You better virtualize it and pray no one breaches the hypervisor. ;)
In all seriousness, you would definitely want to prevent one user from taking out the whole box. As much as we all trust one another, there is always room for an 'oops, I rm -rf'd /usr/bin...' to happen.
Great idea though, I'd definitely be interested!
- jacquesm 17y agoThat's a good suggestion, but I don't have much experience with hypervisors, how much overhead do you think that would give ?
- easp 17y agoThe overhead of a hypervisor is pretty low. VPS hosts will divide a 16GB 4-8 core machine into 40 pieces with Xen and each slice performs pretty well (provided that not all of them are running CPU intensive jobs at once. The main overhead is that each virtual machine has its own kernel memory, file cache, etc. There are other virtualization approaches that use a shared kernel, and which may be able to use a single copy of common shared libraries across partitions (not sure about this last part though). FreeBSD jails or OpenVZ on Linux fall into this category.
