ISO Upload "Paused by System"
by Ron Baduach -X (rbaduach - SQLINK LTD＠Cisco) 10 Jul '19

10 Jul '19

Hi Guys, I tried to upload an ISO, and from "chrome" it's just "paused by system" from the beginning From "Firefox", it started to upload, but after 0.5 hour it becomes "paused by system" too. I suspect it's the certificate issue, but I installed the certificate. [I'm working with Windows 10] Can you please tell me it this is the issue ?and if yes, how can I solve the Cert issue ? I'm just stuck here, so thanks in advance !

Ovirt Hyperconverged Cluster

I am installing ovirt 4.2 on three nodes. I am using centos with ovirt cockpit. My /sdb is my boot disk and /sda is my local storage, When I started the setup with cockpit I selected the sda but the ansible script stay on sdb. I have fix all changing the playbook manually but in the execution the gdeploy tool stay blocked on TASK [Create Physical Volume] . I don't find any logs. How I can fix that?

Regarding VDSM_Hooks
by Vrgotic, Marko 10 Jul '19

10 Jul '19

Dear oVIrt, Happy to report I have deployed my first python vdsm_hook which removes A, AAAA, TXT records of VM each time after_vm_destroy event is triggered, and it works fine. This was required to be able to quickly redploy/rebuild VMs using same hostname. Issue I am observing/just discovered now is: Since live_migration of VM guest is considered a destruction from Host perspective, DNS records get deleted and VM lands on new host without being resolvable 😊 . I would like to introduce another python script for hook regarding migration events to get these entries back into DNS but for that I need there IPs. Question: * Where can I find/locate/read VMs IPs and Hostnames (is it dom_xml) to be able to incorporate them for DNS Update script? If its relevant for the question: we are currently running oVIrt 4.3.3 version Kindly awaiting your reply. Marko Vrgotic ActiveVideo

VM Portal please add search filter box and list view as in Administration portal
by Vrgotic, Marko 10 Jul '19

10 Jul '19

Dear oVirt, This email has bounced two times already, and I am not sure what is wrong. Hopefully you get it this time. Request is below. Sent from my iPhone Dear oVirt, Would it be possible to discuss/consider adding search/filter field for VM Portal, resembling one in Administration Portal? I have 60 users with over 500VMs and it would be really good to have this option. At this moment is virtually impossible to use the VMPortal due to poor view options. We are currently running oVirt 4.3.3. — — — Met vriendelijke groet / Kind regards, Marko Vrgotic Sr. System Engineer @ System Administration m.vrgotic(a)activevideo.com<mailto:m.vrgotic@activevideo.com>

Don't forget to run a ping with a size of 8500 and "do not fragment" flag. This will really prove that you are no longer using the small MTU anywhere on the path.

oVirt Enginge Version: 3.5.0.1-1.el6 (yes....I know it's old) VM is running Ubuntu 18.04 with ovirt agent installed. I'm attempting to get NIC information by running 'ethtool -i ens3' I get the following: root@myserver:~# ethtool -i ens3 driver: virtio_net version: 1.0.0 firmware-version: expansion-rom-version: bus-info: 0000:00:03.0 supports-statistics: no supports-test: no supports-eeprom-access: no supports-register-dump: no supports-priv-flags: no root@myserver:~# and when I run 'ethtool ens3' I get the following: root@myserver:~# ethtool ens3 Settings for ens3: Supported ports: [ ] Supported link modes: Not reported Supported pause frame use: No Supports auto-negotiation: No Supported FEC modes: Not reported Advertised link modes: Not reported Advertised pause frame use: No Advertised auto-negotiation: No Advertised FEC modes: Not reported Speed: Unknown! Duplex: Unknown! (255) Port: Other PHYAD: 0 Transceiver: internal Auto-negotiation: off Link detected: yes This is not what I expected. Is there another tool I should be using to display the information for ens3 on this server?
