Thanks Wei, yes, that is my understanding as well.

Right. The value might be updated each time when cloudstack-agent is

Great,
When you are done upgrading all hosts then you can revert the original
/etc/redhat-release. If it's identical on all hosts it should be fine,
if
it still complains you can have a look in the DB.

Hi Nux,
thanks for your replay, I did a first test in changing the OS and I
was
able to add the host again.
Many thanks,

Betreff: Re: OS Upgrade Rocky 8.5 to 8.9
Hi,
Cloudstack matches the Rocky OS by means of 2 things:
- the contents of /etc/redhat-release and
- the contents of cloud.host_details (where existing entries are)
The script who does this is
/usr/share/cloudstack-common/scripts/vm/hypervisor/versions.sh
I am not 100% this will work, but try to adjust /etc/redhat-release
on
the new server to be like the old ones, see if that yields any
improvements
to your problem.
You should definitely NOT fiddle like this in production, if you have
a
test environment, that'd be great.

Hello Community,
I have a Cluster with Rocky 8.5 hosts, libvirt 6 and CloudStack
Agent
4.18.0. I upgrade the first host to Rock 8.9 with libvirt 8, now the
agent is not starting on the host.
In the log I found "ERROR [kvm.resource.LibvirtConnection]
(Agent-Handler-1:null) (logid:) Connection with libvirtd is broken:
invalid connection pointer in virConnectGetVersion"
I know that I cannot mix OS versions in a cluster but I thought this
is only valid for major versions like Rock 8 / 9.
When I add the host to a new create cluster the host is successfully
added.
Any idea how to upgrade my existing cluster without interrupting the
instances to Rock 8.9?
Any help would be appreciated, thanks
BR, Christian
