Hi! I have been trying to get UML working in Ubuntu Lucid 64 bit system using various filesystems and kernels from e.g. uml.devloop.org.uk. Because after two days of attempts I could not get even a login prompt, I downloaded suitable kernel and fs for my netbook (eeepc 1000H). The result is even more disappointing: no error messages, just "Segmentation fault". The command line is ./kernel32-2.6.32.11 ubda=Ubuntu-LucidLynx-i386-root_fs Now I would be very happy to see _any_ kernel with _any_ filesystem in _any_ architecture to give me even a login prompt, is this possible?

There are many 64 bits UML guest working at the http://cloonix.net website. Cloonix-net is a framework that helps in managing virtual machines, both UML and KVM. The framework and guest filesystem for 64 bits machines have been tested on Fedora 13 64bits and Ubuntu 10.04 64bits. For UML machines, you can choose Debian sid 64bits or Fedora 13 64bits or Ubuntu 10.04 64bits. All machines are running kernel 2.6.35.

Is it true? Does it then make sense to still support it for server virtualisation, besides science projects? I'm working on UML images and a framework for managing UML instances for server hosting too, and am still considering if it's worth releasing., if unmaintained. Greets, Falk |

Hello, UML is in the current kernel and is working, I have never used the ska patch, it is not necessary, so it may not be maintained. I believe that the basic UML is maintained but KVM is taking the lead as kernel virtualisation solution. UML works well and must not be dismissed so easily. The cloonix-net is a totaly user tool, you never need to be root to use it, as a consequence, sockets are used to access to the UML or KVM emulated ethernet interfaces. As a matter of fact, the UML socket (a sun socket) is much more efficient than the KVM (qemu-kvm) socket (a stupid TCP socket that slows traffic when packets are too small). The consequence of this is that as long as the qemu socket network access is slow, I will use the UML machines for my own usage in cloonix. But for compilation or any other cpu usage, KVM with the virtio (para-virtualisation) devices is much faster than UML. UML is probably there to stay, and there may be debug usages where it is better than KVM.
