Well, I was thinking about what the snapshot feature of qemu could bring me.
In fact, I thought about the following solutions: - qemu (or whatever other virtualization system) - chroot (or specifically dchroot in Debian) and remote telnet or ssh access - UML Advantages of every solution: - qemu virtualizes a complete machine, which means installation of an OS is possible and it is pretty safe (security-wise) to setup - chroot is fast to run and pretty safe - UML is fast to run and pretty safe Problems of every solution: - qemu is slow, and a lot of virtual machines at the same time on the same machine will slow it down and use too much memory, I think (I'm talking about 10 people «playing» at the same time). Using only a text-mode virtual machine may probably help, though - chroot does not allow much and may take time to setup correctly - UML is difficult to setup, and needs a kernel patch (even on 2.6?) to work > Paul -- Jerome Warnier <[EMAIL PROTECTED]> BeezNest _______________________________________________ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel
