Non-responsive vm's due to crashed host and hosted vm liveliness check fails
by clam2718＠gmail.com
Dear Community:
The local drive on a host running ovirt-node-ng-4.1.9 in a three node cluster failed. I have production JIRA and Postres running on it at the time, not in HA, just simple vm's. Storage is via NFS on a Synology NAS. Hosted Engine was on a different host, but JIRA and Postgres vm's showed nonresponsive. I tried different things but then stupidly thought that upgrading my Hosted Engine would reinitialize the vm's that were on the failed host. Update of HE seemed to go well (output below) but now my Hosted Engine, while up, fails the liveliness check and the web management console is unavailable. I cannot console into the HE from the host it is running on. Below are the results of my attempts to console into the Hosted Engine. Please help! I have search forums, lists and Google but have not been able to fix this. My coworkers and manager are anxious.
---
When I try "hosted-engine --console" after setting the console password I get
The engine VM is running on this host
Connected to domain HostedEngine
Escape character is ^]
_
The prompt is non-responsive except for the escape character key combo.
---
"virsh -r list" gives ID 3, Name: HostedEngine, State: running
"virsh -r console HostedEngine" gives
Connected to domain HostedEngine
Escape character is ^]
error: operation forbidden: read only access prevents virDomainOpenConsole
"virsh -r vncdisplay HostedEngine" gives "0:0" and returns me to prompt
---
I am SSHed into the host running my Hosted Engine from a CentOS7 minimal install with packages xorg-x11-server-Xorg, xorg-x11-xauth and xorg-x11-apps installed. The result of "grep -i X11Forwarding /etc/ssh/sshd_config" shows it set to "Yes".
I SSH into the host using "ssh -Y root(a)xxx.xxx.xxx.xxx" I am logged into the CentOS7 minimal install as root. I know root is poor practice but was trying to minimize anything that could be causing an issue.

Below are the results of my attempt to update Hosted Engine (slightly redacted to remove personal info):

User agent for Ovirt 4.2
by Jim Kusznir
Hi:
I haven't managed to find the new / current repo/source for the ovirt guest
agent for the 4.2 upgrade. All my VMs now say that they need the agent.
Googles keep referring me to old / broke / non-existent repos. Where do I
find the 4.2 agent (or does the 4.2 agent even exist?)
Thanks!

OVA export/import
by RabidCicada
All,
I recently tried to used the OVA export/import functionality. It
seems I misunderstood the intentions. I expected OVA export/import to
be reciprocal functionalities. I expected what we export as OVA to be
importable as OVA in ovirt.
What I have found is the following:
* It seems OVA export does export an OVA, though the format is not
spec compliant
* We use 'disk/' in the HostResource xml field instead of '/disk/'
for example in the ovf.
* It seems OVA import is intended specifically for VMWare OVA's?
* I thought I read about export domains being deprecated, and
incorrectly assumed the recently added OVA export/import was to make
things better for one off import/export.
Can anyone clarify the following:
* Is OVA import really just VMWare OVA's?
* Are we really not spec compliant with the OVA/OVF format as my
example above shows? OR do I misunderstand something?
* After spending my time yesterday, I recall now that the deprecation
of export domain is in favor of detaching and re-attaching ANY data
domain.
* What is the purpose of our OVA export if we ourselves indeed cannot
import our own OVA? Or can you tell me how we import our own if I'm
wrong.
Please feel free to overshare details :), as any context will help
prevent more confusion on my part.

Ovirt-Hosted-Engine-Install-Purge Ansible Script Snippet
by RabidCicada
All,
I put together a full purge ansible script for CentOS. I figured I'd
share it here. I ran into many issues with spurious failures of
installs when I would try to reinstall ovirt on CentOS after having
"removed" it.
I was developing an automated install of our own software along with
ovirt but along the way I had to reinstall on the same box numerous
times. Initially I'd get spurious failures from leftover cruft that
would get in the way. I eventually found
this:https://www.ovirt.org/documentation/how-to/hosted-engine/#recoving-f...
and then crafted my own ansible purge script.
It uses ovirts own engine cleanup script first if it exists, then
fully cleans every other thing that can affect it.
Tested on CentOS, probably will work on other distros without too much
trouble. Hopefully someone saves themselves some grief

VM created is reachable from only oVirt node
by sweettriplek＠gmail.com
VM running with centos is not reaching to any other network other than oVirt node. I tried to apply no network filer, clean-filter while creating vNIC interfaces but no luck.
Setup configurations:
- oVirt Engine and Node running on different machines
- OVirt running on cent OS
Please help me to resolve this issue, thanks in advance.

guests crashing during live migration(NUMA config issue)
by Balg, Andreas
Hello,
during updates of our physical nodes running ovirt 4.2.3 I had to live-
migrate all VMs to evacuate them from the hosts. This caused roughly
10% of guests to end up crashed /shutdown after live migration.
Errors in the Logs are:
2018-05-31T15:15:51.273805Z qemu-kvm: warning: All CPU(s) up to maxcpus
