[Users] xfs options for gluster storage
by Alexandr 17 Jan '14

17 Jan '14

Hi! I want to build small gluster storage with two nodes, 2x3Tb HDD in md-mirror on each. What parameters should I use in mkfs.xfs for optimal perfomance with ovirt? Should I use "-s size=4k" or something else?

[Users] Migration from NFS backed VM to iSCSI LUN without exporting them on the Ovirt Export Share
by squadra 17 Jan '14

17 Jan '14

Hello folks, since the nfs discussion remembered me that i got some vm left to migrate... here some kind of special question. i am open for non-bestpractice hacky solutions, too Situation is: - 2 Ovirt Cluster - Same DC - one NFS backed, one iSCSI backed - NFS Share and iSCSI Share are exported from the same phys. Machine - Bot DC use the same filer, just different Luns / Protocolls so, i thought about something simple like just move vm folder from a to b and do a little bit database voodoo? anyone did something like this yet? or is storage live migration already working for this? the docs didnt tell me very much about this.

[Users] New user to oVirt, and I haz a sad so far...
by Will Dennis (Live.com) 17 Jan '14

Hi all, ready for a story? (well, more of a rant, but hopefully it will be a good UX tale, and may even be entertaining.) Had one of the groups come to me at work this week and request a OpenStack setup. When I sat down and discussed their needs, it turns out that they really only need a multi-hypervisor setup where they can spin up VMs for their research projects. The VMs should be fairly long-lived, and will have persistent storage. Their other request is that the storage should be local on the hypervisor nodes (they plan to use Intel servers with 8-10 2TB drives for VM storage on each node.) They desire this in order to keep the VM I/O local - they do not have a SAN of any sort anyhow, and they do not care about live migration, etc. In any case, knowing that they did not want to afford a VMware setup (which is what I'm used to using), I proposed using oVirt to fill their needs, having heard and read up on it a bit (It's "open-source VMware", right?) even though I had not used it before (I have however made single-node KVM hypervisors for their group before, utilizing Open vSwitch, libvirt, virt-manager etc., so I'm not completely ignorant of KVM/libvirt etc.) In any case, I took one of their older servers which was already running CentOS 6.5, installed the requisite packages on it, and in short order had an engine server up and running (oVirt 3.3.2). That seems to have been the easy part :-/ Now came the installation of a hypervisor node. I downloaded and burned an ISO of the latest oVirt node installer (ovirt-node-iso-3.0.3-1.1.vdsm.fc19.iso) and tried to install it on one of their target Intel servers. On the 1st try I got to the end of the setup TUI, invoked the Install link, and was promptly thrown an error (sorry, but forgot what it was, something like "press X for a command prompt, or Reboot".) No problem, I rebooted, selected booting off the CD again, waited until the TUI came up, and when I tried to move past the first screen, it threw me out to a login prompt. OK, enough of that (the server takes a long time to reboot, and then boot off the CD) - I then thought I would try it on a VMware Workstation VM (yes, I get the irony, but VMware wkstn can handle nested virt, so it's a great testbed platform for OpenStack, etc.) because that would install a heck of a lot faster. That went a lot better - got the oVirt node 3.0.3 installed on the first try. More pain was soon to follow, however. I logged in and started configuring the node. The TUI was easy enough - much like an ESXi node ;) I set the NIC to IPv4 static, entered in the correct IP info, registered a DNS name for the IP I had assigned, and then tested pinging the engine, all was good. I then moved on to the section where you define the engine. I entered in the FQDN of the engine, verified the key fingerprint, and clicked the "Save and Register" link at the bottom. That seemed to work, so I completed the rest of the TUI, and then looked at the oVirt engine web UI. There was my new node, ready for authorization. I clicked the link to authorize it, and after a while, the UI came back with "Install Failed" status. Hmmm. So I went back to the node's TUI, and now some of the screens said that the IP addr was unconfigured? I went then to the Network screen, and sure enough, the NIC at the bottom showed "Unconfigured". WTF? So I went and entered in the correct info back in the IPv4 section, and then arrowed down to the Save link and clicked it - and the next screen said something like "No info needing changes, nothing to do." Whaaaa? Went back to the network setup screen, NIC still showing "Unconfigured" even though the IPv4 info still was there. I did a ping test at this point from the Ping link on the network setup page, and what do you know - I could still ping IP's (the engine, the default gw, etc.) But as I moved around the TUI, other screens still said that the network was unconfigured. Went back to the Web UI of the engine, put the host in Maint, then tried to Activate it, still no go - Install Failed. Even though I had configured the node to allow remote access and set a password, and also verified via nmap that TCP port 22 on the node was indeed listening, when I tried to SSH into the node as admin, I immediately got a "connection closed" message, so that failed as well. Went back to the node's network setup page, set the IPv4 to "Disabled", saved it, then went back and set it back to "Static" then re-entered the IPv4 info. Clicked the Save link, it went thru the setup again, came back with a success, verified with ping etc. that networking was working on the node. The engine web UI still said that it could not connect to the node however. So I put the node in Maint, and then removed it. I went back to the node, went to the Engine setup page, and re-did the screen to define the engine on the node. I notice that after I did this, however, that the node screens went back to saying that the network was unconfigured. Grrrrrr. But the node was back in the engine's Web UI, however no joy this time either - "Install failed" again. Well, the hell with this, said I - I removed the node again from the engine, and went and installed Fedora 19 minimal install on the VM, so I could use the directions found in http://www.ovirt.org/Quick_Start_Guide#Install_Fedora_Host and give that a try. (At least I can see what's going on with the node's OS using F19.) Installing F19 on the VM was a breeze, then logged in as root and did the "yum localinstall http://ovirt.org/releases/ovirt-release-fedora.noarch.rpm" which ran fine. I then stopped firewalld, and set it not to run at boot (which is what we typically do anyhow for internal research servers.) Then went over to the engine UI, and manually added the node. Oh happy day - the node seemed to install OK - it had the status of "Installing" for quite some time, and I looked at the processes on the F19 node, and could see python installer programs running via an SSH session from the engine. HOWEVER, at the end of the process, the Web UI reported a status of "Non Responsive", even though the F19 node looks OK (it had sanlock, supervdsmServer, vdsm processes running.) So thinking that it may take an after-install reboot, I did that, waited until the node came back up again, then clicked in the engine web UI and executed the "Confirm 'Host has been rebooted'" command, but still no good - the node remains in "Non Responsive" status. So I have no idea on how to proceed now, and what methods I can use to try and debug the connectivity problem between the engine and node. And there's many miles to go in setting up the whole environment. Maaaaaybe OpenStack would be easier ;-P No, I will press on and try to get this thing working... It seems it works for others, and looks like the right fit for the job. Just wish it was easier to get up and running. Oh yes, I tried reading the docs - go to http://www.ovirt.org/Quick_Start_Guide#Install_Hosts and click on the link for "see the oVirt Node deployment documentation." Not too helpful... (Bug report has been opened.) Thanks for reading, and any clues on getting a node up and running gratefully accepted... - Will

[Users] Create VLAN for WAN traffic
by Neil Schulz 17 Jan '14

17 Jan '14

I'm not very knowledgeable in VLANs. Sorry for the lack of knowledge in advance. Is it possible to create a VLAN for WAN traffic, to separate it from the internal network? I'd imagine so. It was a automated and simple process when use XenServer. I'm trying to switch from Xen to oVirt and when trying to recreate this, I'm unable to ping out from the VM. This leads me to believe the VLAN was created incorrectly. I created ifcfg-br1 on the host and through the engine, created the logical network with VLAN tagging 20. Does the interface, ifcfg-br1, require a public IP, any IP address, no ip address? (Sorry, never created a VLAN for WAN traffic as it was automated in XenServer) From there I have the VM installed and configured with a public IP address, however, only get Destination Host Unreachable, meaning it has no route out. I am banging my head on the desk trying to figure this out. Can anyone give me any assistance? Thank you, Neil

[Users] Ovirt DR setup
by Hans Emmanuel 17 Jan '14

17 Jan '14

Hi all , I would like to know about the possibility of setup Disaster Recovery Site (DR) for an Ovirt cluster . i.e if site 1 goes down I need to trigger the site 2 to come in to action with the minimal down time . I am open to use NFS shared storage or local storage for data storage domain . I know we need to replicate the storage domain and Ovirt confs and DB across the sites , but couldn't find any doc for the same , isn't that possible with Ovirt ? *Hans Emmanuel* *NOthing to FEAR but something to FEEL......*

[Users] Ovirt in the cloud
by Rob Abshear 17 Jan '14

Is it possible to use leased dedicated servers as ovirt nodes? In my mind it seems likely, but input from the community would be appreciated. I'm envisioning a controller node running on a dedicated server leased from a provider and multiple compute nodes running on several different providers spread out over the net. I don't require any migration capability for the purposes of this. I manage a large farm of servers, and if this works like I think it would, I believe it would speed up deployment of new servers and also provide a better central management platform. If this is possible, what would be the requirements, pitfalls, etc.? Thanks in advance. -- *NADA Convention & Expo*: January 24-27, 2014 - New Orleans, LA - Booth 5001 <http://www.bbb.org/south-east-florida/business-reviews/advertising-agencies…><http://www.bbb.org/south-east-florida/business-reviews/advertising-agencies…>

[Users] Attach NFS storage to multiple datacenter
by Tobias Fiebig 17 Jan '14

17 Jan '14

Heho, for some reason i currently have two active datacenters in ovirt 3.3 which should be cold migrated to one new datacenter. Is there a simple way to attach an nfs-storage to all datacenters, so it can be used to migrate the virtual machines? I was sadly unable to find documentation on this issue online... With best Regards, Tobias
