[Users] Logical networks in 3.1 on CentOS 6.3
by Frank Soyer 04 Oct '12

04 Oct '12

Hi list, I'm testing oVirt on 3 hosts as a possible replacement for Proxmox. I've some trouble to understand the network part of the config (for beginning, I'll have some other questions about glusterfs later :)) and need some lights. The environment : - Engine host, no-virtualisation capability, one NIC eth0 - 2 nodes, virtualisation OK, 2 NICs eth0,eth1 - oVirt 3.1 on CentOS 6.3. The installation of engine/nodes was OK, no problem at all on the 3 nodes. The NIC eth0 on all hosts was manually bound on a bridge "ovirtmgmt", respectively on 10.0.0.1, .2, .3 ovirmgmt appears on the console as the management network, no problem, just a first question : it is marked as "VM network", and no way to change that. What if I want that this network to be dedicated on physical hosts only ? Second, I tried to create a logical network, call it "vmnetwork", linked it to datacenter and cluster. In the network interface configuration window on the hosts, I can link vmnetwork on eth0, but when validating an error occurs saying that eth0 is already linked to ovirmgmt. So I can't have management network and vm network on the same NIC , even on a virtual nic (tried with vlan=0 and vlan=10 on vmnetwork, same thing) ? Third, is this a bug when I come back to the configuration window, that the networks (for ovirmgmt and vmnetwork) return to "DHCP" ? If I forgot to re-check the static network, the host lose all it's network config and is declared non-responsive then rebooted..... Bad ! Thank you for helping me to understand. Frank

[Users] Question about network card order
by Kevin Maziere Aubry 03 Oct '12

03 Oct '12

Hello My first email on the mailing, I hope the first one of a longue serie. The email concerns a Network Card order issue for which I like to report a have your advises. I've made a template which contains 2 network cards, Each one bridge on different vlan network. When I create a VM from this template, the network card mac address assignation is random... so that by default my fedora assign eth0 to the smallest mac address, and so on for eth1/eth2 ... But no way to define network card order in template, so that sometime the smallest mac address is on eth0, sometime on eth1 (and in fact more often on eth1), sometime my VM works, sometime I have to destroy and recreate network interfaces. Is there a workaround or anything else ?

[Users] fw: Migrating ovirt-engine to new server
by Neil 03 Oct '12

03 Oct '12

Sorry to repost(kind of) but I'm really battling here and I need to get the VM's up and running again. I've given up on the idea of migrating the database across due to all sorts of problems encountered and I've instead done a completely NEW fresh ovirt-engine install and I've got one host added and running. How do I go about detaching my storage datacentre from my old ovirt-engine, and re-attaching it to my new ovirt-engine running on my new server? I'm running FC with multiple LUNS all assigned in one datacentre called "linux" and I can't detach it because it says "Cannot detach Storage Domain while VMs/Templates reside on it." My entire datacentre is in maintenance at the moment which consists of only 3 VM's(4TB's in total), my host only has a 16GB SDD in it, so exporting to a local NFS mount is not an option. Can I safely remove the VM's(as instructed above) by going to "VM's" and clicking remove and then will I be able to detach the datacentre and then re-attach it to the new ovirt-engine? Bearing in mind that I'm running a fresh install of ovirt-engine and I haven't copied the database across? Is it a matter of re-attaching the LUNS that are currently assigned because I can see the LUNS when I try and add a new FC storage domain, however the LUNS currently attached to the old ovirt-engine are greyed out and can't be selected. Any assistance is greatly appreciated. Thank you. Regards. Neil Wilson.

[Users] nested KVM
by Nathanaël Blanchet 03 Oct '12

Hello, I've tried many times to run a node as a guest in ovirt following http://wiki.ovirt.org/wiki/Vdsm_Developers#Running_Node_as_guest_-_Nested_K… . The result is that I'm able to register such a host in engine, but it is impossible to start any vm on it. If I boot on an ISO, I can see the first prompt and move between the items. But since I begin the installation I have a blank screen and the vm goes into pause mode in vit-manager. Then I have no way else than rebooting the hypervisor guest because it is impossible to resume. When I get logs on the real host, I can find this : arning : x86Decode:1306 : Preferred CPU model Westmere not allowed by hypervisor; closest supported model will be used Sep 25 17:11:59 khamsin libvirtd[23053]: 2012-09-25 15:11:59.384+0000: 23054: warning : x86Decode:1306 : Preferred CPU model Westmere not allowed by hypervisor; closest supported model will be used Sep 25 17:12:19 khamsin libvirtd[23053]: 2012-09-25 15:12:19.150+0000: 23055: warning : x86Decode:1306 : Preferred CPU model Westmere not allowed by hypervisor; closest supported model will be used Sep 25 17:45:48 khamsin libvirtd[23053]: 2012-09-25 15:45:48.342+0000: 23058: warning : x86Decode:1306 : Preferred CPU model Westmere not allowed by hypervisor; closest supported model will be used Sep 25 18:07:05 khamsin libvirtd[23053]: 2012-09-25 16:07:05.834+0000: 23058: warning : x86Decode:1306 : Preferred CPU model Nehalem not allowed by hypervisor; closest supported model will be used Sep 25 18:44:47 khamsin libvirtd[23053]: 2012-09-25 16:44:47.340+0000: 23057: warning : x86Decode:1306 : Preferred CPU model Penryn not allowed by hypervisor; closest supported model will be used As you can see, I have tried many cpu type for launching this guest hypervisor, but none of them is accepted by the hypervisor.

[Users] Migrating ovirt-engine to new server
by Neil 03 Oct '12

03 Oct '12

Hi guys, Please could someone assist me. I'm trying to migrate my ovirt-engine(3.1 but very early release) to latest 3.1 on new machine(both Centos 6.3 dreyou repo). After the intial engine-setup I can log into webadmin without a problem. I then imported my DB from the old server (psql -U postgres -d engine -w < /root/dump.sql) and start the ovirt-engine again, but now when try and browse to the webadmin I don't get anything at all, no web page displays at all, I'm guessing that there are lots of additional steps that I'm missing, so perhaps this is normal. I haven't attached any logs etc because I'm fairly certain that I'm missing some vital steps before I can actually log into my system using the new DB. I've changed the hostname of the machine -- previous name was node02.blabla.com and now it's backup.blabla.com does this matter? My guess is the certificates won't work with the DB now, is there any way to get around this, or should I rather just use the same hostname on the new server? I also haven't copied any physical files or configs across yet, which files/folders do I need? I'm using a FC SAN so I'm assuming I won't need to export my VM's, it should just be a matter of detaching my main storage domain and then re-attaching it on the new server? I see when I try and detach from the old server it says "can't export while there are Templates/VM's on the system" must I hit the remove button on each VM on the old system in order to detach and then attach to on the new system? (presume it will only remove the VM's from the old system and not actually delete the VM image?) I'm using no templates, so I'm assuming these don't need to be exported/imported? Sorry for all the questions, any help is greatly appreciated! Regards. Neil Wilson.

[Users] General challenges w/ Ovirt 3.1
by Hans Lellelid 02 Oct '12

02 Oct '12

Hi - I apologize in advance that this email is less about a specific problem and more a general inquiry as to the most recommended / likely-to-be-successful way path. I am on my third attempt to get an ovirt system up and running (using a collection of spare servers, that meet the requirements set out in the user guide). I'm looking to implement a viable evolution to the unscalable stove-piped ESXi servers (i.e. which are free). And while I'm happy to learn more about the underpinnings, I recognize that to really be a replacement for these VMWare solutions, this has to mostly "Just Work" -- and that's eventually why I've given up on previous occasions (after a couple days of work) and decided to revisit in 6 months. My basic server setup is: - oVirt Mgmt (engine) - oVirt HV1 (hypervisor node) - oVirt HV2 (hypervisor node) - oVirt Disk (NFS share) 1st attempt: I installed the latest stable Node image (2.5.1) on the HV1 and HV2 machines and re-installed the Mgmt server w/ Fedora 17 (64-bit) and all the latest stable engine packages. For the first time, Node installation and Engine setup all went flawlessly. But I could not mount the NFS shares. Upon deeper research, this appeared to be the bug mentioned about NFS; I was *sure* that the official stable Node image would have had a downgraded kernel, but apparently not :) I have no idea if there is an officially supported way to downgrade the kernel on the Node images; the warnings say that any changes will not persist, so I assume there is not. (I am frankly a little surprised that the official stable packages & ISO won't actually work to mount NFS shares, which is the recommended storage strategy and kinda critical to this thing!?) . FWIW, the oVirt Disk system is a CentOS 6.2 system. 2nd attempt: I re-installed the nodes as Fedora 17 boxes and downgraded the kernels to 3.4.6-2. Then I connected these from the Engine (specifying the root pw) and watched the logs while things installed. After reboot neither of the servers were reachable. Sitting in front of the console, I realized that networking was refusing to start; several errors printed to the console looked like: device-mapper: table: 253:??: multipath: error getting device (I don't remember exactly what was after the "253:") calling "multipath -ll" yielded no output, calling "multipath -r" re-issued the above errors Obviously the Engine did a lot of work there, setting up the bridge, etc. I did not spend a long time trying to untangle this. (In retrospect, I will go back and probably spend more time trying to track this down, but it's difficult since I lose network & have to stand at the console in the server room :)) 3rd attempt: I re-installed the nodes with Fedora 17 and attempted to install VDSM manually by RPM. Despite following the instructions to turn off ssl (ssl=false in /etc/vdsm/vdsm.conf), I am seeing SSL "unknown cert" errors from the python socket server with every attempt of the engine to talk to the node. I added the CA from the master into the /etc/pki/vdsm (since that was the commented-out path in the config file as the trust store) and added the server's cert here too, but have no idea what form these files should take to be respected by the python server -- or if they are respected at all. I couldn't find this documented anywhere, so I left the servers spewing logs for the weekend figuring that I'll either give up or try another strategy on Monday. So is there a general strategy that should get me to a working system here? I suspect that the Node image is not a good path, since it appears to be incompatible with NFS mounting. The Fedora-17-installed-by-engine sounds good, but there's a lot of magic there & it obviously completely broke my systems. Is that where I should focus my efforts? Should I ditch NFS storage and just try to get something working with local-only storage on the nodes? (Shared storage would be a primary motivation for moving to ovirt, though.) I am very excited for this to work for me someday. I think it has been frustrating to have such sparse (or outdated?) documentation and such fundamental problems/bugs/configuration challenges. I'm using pretty standard (Dell) commodity servers (SATA drives, simple RAID setups, etc.). Sorry for no log output, I can provide more of that when back at work on Monday, but this was more of a general inquiry on where I should plan to take this. Thanks in advance! Hans

[Users] VM stuck in state Not Responding
by Patrick Hurrelmann 30 Sep '12

30 Sep '12

Hi List, in my test lab the iSCSI SAN crashed and caused some mess. My cluster has 3 hosts running VMs. The SPM node was fenced and automatically shutdown due to the storage crash. All VMs running on the other 2 hosts were put to pause. I recovered the storage and powered on the fenced node. All VMs were restarted or coming back to live except one. Since this incident I am no longer able to start oder stop it. It is stuck in state "Not Responding" and it seems I cannot revive it anymore. The engine only provides the stop or shutdown operations, but none works. The following is logged when trying to stop it: 2012-09-28 12:29:08,415 INFO [org.ovirt.engine.core.bll.StopVmCommand] (pool-3-thread-50) [49165a9b] Running command: StopVmCommand internal: false.

[Users] general (totally noob) questions...
by Michael Hauber 26 Sep '12

26 Sep '12

While I am not completely new to running instances in KVM/Qemu, I am a total noob when it comes to clustering. While I realize that not all of these questions pertain specifically to the oVirt project, I would much rather get input from people that have experience in this environment. I am in the process of designing my next server farm and would like to know some basics that I can't seem to find the answers to via google search. Background: I have a server farm setup for a large family. It consists of 9 servers (minimal-to-medium loads for the most part, but they are in poor condition physically). My hopes are to run this same setup virtually in a 3-node cluster. I can run the entire farm in a virtual environment on a host with a dual, quad-core box with 64gig RAM. That said, I know that each of these nodes will be capable of handling the entire load by itself if absolutely necessary. For disk space, my hopes are to use two drive arrays (10 configuration?) which I can build (up and out) from without having too much trouble. Everything will be fiber, including drops to the computers and televisions. Copper will exist as well for things like POE, printers, etc. (but not in scope) Questions: 1. As I understand it, a N-to-N configuration means that there will be load balancing between the nodes as well as failover. Is the load balancing something that is manual (I have to monitor/balance the load manually, or is it done automatically?) 2. If it is done automatically, how do the loads get split up? Is the virtual machine itself the unit of load that transfers from one node to another or does it go so far as balancing services running inside those virtual machines? 3. For the fail-over, is it seemless in the sense that the user's connections don't get reset or is there a short period of down-time before the service is available again? While this isn't a big issue for me, it is something that I've been wondering about. 4. Fibre channel or FCOE? (I've spent entire evenings trying to get a straight answer through google searches, but there seem to be way too many agendas). Being that one of the virtual servers will be a media server for the televisions (new addition), my worry is lag-time (I would like to serve at least 5 televisions without lag-time). The array will also support things like file server, space for about 2-dozen www (family pages (lots of pictures)), space for mail, space for backups (rSync,Amanda), ISO boots, etc. I have the logical and physical topology drawn up for the most part, but until I understand a bit more, I'm scared _less about dropping any money into the project because I've neither seen a setup like this in action, and what I find online seems a bit vague in the way of details (dumbed-down enough for the likes of me to know if the hardware I'm buying is necessary and/or sufficient to achieve my goals). Any and all pointers, suggestions, patience, etc. would be greatly appreciated. mchauber

[Users] I can't figure out how to add a user?
by Alan Johnson 26 Sep '12

26 Sep '12

First off, oVirt noob alert. That said, I have been able to figure out and over come most of my issues getting oVirt running on CentOS 6.3 the various documentation that is available, including this list's archives for the last few months. (Side question: I haven't found a good way to search the archives short of using site: within google search, but that does not seem to work so well, so I have been relying on gmail's collection of the messages since I subscribed a few months ago. Is there a better way?) Anyway, this one seems like it should be so simple that I feel like I must be missing some thing painfully obvious. That is, I don't seem to be able to create a user. The GUI's add button on the user tab just lets me search existing users, but does not provide anywhere to enter new user info. I have successfully "added" the admin@internal user several times while bumbling around with that interface, but this is not terribly helpful since it has always been there. To what I have added it, I am am not entirely clear. I don't see anything in the getting started guide, and the administrator guide just walks me through the same useless steps I mentioned above in the user tab. Any nudge in the right direction would be greatly appreciated. I'll even accept dope slaps at this point if warranted. =) Thanks in advance for your time and consideration. _______________ Alan Johnson alan(a)datdec.com

[Users] Installation problem
by Dave Neary 24 Sep '12

24 Sep '12

Hi all, I was working through the installation of ovirt-engine today (after spending more time than I care to admit struggling with networking & DNS issues - VPNs, dnsmasq, "classic" network start-up and iptables/firewall rules can interract with each other in strange and surprising ways). Anyway - I went through the engine set-up successfully, and got the expected message at the end: "**** Installation completed successfully ******" with a message to visit the engine web application to finish set-up. Unfortunately, when I connected (after resolving networking issues) to the server in question, I got a "Service temporarily unavailable" error (503) from Apache. in httpd's error.log, I have: > [Fri Sep 21 13:37:03 2012] [error] (111)Connection refused: proxy: AJP: attempt to connect to 127.0.0.1:8009 (localhost) failed > [Fri Sep 21 13:37:03 2012] [error] ap_proxy_connect_backend disabling worker for (localhost) > [Fri Sep 21 13:37:03 2012] [error] proxy: AJP: failed to make connection to backend: localhost When I try to restart the ovirt-engine service, I get the following in journalctl: > Sep 21 13:34:44 clare.neary.home engine-service.py[5172]: The engine PID file "/var/run/ovirt-engine.pid" already exists. > Sep 21 13:34:44 clare.neary.home systemd[1]: PID 1264 read from file /var/run/ovirt-engine.pid does not exist. > Sep 21 13:34:44 clare.neary.home systemd[1]: Unit ovirt-engine.service entered failed state.

You can either reduce the request size or reconfigure the kernel with larger SHMMAX.

I increased the kernel's SHMMAX, and engine-cleanup worked correctly. Has anyone else experienced this issue? When I re-run engine-setup, I also got stuck when reconfiguring NFS - when engine-setup asked me if I wanted to configure the NFS domain, I said "yes", but then it refused to accept my input of "/mnt/iso" since it was already in /etc/exports - perhaps engine-cleanup should also remove ISO shares managed by ovirt-engine, or else handle more gracefully when someone enters an existing export? The only fix I found was to interrupt and restart the engine set-up. Also, I have no idea whether allowing oVirt to manage iptables will keep any extra rules I have added (specifically for DNS services on port 53 UDP) which I added to the iptables config. I didn't take the risk of allowing it to reconfigure iptables the second time. After all that, I got an error when starting the JBoss service: > Starting JBoss Service... [ ERROR ] > Error: Can't start the ovirt-engine service > Please check log file /var/log/ovirt-engine/engine-setup_2012_09_21_14_28_11.log for more information And when I checked that log file: > 2012-09-21 14:30:02::DEBUG::common_utils::790::root:: starting ovirt-engine > 2012-09-21 14:30:02::DEBUG::common_utils::835::root:: executing action ovirt-engine on service start > 2012-09-21 14:30:02::DEBUG::common_utils::309::root:: Executing command --> '/sbin/service ovirt-engine start' > 2012-09-21 14:30:02::DEBUG::common_utils::335::root:: output = > 2012-09-21 14:30:02::DEBUG::common_utils::336::root:: stderr = Redirecting to /bin/systemctl start ovirt-engine.service > Job failed.

[Users] SPM not selected after host failed
by "Marc-Christian Schröer | ingenit GmbH & Co. KG" 24 Sep '12

24 Sep '12

Hello all, we are currently in the process of evaluating oVirt as a basis for our new virutalization environment. As far as our evaluation has processed it seems to be the way to go, but when testing the high availability features I ran into a serious problem: Our testing setup looks like this: 2 hosts on Dell R210 and R210II machines, a seperate machine running the managing application in JBoss and providing storage space through NFS. Under normal conditions everything works fine: I can migrate machines between the two nodes, I can add a third node, access everything by VNC, monitor the VMs really nicely, the power management feature of the R210s work just fine. Then, when simulating the loss of a host by pulling the plug on the machine, (yes, that is kind of a crude check) some things seem to go terribly wrong: the system detects the host being unresponsive and assumes it is down. But the host happens to be the SPM and the other does not take over this function. This leaves the hole cluster in an unresponseive state and my datacenter is gone. I tracked down the problem in the log files to the point where the engine tries to migrate the SPM to another node: 2012-09-20 07:54:40,836 INFO [org.ovirt.engine.core.vdsbroker.irsbroker.IrsBrokerCommand] (QuartzScheduler_Worker-60) SPM selection - vds seems as spm node03 2012-09-20 07:54:40,837 WARN [org.ovirt.engine.core.vdsbroker.irsbroker.IrsBrokerCommand] (QuartzScheduler_Worker-60) spm vds is non responsive, stopping spm selection. 2012-09-20 07:54:44,344 ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.VdsBrokerCommand] (QuartzScheduler_Worker-51) XML RPC error in command GetCapabilitiesVDS ( Vds: node03 ), the error was: java.util.concurrent.ExecutionException: java.lang.reflect.InvocationTargetException, NoRouteToHostException: Keine Route zum Zielrechner 2012-09-20 07:54:47,345 ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.VdsBrokerCommand] (QuartzScheduler_Worker-47) XML RPC error in command GetCapabilitiesVDS ( Vds: node03 ), the error was: java.util.concurrent.ExecutionException: java.lang.reflect.InvocationTargetException, NoRouteToHostException: Keine Route zum Zielrechner 2012-09-20 07:54:50,869 INFO [org.ovirt.engine.core.vdsbroker.irsbroker.IrsBrokerCommand] (QuartzScheduler_Worker-69) hostFromVds::selectedVds - node04, spmStatus Free, storage pool ingenit 2012-09-20 07:54:50,892 ERROR [org.ovirt.engine.core.vdsbroker.irsbroker.IrsBrokerCommand] (QuartzScheduler_Worker-69) SPM Init: could not find reported vds or not up - pool:ingenit vds_spm_id: 2 2012-09-20 07:54:50,905 INFO [org.ovirt.engine.core.vdsbroker.irsbroker.IrsBrokerCommand] (QuartzScheduler_Worker-69) SPM selection - vds seems as spm node03 As far as I understand these logs, the engine detects node03 not being responsive, starts electing a new SPM but does not find node04. That is strange as the host is online, pingable and worked just fine as part of the cluster. What I can do to remedy the situation using the management interface to set "Confirm Host has been rebooted" and switch the host into maintenance mode after that. Than the responsive node takes over and the VMs are being migrated, too. Has anyone experienced a similar problem? Is this by design and killing off the SPM is a bad coincident and always requires manual intervention? I would hope not :-) I tried to google some answers, but aside from a thread in May that did not help I came up empty. Thanks in advance for all the help...

If yes, do I need to open a BZ?
