Can't login into ovirt api
by Guilhem Berna 07 Jun '18

07 Jun '18

Hi, I'm trying to login into the ovirt api under ovirt 4.2 but the admin account user for the administration portal doesn't work. Maybe It created another api account at installation but i don't recall it. I'm unable to find any documentation regarding user management and api access. Can someone point me in the right direction ? Best regards, Guilhem Berna Sysadmin PHOSPHORE.si - [ https://www.phosphore.si/ | https://www.phosphore.si ]

The equivalence of the DiskAttachment ID and its relevant Disk ID should be intuitively documented.
by Joey Ma 07 Jun '18

07 Jun '18

Hi all, In these days, I was struggling to find the relationship among vm/disk/disk-attachment. I just found that the IDs of DiskAttachment and relevant Disk are the same, in the mapping phrase by [1]. This is a extremely helpful for connecting the disk and the disk-attachment, especially when updating a disk by its relevant disk-attachment instance. Nevertheless it's missing in the API document [2]. Adding a intuitive hint would be highly appreciated. Thanks.

Hi Marcin, do you see what could be the problem here?

Error attaching cd iso image from data domain
by Gianluca Cecchi 07 Jun '18

Hello, I'm with oVirt 4.2.3 (upgraded from 4.1 and compatibilities set to 4.2) I have a CentOS 7 VM. I correctly uploaded an iSO image to the disks of a data storage domain (iSCSI). Now in web admin portal I select the VM, then the 3 dots in top right, then change cd I'm proposed with the [Eject] line and into the dropdown I see the two iso images I have uploaded up to now. I select an image and then OK I get a window with title "Operation canceled" and content Error while executing action Change CD: Drive image file could not be found Do I have to edit any setting in my VM to be able to connect an ISO image this way? Or other things to check?

Ovirt node 4.2.1.1 patch/upgrade?
by Jakov Sosic 07 Jun '18

07 Jun '18

Hi guys, how do you upgrade ovirt nodes? I can't figure out the best practice from documentation. If I try `Check for upgrades` from oVirt Hosted engine interface, nothing happens. If I run `yum update` on an ovirt node, I get offered the following: ``` Installing: ovirt-node-ng-image-update noarch 4.2.3.1-1.el7 ovirt-4.2 643 M replacing ovirt-node-ng-image-update-placeholder.noarch 4.2.1.1-1.el7.centos ``` I can access all the CentOS packages if I run `yum update --enablerepos=base,updates,extras`. So, what is the proper way to do it? Thanks, Jakov

Asking about snapshot concept
by Terry hey 07 Jun '18

07 Jun '18

Dear all, I have a pre-allocated virtual machine. When i created a snapshot for that virtual machine, i found that it became thin-provision. And the size of the snapshot is same as the virtual machine. i would like to ask why these two behavior happened. 1. preallocated to thin provision 2. the size of snapshot is same as the disk size of virtual machine. Regards Terry
