New subject: Some major problems after 4.2 upgrade, could really use some assistance

Thursday, 11 January 2018

This is becoming critical for me, does anyone have any ideas or
recommendations on what I can do to recover access to hosted VM?  As of
right now I have three hosts that are fully updated, they have the 4.2 repo
and a full yum update was performed on them, there are no new updates to
apply.  The hosted engine had updates as well as a full and complete
engine-setup, but did not return after being shut down.  There must be some
way I can get the engine running again?  Please

 The hosts have all ready been fully updated with 4.2 packages
though.

 ex.

 ovirt-host.x86_64
 4.2.0-1.el7.centos                               @ovirt-4.2
 ovirt-host-dependencies.x86_64
  4.2.0-1.el7.centos                               @ovirt-4.2
 ovirt-host-deploy.noarch
  1.7.0-1.el7.centos                               @ovirt-4.2
 ovirt-hosted-engine-ha.noarch
 2.2.2-1.el7.centos                               @ovirt-4.2
 ovirt-hosted-engine-setup.noarch
  2.2.3-1.el7.centos                               @ovirt-4.2
