I am having the same problem as Nikos I am trying to implement a vnet-enabled service jail on FreeBSD 8.0 HEAD. I have thoroughly studied the "Network stack virtualization" document written by Marko. I received troubleshooting help over several days last from Julian Elischer when I raised the issue in this thread on the freebsd-net list. I am running a GENERIC kernel on amd64, with the additional options vimage, netgraph, ng_ether, and ng_eiface. I successfully applied the patch Bjoern provided: http://people.freebsd.org/~bz/20090901-10-vimage-jailed_no_vnet.diff I tested with this patch, and also the lines in the other patch Bjoern provided that are not in HEAD: http://people.freebsd.org/~bz/20090906-01-V_llatbl.diff i.e., +#include <sys/jail.h> + CURVNET_RESTORE(); + CURVNET_SET_QUIET(TD_TO_VNET(curthread)); +vnet_lltable_init(const void *unused __unused) +{ + + /* Manually do what SLIST_HEAD_INITIALIZER would do. */ + V_lltables.slh_first = NULL; +} + +VNET_SYSINIT(vnet_lltable_init, SI_SUB_PSEUDO, SI_ORDER_ANY, vnet_lltable_init, + NULL); Trying to apply a ruleset after mounting devfs in a jail, I get: devfs -m /jail/j/ns/dev rule -s 8 applyset devfs rule: ioctl DEVFSIO_SAPPLY: No such process Attempting to apply a default route to the ngeth0 interface bound to the jail, I get: route: writing to routing socket: Network is unreachable add net default: gateway 00:23:54:08:2b:f7: Network is unreachable netstat -r gives: netstat: kvm not available: /dev/mem: Permission denied Routing tables rt_tables: symbol not in namelist I have /dev/mem mounted in the jail. I've seen reference to mem not being accessible in the jail, in some of the discussions on running x-server in the jail. Julian mentioned that it looked like I need to make /dev/mem accessible in the jail. I do not know how to do that; it also seems that if I had a routing socket, I could live without reading memory for netstat output. I understand each jail has its own FIB. I thought jails opened a routing socket during their creation by default. I need to add a default route to use the jail: vimage ns route add default -link 00:0a:0b:0c:2b:f7 But no combination I've tried succeeds. Any help appreciated :->
