JUST CANT UNDERSTAND WHY OVIRT DOESNT HAVE A WEB-GUI FOR EDITING ,REMOVING UNWANTED STORAGE DOMAINS I configured openfiler as my iscsi storage and while i am able to connect to it ....i wanted to change the IP address of the connecting IP to one of the logical networks which i disignated as a STORAGE role. This is a nightmare changing this and i have to set hosts in maintenence mode and delete the datacenter , is there any other way ?

Memory ballooning not working on RHEV 4.1?
by Joseph Chapman 16 Apr '17

16 Apr '17

Hello all, I have a RHEV 4.1 host running Windows 10 VMs. I have installed the balloon driver on the VMs (RHEV guest tools), and enabled memory ballooning on the cluster using RHEV-M. On the VMs, I have set the system memory to Memory Size: 4GB, Maximum Memory: 16GB. While I can manually hot plug memory, I am not seeing additional memory being automatically allocated to the VMs during a SQL workload. The documentation for RHEV 4.1 is not clear on whether or not this automatic ballooning is functional (earlier documentation suggests that it is functional only by use of an API). I am new to RHEV and would appreciate some help troubleshooting this. Please let me know if there's any additional information I should provide. I messaged this mailing list on suggestion from someone in the IRC. I hope this is in-bounds. Thanks for your time! -- Joseph Chapman http://fjchapman.tumblr.com +1 828 777 0751

I thought about : 1+2 : ovirtmgmt (bond) 3+4 : iSCSI (multipath) 5 : VM and Display 6 : Migration What do you think about this configuration ? Is it a bad idea to set VM and display on the same network interface ? Do ovirtmgmt need high bandwidth ? In terms of bandwidth, is it a bad idea to have one single NIC for Migration ?

cleanup old recovery backup
by eric stam 14 Apr '17

14 Apr '17

Good morning, Just a question. When I do an upgrade of a hosted-engine by the "hosted-engine --upgarde-appliance" command the procedure will automatically make a backup for recovery. Is there a way to remove an old backup, without finding out yourself which files user used and which not (and hooping you will not remove a wrong one). -- Gr. Eric Stam *Mob*.: 06-50278119

spice folder sharing

Hi all, Is there a native way to enable spice sharing like described there: https://www.spice-space.org/docs/manual/manual.chunked/ar01s10.html I guess such a hook is very simple to write. -- Nathanaël Blanchet Supervision réseau Pôle Infrastrutures Informatiques 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr

Hosted engine setup shooting dirty pool
by Jamie Lawrence 13 Apr '17

13 Apr '17

Or at least, refusing to mount a dirty pool. I have 4.1 set up, configured and functional, currently wired up with two VM hosts and three Gluster hosts. It is configured with a (temporary) NFS data storage domain, with the end-goal being two data domains on Gluster; one for the hosted engine, one for other VMs. The issue is that `hosted-engine` sees any gluster volumes offered as dirty. (I have been creating them via the command line right before attempting the hosted-engine migration; there is nothing in them at that stage.) I *think* what is happening is that ovirt-engine notices a newly created volume and has its way with the volume (visible in the GUI; the volume appears in the list), and the hosted-engine installer becomes upset about that. What I don’t know is what to do about it. Relevant log lines below. The installer almost sounds like it is asking me to remove the UUID-directory and whatnot, but I’m pretty sure that’s just going to leave me with two problems instead of fixing the first one. I’ve considered attempting to wire this together in the DB, which also seems like a great way to break things. I’ve even thought of using a Gluster installation that Ovirt knows nothing about, mainly as an experiment to see if it would even work, but decided it doesn’t matter, because I can’t deploy in that state anyway and it doesn’t actually get me any closer to getting this working. I noticed several bugs in the tracker seemingly related, but the bulk of those were for past versions and I saw nothing that seemed actionable from my end in the others. So, can anyone spare a clue as to what is going wrong, and what to do about that? -j - - - - ovirt-hosted-engine-setup.log - - - - 2017-04-11 16:14:39 DEBUG otopi.plugins.gr_he_setup.storage.storage
