Few Questions on New Install
by Talk Jesus
Greetings,
Just installed Ovirt:
Software Version:4.2.0.2-1.el7.centos
How Do I:
- add a subnet of IPv4 to assign to VMs
- download (or import) basic Linux templates like Centos 7, Ubuntu 16 even
if using minimal iso
- import from SolusVM based KVM nodes
Does oVirt support bulk IPv4 assignment to VMs? If I wish to assign say a
full /26 subnet of IPv4 to VM #1, is this a one click option?
Thank you. I read the docs, but everything is a bit confusing for me.

Re: [ovirt-users] Live migration of VM(0 downtime) while Hypervisor goes down in ovirt
by Luca 'remix_tj' Lorenzetto
What you're looking at is called fault tolerance in other hypervisors.
As far as i know, ovirt doesn't implement such solution.
But if your system doesn't support failure recovery done by high
availability options, you should take in account to revise your application
architecture if you want to keep running on ovirt.

We need a continuous availability of VM's in our production setup. If the
hypervisor goes down due to any hardware failure or work load then VM's
above hypervisor will reboot and started on available hypervisors. This is
normally happening but it disrupting VM's. Can you suggest a solution in
this case? Can we achieve this challenge using glusterfs?
Thanks & Regards

I think there are two parts to achieving this:
1. Have a script that migrates VMs off a specific host. This should be easy
to write using the Python/Ruby/Java SDK, Ansible or using REST directly.
2. Having this script run as a service when a host shuts down, in the right
order - well before libvirt and VDSM shut down, and would be fast enough
not to be terminated by systemd.
This is a bit more challenging.
Who's shutting down the hypervisor? (Or perhaps it is shutdown externally,

Y.
Using glusterfs is it possible? Then how?

VM backups - Bacchus
by Niyazi Elvan
Dear Friends,
It has been a while I could not have time to work on Bacchus. This weekend
I created an ansible playbook to replace the installation procedure.
You simply download installer.yml and settings.yml files from git repo and
run the installer as "ansible-playbook installer.yml" Please check it at
https://github.com/openbacchus/bacchus . I recommend you to run the
installer on a fresh VM, which has no MySQL DB or previous installation.
Hope this helps to more people and please let me know about your ideas.
ps. Regarding oVirt 4.2, I had a chance to look at it and tried the new
domain type "Backup Domain". This is really cool feature and I am planning
to implement the support in Bacchus. Hopefully, CBT will show up soon and
we will have a better world :)
King Regards,

Maximum time node can be offline.
by Thomas Letherby
Hello all,
Is there a maximum length of time an Ovirt Node 4.2 based host can be
offline in a cluster before it would have issues when powered back on?
The reason I ask is in my lab I currently have a three node cluster that
works really well, however a lot of the time I only actually need the
resources of one host, so to save power I'd like to keep the other two
offline until needed.
I can always script them to boot once a week or so if I need to.
Thanks,
Thomas

Virt-viewer not working over VPN
by Vincent Royer
Hi, I asked this on the virt-viewer list, but it appears to be dead, so my
apologies if this isn't the right place for this question.
When I access my vm's locally using virt-viewer on windows clients,
everything works fine, spice or vnc.
When I access the same vm's remotely over a site-to-site VPN (setup between
the two firewalls), it fails with an error: unable to connect to libvirt
with uri: [none]. Similarly I cannot connect in a browser-based vnc
session (cannot connect to host).
I can resolve the DNS of the server from my remote client (domain override
in the firewall pointing to the DNS server locally) and everything else I
do seems completely unaware of the vpn link (SSH, RDP, etc). For example
connecting to https://ovirt-enginr.mydomain.com works as expected. The
only function not working remotely is virt-viewer.
Any clues would be appreciated!

Ok. I will reproduce and collect logs.
Thanx,

if you provide the engine.log file we might have a look at it.

Hi,
I have observed this logged at host when the issue occurs:
VDSM command GetStoragePoolInfoVDS failed: Connection reset by peer
or
VDSM host.domain command GetStatsVDS failed: Connection reset by peer
At engine logs have not been able to correlate.
Are you hosting Windows 2016 server and Windows 10 VMs?
The weird is that I have same setup on other clusters with no issues.
Thanx,
Alex

Hi all,
I have a cluster with 3 nodes, using ovirt 4.1 in a self hosted setup on
top glusterfs.
On some VMs (especially one Windows server 2016 64bit with 500 GB of disk).
Guest agents are installed at VMs. i almost always observe that during the
backup of the VM the VM is rendered unresponsive (dashboard shows a
question mark at the VM status and VM does not respond to ping or to
anything).
For scheduled backups I use:
https://github.com/wefixit-AT/oVirtBackup
The script does the following:
1. snapshot VM (this is done ok without any failure)
2. Clone snapshot (this steps renders the VM unresponsive)
3. Export Clone
4. Delete clone
5. Delete snapshot
Do you have any similar experience? Any suggestions to address this?
I have never seen such issue with hosted Linux VMs.
The cluster has enough storage to accommodate the clone.
Thanx,
Alex

Cannot Remove Disk
by Donny Davis
Ovirt 4.2 has been humming away quite nicely for me in the last few months,
and now I am hitting an issue when try to touch any api call that has to do
with a specific disk. This disk resides on a hyperconverged DC, and none of
the other disks seem to be affected. Here is the error thrown.
2018-02-08 10:13:20,005-05 ERROR
[org.ovirt.engine.core.bll.storage.disk.RemoveDiskCommand] (default
task-22) [7b48d1ec-53a7-497a-af8e-938f30a321cf] Error during

5a497956-0380-021e-0025-00000000035e
Any ideas what can be done to fix this?
