Hosted Engine Deploy kernel panics on boot
by Karli Sjöberg 26 Jul '18

Hey all! 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.

Raid configuration for single instance
by Leo David 25 Jul '18

25 Jul '18

Hello everyone, Based on your experiance or well know best practices can you provide me with an advice on raid configuration ? I have a single server, that will have a couple of brand new enterprise grade ssds, spinning and one pci nvme card. The server ( Dell PE r630 ) comes wirt Perc h730p raid controller with 2gb cache. I am thinking of creating a raid 1 array with the 2 of ssd's and ne raid10 array woth the rest of for spinning hdds. Then different gluster volume on each, to provide me 2 ( ssd / sata ) storage domains. What do you think on haveing raid1 / raid10 as underlying HA storage for gluster volumes ? At the moment a have some consumer devices ( samsung evo & seagate spinning shingled type ) and about every day the vms get into "VM has been paused due to storage IO errors" - i am thinking because of bad type hdds. Any thoughts on these ? Thank you , Leo -- Best regards, Leo David
