[ANN] oVirt 4.1.7 Third Release Candidate is now available
by Sandro Bonazzola 11 Oct '17

11 Oct '17

The oVirt Project is pleased to announce the availability of the Third Release Candidate of oVirt 4.1.7, as of October 11th, 2017 This update is the seventh in a series of stabilization updates to the 4.1 series. Starting from 4.1.5 oVirt supports libgfapi [5]. Using libgfapi provides a real performance boost for ovirt when using GlusterFS . Due to a known issue [6], using this will break live storage migration. This is expected to be fixed soon. If you do not use live storage migration you can give it a try. Use [7] for more details on how to enable it. This release is available now for: * Red Hat Enterprise Linux 7.4 or later * CentOS Linux (or similar) 7.4 or later This release supports Hypervisor Hosts running: * Red Hat Enterprise Linux 7.4 or later * CentOS Linux (or similar) 7.4 or later * oVirt Node 4.1 See the release notes draft [3] for installation / upgrade instructions and a list of new features and bugs fixed. Notes: - oVirt Appliance is already available - oVirt Live is already available[4] - oVirt Node is already available[4] Additional Resources: * Read more about the oVirt 4.1.7 release highlights: http://www.ovirt.org/release/4.1.7/ * Get more oVirt Project updates on Twitter: https://twitter.com/ovirt * Check out the latest project news on the oVirt blog: http://www.ovirt.org/blog/ [1] https://www.ovirt.org/community/ [2] https://bugzilla.redhat.com/enter_bug.cgi?classification=oVirt [3] http://www.ovirt.org/release/4.1.7/ [4] http://resources.ovirt.org/pub/ovirt-4.1-pre/iso/ [5] http://staged-gluster-docs.readthedocs.io/en/release3.7.0beta1/Features/lib… [6] https://bugzilla.redhat.com/show_bug.cgi?id=1306562 [7] http://www.ovirt.org/develop/release-management/features/storage/glusterfs-… -- SANDRO BONAZZOLA ASSOCIATE MANAGER, SOFTWARE ENGINEERING, EMEA ENG VIRTUALIZATION R&D Red Hat EMEA <https://www.redhat.com/> <https://red.ht/sig> TRIED.

Info on manual operations after removing FC storage domain
by Gianluca Cecchi 11 Oct '17

11 Oct '17

Hello, I'm relocating some disks from some storage domains to other ones. At the end I'm going to remove source storage domains. All the SD involved are FC and the hosts are CentOS 7.4 I see that after removing an SD from oVirt, the multipath part on host remains. What is the correct sequence of operations to do at hosts' side after completing the Webadmin Gui part? Some questions: - do the remove SD from gui imply vgchange -an of the VG and vgremove of the vg? Or are they delegated to post actions? - do it imply the pvremove on the LUN? After clearing what above I would imagine remaining steps would be, based on my previous similar experience with iSCSI removal on physical servers: - take note of the paths sdY, ... of mpathX - remove the multipath device with multipath -f mpathX - flush the single paths devices blockdev --flushbufs sdY for every path of the previous taken note ones - remove single path devices echo 1 > /sys/block/sdY/device/delete - remove LUN from storage array when previous steps done on all the hypervisors Any comment? Any further step at vdsm level files..? Thanks in advance, Gianluca

Maximum storage per VM?
by Dmitri Chebotarov 11 Oct '17

11 Oct '17

Hello I'm trying to find any info on how much storage I can attach to a VM. Is there a recommended/maximum for number of disks and maximum disk size? I'm using GlusterFS as backend storage for the cluster. The VM uses LVM (/w striped volumes) to manage attached disks. Thank you, -- Dmitri Chebotarov.

multipath configuration for local disks?
by Matthias Leopold 10 Oct '17

10 Oct '17

hi, i'm using three different generations of hardware for my oVirt hypervisor hosts. they are not exactly the "same", but very "similar". - all were installed with oVirt Node 4.1.x installers - all have (2-4) local SSD disks for oVirt Node OS - all were configured with manual partitioning and SW RAID 1 with two SSD disks for oVirt Node OS after initializing the third generation of hosts (with 4 SSD disks) i noticed the difference in multipath configuration for the local disks. suddenly the two OS disks (for RAID 1) are not configured as multipath disks anymore, the unused other two are multipath disks. in the first two host generations the (only) two OS disks (for RAID 1) are configured as multipath disks. after looking at this for the first time and briefly looking into multipath documentation i think that local disks shouldn't be included in multipath configuration at all. i tried to remove the local disks from multipathing (delete from wwids file, explicit blacklisting), to no avail. i'm pasting two listings from the 4 SSD disk situation: # lsscsi --scsi_id -g [0:0:0:0] disk ATA SAMSUNG MZ7LM480 204Q /dev/sda - /dev/sg0 [0:0:1:0] disk ATA SAMSUNG MZ7LM480 204Q /dev/sdb - /dev/sg1 [0:0:2:0] disk ATA SAMSUNG MZ7LM480 204Q /dev/sdc SAMSUNG_MZ7LM480HMHQ-00005_S2UJNX0J102216 /dev/sg2 [0:0:3:0] disk ATA SAMSUNG MZ7LM480 204Q /dev/sdd SAMSUNG_MZ7LM480HMHQ-00005_S2UJNX0J102214 /dev/sg3 # ls -l /dev/disk/by-id/*SAMSUNG* lrwxrwxrwx. 1 root root 9 9.

Ovirt 4.2 Fencing problems
by Maton, Brett 10 Oct '17

10 Oct '17

Hi, I recently upgraded my testlab to oVirt 4.2-pre and have been having some issues. One of which is fencing with Dell Drac 8 remote access cards. The configuration I'm using works fine on my other (4.1.6) cluster... Error: Health check on Host host.example.com indicates that future attempts to Start this host using Power-Management are expected to fail. Fence agent setup for the host appears to be working though: Which logs would be helpful in debugging this issue ? Regards, Brett

VM-Clone issue
by Shamam Amir 09 Oct '17

09 Oct '17

Dear All, We are using oVirt release *Version 4.1.5.2. *I was trying to make a clone of a VM but I got the following message* "*Error while executing action CloneVm: Internal Engine Error", I found that when cloud-init is used in the vm's edit section, this error occurs, but when the vm is configured without cloud init, the clone was completed successfully. I wondered if this is a bug or something else? The log file is in this link https://paste.fedoraproject.org/paste/f~sHprL93BNZ-iJzoFDyww Best Regards

Engine crash, storage won't activate, hosts won't shutdown, template locked, gpu passthrough failed
by M R 09 Oct '17

09 Oct '17

Hello! I have been using Ovirt for last four weeks, testing and trying to get things working. I have collected here the problems I have found and this might be a bit long but help to any of these or maybe to all of them from several people would be wonderful. My version is ovirt node 4.1.5 and 4.1.6 downloaded from website latest stable release at the time. Also tested with CentOS minimal +ovirt repo. In this case, 3. is solved, but other problems persist. 1. Power off host First day after installing ovirt node, it was able to reboot and shutdown clean. No problems at all. After few days of using ovir, I have noticed that hosts are unable to shutdown. I have tested this in several different ways and come to the following conclusion. IF engine has not been started after boot, all hosts are able to shutdown clean. But if engine is started even once, none of the hosts are able to shutdown anymore. The only way to get power off is to unplug or press power button for a longer time as hard reset. I have failed to find a way to have the engine running and then shutdown host. This effects to all hosts in the cluster. 2. Glusterfs failed Every time I have booted hosts, glusterfs has failed. For some reason, it turns inactive state even if I have setup systemctl enable glusterd. Before this command it was just inactive. After this command, it will say "failed (inactive). There is still a way to get glusterfs working. I have to give command systemctl start glusterd manually and everything starts working. Why do I have to give manual commands to start glusterfs? I have used this for CentOS before and never had this problem before. Node installer is that much different from the CentOS core? 3. Epel As I said that I have used CentOS before, I would like to able to install some packets from repo. But even if I install epel-release, it won't find packets such as nano or htop. I have read about how to add epel-release to ovirt node from here: https://www.ovirt.org/release/4.1.1/#epel I have tested even manually edit repolist, but it will fail to find normal epel packets. I have setup additional exclude=collectd* as guided in the link above. This doesn't make any difference. All being said I am able to install manually packets which are downloaded with other CentOS machine and transferred with scp to ovirt node. Still, this once again needs a lot of manual input and is just a workaround for the bug. 4. Engine startup When I try to start the engine when glusterfs is up, it will say vm doesn't exist, starting up. Still, it won't startup automatically. I have to give several times command hosted-engine --vm-start. I wait for about 5minutes until I give it next time. This will take usually about 30minutes and then randomly. Completely randomly after one of the times, I give this command engine shoots up and is up in 1minute. This has happened every time I boot up. And the times that I have to give a command to start the engine, has been changing. At best it's been 3rd time at worst it has been 7th time. Calculating from there it might take from 15minutes to 35minutes to get the engine up.Nevertheless, it will eventually come up every time. If there is a way to get it up on the first try or even better, automatically up, it would be great. 5. Activate storage Once the engine is up, there has been a problem with storage. When I go to storage tab, it will show all sources red. Even if I wait for 15~20minutes, it won't get storage green itself. I have to go and press active button from main data storage. Then it will get main storage up in 2~3munutes.Sometimes it fails it once, but will definitely get main data storage up on the seconds try. And then magically at the same time all other storages instantly go green. Main storage is glusterfs and I have 3 NFS storages as well. This is only a problem when starting up and once storages are on green they stay green. Still annoying that it cannot get it done by itself. 6.Template locked I try to create a template from existing VM and it resulted in original VM going into locked state and template being locked. I have read that some other people had a similar problem and they were suggested to restart engine to see if it solves it. For me it has been now a week and several restarts of engine and hosts, but there is still one VM locked and template locked as well. This is not a big problem, but still a problem. Everything is grey and cannot delete this bugged VM or template. 7. unable to use GPU I have been trying to do GPU passthrough with my VM. First, there was a problem with qemu cmd line, but once I figure out a way to get commands, it maybe is working(?). Log shows up fine, but it still doesn't give functionality I¨m looking for. As I mentioned in the other email that I have found this: https://www.mail-archive.com/users@ovirt.org/msg40422.html . It will give right syntax in log, but still, won't fix error 43 with nvidia drivers. If anybody got this working or has ideas how to do it, would really like to know how it's done properly. I have also tested with AMD graphics cards such as vega, but as soon as drivers have installed, I will get a black screen. Even if I restart VM or hosts or both. I will only see black screen and unable to use VM at all. I might be able to live with the other six things listed above, but this one is a bit of a problem for me. My use of VMs will eventually need graphical performance and therefore I will have to get this working or find an alternative to ovirt..I have found several things that I really like in ovirt and would prefer to use it.

Help - Host unresponsive!
by Wesley Stewart 09 Oct '17

09 Oct '17

I have a single server that is running ovirt as a host and a storage domain. I ran an update when the GUI told me that there was one. I shutdown all of the VM's, placed the host in maintenance mode and did the update. Upon rebooting the server, I was able to pull my VM's online without any issue, but then, all of a sudden, vm's stopped responding as well as the host. The host is showing as "Down" and I cannot "Activate" it. Also "Maintenance Mode" is greyed out. Storage pools are "down" but eventually come back online, but the host still will not come online. Every few minutes, the host goes to "UP" right before failing and going back "Down". To make it more confusing, like I mentioned before, this is all in one box, so it isn't like their is a network issue between the storage and the host boxes or anything. Currently trying to reinstall the host and see if that helps, but I would very much appreciate any sort of guidance, support or ideas! Fencing failed on Storage Pool Manager OVIRT-Host for Data Center OVIRT-Datacenter. Setting status to Non-Operational. Host OVIRT-Host failed to recover.

VM remote noVNC console
by Alex K 06 Oct '17

06 Oct '17

Hi all, I am trying to get the VM console of a VM through SSH socks proxy. This is a scenario I will frequently face, as the ovirt cluster will be available only though a remote SSH tunnel. I am trying several console options without success. With SPICE or VNC I get issue with virt-viewer saying "Unable to connect to libvirt with URI [none]' With noVNC I get a separate tab on browser where it is stuck showing "loading". Has anyone success with this kind of remote console access? Thanx, Alex

Debugging warning messages about bonding mode 4
by Gianluca Cecchi 06 Oct '17

06 Oct '17

Hello, on a 2 nodes cluster in 4.1.6 I have this situation. Every node has 3 bonds, each one composed by 2 network adapters and each one of type mode=4 (actually in setup networks I have configured custom and then the value: "mode=4 miimon=100" ) At this moment only one of the servers has access to FC storage, while the other is currently on maintenance. On 2 of the 3 bonds of the active server I get an exclamation point in "Network Interfaces" subtab with this mouseover popup Bond is in link aggregation mode (mode 4), but no partner mac has been reported for it What is the exact meaning of this message? Do I have to care about (I think so..)? What should I report to network guys? Eg, one of these two warning bonds status is: # cat /proc/net/bonding/bond2 Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011) Bonding Mode: IEEE 802.3ad Dynamic link aggregation Transmit Hash Policy: layer2 (0) MII Status: up MII Polling Interval (ms): 100 Up Delay (ms): 0 Down Delay (ms): 0 802.3ad info LACP rate: slow Min links: 0 Aggregator selection policy (ad_select): stable System priority: 65535 System MAC address: 48:df:37:0c:7f:5a Active Aggregator Info: Aggregator ID: 5 Number of ports: 2 Actor Key: 9 Partner Key: 6 Partner Mac Address: b8:38:61:9c:75:80 Slave Interface: ens2f2 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 2 Permanent HW addr: 48:df:37:0c:7f:5a Slave queue ID: 0 Aggregator ID: 5 Actor Churn State: none Partner Churn State: none Actor Churned Count: 2 Partner Churned Count: 3 details actor lacp pdu: system priority: 65535 system mac address: 48:df:37:0c:7f:5a port key: 9 port priority: 255 port number: 1 port state: 61 details partner lacp pdu: system priority: 32768 system mac address: b8:38:61:9c:75:80 oper key: 6 port priority: 32768 port number: 293 port state: 61 Slave Interface: ens2f3 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 2 Permanent HW addr: 48:df:37:0c:7f:5b Slave queue ID: 0 Aggregator ID: 5 Actor Churn State: none Partner Churn State: none Actor Churned Count: 0 Partner Churned Count: 3 details actor lacp pdu: system priority: 65535 system mac address: 48:df:37:0c:7f:5a port key: 9 port priority: 255 port number: 2 port state: 61 details partner lacp pdu: system priority: 32768 system mac address: b8:38:61:9c:75:80 oper key: 6 port priority: 32768 port number: 549 port state: 61 Also, the other node (that is currently in maintenance) shows one of the 2 interfaces of bond2 (ens2f2) as down (red arrow) but on the host # ip link show ens2f2 6: ens2f2: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc mq master bond2 state UP mode DEFAULT qlen 1000 link/ether 48:df:37:0c:85:4e brd ff:ff:ff:ff:ff:ff # Does this depend on the host being in maintenance? Perhaps when a host is in maintenance, the warnings on it are not checked/updated again from engine? Thanks in advance, Gianluca

Unable to grant permissions to AD users
by Michael Watters 06 Oct '17

06 Oct '17

I'm having some issues granting permissions to AD users in ovirt-engine 4.1. Users can log in but receive an error as below. The user user@example.com@example.com is not authorized to perform login I am also not able to grant this user any permissions through the admin console. Entering a user name in the search field for the System Permissions section results in a blank list. Attached is a screenshot for reference. Does anybody have an idea on what would cause this? The log files aren't very useful and don't show any errors.

by codignotto . 06 Oct '17

06 Oct '17

Good night friends, I'm trying to make the passtrought GPU run using OVIRT with an NVIDIA M2000 / K2200 and a K4000, I made several configurations, the VM with windows recognizes the card, I install the NVIDIA drivers and after restarting the windows and access using the client SPICE remote viwer the mouse to work, everything works because the mouse does not work for anything, already tested with Win8, Win10 and the problem persists, the card is recognized but the mouse does not work. Has anyone used it this way? Passtrought from GPU to a VM using SPICE? I'm going to use these clients with 3d and adobe products. Thank you for your help Deny

IOPS stats/reports from all hosts to storage
by Neil 05 Oct '17

05 Oct '17

Hi guys, I'm running FC storage with 4 hosts on oVirt 3.6 and we've been having some IOPS issues recently and the SAN provider has asked me to provide them with the following info... Datastore Stripe Size Default VM Disk Stripe Size Average IO Size Average THROUGHPUT (MB/s) Average IOPS Maximum IOPS Read/Write Percentage of IO Datastore Average Latency VM Disk Average Latency All of this is from across all hosts and VM's to the storage domain. Is there any way to get this kind of info from oVirt? I've been looking at oVirt-reports but I don't see much as far as IO/throughput reporting goes. Apologies if I've missed something obvious. Thanks. Regards. Neil Wilson.

LVM structure

Hello, I'm still coping with my qemu image corruption, and I'm following some Redhat guidelines that explains the way to go : - Start the VM - Identify the host - On this host, run the ps command to identify the disk image location : # ps ax|grep qemu-kvm|grep vm_name - Look for "-drive file=/rhev/data-center/00000001-0001-0001-0001-00000000033e/b72773dc-c99c-472a-9548-503c122baa0b/images/91bfb2b4-5194-4ab3-90c8-3c172959f712/e7174214-3c2b-4353-98fd-2e504de72c75" (YMMV) - Resolve this symbolic link # ls -la /rhev/data-center/00000001-0001-0001-0001-00000000033e/b72773dc-c99c-472a-9548-503c122baa0b/images/91bfb2b4-5194-4ab3-90c8-3c172959f712/e7174214-3c2b-4353-98fd-2e504de72c75 lrwxrwxrwx 1 vdsm kvm 78 3 oct. 2016 /rhev/data-center/00000001-0001-0001-0001-00000000033e/b72773dc-c99c-472a-9548-503c122baa0b/images/91bfb2b4-5194-4ab3-90c8-3c172959f712/e7174214-3c2b-4353-98fd-2e504de72c75 -> /dev/b72773dc-c99c-472a-9548-503c122baa0b/e7174214-3c2b-4353-98fd-2e504de72c75 - Shutdown the VM - On the SPM, activate the logical volume : # lvchange -ay /dev/b72773dc-c99c-472a-9548-503c122baa0b/e7174214-3c2b-4353-98fd-2e504de72c75 - Verify the state of the qemu image : # qemu-img check /dev/b72773dc-c99c-472a-9548-503c122baa0b/e7174214-3c2b-4353-98fd-2e504de72c75 - If needed, attempt a repair : # qemu-img check -r all /dev/... - In any case, deactivate the LV : # lvchange -an /dev/... I followed this steps tens of times, and finding the LV and activating it was obvious and successful. Since yesterday, I'm finding some VMs one which these steps are not working : I can identify the symbolic link, but the SPM neither the host are able to find the LV device, thus can not LV-activate it : # lvchange -ay /dev/de2fdaa0-6e09-4dd2-beeb-1812318eb893/ce13d349-151e-4631-b600-c42b82106a8d Failed to find logical volume "de2fdaa0-6e09-4dd2-beeb-1812318eb893/ce13d349-151e-4631-b600-c42b82106a8d" Either I need two more coffees, either I may be missing a step or something to check. Looking at the SPM /dev/disk/* structure, it looks like very sound (I can see my three storage domains dm-name-* series of links). As the VM can nicely be ran and stopped, does the host activates something more before being launched? -- Nicolas ECARNOT

Organizing an event of oVirt in Myanmar
by Yan Naing Myint 05 Oct '17

05 Oct '17

Hello, We have planned an event named "The Tech Talk" on October 15, 2017. In the event we will mainly focus on - oVirt Virtualization - RAID & NFS - iSCSI In the event, we will use CentOS as main Linux distribution on which above mentioned services will be installed. The event is originally organized by Cyber Wings Co., Ltd here in Yangon, Myanmar. oVirt Myanmar Community is in association with them. Yet as a part of the event, I'm somehow promoting the oVirt alternatively.

Ovirt causing strange network issues?
by Derek Atkins 05 Oct '17

Hi, I'm at my wits end so I'm tossing this here in the hopes that SOMEONE will be able to help me. tl;dr: Ovirt is doing something on my network that is causing my fiber modem to go from 3-5ms to 300-1000+ms round trip times. I know it's ovirt because when I unplug ovirt from my network the issue goes away; when I plug it back in, the issue recurs. Long version: I've been running Ovirt 4.0.6 happily on CentOS 7.3 for several months on a single host machine. Indeed, the host had an uptime of 200+ days and was working great until approximately midnight, September 21/22 (just over a week ago). I was on an airplane halfway across the Atlantic at that time, so it wasn't anything I did. My network is configured as: fiber modem <-> edgerouter <-> switch <-> everything else ovirt is living in the "everything else" area. When I sit with a laptop connected to either the everything else range or even directly connected to the fiber modem, I run 'mtr' and see network times (starting at the fiber modem) that bounce all over the place. When I unplug ovirt I see consistent 3-5ms times. Plug it back in, voom, back up to badness. I've spent several hours plugging and unplugging different devices trying to isolate the issue. The only "device" that has any effect is my ovirt box. I have tried to debug this in several ways, but really the only thing that seems to have helped at all is shutting down all the VMs and the hosted engine. Once nothing else is running (but the host itself), only then does the network seem to return to normal. I'm really at my wits end on this; I have no idea what is causing this or what might have changed to cause the issue right at that time. I also can't imagine what ovirt is doing over the network that could cause the modem, two physical hops away, to lose its mind in this way. But my experiementation is definitely showing a direct correlation. Help!! -derek -- Derek Atkins 617-623-3745 derek(a)ihtfp.com www.ihtfp.com Computer and Internet Security Consultant
