Depends on your system.If you have an embedded system, it may mot mount it at all. If your system uses an initrd or initramfs, it probably gets done by the startup script in there. If neither of those happen, it's usually done by /etc/rc.sysinit or similar, unless your system uses systemd for startup in which case you're going to be digging around to figure out where it does it. pgp_BE6WO2OUr.pgp Description: PGP signature ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies

If in fact /sys and /proc aren't getting mounted, a *whole lot* of stuff won't work (for instance, /bin/ps will break, as will /bin/df. I'm reasonably sure that most udev implementations need /sys around, so I'm surprised that you're getting booted at all... pgp4Ud2Vjl5gS.pgp Description: PGP signature ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies

Hi John, Have you set "NAT" under Devices --> Network Adapters? This is just a guess and I am not sure whether this serves your purpose or not.

It's amazing how much can go wrong during a Linux boot and you still get a login prompt... >but when I typed 'ifconfig' command , it reports no such file : > /proc/net/dev . Is the /proc filesystem mounted? What kernel are you trying to boot, a distro kernel or a self-compiled one? pgpww4uUtI1RT.pgp Description: PGP signature ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
