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.

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

Hosted Engine stopped on Good Agent -> 4.1.1
by Matt . 21 Jun '17

21 Jun '17

Hi Guys, I have moved my environment from datacenter to datacenter and it seems that my agents are doing "strange" after it. The engine starts but stops after being initialized and the agent.log doesn't show any errors. This happens on 4.1.1 One of the hosts which is a HE host has been upgraded to 4.1.2 to see what happens there and when I want to start the hosted engine there I get: # hosted-engine --vm-start Unable to read vm.conf, please check ovirt-ha-agent logs The HE storage is mounted well on the 4.1.1 host which doesn't mount the other NFS storages, but the 4.1.2 host has all storages (NFS) mounted which is kinda strange if you ask me. Where should I start as this cluster has been moved earlier without any issue. Thanks, Matt

Hi all, Are there any windows server 2016 guest tools? At the site it doesn't list this OS and during installation from ISO that is included in ovirt-guest-tools-iso package i receive the error that the OS is not supported. If these tools are not installed and I install only virtio tools are there any performance implications for the VM? Thanx, Alex

This is a multipart message in MIME format. ------=_NextPart_000_0033_01D2E917.5A627FD0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Hi, I would like to automatically set the hostname of a VM to be the same as the ovirt machine name seen in the portal. This can be done by creating a template and activating cloud-init in the initial run tab. A new VM named "test" based in this template is created and the hostname is "test", works perfect! But when I create a pool (i.e. "testpool") based on this template I get machines with names "testpool-1", "testpool-2", etc. but the machine name is not present in the metadata and cannot be set as hostname. This is probably due to the fact that the machine names are auto generated by the oVirt Pool. Is this expected/desired behavior for cloud-init from pools? If so, what would be the best way to retrieve the machine name (as seen in the portal) and manually set it to be hostname via cloud-init (i.e. runcmd - hostnamectl set-hostname $(hostname)) Kind regards, Paul ------=_NextPart_000_0033_01D2E917.5A627FD0 Content-Type: text/html; charset="us-ascii" Content-Transfer-Encoding: quoted-printable <html xmlns:v=3D"urn:schemas-microsoft-com:vml" = xmlns:o=3D"urn:schemas-microsoft-com:office:office" = xmlns:w=3D"urn:schemas-microsoft-com:office:word" = xmlns:m=3D"http://schemas.microsoft.com/office/2004/12/omml" = xmlns=3D"http://www.w3.org/TR/REC-html40"><head><meta = http-equiv=3DContent-Type content=3D"text/html; = charset=3Dus-ascii"><meta name=3DGenerator content=3D"Microsoft Word 15 = (filtered medium)"><style></style></head><body lang=3DNL = link=3D"#0563C1" vlink=3D"#954F72"><div class=3DWordSection1><p = class=3DMsoNormal><span lang=3DEN-US = style=3D'color:#1F497D'>Hi,<o:p></o:p></span></p><p = class=3DMsoNormal><span lang=3DEN-US = style=3D'color:#1F497D'><o:p> </o:p></span></p><p = class=3DMsoNormal><span lang=3DEN-US style=3D'color:#1F497D'>I would = like to automatically set the hostname of a VM to be the same as the = ovirt machine name seen in the portal.<o:p></o:p></span></p><p = class=3DMsoNormal><span lang=3DEN-US style=3D'color:#1F497D'>This can be = done by creating a template and activating cloud-init in the initial run = tab. <o:p></o:p></span></p><p class=3DMsoNormal><span lang=3DEN-US = style=3D'color:#1F497D'>A new VM named “test” based in this = template is created and the hostname is “test”, works = perfect!<o:p></o:p></span></p><p class=3DMsoNormal><span lang=3DEN-US = style=3D'color:#1F497D'><o:p> </o:p></span></p><p = class=3DMsoNormal><span lang=3DEN-US style=3D'color:#1F497D'>But when I = create a pool (i.e. “testpool”) based on this template I get = machines with names “testpool-1”, “testpool-2”, = etc. but the machine name is not present in the metadata and cannot be = set as hostname.
