[ovirt-users] OVN Configuration

2018-10-21 Thread Armond Kuehn 
High I've been trying for a couple months to setup an Ovirt Cluster with 
OVN/OVS implemented. I can make a network work on my home single server 
deployment but any time I create a vm on my hyperconverged setup the VM crashes 
stating it can't connect to the br:ex. (error messages aren't included because 
lab has 0 external connectivity). I assume this is due to nothing creating the 
OVN/OVS connections on each host in the manner that my single server does. I 
know there are ways to manage this such as ManageIQ but I haven't had any luck 
finding a good guide or walkthrough to get my systems to integrate those 
products. Does anyone know of where I could find one? Or willing to walk a 
dummy through it?

[ovirt-users] Re: high load on hosts

2018-10-21 Thread Donny Davis 
What is the workload from the VM? Is it an IO bound workload?

 I'm wondering how I can best limit the ability of VMs to overrun the

 servers, 10Gbe/SSDs, plenty of ram and CPU with only a hand full of light

 seeing load average on host node shoot up in to the 20-30s, how can a
 single "medium" vm cause host load to rise so high?

2018-10-21 Thread Jayme 
Yes I understand how virtualization works, but what I'm saying is that my
hosts each have 16 cores, 256gb ram, 10GBe networking and all SSD storage
with VMs allocation only a fraction of the available resources, yet high
load on a single VM with 2 cpus and 4gb ram allocated can cause the host
load to rise above 30. I'm trying to determine why one VM with limited
resources can cause the load on the host to go up so much.

[ovirt-users] Re: re-enabling networkmanager

2018-10-21 Thread Donny Davis 
Use the Ovirt engine to manage your networks. VDSM takes over at boot time,
and the only way for this to happen is if you use the engine

[ovirt-users] Re: Metrics Store installation - ansible playbook "deploy_cluster" - docker_image_availability

2018-10-21 Thread Shirly Radco 
Hi Markus,

Thank you for reporting this issue.
Can you please open a Bugzilla ticket on ovirt-engine-metrics with the
details you supplied here so I can better investigate it and communicate on
it?
Also, It will help other users if they hit the same issue.

Thanks in advance,
