[4.3.0] VNC Virt-viewer console not opening
by Nicolas Ecarnot 05 Feb '19

05 Feb '19

Hello, First, congratulations to all of you who worked for this 4.3.0 release, and obviously thank you. Today, I upgraded 4 oVirt setups (4 DC) from 4.2.7 to 4.3.0. I went well on all 4 DCs. But on one of them, when I try to open a console, I see it open as a flash (it opens and closes immediately). I'm using Firefox 64.0 with Ubuntu 18.10, and all my VMs are setup like this : - video type : QXL - Gfx protocol : VNC - VNC Kbd layout : fr and I'm using virt-viewer On the problematic DC, all the VMs are showing the same issue. When I try to use Spice instead of VNc, it is working nicely. When I try to use noVNC, the additional tab opens and shows "Unsupported security types: 19" I tried to track down this issue thanks to the firefox dev console, but it's beyond my understanding. Trying the same with Chromium does the same blinking open/close. I'd rather learn how to provide additionnal debug messages, but /var/log/ovirt-engine/engine.log does not give any useful hint : 2019-02-04 16:57:04,150+01 INFO [org.ovirt.engine.core.bll.SetVmTicketCommand] (default task-24) [1fb01d42] Running command: SetVmTicketCommand internal: false.

Upgrade guide for node from 4.2->4.3
by Juhani Rautiainen 05 Feb '19

05 Feb '19

Hi! Thanks for the new release. I managed to upgrade the engine from 4.2->4.3 with old upgrade instructions but I'm having problems with 4.2 node upgrades. Adding repos with ovirt-release43 doesn't allow node upgrade. Lot's of missing dependencies. Dpdk depencies could be solved with adding Centos Extras, but what repo you should use for openscap, openscap-utils and scap-security-guide packages? -Juhani

Ovirt cluster unstable; gluster to blame (again)
by Jim Kusznir 04 Feb '19

04 Feb '19

hi all: Once again my production ovirt cluster is collapsing in on itself. My servers are intermittently unavailable or degrading, customers are noticing and calling in. This seems to be yet another gluster failure that I haven't been able to pin down. I posted about this a while ago, but didn't get anywhere (no replies that I found). The problem started out as a glusterfsd process consuming large amounts of ram (up to the point where ram and swap were exhausted and the kernel OOM killer killed off the glusterfsd process). For reasons not clear to me at this time, that resulted in any VMs running on that host and that gluster volume to be paused with I/O error (the glusterfs process is usually unharmed; why it didn't continue I/O with other servers is confusing to me). I have 3 servers and a total of 4 gluster volumes (engine, iso, data, and data-hdd). The first 3 are replica 2+arb; the 4th (data-hdd) is replica 3. The first 3 are backed by an LVM partition (some thin provisioned) on an SSD; the 4th is on a seagate hybrid disk (hdd + some internal flash for acceleration). data-hdd is the only thing on the disk. Servers are Dell R610 with the PERC/6i raid card, with the disks individually passed through to the OS (no raid enabled). The above RAM usage issue came from the data-hdd volume. Yesterday, I cought one of the glusterfsd high ram usage before the OOM-Killer had to run. I was able to migrate the VMs off the machine and for good measure, reboot the entire machine (after taking this opportunity to run the software updates that ovirt said were pending). Upon booting back up, the necessary volume healing began. However, this time, the healing caused all three servers to go to very, very high load averages (I saw just under 200 on one server; typically they've been 40-70) with top reporting IO Wait at 7-20%. Network for this volume is a dedicated gig network. According to bwm-ng, initially the network bandwidth would hit 50MB/s (yes, bytes), but tailed off to mostly in the kB/s for a while. All machines' load averages were still 40+ and gluster volume heal data-hdd info reported 5 items needing healing. Server's were intermittently experiencing IO issues, even on the 3 gluster volumes that appeared largely unaffected. Even the OS activities on the hosts itself (logging in, running commands) would often be very delayed. The ovirt engine was seemingly randomly throwing engine down / engine up / engine failed notifications. Responsiveness on ANY VM was horrific most of the time, with random VMs being inaccessible. I let the gluster heal run overnight. By morning, there were still 5 items needing healing, all three servers were still experiencing high load, and servers were still largely unstable. I've noticed that all of my ovirt outages (and I've had a lot, way more than is acceptable for a production cluster) have come from gluster. I still have 3 VMs who's hard disk images have become corrupted by my last gluster crash that I haven't had time to repair / rebuild yet (I believe this crash was caused by the OOM issue previously mentioned, but I didn't know it at the time). Is gluster really ready for production yet? It seems so unstable to me.... I'm looking at replacing gluster with a dedicated NFS server likely FreeNAS. Any suggestions? What is the "right" way to do production storage on this (3 node cluster)? Can I get this gluster volume stable enough to get my VMs to run reliably again until I can deploy another storage solution? --Jim

One disk in illegal state after deleting snapshot with several disks
by Florian Schmid 04 Feb '19

04 Feb '19

Hi, I'm using oVirt 4.2.5. I know, it is not the newest anymore, but our cluster is quite big and I will upgrade to 4.2.8 as soon as possible. I have a VM with several disks, one with virtio (boot device) and 3 other disks with virtio-scsi: log 8190c797-0ed8-421f-85c7-cc1f540408f8 1 GiB root 5edab51c-9113-466c-bd27-e73d4bfb29c4 10 GiB tmp 11d74762-6053-4347-bdf2-4838dc2ea6f0 1 GiB web_web-content bb5b1881-d40f-4ad1-a8c8-8ee594b3fe8a 20 GiB Snapshots where quite small, because not much is changing there. All disks are on NFS v3 share running on NetApp cluster. Some IDs: VM ID: bc25c5c9-353b-45ba-b0d5-5dbba41e9c5f affected disk ID: 6cbd2f85-8335-416f-a208-ef60ecd839a4 Snapshot ID: c8103ae8-3432-4b69-8b91-790cdc37a2da Snapshot disk ID: 2564b125-857e-41fa-b187-2832df277ccf Task ID: 2a60efb5-1a11-49ac-a7f0-406faac219d6 Storage domain ID: 14794a3e-16fc-4dd3-a867-10507acfe293 After triggering snapshot delete task (2a60efb5-1a11-49ac-a7f0-406faac219d6), deletion was running for about one hour and I though it was hanging and I restarted the engine process on self-hosted engine... After that, snapshot was still in lock state, therefore, I deleted the lock: /usr/share/ovirt-engine/setup/dbutils/unlock_entity.sh -t snapshot c8103ae8-3432-4b69-8b91-790cdc37a2da ########################################## CAUTION, this operation may lead to data corruption and should be used with care.

I have umounted the disk inside the VM, after I saw, that the snapshot disk is still in use. That's why, the date is not changed anymore. The strange thing is, that it looks like that the merge was working for a short time, because also time of the underlying disk has changed... In database, I have this data about the VM and its snapshot: engine=# select snapshot_id,snapshot_type,status,description from snapshots where vm_id='bc25c5c9-353b-45ba-b0d5-5dbba41e9c5f'; snapshot_id | snapshot_type | status | description --------------------------------------+---------------+--------+------------- f596ba1c-4a6e-4372-9df4-c8e870c55fea | ACTIVE | OK | Active VM c8103ae8-3432-4b69-8b91-790cdc37a2da | REGULAR | OK | cab-3449 engine=# select image_guid,parentid,imagestatus,vm_snapshot_id,volume_type,volume_format,active from images where image_group_id='8190c797-0ed8-421f-85c7-cc1f540408f8'; image_guid | parentid | imagestatus | vm_snapshot_id | volume_type | volume_format | active --------------------------------------+--------------------------------------+-------------+--------------------------------------+-------------+---------------+-------- 2564b125-857e-41fa-b187-2832df277ccf | 6cbd2f85-8335-416f-a208-ef60ecd839a4 | 1 | f596ba1c-4a6e-4372-9df4-c8e870c55fea | 2 | 4 | t 6cbd2f85-8335-416f-a208-ef60ecd839a4 | 00000000-0000-0000-0000-000000000000 | 4 | c8103ae8-3432-4b69-8b91-790cdc37a2da | 2 | 5 | f vdsm-tool dump-volume-chains 14794a3e-16fc-4dd3-a867-10507acfe293: image: 8190c797-0ed8-421f-85c7-cc1f540408f8 - 6cbd2f85-8335-416f-a208-ef60ecd839a4 status: OK, voltype: INTERNAL, format: RAW, legality: LEGAL, type: SPARSE - 2564b125-857e-41fa-b187-2832df277ccf status: OK, voltype: LEAF, format: COW, legality: LEGAL, type: SPARSE @bzlotnik, it would be great, when you can help me to get the disk back only without stopping or starting the VM. I'm really afraid now of deleting snapshots... I will send you the vdsm log from host running the VM and from SPM and engine.log. Thank you very much! BR Florian Schmid

Wrong CPU performance report
by Hetz Ben Hamo 04 Feb '19

04 Feb '19

Hi, I'm running oVirt 4.2.7.1. I installed Windows 10 pro as a guest, along with QXL and all the drivers, as well as QEMU guest agent. While Windows reports a CPU usage of something like 2-4% when idle, oVirt reports 24-27% CPU usage. Bug? should I report it? Thanks

oVirt can't communicate with vSphere
by Benjamin Selinger 03 Feb '19

03 Feb '19

Trying to get my ovirt cluster connected to my vSphere cluster to import my guests. When trying to connect, I get: "VDSM ovirt1 command GetVmsNamesFromExternalProviderVDS failed: internal error: curl_easy_perform() returned an error: Couldn't connect to server (7) : Failed connect to 10.0.0.55:443; Connection timed out" ovirt1 node (192.168.1.195) is at location A while vSphere (10.0.0.55) is at location B. I added a static route on ovirt1 for 10.0.0.0/8 via 192.168.1.13, which has a VPN connection back to 10.0.0.0/8. ICMP from ovirt1 gets through just fine, but any other traffic never leaves ovirt1 (ie: 443 traffic never arrives at 1.13). I'm assuming there's some firewall rule somewhere, blocking anything other than outbound ICMP, but I have been unable to find it. Any suggestions?

Windows 10 - Ovirt 4.3 - EPYC
by Darin Schmidt 01 Feb '19

01 Feb '19

I have successfully setup a centos vm, its up and running. Now I need to setup a windows 10 VM and I cant seem to get anything to work. Ive tried setting the OS type to other or Windows 10 64bit. With Windows 64bit, it fails to startup at all.... When I select OtherOS it will allow me to start to run the Windows ISO, but then fails after a few seconds as well. Is there something I'm not correctly configuring?

Mounting ISO in subfolder
by Giulio Casella 01 Feb '19

01 Feb '19

Hi, I noticed that if I create a directory in root of ISO domain and put an image in it, you can see it in admin portal image list (listed as "foo/bar.iso"), but mounting that iso in a VM ("change CD") fails "Error while executing action Change CD: Drive image file could not be found" I can easily reproduce this behaviour in ovirt 4.2.8 and rhv 4.2.7. Is it a bug? Cheers, gc
