OS: Oracle Linux 7.8 (unbreakable kernel)
Using Oracle Linux Virtualization Manager: Software Version:4.3.6.6-1.0.9.el7

Since I am running all of it on one physical machine I opted to install the ovirt-engine using the accept defaults option.

When I try to start a noVNC console I see this in the messages file:
May 26 16:49:12 lfg-kvm saslpasswd2: Could not find keytab file: /etc/qemu/krb5.tab: No such file or directory

I have checked the following:
[root@lfg-kvm ~]#  engine-config -g WebSocketProxy
WebSocketProxy: lfg-kvm.corp.lfg.com:6100 version: general
[root@lfg-kvm ~]# engine-config -g SpiceProxyDefault
SpiceProxyDefault: http://lfg-kvm.corp.lfg.com:6100 version: general

This is a brand new install.

I also am unable to get a VNC console up and running.  I have tried with an Ubuntu VM running on my MAC where I installed virt-manager.  The viewer comes up for a second says it cannot connect and then shutsdown.

Anyone have any clue?
