But I stuck with the download process. No matter what browser I use, they interpret the XML data after clicking on download and I just see plain text. Does anybody know a plugin or option to get the "real" xml-code?
I'll take PCD any day. You just deploy the PCD app from OVF file, discover your ESXi hosts (assuming your ESXi licenses allows NFS mounting), deploy the VM OVAs, upload install ISO only to PCD SFTP store, no need to add it to each ESXI datastore, create new install cluster in PCD and lastly in PCD create new install task. You fill out the information, i.e. IP address, usernames, DNS, NTP only once in PCD for all nodes that are being installed.
