updates ran with no problems

I work with VMWare and used free ESXI for home for a while now but have been interested in Xen for a few months now. When XCP-ng was available I soon downloaded and installed and are looking forward to furture releases. It is replacing the free ESXI I have at home and with XOC its is a great setup. I want to get freenas working as a VM with passthrough but struggling at the moment.
