Re: [ovirt-users] HEVM root reset?

Hi, the simplest approach is: hosted-engine --set-maintenance --mode=global hosted-engine --vm-shutdown # wait for it hosted-engine --vm-start-paused hosted-engine --add-console-password # open a vnc or spice console pointing to the VM # when ready virsh -c qemu://$(hostname)/system resume HostedEngine # quickly stop the boot process from the vnc or spice console # force root password as for a regular el7 system # shutdown the engine VM hosted-engine --set-maintenance --mode=none On Sat, Oct 28, 2017 at 11:25 PM, Chas Ecomm <chashock(a)speakfree.net&gt; wrote: > > TIA for any guidance you can give me here, I’m in a bit of a pickle and > have spent many hours reading many posts and blogs that don’t seem to get me > where I need to be, and despite my gut feeling that someone has had to have > dealt with this somewhere else, my google-fu is failing me in finding anyone > who has dealt with this particular problem. > > > > My issue: > > > > I’ve inherited a 4.1 hosted-engine setup.
