What's a quagga? (A distro?) Either use copy on write partition files, or else use hostfs to borrow the hosts's root ala: ./linux rootfstype=hostfs rw init=/bin/sh You can run dozens of instances that way, assuming you've got enough memory. (Default is 32 megs, change with the standard kernel command line argument ala "mem=128M", or feed it a ubd swap partition.) Also when using hostfs, keep in mind that even the root user within UML can't mknod or chown in a hostfs filesystem. They can't do anything the user running UML on the host couldn't do. But if you need to do that you can mount ramfs or tmpfs somewhere, or make an ext2 filesystem image and loopback mount it... > Regards, > Michael.- > > pd:restrictions for tun/tap interfaces? Use the hub daemon. http://prdownloads.sourceforge.net/user-mode-linux/uml_utilities_20040406.tar.bz2 http://user-mode-linux.sourceforge.net/networking.html#switch Give each client a random MACADDR on the command line (with the first byte 0 because UML will veto broadcast mac addresses, I.E. if (macaddr[0]&1) is set. Then it's the hub daemon's job to have an uplink to the host's network via tun/tap. Rob ------------------------------------------------------- This SF.Net email is sponsored by the JBoss Inc.
