Hi Stanley This look like limitation from the el9 side https://www.phoronix.com/news/RHEL-9-x86-64-v2-Plans https://developers.redhat.com/blog/2021/01/05/building-red-hat-enterprise-linux-9-for-the-x86-64-v2-microarchitecture-level#recommendations_for_rhel_9 https://forums.rockylinux.org/t/rocky-linux-9-virtualbox-kernel-panic/6692/5 As a workaround, Please perform the following changes 1. Edit the file present on the kvm hosts “/etc/cloudstack/agent/agent.properties “ guest.cpu.mode=host-passthrough 2.

Hi Kiran, Thanks for the solution. The issue is resolved after adding guest CPU configurations to the cloudstack agent file.
