Testing ansible playbook against a mock engine?
by Luca 'remix_tj' Lorenzetto 25 Oct '17

25 Oct '17

Hello, i'm planning to create a big standardization playbook for my environment to ensure that all the required configs (networks, hosts, host's nics and networks....) are correctly set up. Since i don't want to test against a running setup, i'd like to spawn a transient one for testing. I already know Lago, but i think is bit overkill for testing an ansible playbook. Is there any tool that creates only an engine instance with some fake hosts configured so i can test the playbook against it?

Re: [ovirt-users] move disk and lv not removed
by Idan Shaby 25 Oct '17

25 Oct '17

Hi Gianluca, Can you try to reproduce it with FC? Maybe it's somehow related to that. Did you try to lvremove the old lv's, or are they still in use? Trying to do this from the SPM should be ok. What do you mean synchronize the information at the other node side? In any case, this is a disk that you don't need anymore, isn't it? You said that the copy part of the move operation went well.

Troubles uploading iso files via engine-iso-uploader
by Edward Clay 24 Oct '17

24 Oct '17

Hello, I've recently ran into a problem after removing an old nfs mounted ISO domain and recreating it using glusterfs. When I attempt to upload an iso using engine-iso-uploader it shows that it's attempting to access the storage domain via nfs. ---snipet---- DEBUG: /bin/mount -t nfs -o rw,sync,soft 10.4.16.11:/ISOSB /tmp/tmpr4lwKy ------------- from the engine server I am able to mount the gluster volume from the above path without issues. Iguess I'm confused as to why it's attempting to connecting using nfs when I created the storage domain for it using glusterfs. I have 1 ovirt engine server with 7 host/hypervisors and a 3 node replicated gluster volume. I've created seperate storage domains for VM images(data) and for ISO images. Both storage domains are accessible from the engine server and all host. Meaning I'm able to mount the glusterfs volume from all 8 servers. -- Edward Clay Systems Adminstrator UK2 Group -- US Operations Phone: 1-800-222-2165 E-Mail: edward.clay(a)uk2group.com

unlock_entity.sh
by Johan Vermeulen 24 Oct '17

24 Oct '17

Hello All, first of all, I hope this question is not too trivial or hasn't been asked lately ( but i scrolled down the mailing list and didn't find anything similar, so...) I have a lot of trouble with locked disks when trying to remove vm's. I know there's the unlock_entity script but cannot get it to work. Where can I find a copy-paste-able uuid nr of the disk? It prompts me for a database password. Is this something I should have created when setting up Ovirt? Can anyone give me an example of a complete unlock entity command? Many thanks for any help. greetings, J.

Resize disk of powered on VM
by Gianluca Cecchi 24 Oct '17

24 Oct '17

Hello, I'm in 4.1.6. I have a VM with 2 virtio-scsi disks (on FC). If I try to do a resize of the boot disk (preallocated) from this menu: 1) - select VM - disks sub tab - select disk - edit - edit virtual disk window - extend size by X Gb I get error about "not all VMs are powered down" Instead if I do a resize of the same disk from this menu: 2) - select VM - edit VM - find the line of the disk and select the "edit" button at the right - edit virtual disk window - extend size by X Gb it works as expected, so without downtime Is this expected? Actually after 2) scenario, I had retried 1) and it works too this time. During the first 1) that failed, I see this in engine.log: Validation of action 'UpdateVmDisk' failed for user admin@internal-authz. Reasons: VAR__AC TION__UPDATE,VAR__TYPE__DISK,ACTION_TYPE_FAILED_VM_IS_NOT_DOWN But the VM is indeed up on all 3 attempts.... so I don't understand this message On another VM, again with a disk configured as virtio-scsi, but configured as thin provisioned, both from 1) and 2) scenario I get: c7service: - Cannot edit Virtual Disk. Cannot edit Virtual Disk. Disk extension combined with disk compat version update isn't supported. Please perform the updates separately. What does it mean "perform the updates separately"? I cannot online resize thin provisioned disks? The VM has only one disk, BTW. Thanks, Gianluca

Vnc client from windows 10
by Gianluca Cecchi 23 Oct '17

23 Oct '17

Hello, I'm trying to have a user connect to the console VM through vnc protocol, but without the virt-viewer application. The client is Windows 10. I have tried some options without success, with tightvnc, ultravnc and realvnc but all of them give error about syntax. Any native client suggested/recommended with windows 10 and oVirt? Tried also noVnc that works from a Linux client and so I'm sure all is ok at oVirt side, but from Windows 10 and chrome 61 I imported the certificate in trusted root authority but nevertheless I get the error Any hints? Thanks, Gianluca

Re: [ovirt-users] Cannot uplaod ot ISO domain
by Kasturi Narra 23 Oct '17

23 Oct '17

Hi Alex, Can you check if you have the following on your setup ? 1) gluster volume which will be used as ISO storage domain should have bricks connected using glusternw. 2) NFS time out is caused due to not having nfs.disable off on the volume. Can you try to set this and try again. 3) self hosted engine requires an additional NIC on the gluster network for the engine-iso-uploader to work sucessfully if ovirtmgmt and glusternw are on a different subnet. Even after having all the above if things do not work, you can just scp the file to /mnt/<storage-domain-uuid/>/images/11111111111111-1111- 1111-11111111…/ Hope this helps !!!
