Hey guys,
linux-vserver is a pretty sweet implementation, as it introduces
virtually no latency since the vserver runs in a hacked up version of
chroot().
There are however some limitations with that approach. Security-wise,
it gives the attackers access to (almost) the whole range of
syscalls, which could be troubling in some environments. Also, in
terms of networking, you can't (to my knowledge) do per-vserver
iptables rules, and for your users to change any firewall settings
they will have to bug you for things like shaping and so on.
In VMware, you have the ability to take live snapshots, which you can
later clone, restore or clone for backups (even though if you want
better disk performance of your virtual appliance, its recommended to
disable snapshots). In vserver, you cant easily do that (you can
snapshot filesystems, a best).
That aside, it wont run anything else then Linux. It is also picky
about distros, since it needs some init modifications to boot properly.
Regards,
Alex

I ran WindowsXP/Centos/Solaris etc. in VMWare for a long time on

a dual
boot windows partition around for certain hardware that didn't work
well in
VMWare, and for BIOS upgrades (the only thing Windows is really
usefull,
although not required, for.) I am now interested in moving away
from vmware
because of the overhead. The ease of use of VMWare is only an
advantage
during the learning curve period of lesser friendly management
systems. In
the long run, I found that if the system overhead is high (ala
VMWare) I will
keep it running less and it will effect my efficiency.
If you are going to do other, linux, virtualization, I would like
to recommend
vserver. I have a P4 dev machine with 1GB RAM and I run 7 virtual
machines on
it simultaneously, 24/7. It runs a debian host and debian and
centos clients.
(On my home system I have even installed a Gentoo client under my
Debian
host.) Overhead is very low. It amazes my friends (and bosses).

To give context for my question - I've just bought a Dell desktop
based on
Intel Core 2 Duo and installed Debian Etch (amd64) on it,
A bit off topic but why try to install amd64 on an Intel chip? Why
not "Intel
IA-64"
