Bad volume specification
by Rodrick Brown 06 Jan '17

06 Jan '17

I'm using gluster/zfs for the backing store on my Ovirt VM's its seems our gluster volume may have ran low on space and a few VM's we're paused due to long i/o wait times. I'm no longer able to bring these VM's back online because I get the following error: OSError: [Errno 22] Invalid argument Thread-991494::ERROR::2017-01-06 01:17:32,990::vm::759::virt.vm::(_startUnderlyingVm) vmId=`add4f65a-6389-4fc8-bf9d-bf92964cecf0`::The vm start process failed Traceback (most recent call last): File "/usr/sha StorageUnavailableError: Unable to get volume size for domain domain XXXX volume XXXX I have snapshots is their anyway I can recover or fix this issue?

Modifying the main /ovirt-engine/ landing page -- add link to CA Cert?
by Derek Atkins 05 Jan '17

05 Jan '17

Hi, I'd like to make some modifications to the main /ovirt-engine/ landing page that I (and my users) hit when then first connect to my server. Specifically, I want to add another link under the "Downloads" section to the ovirt CA certificate to make it much easier to download: <a href="/ovirt-engine/services/pki-resource?resource=ca-certificate&format=X509-PEM-CA">Ovirt CA Certificate</a> However I can't find the HTML for this page, and any links I've found seem to refer back to 3.x locations and not anything for 4.0.5. Where can I find the HTML for this landing page, or how can I get this link added? I presume I'll have to modify the page every time I update the engine, too. Thanks, -derek -- Derek Atkins 617-623-3745 derek(a)ihtfp.com www.ihtfp.com Computer and Internet Security Consultant

OVF disk errors
by Michael Watters 05 Jan '17

05 Jan '17

Hello, I have two hosts in a cluster running ovirt 3.6 and I keep seeing errors in the event log as follows. Jan 5, 2017 2:34:01 PM Host ovirt-node-production2 power management was verified successfully. Jan 5, 2017 2:34:01 PM Status of host ovirt-node-production2 was set to Up. Jan 5, 2017 2:33:58 PM Executing power management status on Host ovirt-node-production2 using Proxy Host ovirt-node-production1 and Fence Agent ipmilan:1.2.3.4 Jan 5, 2017 2:33:48 PM Failed to update OVF disks c7c567a3-ebd5-4e3a-bf1e-66080e8a09b4, OVF data isn't updated on those OVF stores (Data Center Default, Storage Domain 2-Production-Faster). Jan 5, 2017 2:33:47 PM Host ovirt-node-production2 is not responding. It will stay in Connecting state for a grace period of 104 seconds and after that an attempt to fence the host will be issued. Jan 5, 2017 2:33:47 PM Failed to update OVF disks 389bd0fe-804c-428d-9de1-640d83fe9a29, OVF data isn't updated on those OVF stores (Data Center Default, Storage Domain 1-Production-Slower). Jan 5, 2017 2:33:42 PM VDSM ovirt-node-production2 command failed: Logical Volume extend failed What concerns me the most is the last two errors. I've verified that all disks are online and all volume groups are working as expected. Is there a way to manually update an OVF disk? Here is what the engine database shows for these disk IDs. engine=# select * from storage_domains_ovf_info where ovf_disk_id = 'c7c567a3-ebd5-4e3a-bf1e-66080e8a09b4' ; storage_domain_id | status | ovf_disk_id | stored_ovfs_ids | last_updated --------------------------------------+--------+--------------------------------------+-----------------+---------------------------- 32f7c737-c1ee-4d2e-82a7-1b5e6efe0cf8 | 1 | c7c567a3-ebd5-4e3a-bf1e-66080e8a09b4 | | 2016-11-21 13:48:55.756-05 (1 row) engine=# select * from storage_domains_ovf_info where ovf_disk_id = '389bd0fe-804c-428d-9de1-640d83fe9a29' ; storage_domain_id | status | ovf_disk_id | stored_ovfs_ids | last_updated --------------------------------------+--------+--------------------------------------+-----------------+---------------------------- 52e48bb6-e477-41fe-aa25-69fc04b47c98 | 1 | 389bd0fe-804c-428d-9de1-640d83fe9a29 | | 2016-12-31 00:13:58.924-05 (1 row)

Hosted Engine does no detect GlobalMaintenaceMode set from other host 4.0.4- > 4.0.5
by Matt . 05 Jan '17

05 Jan '17

Hi Guys, Why updating my hosted-engine from 4.0.4 to 4.0.5 I have set my cluster into GlobalMaintenaceMode from HE host 1 where the engine was running on HE host 4. All hosts reported a GlobalMaintenaceMode on --vm-status but the hosted-engine didn't want to upgrade because it didn't see this GlobalMaintenaceMode. After setting --set-maintenance --mode=global on HE host 4 the hosted-engine saw the GlobalMaintenanceMode and the upgrade went further. Is this a bug maybe ? Regards, Matt

Video performance

05 Jan '17

Hi, I have installed ovirt engine 4.0.5 on centos 7.3. I installed ovirt-node on a separate phyical system and added it to ovirt-engine. I installed windows 7 in a VM on the node. I installed all the virtio drivers in the guest. The protocol used by me to access VM is Spice QXL. I have installed virt-viewer on the clients to access (one is windows and othe ris ubuntu) Now, when I pay the sample video "wildlife" in the windows the video frame rate is very low and it is skipping a aot of frames. I tested it on both of the clients. The screen resolution is 1280x1024 on ubuntu and 1366x768 on windows. The *lscpu* output of the node is: Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 48 On-line CPU(s) list: 0-47 Thread(s) per core: 2 Core(s) per socket: 12 Socket(s): 2 NUMA node(s): 2 Vendor ID: GenuineIntel CPU family: 6 Model: 62 Model name: Intel(R) Xeon(R) CPU E5-2697 v2 @ 2.70GHz Stepping: 4 CPU MHz: 3047.097 BogoMIPS: 5406.43 Virtualization: VT-x L1d cache: 32K L1i cache: 32K L2 cache: 256K L3 cache: 30720K NUMA node0 CPU(s): 0-11,24-35 NUMA node1 CPU(s): 12-23,36-47 The top command output is showing the following on the node: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 30219 qemu 20 0 5040176 4.048g 13564 S 113.2 3.2 16:05.49 qemu-kvm 6178 root 15 -5 1495476 48092 10676 S 28.1 0.0 300:58.82 supervdsmServer 361 root 25 5 0 0 0 S 7.0 0.0 333:14.58 ksmd 265 root rt 0 0 0 0 S 2.6 0.0 0:06.80 migration/32 27504 qemu 20 0 5137240 4.412g 13516 S 2.6 3.5 10:53.39 qemu-kvm 30222 root 20 0 0 0 0 S 2.0 0.0 0:11.98 vhost-30219 6329 vdsm 0 -20 3258204 151772 13004 S 0.7 0.1 65:29.75 vdsm - Please tell me what should I do to improve the video performance.

Unable to connect to console in user portal
by Shalabh Goel 05 Jan '17

05 Jan '17

Hi, I have created two VMs on a node. Then I created a user and gave permission to the user for both as UserRole from the web console. Now when I login as the user to the user portal, I can see both the VMs. But when I click connect or double-click on a particular VM, I get an error message "Error while executing action VmLogon: Internal Engine Error". The ovirt engine and node version is 4.0. Please help Thank You Shalabh Goel

New User Portal - gathering feedback
by Marek Libra 05 Jan '17

05 Jan '17

Hi, with ovirt-4.1.0_beta2, new Basic User Portal is introduced, so far as tech preview. To try, please follow the new "Basic User Portal" link from the main page. Recently most of previous (GWT based) Basic User Portal's functionality is available. In plan is full conformity and selected features of recent Extended Portal. Following goals were stated for this project: - improve UX by - modern UI (conforms Patternfly 3) - faster UI responses - shareable - built from reusable components to share portions of the UI in other projects (like ManageIQ) - POC for ongoing oVirt UI development - one of the options for next-gen oVirt UI to consider >From technical perspective, the project is based on - oVirt REST API - React/Redux/Saga - Patternfly 3 - pure JavaScript App without server-side processing except the existing REST API So far, the project is tech preview to gather user feedback. Please share your comments and ideas, it will really help with ongoing development. Real-life use-cases (both existing or potential) will be much appreciated. Thanks, Marek
