== Google Summer of Code Ideas == === Minimalistic Web Frontend === ''Userspace, php or similar'' Web Frontend or Framework to do basic administrational tasks like * creating and destroying guests * starting and stopping guests * monitor status and resources === libvirt Integration and Testing === ''Userspace, scripting, testing'' preliminary work exists, probably needs to be adapted to recent versions and integrated with the libvirt folks. === iptables proxy and policy daemon === ''Kernelside proxy, Userspace policy daemon'' Linux-VServer uses IP Isolation, so things like iptables cannot be allowed inside a guest without applying some sanity checks and general host policy. Part of this is a kernel side proxy mechanism, which will relay the netlink commands issued from e.g. iptables inside a guest to a policy daemon running on the host. The other part is the policy daemon which has to check the requests for plausibility, and if applicable implement them in a way which doesn't harm the host or other guests (e.g. on a separate chain). === hard limits for CFS scheduler === ''Kernel modification (target upstream)'' Linux-VServer implements a Token Bucket (TB) scheduler extension which sits ontop of the Linux scheduler able to limit the CPU resources on a per guest basis. Recent Linux provides a Completely Fair Scheduler (CFS) which is missing a hard limit feature, which should be implemented in way that mainline (kernel.org) can make use of it. [[Category:Ideas]]
