qcow on LVM‽ Why‽
by Thorsten Glaser 06 Mar '20

06 Mar '20

Hi *, I’m a bit frustrated, so please excuse any harshness in this mail. Whose idea was it to place qcow on logical volumes anyway? I was shrinking a hard disc: first the filesystems inside the VM, then the partitions inside the VM, then the LV… then I wanted to convert the LV to a compressed qcow2 file for transport, and it told me that the source is corrupted. Huh? I had already wondered why I was unable to inspect the LV on the host the usual way (kpartx -v -a /dev/VG/LV after finding out, with “virsh --readonly -c qemu:///system domblklist VM_NAME”, which LV is the right one). Turns out that ovirt stores qcow on LVs instead of raw images ☹ Well, vgcfgrestore to my rescue: - vgcfgrestore -l VG_NAME - vgcfgrestore -f /etc/… VG_NAME The image was still marked as corrupted, but exported fine. I could not write it back to the LV as preallocated, which seems to be what ovirt does, because qemu-img doesn’t wish to do that when the target is a special device (not a regular file). Meh. Does ovirt handle raw images on LV, and if so, how can we enable this for new VMs? If not, whyever the hell not? And whose “great” idea was this anyway?

Windows deployment
by eevans＠digitaldatatechs.com 06 Mar '20

06 Mar '20

I have a Windows Deployment server that works with Hyper-V. I am tryng to see if it will bare metal provision to Ovirt. I have the necessary drivers loaded and initially it gets an IP and starts the installation. When it comes to the screen starting setup, I get an IP error. I have included a screenshot. Has anyone see this before? I also considered provisioning from Foreman but I would rather use what I have instead of recreating the entire installation. Any help would be appreciated. Here is a link to the actual error: ftp://ftp.digitaldatatechs.com/pub/Windows%20Provision.jpg

subnets
by eevans＠digitaldatatechs.com 05 Mar '20

05 Mar '20

I have a network in place with several subnets, one for iscsi and one for virtual pbx and VoIP phones. I use the iscsi in Ovirt, but I cannot get Ovirt to recognize and use the physical vlan 3 network for phones. If I add it and the subnet, Ovirt will make give it an IP, but it's an isolated network with no connectivity to the other vm's or the Internet. I have read several topics on this but I can't get it to work properly. Any help would be appreciated. Thanks.

Debian 10 template - cloud init not working
by Sakari Poussa 05 Mar '20

05 Mar '20

Hi, I have tried centos7 & 8, debian 9 and ubuntu 18.04 template based VMs with cloud init (Initial run/use cloud init) and they all work as expected. However, the debian 10 template based VM seems *not* to execute the cloud init at all. It boots but hostname is not set and users / password are not set. You can't log in since there is no users and passwords/keys. Is this a known issue? Or am I missing something? The templates are from ovirt-image-repository storage domain. I have also created newer debian 10.3.0 template via ovirt.image-template ansible role. Results are the same. I am running ovirt 4.4-pre. Thanks, Sakari

When oVirt was deployed in our environment by previous engineers, the DWH was installed as Basic. I would like to change this to Full, to get the daily stats, as this is now empty due to the scale. If it's completely empty, perhaps there is some other problem, not the scale. To further debug this, check that both the engine and dwh access the same database (this should be ok by default, but perhaps you used non-defaults) by checking the credentials they use in their conf files: grep DWH_DB /etc/ovirt-engine/engine.conf.d/*conf grep DWH_DB /etc/ovirt-engine-dwh/ovirt-engine-dwhd.conf.d/*conf You might also check /var/log/ovirt-engine-dwh/ovirt-engine-dwhd.log .

Changing the Data Warehouse Sampling Scale
by anton.louw＠voxtelecom.co.za 04 Mar '20

04 Mar '20

Hi Everybody, I have a question. When oVirt was deployed in our environment by previous engineers, the DWH was installed as Basic. I would like to change this to Full, to get the daily stats, as this is now empty due to the scale. Is this just as simple as described in the following article: https://www.ovirt.org/documentation/data-warehouse/Changing_the_Data_Wareho… Are there any precautions I should take, and has anybody else ever done this before? Thanks a lot
