7.emerging your kernel:

#emerge vserver-sources

8.configuring your kernel
#cd /usr/src/linux
#make menuconfig

configure your kernel now!

Linux VServer --->
(Do not enable the legacy options)
[ ] Enable Legacy Kernel API
[ ] Enable Legacy Networking Kernel API
(Read help text)
[ ] Remap Source IP Address
[*] Enable COW Immutable Link Breaking
[ ] Enable Virtualized Guest Time
[*] Enable Proc Security
[*] Enable Hard CPU Limits
[*]   Avoid idle CPUs by skipping Time
[*]   Limit the IDLE task
Persistent Inode Tagging (UID24/GID24)  --->
[ ] Tag NFSD User Auth and Files
[*] Enable Inode Tag Propagation
[*] Honor Privacy Aspects of Guests
[ ] VServer Debugging Code

File systems  --->
<*> Reiserfs support
[*]   ReiserFS extended attributes

#make && make modules_install
#copy arch/i386/boot/bzimage /boot/myvserver-sources

Step 9 to 10 follow the gentoo quickie setup guide:

11. Update the portage and emerge the following packages for
preparation.

#emerge --sync
#emerge util-vserver - this is the main package!

12. Add the following to boot process and start the daemons.

# rc-update add vprocunhide default

# /etc/init.d/vprocunhide start

# rc-update add vserver.default default

# /etc/init.d/vserver.default start

13. Adding a level4 vserver and startup scripts

download the stage4 portage for the vserver setup

#wget hxxp://poepole.linux-vserver.org/~hollow/stages/stage4-i686-20070905.tar.bz2

then provide the following syntax after the download

vserver boyformat build \
-m template \
--context 0529 \
--hostname boyformat\
--interface eth0:192.168.0.1/24 \
--initstyle gentoo \
-- \
-d gentoo \
-t /path/to/stage4-arch-version.tar.bz2

# mkdir -p /etc/vservers/boyformat/apps/init

# echo "default" > /etc/vservers/boyformat/apps/init/mark
