Maybe I should try these too...

I'm really undecided what to do with my current OpenVZ installations.

My machines are old amd64 without CPU virtualisation capabilities, which
rules out KVM.  That also means Qemu, VirtualBox etc. would be too slow,
and wasteful of resources by running a separate instance of the kernel
for each guest.  I think Xen would be awkward for the same reason,
though I'm keeping it in mind as an option.

The shared kernel between guests is openvz's particular strength.  I'm
under the impression that LXC doesn't yet provide the isolation of
superuser privileges (due to procfs?) that I need.


Also I still suffer from issues in 2.6.32 (and 2.6.26) on my main
production box that I haven't been able to reproduce on any spare
machine;  I haven't been able to test for these problems in Debian 3.x
kernels due to the lack of openvz, so the best I can do is probably try
one of these rhel kernels.


In the long term maybe openvz will come back for the next Debian release
after Wheezy (then maybe in Wheezy backports), or maybe LXC will get the
extra features I need.  Or perhaps by then I can afford shiny new
hardware with CPU support for virtualisation. :)

Same here, I run these on top of mdraid.
