Trouble to update the ovirt hosts (and solution)
by Arman Khalatyan 02 Oct '18

02 Oct '18

Current cocpit packages are conflicting, which is preventing the host update: .... Transaction check error: file /usr/share/cockpit/networkmanager/manifest.json from install of cockpit-system-176-2.el7.centos.noarch conflicts with file from package cockpit-networkmanager-172-1.el7.noarch file /usr/share/cockpit/networkmanager/po.ca.js.gz from install of cockpit-system-176-2.el7.centos.noarch conflicts with file from package cockpit-networkmanager-172-1.el7.noarch .... Looks like a current packaging of cocpit is wrong, it doesn't upgrade existing version. To solve it simply: yum remove cockpit-networkmanager-172-1.el7.noarch yum clean ;yum update all fixed. arman.

clarification needed on power management options
by g.vasilopoulos＠uoc.gr 01 Oct '18

I would like some clarification on MinFreeMemoryForUnderUtilized and MaxFreeMemoryForOverUtilized. How does that work? it seems the names should be oposite ? so if I have hosts with 64GB ram and I want to consider them over utilized at 48GB used and under utilized at 12GB used, should I set MinFreeMemoryForUnderUtilized=12GB MaxFreeMemoryForOverUtilized=48GB ? is this correct ? Also If ihave hyperconverged setup with 3 hosts having a replica3 storage for the engine and I disable policy management on these hosts, will these hosts be part of the overall utilization regardless if the engine can shut them down ?

liveliness check fails on one host
by g.vasilopoulos＠uoc.gr 01 Oct '18

01 Oct '18

I have an ovirt installation (4.2.6), and I have come accross this issue: Hosted engine can migrate to a certain host say host5. Admin portal is working fine, everything is working fine AFAIK but hosted-engne --vm-status shows "failed livelines check", when engine is on that host, so after a while the engine migrates somewhere else, it not a terrible problem, but it is annoying and I would like to know why is this happening, and if there is a way to fix it On every other host in the cluster this problem does not exists. firewall rules are exactly the same on hosts (in fact they are copied) . Any places to look at? Thank you

I have at a cluster the following error, and this seems to have risen following a routine update (software packages) of the servers. When trying to delete a snapshot of a VM I get at GUI: General command validation failure. Engine logs the attached. Any help is appreciated. Thanx, Alex

Suggestion: Addition of a one-off PXE boot option in the "Edit Virtual Machine > Boot Options" section
by Zach Dzielinski 30 Sep '18

30 Sep '18

My current usage of oVirt requires me to switch the boot priorities for virtual machines from hard disk to pxe fairly often. It would be nice to see an option added in that would set a one-off pxe boot for virtual machines, reverting back to the original boot priorities after restart. This would save some time when dealing with multiple machines, by eliminating the need to switch them to pxe and then back to their previous boot options in the middle of their boot process.

Networking in oVirt
by sinan＠turka.nl 30 Sep '18

Hi all, Today I have installed oVirt 4.2 on a single machine (self hosted engine). My server has 6 physical adapters, but only 1 has an active uplink (enp2s0f0). The server is directly connected to the internet. The installation of oVirt created the following interfaces: - br-int - ovirtmgmt [IP configured: inet 85.17.x.x] - virbr0 [IP configured: inet 192.168.122.1] - virbr0-nic - vnet0 The hosted-engine is attached to ovirtmgmt and got IP 192.168.122.76 assigned. The hosted-engine does have access to the internet. The logical network ovirtmgmt is assigned to the physical interface enp2s0f0 when I check this via the oVirt webgui. I have 2 questions. Q1: I would like to achieve the following: - Create a new network, call it vm_network. - Create VM's and attach them to the vm_network. - These VM's should able to access the internet. Is this possible, if so, how do I achieve this? Q2: When my first question is answered and I have VM's running, some of the VM's I would like to give an external/public IP address. How do I achieve this? Thanks! Sinan
