Just curious (I only have experience with virtuozzo from the client standpoint not the server admin standpoint) -- when increasing memory or disk space for a given vps account, what would cause it to suddenly "come crashing down". That doesn't sound very stable :eek: and seems rather contrary to the virtozzo concept as presented in their ads where they for example show accounts being shifted between hardware with ease.
There are variables that rely on other variables. If they are not scaled properly, you can cause serious problems. I dont have the list infront of me to give you an exact example, but it gets rather tedious.
Most companies dont simply modify the hd space, or allocated ram, etc. They use templates, to be sure that each customer gets the same thing for the same price.
However when adjusting using templates, there may be some software upgrades as well, now the liability is being moved toward the company if something goes wrong. To avoid any problems, the method mentioned is just the safest for both the company, and the customers.
Coming to Virtuozzo's stability... you can knock over a stable building by removing a few important bricks. This is not to say that it is not stable! It is infact quite stable, however like anything else, the configuration can make all the difference in the world!
