Hi,

I had the same issue but with an earlier Cloudstack Version on some hosts, try to to do the following as described in this thread: https://www.mail-archive.com/search?l=users@cloudstack.apache.org&q=subject:%22uefi%22&o=newest&f=1

There are two main files which would need to be created/edited: /etc/cloudstack/agent/uefi.properties and /etc/libvirt/qemu.conf. After that, perform a restart of cloudstack-agent. In the database, you should see an entry in table host_details showing that this particular host has uefi enabled.

Best,

Mevludin

Hi

I have two Almalinux 8 hosts, both identically configured and uses same package versions. I just upgraded to 4.19.0.1, as well as upgrade cloudstack-agent accordingly. My one host now fails to connect and remains in "Disconnected" state. While the other connects successfully.

One the host that fails, the agent log shows this:

---

And the log just remains stuck there.

One the connected host it shows:

After this:

2024-04-03 10:18:51,949 INFO [kvm.resource.LibvirtConnection] (main:null) (logid:) No existing libvirtd connection found. Opening a new one

The disconnected host does not want to connect. While the other does.

Can someone please assist with this, please? Both host have the following versions:
