Installing Plesk 8 onto Virtuozzo 3

[gmc2k2]

Hi everybody,

I setup a server with virtuozzo based on fc4 which is up and running. Then i setup a vps from an fc4 os template. The vps is also up and running fine.
Now i tried to install plesk8 on this vps and failed with following error message

[root@vz]# vzctl create 201 --config vps.plesk8.fc4 --pkgset fedora-core-4
Inconsistent VPS creation usage: unable to create VPS based on EZ template fedora-core-4-x86 by means of fedora-core-4

What am I doing wrong. Does someone have an idea.

Thanks for reading

Chris
