Running UML on my Linode
Is it possible to run a UML-kernel within my Linode account?

I haven't begun attempting to do anything with UML yet but it is something that I am looking into and just wanted to be sure that it would work before attempting it.. Thanks for the quick response.
I plan to host a web site on my Linode, and it just occurred to me that it might be really useful to run nested UML. This is only a half-baked idea, but see what you think:
I will run two UMLs on my Linode: one for production and one for development. Only the production UML will be attached to the outside world via eth0.
To make changes to my website, I copy the contents from the production UML to the development UML, and make changes only in the development UML. After they're sufficiently tested, then I somehow make eth0 be attached to the development UML instead of production, effectively swapping them. Now the development UML is "live", and I rename it to be the production UML.
The benefit of this scheme is that it won't be possible to trash my web site by mistake while making any changes. If I totally blow it (or if apt-get upgrade does something unexpected), then I can just recopy the production UML to the development UML and try again. Only when I'm fully satisfied that it's working on the development UML do I make it live.
What do you think? Is anyone doing this?

Even though it is possible, in general it is not a good idea as least on linode.
Due to the limited diskspace and memory available it can make things run very slow, espically on the lower end linodes.
