If the Template is a UEFI enabled , Cloudstack should check if the template is UEFI enabled or not and populated the necessary settings for root disk and nic adapter yum install libguestfs-tools virt-inspector --format=raw -a noble-server-cloudimg-amd64.img 2>/dev/null | grep -i '<uefi>true</uefi>' virt-inspector -a AlmaLinux-8-GenericCloud-UEFI-latest.x86_64.qcow2 2>/dev/null | grep -i '<uefi>true</uefi>' -- This is an automated message from the Apache Git Service.
