Hi Jeff, i changed the priority of the host /dev/net/tun to 777 and it didn't solve my problem. I noticed that one error message while booting is:
modprobe: FATAL: Could not load /lib/modules/2.6.24/modules.dep: No such file or directory Might that be the problem? Here is the result of dmesg on the guest OS: Linux version 2.6.24 ([EMAIL PROTECTED]) (gcc version 4.1.2 20070626 (Red Hat 4.1.2-14)) #1 Tue May 20 04:22:49 EDT 2008 On node 0 totalpages: 38454 Normal zone: 300 pages used for memmap Normal zone: 0 pages reserved Normal zone: 38154 pages, LIFO batch:7 Movable zone: 0 pages used for memmap Built 1 zonelists in Zone order, mobility grouping on.
