[I] Alma and Rocky 9.5 cloud images crashing on boot [cloudstack]
almostobvious opened a new issue, #10722:
URL: https://github.com/apache/cloudstack/issues/10722
### problem
Trying to create an instance from Alma and Rocky Linux 9.5 qcow2 "cloud images". Result for rocky is below
Trying to create my own image from ISO results in:
### versions
Cloudstack 4.20 host runs Rocky 9.5 on Xeon 2680v4 using KVM virtualisation.
### The steps to reproduce the bug
1. Use any of the latest "generic cloud" qcow2 images from Alma 9.5 or Rocky 9.5 to create a template. Or use any of the latest 9.5 ISO to try and install from ISO
2. Create instance with above template and boot
### What to do about it?
I don't have this issue with 8.x . Unfortunately Rocky and Alma have wiped all pre 9.5 (9.x) images and isos off all mirrors so I can't test 9.2 or 9.3.

@almostobvious
there were some discussions in the mailing list.
rocky9/alma9 has some requirements on guest CPU features.
therefore, the guest.cpu.mode should be set to host-passthrough or host-model
Please refer to https://docs.cloudstack.apache.org/en/latest/installguide/hypervisor/kvm.html#configure-cpu-model-for-kvm-guest-optional

Ok, host-model / host-passthrough didn't work at first, but then I noticed libvirt settings there too:
-
1. Selected host-model
2. The installation set `LIBVIRTD_ARGS="-l"` in /etc/sysconfig/libvirtd which I changed to `LIBVIRTD_ARGS="--listen"`
3. I also did `systemctl mask libvirtd.socket libvirtd-ro.socket libvirtd-admin.socket libvirtd-tls.socket libvirtd-tcp.socket`
This only worked after rebooting the host.

Hey thanks very much. I tried both host-model and host-passthrough but neither seems to have done anything.
What do I need to restart after changing this? To be sure I rebooted the 'host' after the changes.
Do I need to recreate templates?
