Be sure you are not also running KVM, VMware, or any other VM
software. At this writing, only one virtualization platform can run at
a time.
LXC is not a virtualization platform (because it doesn't run
multiple kernels on one CPU). So your VirtualBox freeze-ups are
probably not
I have been using Rsnapshot (which is a thin wrapper around
rsync). I run Rsnapshot on the host, and thus, back up all my LXC
containers at once.
More about my rsnapshot setup can be found here:

You have not provided enough information to do a scientific
analysis. How many users is not very many? What kind of web-apps
will they be using under Plone? How much database and/or file access
will there be?
Generally speaking, I would suggest more RAM. It's cheap and can

Hi,

As a quick test, try setting it to this and see if it works:

the conflict with your physical device.)

I have had good luck with ext4 on multi-terabyte systems the last 3

When there are only one bridge on the system or the bridges are not
connected together, this option is pointless and we can set the delay to
'0'. That makes the port to be enabled instantaneously, hence the
container can access the network immediately after the start.
As previously posted,
Serge,
Could you please elaborate on this comment?
(Of course, the containers must be on a different subnet)
Do you mean a TCP/IP subnet? If so, why does this limitation exist?
I would like to use nested LXC containers for reselling CPU, disk,

above, or else to manually apply the patch and compile it yourself.

There is a behavior in the Linux kernel which can cause a bridge

This happens when bridging

However, I'm new to the LXC source and would like some input and

maybe even contribute a patch, but I'd like some feedback first.

/I tried the python script, it just works fine./
Q1: How does the kill -INT init method affect running processes,
especially MySQL and other databases that may need to shutdown
gracefully to avoid data corruption?
I believe that the child processes (incl. mysqld, apache, etc.)
in this bug is, like
your script, simply working around that fact.

Here's mine: Commercially selling raw CPU, RAM, and disk resources

customers, as a VAR.
