Error: Adding new Host to ovirt-engine

Hi,
Can't add new host to ovirt engine, because the following error:

The error appears to be in

be elsewhere in the file depending on the exact syntax problem.

GWT in project ovirt
by anater78＠gmail.com
Hello!
I plan to develop ui plugins.
Does it make sense to use GWT?
Do you plan to use GWT in the project in the future?
Do you plan to switch to another technology?
If something has already been written about this or there is a roadmap, I ask for a link.
Thank you!

oVirt engine builds on el9
by Michal Skrivanek
Hi all,
we are going to bundle maven dependencies in a new package ovirt-engine-build-dependencies. This allows us to use CBS to build ovirt-engine as any other package, and enable el9 builds.
This is just a build dependency, there's no change to a built product.
We will now start publishing el9stream builds of ovirt-engine and start switching testing to el9
Thanks,

oVirt bug reports to move from bugzilla to github issues in future
by Michal Skrivanek
Hi all,
as a final stage of out gerrit to github transition that started ~9 months ago we are planning to eliminate the use of bugzilla.redhat.com for all oVirt projects (bugs with Classification: "oVirt") and use the native issue tracking in github as well. We used to have integrations with gerrit and bugzilla that we moved to github actions instead, and the overhead (and notorious slowness) of bugzilla.redhat.com becomes the only "benefit" of using it these days.
There's about 50 bugs total left in oVirt bugzilla so it's not that much to move, the biggest change would be that the new bugs are to be filed elsewhere.
This is just a heads up for now, we haven't set a cut off date just yet, but you can expect this change in the coming weeks.
Thanks,
michal

vbmc - simple IPMI support for oVirt VMs
by Michal Skrivanek
Hi all,
I wanted to share the news about a new oVirt (mini)project - vbmc[1]. It's fairly small and simple, but it may be handy if you'd like to treat oVirt VMs as bare metal machines controllable via IPMI. It only implements power on, off, reboot, and set boot order, but that should be enough for bootstrapping over pxe.
Thanks,
michal

Re: Starting with oVirt
by Strahil Nikolov
Hardware wise - try one server with CentOS Stream 8 and check that all hardware is recognized and works as expected.
You can start with a single server and expand further. RH dropped Gluster Support for their downstream solution (RHV) , yet oVirt doesn't have plans to get rid of it.
The easiest for you would be to use SAN or NAS as storage. If that's not an option, you can use GlusterFS - which is a distributed File System . The latter needs a 10GBE NICs (1 Gigabit is OK, but don't expect much speed when writing in the VMs).
oVirt supports GlusterFS in 2 modes:- replica 1 - a mode intended for a single host setup- replica 3 (where you have 3 copies of your data) - where the storage nodes should be multiple to 3. You can also have compute-only oVirt nodes (those do not participate in GlusterFS but have CPU & RAM to host VMs)
If you configure HA VMs , the engine will take care to recover them on another host. If you loose 2 out of 3 servers - GlusterFS will loose majority of the bricks (term for a host+mount point combination) and will shutdown until majority is restored.
In all cases - you should segregate the network for Storage and Compute workloads (Gluster/NFS on separate network).
P.S.: iSCSI is also a storage option.
Best Regards,Strahil Nikolov

Hi,
Our company is planning oftaking oVirt in into our environment. We would have a few questions for that if you could guide us.
Hardware:
What would be the minimum configuration for us using oVirt?.Idea would be to replace all our current Linux and Windows servers withoVirt. There are currently 24 servers in use.
The goal would also be that the virtual servers could be migrated live and also in the HA configuration, i.e. if onehardware crashes execution continues on the other.
As far as I understand Ovirt enables this?
So we would like to know what kind ofhardware (minimum) we should have for this size of environment?
Storagin:
Do all machines need a lot of hard disk space or is it enough to have only one or two? I'm referring to shared storage. Can you also have storagin as HA?
Host:
What happens to HOST1 and HOST2 virtual machines if the oVirt host server crashes?
Do they continue to operate without it, or do they crash at the same time?
Thank You!
Teemu S.
