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

Moving from thin to preallocated storage domains
by Albl, Oliver 17 Jun '18

17 Jun '18

Hi all, I have to move some FC storage domains from thin to preallocated. I would set the storage domain to maintenance, convert the LUN from thin to preallocated on the array, remove "Discard After Delete" from the advanced settings of the storage domain and active it again. Is there anything else I need to take care of? All the best, Oliver

Non-responsive vm's due to crashed host and hosted vm liveliness check fails
by clam2718＠gmail.com 15 Jun '18

15 Jun '18

Dear Community: The local drive on a host running ovirt-node-ng-4.1.9 in a three node cluster failed. I have production JIRA and Postres running on it at the time, not in HA, just simple vm's. Storage is via NFS on a Synology NAS. Hosted Engine was on a different host, but JIRA and Postgres vm's showed nonresponsive. I tried different things but then stupidly thought that upgrading my Hosted Engine would reinitialize the vm's that were on the failed host. Update of HE seemed to go well (output below) but now my Hosted Engine, while up, fails the liveliness check and the web management console is unavailable. I cannot console into the HE from the host it is running on. Below are the results of my attempts to console into the Hosted Engine. Please help! I have search forums, lists and Google but have not been able to fix this. My coworkers and manager are anxious. --- When I try "hosted-engine --console" after setting the console password I get The engine VM is running on this host Connected to domain HostedEngine Escape character is ^] _ The prompt is non-responsive except for the escape character key combo. --- "virsh -r list" gives ID 3, Name: HostedEngine, State: running "virsh -r console HostedEngine" gives Connected to domain HostedEngine Escape character is ^] error: operation forbidden: read only access prevents virDomainOpenConsole "virsh -r vncdisplay HostedEngine" gives "0:0" and returns me to prompt --- I am SSHed into the host running my Hosted Engine from a CentOS7 minimal install with packages xorg-x11-server-Xorg, xorg-x11-xauth and xorg-x11-apps installed. The result of "grep -i X11Forwarding /etc/ssh/sshd_config" shows it set to "Yes". I SSH into the host using "ssh -Y root(a)xxx.xxx.xxx.xxx" I am logged into the CentOS7 minimal install as root. I know root is poor practice but was trying to minimize anything that could be causing an issue. --- Below are the results of my attempt to update Hosted Engine (slightly redacted to remove personal info): --== CONFIGURATION PREVIEW ==-- Default SAN wipe after delete : False Firewall manager : firewalld Update Firewall : True Host FQDN : ovengineint.xdomainx.tld Upgrade packages : True Engine database secured connection : False Engine database user name : engine Engine database name : engine Engine database host : localhost Engine database port : 5432 Engine database host name validation : False Engine installation : True PKI organization : xdomainx.tld Set up ovirt-provider-ovn : True Configure WebSocket Proxy : True DWH installation : True DWH database secured connection : False DWH database host : localhost DWH database user name : ovirt_engine_history DWH database name : ovirt_engine_history DWH database port : 5432 DWH database host name validation : False Configure Image I/O Proxy : True Configure VMConsole Proxy : True --== SUMMARY ==-- [ INFO ] Restarting httpd Web access is enabled at: http://ovengineint.xdomainx.tld:80/ovirt-engine https://ovengineint.xdomainx.tld:443/ovirt-engine Internal CA XX:XX:XX:XX...

User agent for Ovirt 4.2
by Jim Kusznir 15 Jun '18

15 Jun '18

Hi: I haven't managed to find the new / current repo/source for the ovirt guest agent for the 4.2 upgrade. All my VMs now say that they need the agent. Googles keep referring me to old / broke / non-existent repos. Where do I find the 4.2 agent (or does the 4.2 agent even exist?) Thanks! --Jim
