[PVE-User] Join cluster first time - problem

[lord_Niedzwiedz]

         I do it first time.

I create cluster ok on host1:

pvecm create klaster1
pvecm status

And on host2 i try:

pvecm add tomas.komandor.pl

detected the following error(s):
* this host already contains virtual guests
Check if node may join a cluster failed!

what i do wrong ??
