name of virtual machine and hostname
by nicola gentile 28 Jan '15

28 Jan '15

Good morning, I would like to ask you an information. After I have installed ovirt, I have created a pool of vm with name like centos-?? (from 1 to 20) and then ovirt generated 20 vm with name centos-1, centos-2, centos-3 etc. etc. The problem is when the vm starts the hostname is not the same of the vm name in ovirt but is the same name of the template. Is it possible to make sure that the name of vm and the hostname is identical? Best regard Nicola Gentile

ovirt 3.5 rc2 unable to mount cd on running VM
by Gianluca Cecchi 01 Dec '14

01 Dec '14

Hello, installed a CentOS 6.5 x86_64 vm from iso (create VM and then run once connecting CD iso). System reboot several times and power on from web admin gui and all seems ok. At a certain point I upload guest-tools iso to my engine for future windows VMs. Taken ovirt-guest-tools-3.5_5.iso and try to mount it In engine the downloaded file seems ok and I can loop mount it for test.

Sizing the master storage domain
by Nicolas Ecarnot 19 Nov '14

19 Nov '14

Hi, I know Itamar explained that the notion of master storage domain will disappear in some releases. But now, with a 3.4 I'm installing, I was wondering : - on my other oVirt setups, I started with one big (iSCSI) LUN, which is the master, and stored as many VMs I could - when space came to miss, I added another LUN, the another... - when I have to do some maintenance (grow, disable, other...) on a LUN, I can move my VM disks amongst the normal storage domains. When Empty, I can switch them off, add others, and so on The only one I can not play with is the master one. I came to think that I had no benefice storing anything on the master storage domain, and use only the normal storage domains. And then, I came to think I had no reason to dedicate a huge LUN for the master. Ok, but according to you, what is the minimum reasonable size for a master storage domain? -- Nicolas Ecarnot

GlusterFS Distributed Replicate HA with KeepAlived
by Punit Dambiwal 06 Nov '14

06 Nov '14

Hi, I have 4 node GlusterFS Distributed Replicate volume...the same 4 host node i am using for compute purpose....now i want to make it HA....so if any host goes down .....VM will not pause and it will migrate to another available node... 1. Can any one have any document or reference to do this with keepalived... 2. I have one more node as spare...so if any host goes down and can not come up again because of any HW failure...i can add it...but i didn't find any way to add these bricks to volume...?? Thanks, Punit

[Users] connecting to oVirt/RHEV VMs through proxy and the oVirt API
by i iordanov 31 Oct '14

31 Oct '14

Hello, My apologies for cross-posting, but this discussion concerns both mailing lists, I think. In Opaque, I recently started setting the proxy property of SpiceSession from a console file, as is done in remote-viewer, in order to support installations where the nodes are not "visible" from the point of view of the client. However, then I remembered that I have not seen the proxy property being available through the oVirt/RHEV API. I looked at the latest remote-viewer code, and I looked through the oVirt/RHEV API documentation, and indeed, I see no way to get proxy information other than through the console.vv file. If I am correct, then this means that both Opaque and remote-viewer cannot connect to VMs behind a proxy unless a console.vv file is used, which also means that since console.vv files are unobtainable through the User Portal on mobile devices, mobile devices effectively cannot at all connect to such VMs if the user is not an Administrator. Would it be possible to expose the proxy parameter through the API? I couldn't find a bug opened about this, but it doesn't mean it isn't there :). Thanks! iordan -- The conscious mind has only one thread of execution.

[Users] How to See Ovirt Console From a Remote Windows Host
by Jon Forrest 13 Oct '14

13 Oct '14

I know that this is simple for some of you, but I also know from Googling around that lots of people have had trouble seeing their ovirt console from a remote Windows host. Below I describe what finally worked for me. I hope this helps somebody avoid wasting as much time as I did today. I'm a fairly experienced VMWare user who's learning ovirt. I just installed an all-in-one ovirt server and copied a CentOS 6.5 iso into it. I then tried to boot a new VM but soon learned that console access is different in ovirt than on VMWare. I then spent over an hour trying the various documented ways to view a remote console using Spice on my Windows 7 desktop. I even tried using a Linux VM to see if the Firefox plugin for Spice would work. Nothing. What finally worked was installing the virt-viewer Windows client (http://virt-manager.org/download/) Then, I opened the ovirt Administration Portal in Firefox running on my Windows 7 desktop. I created a new VM and configured it the way I wanted. Then, from the "Virtual Machines" tab, I started the new VM. Pretty soon the little console icon turned green so I clicked on it. I got the prompt from Firefox asking me what app I wanted to associate with the ".vv" URL that opened when I clicked on the console icon. I browsed around and selected \Program Files\VirtViewer\bin\remote-viewer.exe which is from the virt-viewer client package I installed above. I told Firefox to always use this app for this kind of file. This works great! I was able to boot the CentOS system and install it with no problems. Good luck! Jon Forrest
