solved this problem.
