Re: oVirt + Gluster
by Strahil 23 Sep '19

23 Sep '19

Recently both oVirt node and Hypervisor have moved to gluster v6 (although I have moved a little bit earlier). For me v6 of Gluster is quite stable and if you dig up really nice , you will be able to even setup 'gtop' which gives great info. Ovirt is quite well integrated with gluster - doing health checks ,provide monitoring, allow creating additional gluster volumes and many more. Still, if you have FC available - it should be way easier to setup and tune. Docs are one of the weak stuff , but you can always check RHV (4.0+) and Oracle docs - as oVirt is upstream of RedHat's and Oracle's Virtualization.

Hey All, Seeing GlusterFS up to version 7, do any of the oVirt versions support anything higher then 3.X? Or is Gluster not the preferred distributed file system choice for oVirt? -- Thx, TK.

On the opposite - ovirt supports up to v6 of gluster and in cockpit, you can setup your hyperconverged setup (on gluster) abd your hosted engine ontop.

Linked Clones?
by marzoccafabio＠gmail.com 22 Sep '19

22 Sep '19

Hi, I am approaching and studying oVirt in order to propose the solution to a customer as a replacement for a commercial solution they have now. They only need Desktop virtualization. Sorry for the silly question, but I can't find a way to deploy a VM (template) to users as a "linked-clone", meaning that the users' image still refers to the original image but modification are written (and afterwards read) from a new location. This technique is called Copy-on-write. Can this be achieved with oVirt? Fabio

CentOS 7.7 has been released: note it's not supported for oVirt 4.2
by Sandro Bonazzola 19 Sep '19

19 Sep '19

CentOS 7.7 has been released this week. Please note that CentOS 7.7 is not supported for oVirt 4.2 and older releases. If you want to upgrade to CentOS 7.7 please upgrade to oVirt 4.3 too. If you don't plan to upgrade to oVirt 4.3 please be sure your yum repo files points to http://mirror.centos.org/centos/7.6.1810/ instead of http://mirror.centos.org/centos/7/. The http://mirror.centos.org/centos/7/ URL is now pointing to http://mirror.centos.org/centos/7.7.1908/ so yum upgrade will bring you 7.7 content which may break your 4.2 installation. Thanks, -- Sandro Bonazzola MANAGER, SOFTWARE ENGINEERING, EMEA R&D RHV Red Hat EMEA <https://www.redhat.com/> sbonazzo(a)redhat.com <https://www.redhat.com/>*Red Hat respects your work life balance.

At least KVM can do that. If I understood correctly, you want a base disk for multiple VMs and the delta should be stored in separate disk, right? I am using VDO (with gluster) under my storage, so any duplicate data is deduplicated (and if yiu enable compression - compressed) by VDO. Have you thought about VDO - it works with almost any block storage ?Of course both technology will reduce the I/O performance compared to raw storage. Also, let's see if actually oVirt has such option...

how to add devices to a qemu config.xml of a virtual machine
by pascal＠butterflyit.com 19 Sep '19

Hi, I would like to be able to share a local folder with my remote desktop hosted by ovirt. Looking everywhere it seems that what is needed is to have spice-webdavd installed on the guest and have qemu set with this channel org.spice-space.webdav.0 I don't see in the web admin interface any ways to add those channels, but found on the web an addon which could maybe work vdsm-hook-qemucmdline but can't find a package compiled for the latest version and how to install it Also I noticed in the latest version of ovirt 4.3.5 there are 2 flags: Enable SPICE file transfer Enable SPICE clipboard copy and paste But that doesn't seem to change anything Any help appreciated

no hosted engine deploy while adding new host (oVirt 4.3.5)
by lars.stolpe＠bvg.de 18 Sep '19

18 Sep '19

I tryed to add a new host to my oVirt environment. I remember a checkbox whether the engine HA wil depoyed or not in oVirt 4.1. Now the environmentist oVirt 4.3.5. In the add host dialog windows I cant find that option anymore. In edit window after host installation ther ist also no hosted engine tab. hosted-engine --deploy don't ask, if it is an additional host (like it used to in 4.1), so it will install a new engine instead of depoying the existing engine. Is there a new way of depoying the engine HA to additional hosts?

I created a new ISO domain type via storage and pointed to an NFS share on the new storage, however it does not behave as I anticipated (I cannot see ISO's when creating new VM's) > > I suspect I missed a step - how are new ISO domains added to a cluster? > > Mark > > *** > Mark Steele > CIO / VP Technical Operations | TelVue Corporation > TelVue - We Share Your Vision > 16000 Horizon Way, Suite 100 | Mt.

ovirt-imagio-proxy upload speed slow

I am working on integrating a backup solution for our ovirt environment and having issues with the time it takes to backup the VM's. This backup solution is simply taking a snapshot and making a clone and backing the clone up to a backup server. A VM that is 100 gig takes 52 minutes to back up. The same VM doing a file backup using the same product, and bypassing their rhv plugin, takes 14 minutes. So the throughput is there but the ovirt imageio-proxy process seems to be what manages how images are uploaded and is officially my bottle neck. Load is not high on the engine or kvm hosts. I had bumped up the Upload image size from 100MB to 10gig weeks ago and that didn't seem to help. [root@blah-lab-engine ~]# engine-config -a |grep Upload UploadImageChunkSizeKB: 10240000 version: general [root@bgl-vms-engine ~]# rpm -qa |grep ovirt-image ovirt-imageio-proxy-1.4.6-1.el7.noarch ovirt-imageio-common-1.4.6-1.el7.x86_64 ovirt-imageio-proxy-setup-1.4.6-1.el7.noarch I have seen bugs reported to redhat about this but I am running above the affected releases. engine software is 4.2.8.2-1.el7 Any idea what we can tweak to open up this bottleneck?
