After working through some DNS problems I was able to install oVirt 4.4.1.1 and progress the engine deployment stops within the ansible scripts.  The system deploys the gluster domain, creates the engine, starts the engine, however it will never fully boot and complete the deployment.  Bringing up the console of the engine sets it into rescue mode.  I have attempted to set the appropriate variables in grub rescue  set root=(hd0,msdos1) set prefix=(hd0,msdos1)/boot/grub insmod normal And this will not boot the engine.  Is there a procedure to mount a CENTOS 8 rescue CD/ISO to troubleshoot this or is there a specific fix published for this problem?   The specific error I am seeing in the Engine Console is "attempt to read outside of HD0. I upgraded the ovirt engine appliance package to ovirt-engine-appliance-4.4-20200716090128.1.el8.x86_64 which produces the same result.  I have gotten this error deploying on both my Intel and AMD based servers.  any help is appreciated. thanks Andy
