ovirt 4.2 gluster configuration
by Edoardo Mazza 08 Mar '18

08 Mar '18

Hi all, Scenario: 3 nodes each with 3 interfaces: 1 for management, 1 for gluster, 1 for VMs Management interface has it own name and its own ip (es. name = ov1, ip= 192.168.1.1/24), the same is for gluster interface which has its own name and its own ip (es. name = gluster1, ip= 192.168.2.1/24). When configuring bricks from Ovirt Management tools I get the error: "no uuid for the name ov1". Network for gluster communication has been defined on network/interface gluster1. What's wrong with this configuration? Thanks in advance. Edoardo

Pre-snapshot scripts to run before live snapshot
by Gianluca Cecchi 08 Mar '18

08 Mar '18

Hello, this thread last year (started by me... ;-) was very useful in different aspects involved http://lists.ovirt.org/pipermail/users/2017-March/080322.html We did cover memory save or not and fsfreeze automatically done by guest agent if installed inside the VM. What about pre-snapshot scripts/operations to run inside guest, to have application consistency? Eg if I have a database inside the VM and I have scripted my backup job involving live-snapshot (eg with the backup.py utility of the thread) Can I leverage this kind of functionality with the oVirt guest agent? Or is it mandatory to consider a remote connection to the VM (via ssh or what for windows?) and execute the script/command/bat file? What are you curently doing in this respect? Thanks, Gianluca

Tunable parameters in ovirt engine
by Hari Prasanth Loganathan 08 Mar '18

08 Mar '18

Hi Team, *Description of problem:* I am trying to achieve 1000 concurrent request to oVirt. What are the tunable parameters to achieve this? I tried to perform the benchmarking for ovirt engine using Apache benchmark using the same SSO token. ab -n 1000 -c 500 -k -H "accept: application/json" -H "Authorization: Bearer SSOTOKEN" https://172.30.56.70/ovirt-engine/ <https://172.30.56.70/ovirt-engine/api/vms/5440271b-afb3-48bb-9ff1-076fc07eb…> When the number of concurrent request is 500, we are getting more than 100 failures with the following error, SSL read failed (1) - closing connection 139620982339352:error: NOTE: It is scaling for concurrent request below 500. I used the profiler to get the memory and CPU and it seems very less, PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 30413 ovirt 20 0 4226664 882396 6776 S 126.0 23.0 27:48.53 java Configuration of the machine in which Ovirt is deployed : RAM - 4GB, Hard disk - 100GB, core processor - 2, OS - Cent7.x. In which 2GB is allocated to oVirt. Version-Release number of selected component (if applicable): 4.2.2 How reproducible: If the number of concurrent requests are above 500, we are easily facing this issue. *Actual results:* SSL read failed (1) - closing connection 139620982339352:error: *Expected results:* Request success.

Hi, is there any way to power off VM from VM portal (4.2.1.7)? I can't find "power off" button, just "shutdown".

Fibre Channel Protocol (FCP)
by maoz zadok 08 Mar '18

08 Mar '18

Hello All, I connected existing data center with NFS storage domain to a new Fiber-Channel storage domain according to the following guide, and I have three questions. https://www.ovirt.org/documentation/install-guide/chap-Configuring_Storage/ 1. why does the storage domain asks me to "Use Host"? - does it mean that if this host is down there is no access to the FC storage or the next available host elected to manage the FC storage? - does it mean that all the traffic to my storage is routed via the selected host? - what is the best practice, do I need to split the workload to other hosts as well by letting each host manage one small LUN instead of letting one host manage all LUNs or one big LUN? 2. is it possible to set the newly created fiber-channel storage(data domain) as master? 3. can I easily migrate all VM disks to the FC storage instead of the NFS? Thank you!

Unable to start VM after upgrade vom 4.1.9 to 4.2.1 - NPE

Hello, we have upgrade one of our oVirt engines to 4.2.1 (from 4.1.9) and afterwards all nodes too. The cluster compatibility level has been set to 4.2.

New oVirt blog - Your Container Volumes Served By oVirt
by Yaniv Kaul 07 Mar '18

07 Mar '18

When running a virtualization workload on oVirt, a VM disk is 'natively' a disk somewhere on your network-storage. Entering containers world, on Kubernetes(k8s) or OpenShift, there are many options specifically because the workload can be totally stateless, i.e they are stored on a host supplied disk and can be removed when the container is terminated. The more interesting case is *stateful workloads* i.e apps that persist data (think DBs, web servers/services, etc). k8s/OpenShift designed an API to dynamically provision the container storage (volume in k8s terminology). In this post I want to cover how oVirt can provide volumes for containers running on k8s/OpenShift cluster. Read more @ https://ovirt.org/blog/2018/02/your-container-volumes-served-by-ovirt/

Re: [ovirt-users] Troubleshooting VM SSO on Windows 10 (ovirt 4.2.1)
by Cristian Mammoli 07 Mar '18

07 Mar '18

Anyone??? Hi, I'm trying to setup sso on Windows 10, vm is domain joined, has agent installed and credential provider registered.Of course I setup an AD domain and the vm has sso enabled Whenever I log to the user portal and open a VM I'm presented with the login screen and nothing happens, it's like the engine doesn't send the command to autologin. In the agent logs there's nothing interesting but the communication between the engine and the agent is ok: for example the command to lock-screen on console close runs and works: Dummy-2::INFO::2018-03-01 09:01:39,124::ovirtagentlogic::322::root::Received an external command: lock-screen...

Unremovable disks created through the API
by Richard W.M. Jones 06 Mar '18

06 Mar '18

I've been playing with disk uploads through the API. As a result I now have lots of disks in the states "Paused by System" and "Paused by User". They are not attached to any VM, and I'm logged in as admin@internal, but there seems to be no way to use them. Even worse I've now run out of space so can't do anything else. How can I remove them? Screenshot: http://oirase.annexia.org/tmp/ovirt.png It's a pretty recent engine: ovirt-engine-4.2.2.2-0.0.master.20180225172203.gitd7cf125.el7.centos.noarch Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones Read my programming and virtualization blog: http://rwmj.wordpress.com virt-df lists disk usage of guests without needing to install any software inside the virtual machine.
