Error creating a storage domain (On Cisco UCS Only)
by nico.kruger＠darkmatter.ae
Hi Guys,
I am trying to install a new cluster... I currently have a 9 node and two 6 node oVirt Clusters... (these were installed on 4.1 and upgraded to 4.2)
So i want to build a new cluster, which is working fine on this HP notebook i use for testing (using single node gluster deployment)
But when i try install this on my production servers which are Cisco UCS servers i keep getting this error:
[ ERROR ] Error: Fault reason is "Operation Failed". Fault detail is "[Error creating a storage domain]". HTTP response code is 400.
[ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "Fault reason is \"Operation Failed\". Fault detail is \"[Error creating a storage domain]\". HTTP response code is 400."}
This happens during storage creation after the hosted-engine is built and after gluster has been deployed (error happens for both single and 3 replica deployments)
I just cant see how an install on one type of server is successful but not on the UCS servers (which i am running my other ovirt clusters on)
BTW i dont think the issue is related to Gluster Storage Create as i tried using NFS and Local storage and get the same error (on UCS server only)
I am using the ovirt-node-ng-installer-4.2.0-2019011406.el7.iso install ISO

qemu-img info showed iscsi/FC lun size 0
by jingjie.jiang＠oracle.com
Hi,
Based on oVirt 4.3.0, I have data domain from FC lun, then I create new vm on the disk from FC data domain.
After VM was created. According to qemu-img info, the disk size is 0.
# qemu-img info /rhev/data-center/mnt/blockSD/eaa6f641-6b36-4c1d-bf99-6ba77df3156f/images/8d3b455b-1da4-49f3-ba57-8cda64aa9dc9/949fa315-3934-4038-85f2-08aec52c1e2b

file format: raw
virtual size: 10G (10737418240 bytes)
disk size: 0
I tried on iscsi and same result.
Is the behaviour expected?
Thanks,

oVirt Performance (Horrific)
by drew.rash＠gmail.com
Hi everybody, my coworker and I have some decent hardware that would make great single servers, and then we through in a 10gb switch with 2x10gbps cards in 4 boxes.
We have 2 excellent boxes - super micro board (disabled speed step) with 14 core intel i9's 7940x's, 128 GB ram (3200), 1tb m.2 samsung 870 evo's, 1tb ssd samsung, 1 8TB WD Gold, 1 6TB WD gold.
Then we have 2 boxes (1 with 8 core i7-9700k, 1 with 6 core i7-8700) 128GB ram in one, 64GB ram in the other all 3000MHz with the same 1tb ssd,6tb wd gold, 8tb wd gold drives as the other boxes and 10gbps cards.
Our problem is performance. We used the slower boxes for KVM(libvirt) and FreeNAS at first which was great performance wise. Then we bought the new super micro boxes and converted to oVirt + Gluster and did some basic write test using dd writing zero's to files from 1GB up to 50GB and were happy with the numbers writing directly to the gluster. But then we stuck a windows VM on it and turned it on...I'll stop there..because turning it on stopped any performance testing. This thing blew goat cheese. It was so slow the oVirt guest agent doesn't even start along with MS SQL server engine sometimes and other errors.
So naturally, we removed the gluster from the equation. We took one of the 8TB WD Gold drives, made it a linux NFS share and gave it to oVirt to put VM's on as an NFS Domain. Just a single drive. Migrated the disk with the fresh windows 10 installation to it configured as VirtIO-SCSI, and booted the vm with 16GB ram, 8:1:1 cpu's. To our surprise it still blew. Just ran a winsat disk -drive c: for example purposes and the spice viewer repeatedly freezing, had the resource monitor open watching the 10,000ms disk response times with results...results were I rebooted because the results disappeared I didn't run it as administrator. And opening a command prompt is painful, the disk is still in use The task manager has no words on it. Disk is writing like 1MBps. command prompt finally showed up and looked blank with the cursor offset with no words anywhere.
So the reboot took .. Well turning off took 2 minutes. Booting took 6 minutes 30 seconds ish. Logging in: 1m+
So 9-10 minutes to reboot and log back in a fresh windows install. Then 2 minutes to open a command prompt, task manager and resource monitor.
During the write test disk i/o on the vm was less than 8, from the graph looks like 6MBps. Network traffic is like 20Mbps average, cpu is near zero, a couple spikes up to 30MBps on the disk. I ran this same thing on my disk and it finished in <1m. Ran it on the vm...still running after 30 minutes. I'll wait for the results to post them here. Ok It's been 30 minutes and it's still writing. I don't see the writes in the resource monitor, windows is doing a bunch of random app updates or something with candy crush on a fresh install and, ok so I hit enter a bunch of times on the prompt and it moved down to a flush-seq...and now it shows up in the resource monitor doing something again...I just ran this on my pc and it finished in less than a minute... whatever it's doing it's almost running at 1MB/s
I think something went wrong because it only shows like 2 minutes passing at any test and then a total of 37 minutes. And at no time did the windows resource graphs or any of the oVirt node system graphs show more than like 6MB/s and definitely not 50 or 1GBps... flat out lies here.

I even ran it again and it had the exact same results. So I'll try copying a file from a 1gbps network location with an ssd to this pc. It's a 4GB CentOS7 ISO to the desktop. It said 20MB/s then up to 90MB/s...then it dropped after doing a couple gigs. 2.25 gigs to go and it's going at 2.7MB/s with some fluctuations up to 5MB. So to drive this home at the same time... I copied the file off the same server to another server with ssd disks and it ran at 100MB/s which is what I'd expect over a 1gbps network.
All this said, we do have an ssd gluster 2+1 arbiter (which seemed fastest when we tested different variations) on the 1TB ssd's. I was able to do reads from the array inside a VM at 550MB/s which is expected for an ssd. We did dd writing zero's and got about 550MB/s also from the ovirt node. But inside a VM the best we get is around ~10MB/s writing.
Basically done the same testing using windows server 2016, boot terrible, opening applications terrible. But with sql server running off the ssd gluster I can read at 550MB/s but writing is horrific somewhere around 2-10MB/s.
Latency between the nodes with ping is 100us ish. The hardware should be able to do 200MB/s HDD's, 550MB/s SSD's but it doesn't. And it's evident in every writing scenario inside a vm. Migrating VM's is also at this speed.
Gluster healing seems to run faster, we've seen it conusme 7-9 Gbps. So I feel this is an oVirt issue and not gluster. Especially since all the tests above are the same when using an NFS mount on the box running the VM in oVirt.
Please guide me. I can post pictures and such if needed, logs whatever. Just ask.

Suggestions on adding 1000 or more networks to an engine/hosts
by Brian Wilson
So we have a use case where our engines will will be hosting development sandbox clusters. We need to have upwards of 1000 networks on some of these.
I understand there is no theoretical limit to the number of networks does any body have a good reliable way of instantiating all of these networks.
We have been using ansible for POCs and doing 100 Networks have not had a problem getting them on there however when upping the number to many more it begins to take longer and longer between each one and eventually timed iout and only got to 1567
Example Task we are using for this:
tasks:
- name: Add More Networks
ovirt_network:
auth: "{{ ovirt_auth }}"
data_center: "{{ pcloud_name }}"
name: "{{ pcloud_name }}-{{ item }}"
state: present
label: uplink
vlan_tag: "{{ item }}"
clusters:
- name: "{{ ovirt_cluster }}"
assigned: yes
required: no
display: no
migration: no
gluster: no
with_sequence: start=1551 end=2500
What are some better ways of bulk additions of networks? Would the API provide a better solution so as to sorta bulk cache them then initiate the save?

Ovirt Node 4.3 Gluster Install adding bricks
by pollard＠tx.net
Sorry if this seems simple, but trial and error is how I learn. So the basics. I installed Node 4.3 on 3 hosts, and was following the setup for self-hosted engine. The setup fails when detecting peers and indicates that they are already part of a cluster. So i restart the install and choose the install engine on single node with Gluster. I now have all three nodes connected to ovirt engine, however my trouble is I am not understanding how to add the disk of the two nodes to the glusterFS. I also have some extra disks on my primary node I want to add. I believe it is as follows but I dont want to mess this up.
Under Compute >> Hosts >> $HOSTNAME
Select Storage Devices
Select Disk in my case sde
Then create brick?
If this is the case Do I add it to a LV if so which one engine,data or vmstore?
Do I repeat this for each hosts?
I can duplicate the engine, data and vmstore on each one, but that will still leave me with two disks on each node without assignment
If anyone can help that would be great.
Thank you.

Unable to make Single Sign on working on Windows 7 Guest
by Felipe Herrera Martinez
On the case I'll be able to create an installer, what is the name of the Application need to be there, in order to ovirt detects that Ovirt Guest agent is installed?
I have created an installer adding OvirtGuestService files and the Product Name to be shown, a part of the command line post installs..
I have tried with "ovirt-guest-agent" and "Ovirt guest agent" Names for the application installed on Windows 7 guest and even both are presented on ovirt VM Applications tab,
on any case LogonVDScommand appears.
There is other option to make it work now?
Thanks in advance,
Felipe

Subject: Need VM run once api
Hi Experts,
We are integrating ovirt with our internal cloud.
Here we installed cloudinit in vm and then converted vm to template. We
deploy template with initial run parameter Hostname, IP Address, Gateway
and DNS.
but when we power ON initial, run parameter is not getting pushed to
inside the vm. But its working when we power on VM using run once option
on Ovirt portal.
I believe we need to power ON vm using run once API, but we are not able
get this API.
Can some one help on this.
I got reply on this query last time but unfortunately mail got deleted.
Thanks & Regards
Chandrahasa S
