[ovirt-users] SPICE and Windows 10

[Colin Coe]

Hi all

We've just updated our dev environment from 4.1 to RHV 4.3 and found that
while a lot better, Windows 10 under SPICE still isn't great.

We're running dual screen VMs at 2560x1440 resolution.  The Windows login
screen is particularly bad although once logged in it gets better but not
great.  The benchmark here is Windows 10 vs Windows 7 VMs.

We've gone into settings / advanced and set "configure for best
performance".  Latest RHV tools (4.3-6) are installed.  We've also created
"/etc/ovirt-engine/osinfo.conf.d/20-overload.properties" containing:
os.windows_10.devices.display.vramMultiplier.value = 4
os.windows_10x64.devices.display.vramMultiplier.value = 4

When we set the multiplier to 8, as recommended in another thread,
ovirt-engine fails to restart.

I know there have been a few threads on this but I'd like to ask what is
the advice for RHV/oVirt 4.3 to make Windows 10 faster?  VDI on RHV makes
up an important part of what we do and RDP, VNC, etc are not an option.

Thanks

[ovirt-users] Group Consumer on Quota not trickling down to Users in Group?

[Brian T]

Good morning all,

I have a problem with how Groups are handled with Quotas. Currently, when you 
assign a Group to a Quota, it does not make all the Users in that Group a 
Consumer in that Quota. As the documentation states, one would have to add each 
individual User in that Quota.

Is this the intended design? I figure, much like how Groups are handled with 
other oVirt functions, that the Users in a Group assigned to a Quota should 
also inherit being a Consumer in that Quota.

Thank you.

[ovirt-users] [Feedback Needed] oVirt metrics store

[Shirly Radco]

Hi,

In the latest oVirt 4.3.z and 4.2.z releases we have simplified the metrics
store installation immensely and updated it to be based on OpenShift 3.11,
with Elasticsearch and Kibana 5.

The oVirt metrics store provides monitoring for the oVirt hosts and vms,
for both metrics and logs with pre-built example dashboards and self
service visualizations in Kibana.

5 steps for installing oVirt metrics store:
1. Update variables files
2. Run 1st ansible playbook -> creates the vms
3. Run 2nd ansible playbook -> deploys the metrics store on the created vms
4. Run 3rd ansible playbook -> configures the data collectors on the oVirt
hosts and engine
4. Load example dashboards to Kibana

In addition, we have replaced Fluentd with Rsyslog in 4.3.z hosts, for
better performance.

I invite you to try it out and give us feedback.

[ovirt-users] Donating hardware to the oVirt project - a great opportunity to contribute

[Evgheni Dereveanchin]

Hi everyone,

My name is Evgheni and I'm in charge of the infrastructure used by oVirt to
host the code, test it and serve packages to users. Currently we heavily
rely on our PHX data center [1] for these tasks. It consists of several
dozen bare metal servers that work as hypervisors, storage servers and bare
metal CI hosts. We use them quite effectively yet the amount of workload is
always growing so now is a good time to ask our community for help. If you
happen to have physical servers or VMs that could be used as part of oVirt
infra - please let us know. We created a page [2] describing hardware specs
that would allow us make the infra more stable and grow its capacity.

If you have any other ideas or input about the oVirt infra - feel free to
reach out to me or start a discussion on the Infra list [3].

Regards,
Evgheni

[ovirt-users] Re: enabling vPMU for virtual machine

[Jarosław Prokopowski]

Ok, so I found it myself:

1. Edit VM
2. Show Advanced options and go to Hosts tab
3. Set the VM to run on specific host
3. Enable "Pass-Through Host CPU" option - this is the magic
