Re: [Vserver] Maximum guest on one host
I don't mean to hijack the thread here, but unification as a way to help his resource utilization, could someone please point me to a good resource for unification? I have searched the vserver wiki, but there doesn't really seem to be anything on how to setup and use unification. Also, does unification change the upgrade/maintenance process?

Re: [Vserver] snmp & vserver
Thanks, Actually, that's what I did; I replace 127.0.0.1 with the ip of the guest. But I fear that I will meet one time or another a program that needs 127.0.0.1. The problem with this solution is that it requires an instance of cacti inside each guests, which is not convenient for resources and management.

What I would be looking for is if the adding of an address generates a 'udev event' similar to discovering a new card. I don't think it should, but it might be doing that.

The parallel initialization is a dependency guided system; Could be that does not have all the rough edges smoothed out. I 'fixed' mine by building the required ethernet drivers into the kernel rather than let the system auto-load the modules. (Three nics, two pci, one usb) Now that is not a 'fix' of the problem - but a work-around to get my kernel to boot within a reasonable amount of time. Since this is only a personal-use machine, not a production machine; I just said: "good enough for now" and went on to more pressing issues here without really running down the prime cause.

I don't have my hands on your set-up - so I can't say what/how to make the changes to your configuration files, but that is the 'slow to initialize' ethernet nics problem area. Believe me, you do not want to plug in a usb-nic if you want a fast boot - it will eventually boot but you could swear the kernel hung while waiting.
