To share a device you need a multiplexer which has access to the physical device (and drives it) and provide a virtual device for each of the clients. One possible solution would be to grant one L4Linux instance access to the physical device and setup a virtual network connection between the two instances. Then you can e.g. use iptables to setup forwarding and NAT to route traffic from the second instance. > I would like also to switch between the two L4Linux shell, because in > Qemu only one shell is accessible.

You assign 1GB to the machine but only hand 64M to L4Linux (of which 32M are taken by the ramdisk).
