Subject Re: new installation--ssvm won't start
Date Mon, 12 May 2014 22:40:19 GMT
I was able to complete the installation on Friday.  Two things I did
differently that were not mentioned in the quick start guide were to
disable requiretty in /etc/sudoers and to set up NFSv4 correctly (i.e. set
up a global root directory with fsid=0).  I'm not sure how much impact the
sudoers configuration had on my problem but I'm pretty sure the NFS setup
was the main issue.
