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

11 Jan 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

Hi,
yes, you need to upgrade the hosts. Just take the
ovirt-hosted-engine-ha and ovirt-hosted-engine-setup packages from
ovirt 4.2 repositories.

How do I upgrade the hosted engine packages when I can't reach it or do
you
mean upgrade the hosts if so how exactly do I do that. As for the
missing VM
it appears that the disk image is there but it's missing XML file I
have no
idea why or how to recreate it.

Hi,
you hit one known issue we already have fixes for (4.1 hosts with 4.2
engine):
https://gerrit.ovirt.org/#/q/status:open+project:ovirt-hoste
d-engine-ha+branch:v2.1.z+topic:ovf_42_for_41
...
You can try hotfixing it by upgrading hosted engine packages to 4.2 or
applying the patches manually and installing python-lxml.
I am not sure what happened to your other VM.
Best regards

I performed Ovirt 4.2 upgrade on a 3 host cluster with NFS shared
storage.
The shared storage is mounted from one of the hosts.
I upgraded the hosted engine first, downloading the 4.2 rpm, doing a

it powered down the hosted VM but it never came back up.  I was
unable
to
start it.
I proceeded to upgrade the three hosts, ovirt 4.2 rpm and a full yum
update.
I also rebooted each of the three hosts.
After some time the hosts did come back and almost all of the VMs are
running again and seem to be working ok with the exception of two:
1. The hosted VM still will not start, I've tried everything I can

of.
2. A VM that I know existed is not running and does not appear to
exist,
I
have no idea where it is or how to start it.
1. Hosted engine
From one of the hosts I get a weird error trying to start it:
# hosted-engine --vm-start
Command VM.getStats with args {'vmID':
'4013c829-c9d7-4b72-90d5-6fe58137504c'} failed:
(code=1, message=Virtual machine does not exist: {'vmId':
u'4013c829-c9d7-4b72-90d5-6fe58137504c'})
From the two other hosts I do not get the same error as above,
sometimes
it
appears to start but --vm-status shows errors such as:  Engine status
: {"reason": "failed liveliness check", "health": "bad", "vm": "up",
"detail": "Up"}
Seeing these errors in syslog:
Jan 11 01:06:30 host0 libvirtd: 2018-01-11 05:06:30.473+0000: 1910:

4967-a1e5-fbe47c0cd705':
Bad file descriptor
2. Missing VM.  virsh -r list on each host does not show the VM at
all.
I
know it existed and is important.  The log on one of the hosts even
shows
that it started it recently then stopped in 10 or so minutes later:
Jan 10 18:47:17 host3 systemd-machined: New machine qemu-9-Berna.
Jan 10 18:47:17 host3 systemd: Started Virtual Machine qemu-9-Berna.
Jan 10 18:47:17 host3 systemd: Starting Virtual Machine qemu-9-Berna.
Jan 10 18:54:45 host3 systemd-machined: Machine qemu-9-Berna
terminated.
How can I find out the status of the "Berna" VM and get it running
again?
Thanks so much!
