SSH into guest VM
by 03ce007＠gmail.com
I have self-hosted-engine (4.2) deployed successfully on cento (7.4) server.
The physical server has 'ovirt' as hostname and the self-hosted engineVM deployed
and running on it has 'engine.ovirt' as fdqn.
I can successfully create new VM using the oVirt.vm-infra example playbook. But what other config/var i need to add in them so that I can ssh into this new VM. Some example, tips, hints would be helpful.
Thank you.

Bad volume specification
by Bryan Sockel
Hi,
I am having to rebuild my ovirt instance for a couple of reasons. I have
setup a temporary ovirt portal to migrate my setup to while i rebuild my
production portal.
I have run int a couple of VM's that will no longer start.
Everything that i am seeing is identical to this article -
https://access.redhat.com/solutions/2423391
VM devel-build is down with error. Exit message: Bad volume specification

Currently running version 4.2.3.5-1
Is there anyway to recover the image, or even just be able to mount the
drive to another vm to extract data.
Thank You

ovirt guest agent epel 6 and rhevm in the name
by Gianluca Cecchi
Hello,
I have updated one test environment to 4.2 (it was in 4.1.9)
I have a guest in Oracle Linux 6 and epel 6 repo enabled.
After powering down and start the VM, I saw the exclamation mark regarding
ovirt-guest-agent latest version needed.
On the VM the process was dead and I took the time of updatng it
from ovirt-guest-agent-1.0.12-4.el6.noarch
to ovirt-guest-agent-1.0.13-2.el6.noarch
and start the agent.
All seems ok; no exclamation mark now and I see the ip addresses of the
guest in 4.2 web admin gui.
But in log of ovirt-guest-agent I see:
MainThread::ERROR::2018-05-28
14:34:55,711::ovirt-guest-agent::140::root::Unhandled exception in oVirt

Anything to be done at my side at guest/host configuration level?
Thanks,

CentOS7 Install Failure to Shutdown
by Matthew Wimpelberg
I have ovirt 4.2.3.5-1.el7.centos installed and am unable to cleanly reboot
the host machine. The only way I can reboot is to press and hold the power
button which causes an unclean shutdown of the engine vm. I can upload
logs if necessary I'm just not sure where to upload them to.

Fwd: External ceph storage

Indeed, you right. Will setup the gws while waiting for a maybe future
native ceph connection, which in my oppinion would bring a lot of power to
oVirt.
