RHEL 7.5 as an oVirt host - missing packages
by jasonmicron＠gmail.com 19 Jun '18

19 Jun '18

Hello everyone, I believe there is a potential issue with the RHEL 7 yum repos and at least one missing RPM to convert a pre-existing RHEL 7.5 system into an oVirt host node. I have the following YUM repos enabled in my RHEL 7 system, according to the documentation: rhel-7-server-rpms rhel-7-server-optional-rpms rhel-7-server-extras-rpms I installed the oVirt 4.2 RPM: ovirt-release42-4.2.3.1-1.el7.noarch I then go to the engine GUI to add the new host, and during the installation process I am informed that there is a YUM transaction error with the following package being unavailable: python-qpid-proton (as a dependency install for the python-gofer-proton package) I dug around Red Hat's YUM repos and discovered that this package only exists in the rhel-7-server-satellite-tools-6.{1..3}-rpms YUM repos from the official Red Hat site. I tried enabling this repo (specifically the rhel-7-server-satellite-tools-6.3-rpms repo) to see which version of the package would be installed, and it appears to be a custom spin for Satellite in the release version: ============================================================================================================= Package Arch Version Repository Size ============================================================================================================= Installing: python-gofer-proton noarch 2.7.7-3.el7sat lab1-rhel-7-server-satellite-tools-6.3-rpms 54 k Installing for dependencies: python-gofer noarch 2.7.7-3.el7sat lab1-rhel-7-server-satellite-tools-6.3-rpms 132 k python-qpid-proton x86_64 0.16.0-7.el7 lab1-rhel-7-server-satellite-tools-6.3-rpms 216 k qpid-proton-c x86_64 0.16.0-7.el7 lab1-rhel-7-server-satellite-tools-6.3-rpms 131 k Transaction Summary ============================================================================================================== Install 1 Package (+3 Dependent packages) Since I shouldn't even require this repo according to the official oVirt install documentation for hosts, and the fact that these packages appear to be custom spins (el7sat) versions, I was curious if this is OK to use for oVirt or if I have encountered a dependency bug with RHEL 7.5 and oVirt 4.2? Any advice would be welcomed.

oVirt 4.2 vm-portal console
by Staniforth, Paul 19 Jun '18

19 Jun '18

Hello, I have installed a test system for oVirt 4.2 and it seems that in the vm portal I can't change the console to vnc or spice+vnc. It seems that this is only available in the admin portal. Am I missing something? Thanks, Paul S. To view the terms under which this email is distributed, please go to:- http://disclaimer.leedsbeckett.ac.uk/disclaimer/disclaimer.html

Ovirt Node NG (4.2.3.1-0.20180530) Boot fail ISCSI using ibft after installation
by Ralf Schenk 18 Jun '18

18 Jun '18

Hello, I successfully installed Ovirt Node NG from ISO to an ISCSI target attached via first network interface by using following extensions to the grub cmdline: "rd.iscsi.ibft=1 ip=ibft ip=eno2:dhcp" I want to use the server as diskless ovirt-node-ng Server. After successful install the system reboots and starts up but it fails later in dracut even having detected correctly the disk and all the LV's. I think "iscsistart" is run multiple times even after already being logged in to the ISCSI-Target and that fails finally like that: *[ 147.644872] localhost dracut-initqueue[1075]: iscsistart: initiator reported error (15 - session exists)* [ 147.645588] localhost dracut-initqueue[1075]: iscsistart: Logging into iqn.2018-01.de.databay.office:storage01.epycdphv02-disk1 172.16.1.3:3260,1 [ 147.651027] localhost dracut-initqueue[1075]: Warning: 'iscsistart -b ' failed with return code 0 [ 147.807510] localhost systemd[1]: Starting Login iSCSI Target...

HostedEngine and affinity groups
by tehnic＠take3.ro 18 Jun '18

18 Jun '18

Hi, i operate a 3 node ovirt42 cluster (hyperconverged). Now i would like to isolate the HostedEngine from the other VMs. The reason is to minimize the impact of outage of one of the nodes. When the node with the HE is away there is no impact at all on the running VMs. If one of the other nodes goes down, then i have still a running HE which restarts the missing VMs on remaining nodes fast again. I cannot use hard affinity because in case of failure i need all resources of the 2 remaining modes, so i configured a soft negative affinity group for every VM between this VM and the HE. As a first test i migrated the HE to a node with VMs but even after a while nothing happened. I would have expected that either the HE or the VMs on this node would have been migrated to fullfill the soft negative affinity. Now my questions: Are my thoughts correct? Is there a better solution than making one (soft negative) affinity group for every VM to isolate from HE? Does the affinity group enforcement engine work at all with soft rules? Regards, Robert

VM can't start: Unknown CPU-Model
by Tobias Scheinert 18 Jun '18

18 Jun '18

Hi, we see here a confusing problem. A college reboots/shutdown his VMs for maintenance. After that he starts the VMs (~20), but one of them throws following error: > VM <name> is down with error. Exit message: internal error: Unknown CPU-Model SandyBridge,+spec-ctrl All nodes of the clusters are reporting: > CPU Type: > Intel SandyBridge IBRS Family And the cluster is configured with: > Cluster CPU Type: > Intel SandyBridge IBRS Family My quick fix for the vm was, that I used a specific (not the cluster default) CPU-Model without the spectre/meltdown mitigation: > Guest CPU Type: > SandyBridge I've also tried to select manually "SandyBridge,+spec-ctrl". But when I do this the wizard blocks and surround the field with a red border (see picture in the attachment). Any idea? Greeting Tobias

ovirt 4.2 and hugepages
by Gianluca Cecchi 18 Jun '18

18 Jun '18

A part from configuring high performance vm, that gives me no high availability. Can I allocate huge pages using vdsm-hook-hugepages-4.19.31-1.el7.centos.noarch it seems that after updating an environment to 4.2 I'm not able to start a VM configured with the custom property I get Th ehost xxxxx did not satisfy internal filter HugePages because there are not enough free huge pages to run the VM But on host I have # cat /proc/meminfo | grep -i huge AnonHugePages: 0 kB HugePages_Total: 60000 HugePages_Free: 60000 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 2048 kB # and the custom property is configured to allocate 8200 huge pages to the guest The gropu configured in sysctl.d/10-hugepages.conf is vm.hugetlb_shm_group = 36 Do I have to set anything in /etc/securily/limits.d/ for qemu user? Thanks In advance, Gainluca

Gluster not synicng changes between nodes for engine
by Hanson Turner 18 Jun '18

18 Jun '18

Hi Guys, I've got 60 some odd files for each of the nodes in the cluster, they don't seem to be syncing. Running a volume heal engine full, reports successful. Running volume heal engine info reports the same files, and doesn't seem to be syncing. Running a volume heal engine info split-brain, there's nothing listed in split-brain. Peers show as connected. Gluster volumes are started/up. Hosted-engine --vm-status reports : The hosted engine configuration has not been retrieved from shared storage. Please ensure that ovirt-ha-agent is running and the storage server is reachable. This is leaving the cluster in an engine down with all vm's down state... Thanks,

Install CiscoISE VM on oVirt
by Anantha Raghava 18 Jun '18

18 Jun '18

Hi, I am not sure whether I should write it here. However the documents referred to specifies that I have change something in BIOS of VM & there is no way to get access to BIOS. Hence I am writing here. I am trying to install Cisco ISE in a VM on oVirt. The installation process halts reporting "Unsupported Hardware Found. The Cisco UDI (Unique Device Identifier) found on this appliance does not match with supported UDI of the product being Installed. Exiting installation" However it works perfectly on VMWare ESXi, VMWare Workstation and VMWare Fusion. In fact I tested this in VMWare Workstation and VMWare Fusion. The same ISO file throws above error. Cisco ISE is based on RHEL 7 and it is hardened. Has any one attempted to install Cisco ISE in oVirt? Any one throw some light? My oVirt Version 4.2.3 and Hosts are on 4.1.9 Thanks & regards, Anantha Raghava
