ovirt 4.2.5.2-1.el7 cannot locate ovirt-host package when trying to add new host
by Douglas Duckworth 21 Aug '18

21 Aug '18

Hi Do we need to add the ovirt repo on new potential host? If I don't do that manually then adding host, via oVirt UI, fails. The error: 2018-08-21 17:08:49,957-0400 DEBUG otopi.context context._executeMethod:143 method exception Traceback (most recent call last): File "/tmp/ovirt-w7xzFVIWO7/pythonlib/otopi/context.py", line 133, in _executeMethod method['method']() File "/tmp/ovirt-w7xzFVIWO7/otopi-plugins/ovirt-host-deploy/host/packages.py", line 69, in _validation 'Cannot locate ovirt-host package, ' RuntimeError: Cannot locate ovirt-host package, possible cause is incorrect channels 2018-08-21 17:08:49,958-0400 ERROR otopi.context context._executeMethod:152 Failed to execute stage 'Setup validation': Cannot locate ovirt-host package, possible cause is incorrect channels 2018-08-21 17:08:49,958-0400 DEBUG otopi.plugins.otopi.dialog.machine dialog.__logString:204 DIALOG:SEND **%EventEnd STAGE validation METHOD otopi.plugins.ovirt_host_deploy.host.packages.Plugin._validation (None) 2018-08-21 17:08:49,958-0400 DEBUG otopi.context context.dumpEnvironment:859 ENVIRONMENT DUMP - BEGIN 2018-08-21 17:08:49,958-0400 DEBUG otopi.context context.dumpEnvironment:869 ENV BASE/error=bool:'True' 2018-08-21 17:08:49,958-0400 DEBUG otopi.context context.dumpEnvironment:869 ENV BASE/exceptionInfo=list:'[(<type 'exceptions.RuntimeError'>, RuntimeError('Cannot locate ovirt-host package, possible cause is incorrect channels',), <traceback object at 0x7f7b46d58cb0>)] Though if I add https://resources.ovirt.org/pub/yum-repo/ovirt-release42.rpm on the new host manually then adding the new host succeeds.

vdsm hook
by 董青龙 21 Aug '18

21 Aug '18

Hi all, I want to write a hook in which name or id of the vm can be acquired and the hook should be executed before the vm shutdown. I could acquire name or id of the vm in a before_vm_start hook using "hooking.read_domxml()". However, it did not work in a before_vm_destroy hook. So what should I do? Can Anyone give me some advice? Thanks a lot!

how to reset engine-config parameter?
by Gianluca Cecchi 21 Aug '18

21 Aug '18

Hello, I tried to setup UserDefinedVMProperties to disable macspoofing for a vm that has to work as hypervisor. Then I remembered suggestion of Simone about creating vnic profile as an alternate method and set there the filter. I think I have done something wrong because if I create now a new vm and try to power on it I get VM test is down with error. Exit message: Hook Error: ('',). Perhaps I failed the syntax to reset the value of UserDefinedVMProperties ? I used [root@ovirt ~]# engine-config -s "UserDefinedVMProperties=" Please select a version: 1. 4.1 2. 3.6 3. 4.0 4. 4.2 4 [root@ovirt ~]# engine-config -g UserDefinedVMProperties UserDefinedVMProperties: version: 4.1 UserDefinedVMProperties: version: 3.6 UserDefinedVMProperties: version: 4.0 UserDefinedVMProperties: version: 4.2 [root@ovirt ~]# systemctl restart ovirt-engine [root@ovirt ~]# What could be wrong? Old created VMs start without problem. In the middle I updated the engine from 4.2.5.2 to 4.2.5.3 and also hypervisor packages, where vdsm has remained at level Aug 03 23:55:09 Updated: vdsm-4.20.35-1.el7.x86_64 In particular: [root@ovirt01 ~]# rpm -qa|grep vdsm vdsm-jsonrpc-4.20.35-1.el7.noarch vdsm-common-4.20.35-1.el7.noarch vdsm-hook-nestedvt-4.20.35-1.el7.noarch vdsm-yajsonrpc-4.20.35-1.el7.noarch vdsm-hook-ethtool-options-4.20.35-1.el7.noarch vdsm-hook-vhostmd-4.20.35-1.el7.noarch vdsm-hook-vmfex-dev-4.20.35-1.el7.noarch vdsm-client-4.20.35-1.el7.noarch vdsm-4.20.35-1.el7.x86_64 vdsm-hook-vfio-mdev-4.20.35-1.el7.noarch vdsm-api-4.20.35-1.el7.noarch vdsm-hook-fcoe-4.20.35-1.el7.noarch vdsm-network-4.20.35-1.el7.x86_64 vdsm-hook-openstacknet-4.20.35-1.el7.noarch vdsm-python-4.20.35-1.el7.noarch vdsm-http-4.20.35-1.el7.noarch [root@ovirt01 ~]# The error on hypervisor: 2018-08-21 15:21:28,760+0200 ERROR (vm/eaaee084) [virt.vm] (vmId='eaaee084-1949-4aae-85c2-6bf46fce7cef') The vm start process failed (vm:94 2) Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/virt/vm.py", line 871, in _startUnderlyingVm self._run() File "/usr/lib/python2.7/site-packages/vdsm/virt/vm.py", line 2864, in _run self._buildDomainXML(), File "/usr/lib/python2.7/site-packages/vdsm/virt/vm.py", line 2253, in _buildDomainXML dom, self.id, self._custom['custom']) File "/usr/lib/python2.7/site-packages/vdsm/virt/domxml_preprocess.py", line 240, in replace_device_xml_with_hooks_xml dev_custom) File "/usr/lib/python2.7/site-packages/vdsm/common/hooks.py", line 136, in before_device_create params=customProperties) File "/usr/lib/python2.7/site-packages/vdsm/common/hooks.py", line 122, in _runHooksDir raise exception.HookError(err) HookError: Hook Error: ('',) 2018-08-21 15:21:28,760+0200 INFO (vm/eaaee084) [virt.vm] (vmId='eaaee084-1949-4aae-85c2-6bf46fce7cef') Changed state to Down: Hook Error: ('',) (code=1) (vm:1682) I found this, but it doesn't seem related: https://bugzilla.redhat.com/show_bug.cgi?id=1518703 Thanks in advance for any hint, Gianluca

Hi I keep getting this error after running sudo hosted-engine --deploy --noansible [ INFO ] Engine is still not reachable, waiting... [ ERROR ] Failed to execute stage 'Closing up': Engine is still not reachable I do see a VM running 10:20 2:51 /usr/libexec/qemu-kvm -name guest=HostedEngine,debug-threads=on Though sudo hosted-engine --vm-status [Errno 2] No such file or directory Cannot connect to the HA daemon, please check the logs An error occured while retrieving vm status, please make sure the HA daemon is ready and reachable.

Hosted Engine setup issues
by Jeremy Tourville 21 Aug '18

21 Aug '18

If I try to setup hosted engine with the option to use Ansible it eventually fails on me. See https://lists.ovirt.org/archives/list/users@ovirt.org/thread/LPK7OGFALSQFAN… However if I run hosted-engine --deploy --noansible the setup does complete. There is further trouble though, it seems the networks are not being configured properly. If I browse to Compute>Hosts>Hostname and click on the Setup Host Networks button I am presented with a new window that contains an unassigned logical network of "oivrtmgmt" On the left side pane there are two columns for Interfaces and Assigned Logical Networks. Both of those columns are completely empty. I think if I understand correctly the interfaces column should at least have some info in it. [cid:bb1f29b4-888c-410a-9b47-7589f866539a] So my best guess is that for some unknown reason (at least to me) the Engine doesn't '"know how to get setup properly" either with or without Ansible. That's about as well as I can describe it. I hope it makes sense.... Anyone have ideas on what is going wrong here? Thanksfor any troubleshooting advice you can provide!

IPTables firewall to firewalld
by p.staniforth＠leedsbeckett.ac.uk 21 Aug '18

21 Aug '18

Hello, I get the following messages. "Cluster Default uses IPTables firewall, which has been deprecated in 4.2 of the engine, and will no longer be supported starting with version 4.3. Make sure to switch to Firewalld before upgrading to 4.3." If the correct way to change to firewalld edit cluster, and run reinstall? Thanks, Paul S.

Failed to run check-update of host

I have a fairly recent three node HCI setup running 4.2.5. I've recently updated hosted engine to the latest version (including yum updates).
