GSoC 2017 - my name is Marcin
by Marcin Czarnecki 15 Feb '17

15 Feb '17

Hello all, I am studying Computer Science at the University of Brighton (UK). I am interested in participating in Google Summer of Code 2017 with oVirt. I am a web security and anonymity enthusiast, tried to work with the Tor Project for GSoC 2016 but it did not work out. I have gained a lot of related experience during university, internship and my freelancing work, I could use this experience in your suggested projects: * VMs: I have experience with vSphere and deploying VMs of test clients in the company that I am doing my internship for * Ansible: I have created multiple playbooks for installing monitoring on test clients: Nagios, Graylog etc. (both on Windows, Linux [Ubuntu, RHEL] * my main interest is back-end web development, have been doing that for 3 years professionally, as well as projects on my own. Can provide with portfolio and customers' reviews * I also have some experience with automation in general: testing, installation of services etc. I think that with those skills I could try working on below two projects from the proposed list: * "Host reservation system for testing multiple oVirt instances" * "Ansible playbooks for oVirt deployment with remote resources" I have experience with Linux, have been using Ubuntu for 4 years on my PC and at work and in projects, and prefer it for development and server management. If you have any questions: email: marnczarnecki[at]gmail.com IRC (OFTC): marncz Many thanks, Marcin

gdeploy error
by Ishmael Tsoaela 15 Feb '17

15 Feb '17

Hi, I am a new sys admin and trying to install glusterfs using gdeploy, I started with a simple script to enable a service(ntpd). gdeploy --version gdeploy 2.0.1 [root@ovirt1 gdeploy]# cat ntp.conf [hosts] ovirt1 [service1] action=enable service=ntpd [service2] action=start service=ntpd The issue is that the gdeploy is returning error fatal: [ovirt1]: FAILED! => {"failed": true, "msg": "module (setup) is missing interpreter line"} Is there a simple way to debug or figure out how to fix this error?

Two Problems On New Install
by Charles Tassell 14 Feb '17

14 Feb '17

Hi Everyone, I recently installed oVirt 4.0 on two servers with an iSCSI backstore, and I'm having two issues I'm having trouble tracking down. First, the initial datastore that the hosted engine is running on won't connect. It just says "Unattached" in the GUI, and I can't find an error message anywhere. Not a huge deal, it just means I can't see the hosted engine itself in the GUI. More importantly: I can't migrate VMs. They fail with errors like this in the vdsm.log of the destination host: Thread-60381::ERROR::2017-02-14 21:55:47,921::vm::767::virt.vm::(_startUnderlyingVm) vmId=`59f235cc-3ab2-4dae-b460-62be850e3d5d`::Failed to start a migration destination vm Traceback (most recent call last): File "/usr/share/vdsm/virt/vm.py", line 733, in _startUnderlyingVm self._completeIncomingMigration() File "/usr/share/vdsm/virt/vm.py", line 3113, in _completeIncomingMigration self._incomingMigrationFinished.isSet(), usedTimeout) File "/usr/share/vdsm/virt/vm.py", line 3196, in _attachLibvirtDomainAfterMigration raise MigrationError(e.get_error_message()) MigrationError: Domain not found: no domain with matching uuid '59f235cc-3ab2-4dae-b460-62be850e3d5d' If I shut the VM down and start it on the host it works fine, it just won't migrate. I notice I'm also seeing a lot (like every 7 seconds) of this error: JsonRpc (StompReactor)::ERROR::2017-02-14 21:57:33,984::betterAsyncore::113::vds.dispatcher::(recv) SSL error during reading data: unexpected eof Which I can't seem to diagnose. Any ideas?

high number of IOPS from ovirt hosts
by Andrea Fagiani 14 Feb '17

14 Feb '17

Hi, We've got a 8-host cluster running oVirt 4.1; each host is connected via iscsi to a EQL 4100 storage (2x). Most of the VMs use barely any IOPS, however on our storage controller we've noticed a constant steam of reads, about 2000 IOPS; any idea what might cause the ovirt hosts to hammer on the storage so much? Looking at iotop, it seems that systemd-udevd is being activated every few seconds (and its IO% is usually fairly high) so I assume this might be somehow related. Thanks, Andrea

questions about migrating to self-hosted engine from bare-metal
by cmc 14 Feb '17

14 Feb '17

Hi, I want to migrate from a bare-metal engine to a self-hosted one. I'm following the guide at: http://www.ovirt.org/documentation/self-hosted/chap-Migrating_from_Bare_Met… I've created a new VM with el 7.3 on the existing cluster, and used an NFS share as storage on another VM, (which does not fill up). It gets most of the way through and then mentions failing to execute 'closing_ip', and fails to start the VM: [ INFO ] Creating Image for 'hosted-engine.lockspace' ... [ INFO ] Image for 'hosted-engine.lockspace' created successfully [ INFO ] Creating Image for 'hosted-engine.metadata' ... [ INFO ] Image for 'hosted-engine.metadata' created successfully [ INFO ] Creating VM Image [ INFO ] Extracting disk image from OVF archive (could take a few minutes depending on archive size) [ INFO ] Validating pre-allocated volume size [ INFO ] Uploading volume to data domain (could take a few minutes depending on archive size) [ INFO ] Image successfully imported from OVF [ INFO ] Destroying Storage Pool [ INFO ] Start monitoring domain [ INFO ] Configuring VM [ INFO ] Updating hosted-engine configuration [ INFO ] Stage: Transaction commit [ INFO ] Stage: Closing up The following network ports should be opened: tcp:5900 tcp:5901 tcp:9090 udp:5900 udp:5901 An example of the required configuration for iptables can be found at: /etc/ovirt-hosted-engine/iptables.example In order to configure firewalld, copy the files from /etc/ovirt-hosted-engine/firewalld to /etc/firewalld/services and execute the following commands: firewall-cmd -service hosted-cockpit firewall-cmd -service hosted-console [ INFO ] Creating VM [ ERROR ] Failed to execute stage 'Closing up': The VM is not powering up: please check VDSM logs [ INFO ] Stage: Clean up [ INFO ] Generating answer file '/var/lib/ovirt-hosted-engine-setup/answers/answers-20170213142939.conf' [ INFO ] Stage: Pre-termination [ INFO ] Stage: Termination [ ERROR ] Hosted Engine deployment failed: this system is not reliable, please check the issue,fix and redeploy Log file is located at /var/log/ovirt-hosted-engine-setup/ovirt-hosted-engine-setup-20170213141937-0wgc31.log In the vdsm log, it appears to be complaining about the volume not existing, but I can see it (it is on NFS) I've attached the vdsm.log and answers.conf Any help appreciated. Thanks, Cam

Bandiwdth limit on a Virtual Machine
by Fernando Frediani 13 Feb '17

13 Feb '17

Hello. Is there any limitation of bandwidth for a Virtual Machine per default ? I have a host with a bonding of 3 x 1Gb and the VM is connected to that bonding. On the Engine interface on the VM status I see "Network" and it has a percentage and a tiny graph. What that percentage is related to ? 1Gb ? 3Gb ? 10Gb ? Is there anything that has to be done in order the VM can achieve speeds over 1Gbps ? Fernando
