OpenVZ
In this guide provides instructions on setting up a basic virtual server using the OpenVZ Technology.
Installation
Emerge
Install the sys-kernel/openvz-sources package:
root #emerge --ask sys-kernel/openvz-sourcesKernel
Processor type and features --->
[*] Fair CPU scheduler
[*] VCPU scheduler support
File Systems --->
[*] Quota support
<M> VPS filesystem
<M> Virtuozzo Disk Quota support
[ ] Unloadable Virtuozzo Disk Quota module
[*] Per-user and per-group quota in Virtuozzo quota partitions
OpenVZ --->
[*] Virtual Environment support
<M> VE calls interface
[ ] Enable sysfs support in Virtual Environments
<M> VE networking
[*] VE netfiltering
<M> VE watchdog module
After you've built and installed the kernel (steps not covered in this article), update the boot loader and reboot to see if the kernel boots correctly.
Host environment
To maintain your virtual servers you need the sys-cluster/vzctl package which contains all necessary programs and many useful features:
root #emerge --ask sys-cluster/vzctlConfiguration
The vzctl packages has installed an init script called vz. It will help you to start/stop virtual servers on boot/shutdown:
root #rc-update add vz default
root #/etc/init.d/vz start
Creating a guest template
Template tarball
Since many hardware related commands are not available inside a virtual server, there has been a patched version of baselayout known as baselayout-vserver. However all required changes have been integrated into normal baselayout-2, eliminating the need for seperate vserver stages, profiles and baselayout. The only (temporary) drawback is that baselayout-2 is still considered to be in alpha stage and there are no stages with baselayout-2 available on the mirrors yet.
As soon as baselayout-2 is stable you can use a precompiled stage3/4 from one of our mirrors. In the meantime please download a stage3/4 from here.
Unfortunately vzctl does not understand bzip2 (yet?) and needs a different filename to recognize Gentoo as the distribution, so you have to convert the stage tarball.
Convert the stage tarball:
root #cd /vz/template/cache
root #bunzip2 stage4-<arch>-<version>.tar.bz2
root #mv stage4-tarball.tar gentoo-<arch>-<version>.tar
root #gzip gentoo-<arch>-<version>.tar
root #cd -
Create VPS
root #vzctl create <vpsid> --ostemplate gentoo-<arch>-<version>Do not use vpsids <=100, they are reserved.
Usage
Test the virtual server
You should be able to start and enter the vserver by using the commands below:
root #vzctl start <vpsid>
root #vzctl enter <vpsid>
root #ps axPID TTY STAT TIME COMMAND
