I find there are other advantages to VServer. We use both KVM and
VServer in our environment on hefty hardware. Not only do the lower
requirements make a difference on highly virtualized systems (nothing
like seeing dozens of small servers running in 8MB of RAM) but there are
interesting advantages that can be gained from the shared file system
and the ability to remount portions of the host file system into the
guests.
So we certainly see the need for both. The VServer team is incredibly
talented and helpful but also very small so we are keeping our eyes
closely on LXC. I'm just a little concerned about the userland tools.
I had heard there was talk if util-vserver supporting LXC but I do not
know how far that integration has gotten - John
