UML is built using custom kernel configuration and runs on 64 bit AMD. Everything works well if if run up to 3 virtual networks (12 nodes), but when i start fourth virtual network it's third virtual machine always dies with something, that is reported on host logs as: [71175.799976] linux[621] general protection ip:7f72d6110a1c sp:6027b760 error:0 in libc-2.9.so[7f72d60dc000+167000] I tried with 2.6.31.2 and 2.6.32-rc8 kernels for guest machines. Host runs 2.6.31.2 kernel. Will be glad to provide you with more info and help with tracking that problem down.
