Changes
Update to allow Plesk VPN install to recognize kernel release
Make sure that the container's hostname (plesk.example.com) is resolving correctly to the container's IP address (127.1.2.3). You can also add the corresponding record to /etc/hosts as a workaround.
Due to how the Plesk VPN package install script works, it uses a regex on the output of "uname -r" to determine the kernel release to assure you have a minimum version of Virtuozzo (version 021stab025). So what you can do is get your version with "uname -r", and set the VE release name to fit the regex. For example:
<pre>
# uname -r
2.6.18-194.26.1.el5.028stab079.2
# echo "2.6.18-194stab079.2" > /proc/sys/kernel/virt_osrelease
# vzctl restart 11
</pre>
Then, go to http://www.parallels.com/download/plesk8/ and download the appropriate autoinstaller or the appropriate RPM. In this case, [http://download1.parallels.com/Plesk/Plesk8.1/CentOS4.3/psa_installer_v3.1.0_build061201.02_os_CentOS_4.3_i386 CentOS] 4.3.
