PythonSDK 4.2.8 issues updating cdrom iso of a vm.
by Brad Riemann 22 Oct '18

22 Oct '18

Hello, I am currently fighting with attaching an iso to a vm's cdrom. There are two isos in the iso domain (A-Iso-Installer.iso and The-Iso-Installer.iso for our purposes), I can confirm the iso domain is attached to the cluster and everything is green. When attempting to attach the iso to the vm, I can see the pre and post output of the "/ovirt-engine/api/vms/<uuid>/cdroms" request, it shows the file id changing according to what the iso domain has available. However, whenever i attempt to power on the vm, from either the api or through the web interface, I get "Invalid ISO image path". Editing the vm through the web interface reveals that the "Attach CD" dropdown has selected the first iso ("A-Iso-Installer.iso", and I am trying to use the second). I ran a list against the cdrom service, found no issues with the xml that was returned. I confirmed that listing out available isos on the iso domain results in the expected id that I matched in the cdrom service of the vm from the api. If I ch oose the correct iso from the gui and save, the output looks the same as the api listing. Before and After gist: https://gist.github.com/robotman321/909255cbdc36fa62b730a953807f7397 The code im using to set the cdrom is the following: https://gist.github.com/robotman321/35617c96b96b329d5d1476e015aa9898 I did note that when i would run the update api code, it does change SOMETHING as when i go into the web interface the "Attach CD" value has gone back to the top value in the dropdown (the wrong iso). Has anyone seen this before, please tell me it's right in front of me, any help is appreciated. Thank you, Brad

OVN Configuration
by Armond Kuehn 22 Oct '18

22 Oct '18

High I've been trying for a couple months to setup an Ovirt Cluster with OVN/OVS implemented. I can make a network work on my home single server deployment but any time I create a vm on my hyperconverged setup the VM crashes stating it can't connect to the br:ex. (error messages aren't included because lab has 0 external connectivity). I assume this is due to nothing creating the OVN/OVS connections on each host in the manner that my single server does. I know there are ways to manage this such as ManageIQ but I haven't had any luck finding a good guide or walkthrough to get my systems to integrate those products. Does anyone know of where I could find one? Or willing to walk a dummy through it? Armond

Wrong VLAN ID for Management Network
by Sakhi Hadebe 22 Oct '18

22 Oct '18

Hi, Can I just changed the VLAN ID of the ovirtmgmt network in the Admin Portal. IN the OS the network is configured and verified for ovirtmgmt network to have a 21 VLAN ID, but in the Admin Portal, it shows VLAN ID 20, which is configured for the VM network. Can I just changed it in the admin portal? Will the cluster be happy about the changes? -- Regards, Sakhi Hadebe

Problems with quotas
by siovelrm＠gmail.com 20 Oct '18

20 Oct '18

Hi, I need to use Ovirt's quotas system. I have approximately 50 users that use my Ovirt and they can create virtual machines only from templates, in total there are 20 templates. I have assigned a quota for each user, until here there are no problems. The problem is that in order for the user's quota to be used for each template, it must be linked to a specific quota, but only one. The only solution I see would be to have 20 templates for each user so it would be a total of 50X20 templates = 1000 templates and if a new user arrives 20 templates more and so on, which would not be a good solution. I think evidently or that I have not understood well how Ovirt's system of quotas works or maybe my problem can be solved in another way. Please I need your help

aquantia 107 (10Gbase-T NIC) driver for oVirt node-ng?
by Edward Berger 19 Oct '18

19 Oct '18

I'm not sure where to send a request for including the current Aquantia 107 (10GbaseT nic) driver to be included in the ovirt-node-ng image. I don't see a centos RPM for kmod-redhat-atlantic, apparently there's a scientific linux rpm available for download.
