hostd.log-entry: RecordOp ASSIGN: guest.disk, 16

I am using VMware Server 2.02 (64Bit) on Ubuntu 8.0.4. LTS Server (64Bit). I get lots of Messages in hostd.log like

[2012-02-27 17:07:37.083 'PropertyProvider' 1096591696 verbose] RecordOp ASSIGN: guest.disk, 16

Do i have to care about this messages? What is the meaning of this message?

I converted a real Windows XP Machine to VMware-Fusion on MAC and moved the resulting vmdk-File to VMware-Server. The VM seems to start and run without problems.
