NFS Storage Advice?
by Wesley Stewart 28 Jul '18

28 Jul '18

I currently have a NFS server with decent speeds. I get about 200MB/s write and 400+ MB/s read. My single node oVirt host has a mirrored SSD store for my Windows 10 VM, and I have about 3-5 VMs running on the NFS data store. However, VM/s on the NFS datastore are SLOW. They can write to their own disk around 10-50 MB/s. However a VM on the mirrored SSD drives can get 150-250 MB/s transfer speed from the same NFS storage (Through NFS mounts). Does anyone have any suggestions on what I could try to speed up the NFS storage for the VMs? My single node ovirt box has a 1ft Cat6 crossover cable plugged directly into my NFS servers 10GB port. Thanks!

Spice console pixelated noise on display changes
by Mitja Mihelič 28 Jul '18

28 Jul '18

Dear all, We are running the following setup: ovirt-engine host: - CentOS release 7.5.1804 - ovirt-engine-4.1.9.1-1.el7.centos.noarch - spice-html5-0.1.7-1.el7.noarch We have noticed problems with the Spice console. When it opens and displays the information presented by the VM's console it is OK at first. But as soon as any part of the display changes, that part gets replaced by random pixelated noise. For example I open the console of a standard CentOS server. When I type something at the login prompt the text is invisible and random pixels are displayed at the position of the blinking cursor. Please see attached screenshot spice-1-login_typing_and_cursor_waiting.png. Please also see other the attached screenshots. Login prompt after VM reboot: spice-2-login_after_boot.png Login prompt after hitting Enter a few times: spice-3-login_2x_enter.png We have tried and succesfully reproduced the issue on OSX (Chrome, FF, Safari) and Windows (Chrome, FF). VNC works fine. Why would this be happening? Help would be very much appreciated. Kind regards, Mitja -- Mitja Mihelič ARNES, Tehnološki park 18, p.p. 7, SI-1001 Ljubljana, Slovenia tel: +386 1 479 8877, fax: +386 1 479 88 7

Understanding JBOD brick configuration
by Jayme 27 Jul '18

27 Jul '18

I'm deploying three host Ovirt HCI and I'm a bit confused about how to configure the glusterFS volumes and bricks in the cockpit. My three hosts are configured the exact same way physically: 2x250GB SSDs in Raid 1 for OS 2 x 2TB SSD in JBOD which I intend to use for Gluster (devices sda and sdb) So on Step 3 (Volumes) of gluster deployment I'm leaving the volumes default (with no arbiter as I want replica 3). So that is creating a volume for Engine, Data and VMstore On step 4 (Bricks) I'm choosing jbod and next is where I'm getting confused. I have to specify the device name and size for each volume. It appears that I have to break up sda and sdb devices here. I have 4 TB total between the two JBOD drives but does that mean I can only specify up to 2TB usable for the data volume (on either sda or sdb) then split the space on the second 2TB drive between engine and vmstore? If so this seems like an awful waste of a 2TB drive for use for only engine and vmstore volumes. With my JBOD configuration of two separate disks per hosts is there any way I can have a data volume use most of that space say 3.5TB and the rest goes to engine/vmstore? It was my understanding that glusterFS would pool all available space together and I could use it however I wanted. Can I achieve this without putting the 2TB disks in to a raid configuraiton? Thanks!

trunked ports
by william.dossett＠gmail.com 27 Jul '18

27 Jul '18

Hi, I setup oVirt a few years back. now that the HCI is real, I am revisiting it. I have deployed with Gluster, and am now moving on to networking. I come from a VMware shop and normally we trunk all the network ports exposing all VLANs to the hosts and place VMs in Portgoups that are tagged with VLANs. I did manage to do this years back but I am struggling to get this to work today. I had pretty limited hardware back then and I thought I installed using vlan tagging and trunked ports, but I don't see any option to do this using the glusterfs and hosted engine setup. Each host has a dual port 10Gb NICs I use one for storage that is connected to my storage network and one for ovirtmgmt. (I need to add another of these for redundancy down the road, but no money for that at the moment) The hosts also have 4 x 1Gb ports. So in lieu of being able to configure vlan tagging to trunked ports on hosted engine deploy, I am considering cabling up a 1 Gb port on each in my management services VLAN and when it is all up and running create another logical network (or several of them as I think these equate to what is a vlan tagged port group in VMware) with the 10Gb NIC backing for VMs. Does that sound reasonable? Or if anyone can point me to any docs that describe how to deploy to a specific VLAN with trunk ports, that would be nice as well as I won't have to actually go to the office and run additional cables. Appreciate any advice Bill

Do you need to format/mount bricks before deploying HCI?
by Jayme 27 Jul '18

27 Jul '18

I'm building a 3 host HCI configuration. I have servers configured and latest version of oVirt node 4.2 installed. I'm preparing to run the cockpit hosted engine + glusterFS deploy. Each of my hosts have two SSDs in JBOD /dev/sda and /dev/sdb Currently these drives have not been touched, formatted or mounted. Is this required before continuing with the deploy, or will the deploy script format and mount the drives accordingly? Thanks!

I'm trying to deploy Hosted Engine through the Cockpit UI and it's going well until it's time to start the local VM and it kernel panics: [ 2.032053] Call Trace: [ 2.032053] [<ffffffffb687e78c>] load_elf_binary+0x33c/0xe50 [ 2.032053] [<ffffffffb68f3919>] ? ima_bprm_check+0x49/0x50 [ 2.032053] [<ffffffffb687e450>] ? load_elf_library+0x220/0x220 [ 2.032053] [<ffffffffb682236f>] search_binary_handler+0xef/0x310 [ 2.032053] [<ffffffffb6823b4b>] do_execve_common.isra.24+0x5db/0x6e0 [ 2.032053] [<ffffffffb6823c68>] do_execve+0x18/0x20 [ 2.032053] [<ffffffffb66afc1f>] ____call_usermodehelper+0xff/0x140 [ 2.032053] [<ffffffffb66afb20>] ? call_usermodehelper+0x60/0x60 [ 2.032053] [<ffffffffb6d20677>] ret_from_fork_nospec_begin+0x21/0x21 [ 2.032053] [<ffffffffb66afb20>] ? call_usermodehelper+0x60/0x60 [ 2.032053] Code: cf e9 ff 4c 89 f7 e8 7b 32 e7 ff e9 4d fa ff ff 65 8b 05 03 a0 7e 49 a8 01 0f 84 85 fc ff ff 31 d2 b8 01 00 00 00 b9 49 00 00 00 <0f> 30 0f 1f 44 00 00 48 c7 c0 10 00 00 00 e8 07 00 00 00 f3 90 [ 2.032053] RIP [<ffffffffb6823025>] flush_old_exec+0x725/0x980 [ 2.032053] RSP <ffff8add75ecbd00> [ 2.298131] ---[ end trace 354b4039b6fb0889 ]--- [ 2.303914] Kernel panic - not syncing: Fatal exception [ 2.304835] Kernel Offset: 0x35600000 from 0xffffffff81000000 (relocation range: 0xffffffff80000000-0xffffffffbfffffff) I've never had this problem so I'd just want to know if it's a known issue right now or if I've done anything special to deserve this:) The "Hosts" I'm deploying this on are VMs with nested virt activated, and I've done this before but this time around it's bombing, as earlier explained. Thanks in advance! /K

Q: Power failure - proper data center shutdown procedure
by Andrei Verovski 26 Jul '18

26 Jul '18

Hi, I have the following simple setup: oVirt engine - 4.2.3 (running as KVM appliance on SuSE Linux) node1.1 - 4.2.1 (installed with clean CentOS and newer elrepo 4.15.4-1el1 kernel) node1.2 - 4.2.3 (installed with clean CentOS and newer elrepo 4.16.2-1el7 kernel) VMs - Debian, CentOS, and Windows guests, with ovirt-agent installed (except one with Linux telephony software). What is the proper shutdown procedure in case of power failure? I have simple scripts which simply run “shutdown now” on each host after 10 min. However, oVirt nodes fail to shutdown properly, process take about 25 minutes. node1.2 libvirt-guests.sh[10696]: Waiting for guest GUEST_VM_NAME to shut down node1.1 - these processes took VERY LONG time: Unmounting /rhev/data-center/mnt/node11.mydomain.com:_vm_raid_nfs_export… Unmounting /rhev/data-center/mnt/node12.mydomain.com:_vm_raid_nfs_disks… Unmounting /rhev/data-center/mnt/node11.mydomain.com:_vm_raid_nfs_disks… Unmounting /rhev/data-center/mnt/node11.mydomain.com:_vm_raid_nfs_iso… on both nodes: [] Forcibly powering off: job timed out as result, OS is down, server is not, still drawing power from UPS battery. Powering on was problematic, I had to restart node11 2nd time before it becomes “green” in oVirt engine. One VM failed to start with error message “Can’t acquire ticket” and struck with grey arrows (with no possibilty to make anything) - unfortunately, I forgot to take screenshot or record exact message. Restarting node1.1 cured that problem. Q: what is proper oVirt data center automatic shutdown procedure? Thanks in advance Andrei

Uncaught exception occurred - NS_ERROR_FILE_CORRUPTED
by Michael Seidel 26 Jul '18

26 Jul '18

Hi, I am running oVirt in version 4.2 and just started getting this error message upon login: Uncaught exception occurred. Please try reloading the page. Details: (NS_ERROR_FILE_CORRUPTED) : Please have your administrator check the UI logs The relevant content of the ui.log is given below (or, nicely formatted at https://paste.ee/p/LUrbt) I am able to access the js file directly using a browser so the file is definitely not missing and is readable. However, the side-bar of the ovirt webadmin is not showing (or more precisely: it loads and shows for a split-second and then disappears). The Web Console shows a similar error message as the one below, referring to the same js file and in addition says: Tue Jul 24 14:28:03 GMT+200 2018 com.gwtplatform.mvp.client.presenter.slots.LegacySlotConvertor SEVERE: Warning: You're using an untyped slot! Untyped slots are dangerous! Please upgrade your slots using the Arcbee's easy upgrade tool at https://arcbees.github.io/gwtp-slot-upgrader The github-URL however is not working. I also upgraded and rebooted the ovirt engine, but the error remains. Do you have any suggestions what might cause this issue and how I can fix it.

Self hosted to bare metal engine
by Christophe TREFOIS 25 Jul '18

25 Jul '18

Hi, What would be the process to go from self hosted engine to bare metal engine? (Actually it would move to a VM in a VMware cluster) All user guides I found are from bare metal to self hosted. Thanks for any tips or pointers Christophe Sent from my iPhone

Cannot switch to maintenance, image transfer is in progress
by Randy Bender 25 Jul '18

25 Jul '18

We've just updated our hosted engine to 4.2.4. When trying to place one of the hosts in maintenance mode, we get the error in the subject line. I've found the following that looks to be the issue we are hitting: https://bugzilla.redhat.com/show_bug.cgi?id=1586126 I've looked in the engine database with the following command and results: engine=# select disk_id from image_transfers ; disk_id -------------------------------------- 52966b71-2d01-4a16-9830-65a888717656 c72d64b7-93c9-485b-b031-29c785c5bf9a (2 rows) Full details on these records show that they are indeed old - there are no transfers actually in progress. Can anyone confirm the correct way to remedy this? The bug report notes changing the phase on the record in question. Before I try that, I'd like confirmation if anyone else has seen this issue and resolved it. And if this is the resolution, can you describe the exact psql commands to achieve this? Thanks

Freshly installed ovirt-node-ng 4.2.4 unable to deploy hosted-engine
by Ralf Schenk 25 Jul '18

25 Jul '18

Hello List, after having freshly installed my first ovirt-node-ng 4.2.4 configuring basic networking and preparing NFS Shares on my NFS-Server I would like to deploy hosted engine on this first host and NFS Storage. In Cockpit I set Performance Profile to "virtual host" and mounted an export from my Sotrage as /mnt/engine (Which shouldn't be needed since I expected the engine-setup wizard to ask me...) I'm, already stuck when selecting "Hosted Engine Deploy oVirt hosted engine on storage that has already been provisioned": save image "hosted-engine-setup" on the command-line is not available. Furthermore I've warnings in Node Health Status. I didn't configure discard anywhere. It is used as it was set up by the installer on the logical volumes residing on a SATA Disk. save image save image -- *Ralf Schenk* fon +49 (0) 24 05 / 40 83 70 fax +49 (0) 24 05 / 40 83 759 mail *rs(a)databay.de* <mailto:rs@databay.de> *Databay AG* Jens-Otto-Krag-Straße 11 D-52146 Würselen *www.databay.de* <http://www.databay.de> Sitz/Amtsgericht Aachen • HRB:8437 • USt-IdNr.: DE 210844202 Vorstand: Ralf Schenk, Dipl.-Ing.

interface up when not used
by Fabrice Bacchella 25 Jul '18

25 Jul '18

To monitoring the network interfaces, I have a script that check if ifAdminStatus and ifOperStatus values matches in snmp. But with oVirt it fails on a server with 4 physical interfaces, but only two connected, and return an error: snmptable XXX IF-MIB::ifTable | less SNMP table: IF-MIB::ifTable ifIndex ifDescr ifAdminStatus ifOperStatus 1 lo up up 2 eth0 up up 3 eth1 up up 4 eth2 up down 5 eth3 up down 24 ;vdsmdummy; down down 25 vnet0 up up And indeed on the server: ip link show eth2 4: eth2: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000 link/ether 40:a8:f0:30:81:1a brd ff:ff:ff:ff:ff:ff It's up, but I don't configured it on oVirt, removed ifcg-eth2. Is there a way to disable it ?

Sync LDAP users in Ovirt
by Hari Prasanth Loganathan 25 Jul '18

25 Jul '18

Hi Team, Good Morning. I configured the ovirt with LDAP setup. Is there an *oVirt tool* (or any way) to add all the users from LDAP to Ovirt? *Observation* : 1) I am able to see that when I try to login with the user from LDAP, that user is added in Ovirt database, So Is there a way to sync all the users from LDAP to Ovirt using any oVirt tool or API? Any help is much appreciated.
