metrics-store installation
by Christoph Köhler 23 Feb '20

23 Feb '20

Hello! I have installed metrics store along this documentation: https://ovirt.org/documentation/metrics-install-guide/Installing_Metrics_St… Everything went fine without errors, so I have now the login page in my browser. The Problem is that the credentials for login seems to be not taken over. The user should be 'admin' and the password is given at the beginning in secure_vars.yaml. Does anyone have an idea what to do now? Greetings! Chris

paused vm's will not resume
by eevans＠digitaldatatechs.com 23 Feb '20

23 Feb '20

I have 2 vm's, which are the most important in my world, that paused and will not resume. I have googled this to death but no solution. It stated a lack of space but none of the drives on my hosts are using more than 30% or there space and these 2 have ran on kvm host for several years and always had at least 50% free space. I like ovirt and want to use it but I cannot tolerate the down time. If I cannot get this resolved, I'm going back to kvm hosts. I am pulling my hair out here. If anyone can help with this issue, please let me know.

Hugepages and running out of memory
by klaasdemter＠gmail.com 22 Feb '20

22 Feb '20

Hi, this e-mail is meant to caution people using hugepages and mixing those VMs with non-hugepages VMs on the same hypervisors. I ran into major trouble, the hypervisors ran out of memory because the VM scheduling disregards the hugepages in it's calculations. So if you have hugepages and non-hugepages VMs better check the memory commited on a hypervisor manually :) https://bugzilla.redhat.com/show_bug.cgi?id=1804037 https://bugzilla.redhat.com/show_bug.cgi?id=1804046 As for workarounds: so far it seems the only viable solution is splitting hugepages/nonhugepages VMs with affinity groups but at least for me that means wasting a lot of resources. Greetings Klaas

Hi, Having a spice console issue on our new 4.3.8 cluster. The console stays blank and with the cli and debug on, I get the following error "main channel: failed to connect HTTP proxy connection not allowed" We have a userportal through haproxy so this is configured in ovirt engine engine-config -g SpiceProxyDefault SpiceProxyDefault: http://userportal.*.*:****/ version: general But the same setting works fine on our 4.2 cluster. I can telnet to the ports on the 4.3.8 hosts without issue.

Understanding dashboard memory data
by nux＠li.nux.ro 21 Feb '20

21 Feb '20

Hello, I'm having to deal with an oVirt installation, once I log in the dashboard says: Memory: "1.2 Available of 4.5 TiB" and "Virtual resources - Committed: 113%, Allocated: 114%". So, clearly there is RAM available, but what's with the committed and allocated numbers? Regards

Ovirt storage domain ovirt-image-repository is unattached and can't use change CD to install windows on VM
by Heinrich Momberg 20 Feb '20

20 Feb '20

Good day, Whenever i am trying to use the change CD to mount the ovirt tools iso so i can install windows server or any windows it says "could not find ISO file collection".It doesn't pick up the hdd that i have created in the windwos setup so i have to do the whole ovirt tools mount and select the windows i want to insteall etc. It has been working fine until a couple of days ago when we had power outages. I also noticed that the storage domain,ovirt-image-repository is unattached... How do i go about fixing this problem or where can i check logs. I have checked the permissions where the ISO's or images are stored.

Spacewalk Integration
by eevans＠digitaldatatechs.com 20 Feb '20

20 Feb '20

I finally figured out how to use Spacewalk as an external provider in Ovirt. For the URL I used http://sat.digitaldatatechs.com/XMLRPC and used the admin login credentials. It registered and Spacewalk has the capability of provisioning a bare bones machine. I have not tested provisioning but I will comment once I do.
