what host os version or ovirt node version I choose for my production setup
by dhanaraj.ramesh＠yahoo.com 13 Apr '21

13 Apr '21

We had done successful POC of ovirt node & HE with 4.4.5 version and now planning for production. However since 4.4.5 ovirt node& HE based on centOS 8.3, yet Red hat announced CentOs8.3 EOL by End of this year, is there any progress/plan to release ovirt nodes with CentOS stream soon? if we choose to go with Centos 8.3 based oVirt node, what could be the consequences in near term especially when it's come to next production release upgrade? Kindly suggest me which Host version I should choose for Production setup?

Adding physical RAM to the hosts
by David White 13 Apr '21

13 Apr '21

As readers will already know, I have three oVirt hosts in a hyperconverged cluster. I had a DIMM with too many errors on it, so I scavenged from a spare server that I had in my office precisely for this purpose. I went ahead and replaced all of the RAM, because the DIMMs in my spare were a different speed. While I was at it, I doubled the RAM on this 1 oVirt host. So now, two hosts have 32GB each. And the 3rd host now has 64GB. So total, I should have 128GB of RAM available to the cluster. The engine recognizes that the host now has 64GB of RAM. Screenshot below: [Screenshot from 2021-04-12 19-59-59.png] However, the engine dashboard still shows that only ~93GB of RAM are available to the cluster (screenshot below). [Screenshot from 2021-04-12 19-58-15.png] Should I be worried that the oVirt dashboard hasn't updated to ~128GB (or a bit less, I guess)? Do I need to do anything else?

Glad that it worked, and thanks for the report! I strongly recommend that you spend some time investigating what/who/why it was changed. This is most likely a mistake someone made at some point. It might be broader than just this file, or it might be some other kind of problem (e.g. a machine crashed in the middle of engine-setup and left files corrupted). If you can't find why/who, and suspect it's a bug, we'd definitely like to get more information. Some things you can check (other than usual site-specific things like who logged in, when you changed stuff there, etc.): - All /var/log/ovirt-engine/setup/* logs, their timestamps, and their contents (e.g. grep them all for "OVESETUP_ENGINE_CORE/enable"). - /etc/ovirt-engine-setup.conf.d/20-setup-ovirt-post.conf* - the file itself, and backups (made by engine-setup or otherwise), timestamps etc. - /etc/ovirt-engine/uninstall.d/* - engine-setup (and other related tools) keep there information about all files it created/chagned - mainly used by engine-cleanup Good luck and best regards, -- Didi

Ovirt with Oracle Linux 8.3 & Cockpit - Direct Luns
by hansontodd＠gmail.com 12 Apr '21

12 Apr '21

Is Ovirt compatible with Oracle Linux 8.3? I have KVM & Cockpit running on Oracle Linux 8.3 but don't see a way to map direct luns (like RDM's) to the VM in the Cockpit interface. Do I need to move back to Centos 7.x or RHEL 7.x with Ovirt to be able to use direct luns? Can Ovirt and Cockpit coexist?

ipxe support with Q35 chipset and UEFI
by Gianluca Cecchi 12 Apr '21

12 Apr '21

Hello, I'm doing some tests with iPXE (downloaded latest version cloning the git repo some days ago). I'm using oVirt 4.4.5 with VMs configured with different chipset/firmware type. It seems that using dhcpd.conf directive of type if exists user-class and option user-class = "iPXE" { filename "http://my_http_server/..."; } else { ... } the VM boot catches it when I use Q35 Chipset with BIOS, while it goes inside the "else" section if using Q35 Chipset with UEFI (not the SecureBoot one) Does this mean that the Q35 UEFI doesn't support iPXE? BTW: if anyone has suggestions about an utility that can let me boot via network and give the user a general menu from which he/she can go and choose standard pxe with bios or uefi boot, to be able to install both Linux based systems and other ones, such as ESXi hosts, both with BIOS and UEFI, it is welcome Gianluca

Do you have "everything" (engine, dwh, etc.) on the same machine, or different stuff set up on different machines? Any chance you manually edited /etc/ovirt-engine-setup.conf.d/20-setup-ovirt-post.conf for any reason? I see there: 2021-03-18 22:45:25,952+0700 DEBUG otopi.context context.dumpEnvironment:775 ENV OVESETUP_ENGINE_CORE/enable=bool:'False' This normally happens only if the engine was not configured on this machine.
