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

OVA export/import
by RabidCicada 14 Jun '18

14 Jun '18

All, I recently tried to used the OVA export/import functionality. It seems I misunderstood the intentions. I expected OVA export/import to be reciprocal functionalities. I expected what we export as OVA to be importable as OVA in ovirt. What I have found is the following: * It seems OVA export does export an OVA, though the format is not spec compliant * We use 'disk/' in the HostResource xml field instead of '/disk/' for example in the ovf. * It seems OVA import is intended specifically for VMWare OVA's? * I thought I read about export domains being deprecated, and incorrectly assumed the recently added OVA export/import was to make things better for one off import/export. Can anyone clarify the following: * Is OVA import really just VMWare OVA's? * Are we really not spec compliant with the OVA/OVF format as my example above shows? OR do I misunderstand something? * After spending my time yesterday, I recall now that the deprecation of export domain is in favor of detaching and re-attaching ANY data domain. * What is the purpose of our OVA export if we ourselves indeed cannot import our own OVA? Or can you tell me how we import our own if I'm wrong. Please feel free to overshare details :), as any context will help prevent more confusion on my part. ~Kyle

Ovirt-Hosted-Engine-Install-Purge Ansible Script Snippet
by RabidCicada 14 Jun '18

14 Jun '18

All, I put together a full purge ansible script for CentOS. I figured I'd share it here. I ran into many issues with spurious failures of installs when I would try to reinstall ovirt on CentOS after having "removed" it. I was developing an automated install of our own software along with ovirt but along the way I had to reinstall on the same box numerous times. Initially I'd get spurious failures from leftover cruft that would get in the way. I eventually found this:https://www.ovirt.org/documentation/how-to/hosted-engine/#recoving-fro… and then crafted my own ansible purge script. It uses ovirts own engine cleanup script first if it exists, then fully cleans every other thing that can affect it. Tested on CentOS, probably will work on other distros without too much trouble. Hopefully someone saves themselves some grief - name: Clean Old Install #This attempts to remove all old cruft from previous install attempts #The reason we include the ovirt packages is so that they can be reinstall #At potentially newer versions along with dependency packages block: - name: Detect existing cleanup script shell: which ovirt-hosted-engine-cleanup | cat register: ohes_cleanup - name: Debug ohes_cleanup.stdout debug: var: ohes_cleanup.stdout - name: Run Ovirt's Hosted Engine Cleanup Script shell: ovirt-hosted-engine-cleanup -q when: ohes_cleanup.stdout != "" - name: Clean old packages package: name: "{{item}}" state: absent with_items: - "*vdsm*" - "*ovirt*" - "*libvirt*" - "*cockpit*" - name: Remove old configs etc shell: "rm -rf /etc/{{item}}" args: warn: False with_items: - "/etc/*ovirt*" - "/etc/*vdsm*" - "/etc/libvirt/qemu/HostedEngine*" - "/etc/*libvirt*" - "/etc/guacamole" - "/etc/pki/vdsm" - "/etc/pki/libvirt" - "/etc/pki/CA" - "/etc/pki/keystore" - "/etc/ovirt-hosted-engine" - "/var/lib/libvirt/" - "/var/lib/vdsm/" - "/var/lib/ovirt-hosted-engine-*" - "/var/log/ovirt-hosted-engine-setup/" - "/var/cache/libvirt/" - "/etc/libvirt/nwfilter/vdsm-no-mac-spoofing.xml" - "/var/cache/tomcat/temp/*" - "/var/cache/tomcat/work/Catalina/localhost/*" - "/usr/share/tomcat/webapps/guacamole" - "/usr/share/tomcat/webapps/guacamole.war" - "/etc/guacamole/extensions/guacamole*" - name: Clean old repo files shell: "rm -rf /etc/yum.repos.d/{{item}}" args: warn: False with_items: - "ovirt*" - "virt*" - name: clean interface configs shell: "rm -rf /etc/sysconfig/network-scripts/ifcfg-ovirtmgmt" args: warn: False - name: clean network stuff shell: "{{item}}" args: warn: False with_items: - "brctl delbr ovirtmgmt | cat" - "ip link del ovirtmgmt | cat" - "ip link del dummy0 | cat" - "ip link del virbr0 | cat" - "ip link del virbr0-nic | cat" - 'ip link del \;vdsmdummy\; | cat'
