Hello Michal,
The Live Migration fails. Events does not show any information but just
mentioning migration failed. This happens even when we put the host into
maintenance. VMs do not migrate and host fails to move into maintenance
mode.
Attempted to upgrade the Hosts, but failed, no reasons attached.
I am a bit lost at this stage. Should we check for some more information
in some logs? If yes, where do we find the logs?

Hello Michal,
Guest tools are working and getting all details about guest vm as needed.
But one thing I didn't understand. What is the relationship between
virtioserial driver and oVirt Guest Service? Without virtio serial
driver, guest services does not start.
Also, how do we install memory baloon driver?
Tomorrow morning, I will post about Live Migration events after I
attempt it.

Hello Michal,
Thanks for quick feed back.
Windows Guests Agents - Where do I download them from? Not getting
the proper links. Or is to a part of virt-drivers that we use during
installation.
Hi Anantha,
it’s part of ovirt-guest-tools. See
http://lists.ovirt.org/pipermail/users/2016-May/039779.html
Live migration failure - These are pretty busy VMs if not big. The
event does not show any specific message but just as migration
failed. Is the reason logged somewhere? Please share the log
location so that I can check & share the log for meaningful message
and proper screen shots.
There should be more details in the events at the bottom of the
webadmin page (just make it a bit bigger it may not be te last message)
If they are busy VMs then you may have issues migrating them. There
is some simple tuning available and it may help. You can increase the
maximum downtime in VM properties dialog (500ms by default, you can
go up to whatever is feasible for your VM, seconds, tens of seconds)
Bandwidth is limited to work on 1Gb network, if you have 10Gb
availabl you can also tune /etc/vdsm.conf on each host and increase
the maximum bandwidth 10 times
Thanks,
michal

Hi,
We have just installed oVirt 3.6 on 3 hosts with storage volumes
on Fibre Channel storage box. Every thing is working fine except
the following.
1. We have created 15 Virtual Machines all VM with Windows Server
2012 R2 OS. VM properties does not report the Operating System nor
it shows the IP and FQDN in the Admin Portal. There is always an
exclamation mark that reports about OS being different from the
template and timezone issues. We have changed the timezone to
Indian Standard Time in both VM and Host, same result continues.
We have installed Windows Gues Tools, same result continues.
Screen shot is below.
you doesn’t seem to run the guest agent. Make sure the service is
started and works, then you’ll see IPs and more detailed info about
each guest, and exclamation marks should go away
<VMs.PNG>
2. When we manually tried to migrate the VMs from one host to
another one, the migration gets initiated, but will eventually fail.
Any specific setting missing here or is it a bug.
are they big or busy VMs? What does it fail on? There should be a
menaingful message even if it’s just a timeout
Note:
All hosts are installed with CentOS 7.2 minimal installation oVirt
node is installed and activated.
We do not have a DNS in our environment. We have to do with IPs.
as long as engine works with FQDN it’s ok
We are yet to apply the 3.6.6 patch on Engine and Nodes.
that may help with some of the issues above, so please try to do that
Thanks,
michal
We are running a stand alone engine, not a Hosted Engine.
