I've created a VM using a template imported from a Fedora 24 image in the repository. Now that it is created, what credentials do I use to log into it from the console?

New installation
by david caughey 22 Jun '17

22 Jun '17

Hi Folks, I just got the go ahead to install oVirt to use as a lab. The servers are: 1xdl360 4x30010k in raid 10 for OS (Manager) should this be clustered with another server for resiliency 5xdl380 2x30010k for OS 6x1TB7.2k RAID5 on each for a data store It will all be behind a proxy and be connected with 1GB links, (2x4 bonds) My plan is to have 1 manager as this is a lab scenario and not production, (yet), or is it better to have a cluster. Is it ok to have a data store on each host, (they won't let me have dedicated storage yet)? Is it wise to share these data_stores between hosts or should 1 store be dedicated to each host individually? There is no need for performance, basically as long as it runs it will work. The final intention is to have templates for OpenStack and CEPH plus lots of Linux examples set up with SDN etc. We have a 90% Windows shop but it is all rapidly changing to OpenStack et al and I want to try and give people the opportunity to use Linux in the lab before they are let lose in production. Plus it gives me the chance to show management exactly what ovirt can do. Any help, advice or links would be greatly appreciated, BR/David

Lowering the bar for wiki contribution?
by Roy Golan 21 Jun '17

21 Jun '17

I'm getting the feeling I'm not alone in this, authoring and publishing a wiki page isn't as used to be for long time. I want to suggest a bit lighter workflow: 1. Everyone can merge their page - (it's a wiki) Same as with (public and open) code, no one has the motivation to publish a badly written wiki page under their name. True, it can have an impact, but not as with broken code 2. Use Page-Status marker The author first merges the draft. Its now out there and should be updated as time goes and its status is DRAFT. Maintainers will come later and after review would change the status to PUBLISH. That could be a header in on the page: --- page status: DRAFT/PUBLISH --- Simple I think, and should work.

Expand Hosted-Engine Disk Space
by Adam Chesterton 21 Jun '17

21 Jun '17

Hi All, I am encountering a situation where the hosted engine for my test setup has run out of space. It only has 10GB configured, which was an oversight on my part when first deploying it. All storage is Gluster replica 3 (4 volumes; engine, vm, iso, export) and I have plenty of available space. My oVirt version is currently at 4.1.1. I've spent time looking for a solution to expand the disk size, but without luck so far. Most items I've found from previous list emails are from the 3.5 days, and seem to indicate that by 3.6+ you should be able to modify the hosted engine from within the oVirt Admin Web Console. However, when I try to expand the hosted engine disk I get an error that the VM is not managed by the engine, so obviously that functionality is not yet implemented. So, my question is; what is the current process to expand the hosted engine disk? Regards, Adam Chesterton

GPFS Storage Domains - Live VM Migration Between LocalOnHost Only
by Douglas Duckworth 21 Jun '17

21 Jun '17

Hi I used RHEV in the past and now that I am in a new role we're considering oVirt. I have a few questions: Does oVirt support network Storage Domains using GPFS? Does oVirt support live VM Migration of between Hosts that have "LocalOnHost" (direct attached) Storage Domains only?

Error while installing oVirt Self Hosted Engine
by Jon Bornstein 21 Jun '17

21 Jun '17

This is roughly my 10th attempt at installing some version of oVirt and I think where I get stuck every time is with the networking aspect. I'm simply trying to test out oVirt on an old laptop wiht 16GB RAM and an external HDD. I'm connected via WiFi. After failing 100 times with the regular ovirt engine, It was recommended I try the self-hosted engine. ** Anyway, here are the contents of my /etc/hosts file: 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 10.114.13.144 host.example.rocks host 10.114.13.145 engine.example.rocks engine ** After running hosted-engine --deploy, I get to the prompt below in which the installer fails afterwards: You may specify a unicast MAC address for the VM or accept a randomly generated default [00:16:3e:5b:3a:73]: [ ERROR ] Failed to execute stage 'Environment customization': Cannot acquire nic/bridge address [ INFO ] Stage: Clean up [ INFO ] Generating answer file '/var/lib/ovirt-hosted-engine-setup/answers/answers-20170614163222.conf' [ INFO ] Stage: Pre-termination [ INFO ] Stage: Termination [ ERROR ] Hosted Engine deployment failed Log file is located at /var/log/ovirt-hosted-engine-setup/ovirt-hosted-engine-setup-20170614160653-2vuu7h.log ** Here is a tail of the log: [root@engine /]# tail /var/log/ovirt-hosted-engine-setup/ovirt-hosted-engine-setup-20170614160653-2vuu7h.log 2017-06-14 16:32:22 DEBUG otopi.context context._executeMethod:134 condition False 2017-06-14 16:32:22 INFO otopi.context context.runSequence:687 Stage: Termination 2017-06-14 16:32:22 DEBUG otopi.context context.runSequence:691 STAGE terminate 2017-06-14 16:32:22 DEBUG otopi.context context._executeMethod:128 Stage terminate METHOD otopi.plugins.gr_he_common.core.misc.Plugin._terminate 2017-06-14 16:32:22 ERROR otopi.plugins.gr_he_common.core.misc misc._terminate:178 Hosted Engine deployment failed 2017-06-14 16:32:22 DEBUG otopi.plugins.otopi.dialog.human dialog.__logString:204 DIALOG:SEND Log file is located at /var/log/ovirt-hosted-engine-setup/ovirt-hosted-engine-setup-20170614160653-2vuu7h.log 2017-06-14 16:32:22 DEBUG otopi.context context._executeMethod:128 Stage terminate METHOD otopi.plugins.otopi.dialog.human.Plugin._terminate 2017-06-14 16:32:22 DEBUG otopi.context context._executeMethod:128 Stage terminate METHOD otopi.plugins.otopi.dialog.machine.Plugin._terminate 2017-06-14 16:32:22 DEBUG otopi.context context._executeMethod:134 condition False 2017-06-14 16:32:22 DEBUG otopi.context context._executeMethod:128 Stage terminate METHOD otopi.plugins.otopi.core.log.Plugin._terminate ** This is my first time writing to this list, so hopefully I'm doing it right. Thanks in advance - this is driving me crazy!

Additional user in ovirt-node-ng 4.x
by Luca 'remix_tj' Lorenzetto 21 Jun '17

21 Jun '17

Hello, my colleague is asking if is possible to define a certain user on our hosts. I know that the rule is to avoid installations and changes to hosts running ovirt-node, but in this case the user creation should have a very minimum impact. He's running HP uCMDB that makes an ssh connection to the host for grabbing some system information to populate it's DB. Is possible to create a new user? Does this user is preserved with upgrades? Is possible also to allow this new user to run 4 (exactly 4) commands through sudo?

Change Hosted Engine Storage Connection
by Matt . 21 Jun '17

21 Jun '17

Hi All, What was the best way to change the storage connection for a hosted engine ? I moved the Engine at the moment to a new storage path and I thought I needed to extract the config package, change it and repackage it again. I thought this was not in the docs. Thanks! Matt
