<snip>I am thinking of putting the CentOS iso out and then booting the
VM into it just to poke around the file system. Otherwise my other
option is to just clone a twin VM on another server and then just
change the networking IPs/hostname. Anybody have any other ideas as to
how to debug this problem?
So I booted off the CentOS-7-x86_64-DVD-1511.iso and everything looks
just fine:

So the CentOS DVD iso in linux rescue mode shows that everything is
there and can be mounted. I guess that means somehow either grub itself
is corrupted or one of the boot images. So is there a way for me to
generate a new initrd while booted in linux resuce mode or will
re-installing grub help? How would I attempt re-installing grub while
booted in linux rescue mode?
