Re: [ovirt-users] Enabling GlusterFS in production

I think follow this steps: * Install manually vdsm-gluster * Restart supervdsm and vdsmd * Enable Gluster Service in my Cluster. Could it cause any problem or downtime? No, there should not be any issues due to this. When you manually install vdsm-gluster, the glusterfs packages will be installed. There's an additional step you will need to perform manually - peer probe the hosts to add these hosts to the gluster pool using gluster peer probe hostname To avoid the manual steps, is to re-install host after enabling gluster service - but this could cause a downtime.

[ovirt-users] ovirt network VLAN tagging
1. Create a new logical network from the networks main tab: define its data-center and set its vlan-id to 50 (the VM network checkbox should be checked) 2. Click on the created network in the networks main tab --- Select the 'Clusters' sub-tab and --- click on 'Assign/Unassign Network' and attach the network to the cluster (which contains the hosts that are expected to run the VMs). 3. Click on 'hosts' sub-tab of the network main tab for the same network. You should be able to see the cluster's hosts. Select a host and click on 'Setup Networks'. 4. In the 'setup networks' dialog you would see the host's interfaces on the left side and the logical networks definition on the right. Drag the network on top of an interface, or first drag a nic on top of another to create a bond and then drag the network to that bond. A command will be sent from the engine to the vdsm on the host to configure the desired network configuration. 5. In order to persist the network configuration on the host you can check the 'save network configuration' from 4. I followed the steps above to create two networks, vlan tagging nameed 50 and 60. My Engine has two hosts, that is, two nodes. And I created some vms. The vms which using different networks can not communicate with each other, this is right. But there is a question: the vms using the same network and in different hosts can not communicate with each other, but the vms using the same network and in the same host can communicate with each other. Could you please explain the reason for me and help me solve this problem?___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

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/ [1]). 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 FilesVirtViewerbinremote-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 Hi, I have one problem with that. I believe that the problem is rather in oVirt, not the viewer. I have oVirt installed at work and I also have connection to the work environment using IPv6 tunnelling (Windows WAN). In the oVirt all hosts are added using FQDN. The problem is that all hosts in the LAN (inside the company) are resolved via IPv4 and the same FQDN is resolved v ia IPv6 when I'm connected via WAN. In the console.vv file I can see the IPv4 address unfortunately and the connection to the console via WAN is not working. If I change the file putting FQDN to the host= line everything is working fine. How to change the oVirt? I'd prefer that the line host= contains the FQDN (or whatever is being put in the engine database) not the IP address? there's a Display address override per host where you can map each host's console address to something else; some other IP or FQDN you just need to set it for all hosts Thanks, michal Regards, Daniel ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users [2] Links: -- [1] http://virt-manager.org/download/ [2] http://lists.ovirt.org/mailman/listinfo/users ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Speaking of which, may I hijack this thread in order to ask why we don't have a slideshow template that looks like a slideshow template? With non-white background, colors in general, some graphics/patterns, thought-out bullet design, etc.? +1 here, you're more UI oriented person than I am , Lior , but now that you raised it, it suddenly popped into me as well - I would also like to see some improvement in that area. Thanks for the initiative! [cc'ing Brian and Eldan] Brian has been working on this kind of stuff lately. Brian, are you interested in working on making a prettier presentation template? Perhaps it could match our new PatternFly-based look -- just a thought. I'm sure we could find some design folks to help out (maybe Eldan? :)) Greg Yair This template just doesn't look like it means business. Not business as in the money-making way, business as in talking about a serious project with a serious brand. But maybe that's just me...
