GitHub user jeanvetorello closed a discussion: Windows 11 ISO does not boot
with UEFI (OVMF) in KVM hosts
### problem
Hello,
I am trying to deploy a Windows 11 VM on Apache CloudStack (KVM hypervisor)
using UEFI boot with OVMF.
However, the VM does not boot from the ISO. The TianoCore (OVMF) firmware
screen appears, I select the CD-ROM option, but it immediately returns to the
boot menu instead of loading the Windows installer.

### The steps to reproduce the bug
1.Install CloudStack agent with ovmf package on Ubuntu 24.04 host.
2.Configure /etc/cloudstack/agent/uefi.properties:
```
guest.nvram.template.secure=/usr/share/OVMF/OVMF_VARS_4M.ms.fd
guest.nvram.template.legacy=/usr/share/OVMF/OVMF_VARS_4M.fd
guest.nvram.path=/var/lib/libvirt/qemu/nvram/
guest.loader.secure=/usr/share/OVMF/OVMF_CODE_4M.secboot.fd
guest.loader.legacy=/usr/share/OVMF/OVMF_CODE_4M.fd
```
3.Register a Windows 11 ISO in secondary storage.
4. Create a VM with:
virtual.tpm.version
2.0
virtual.tpm.model
tpm-tis
UEFI
SECURE
Firmware: OVMF (with TPM 2.0)
5. Global Settings
enable.additional.vm.configuration true
allow.additional.vm.configuration.list.kvm devices,tpm,backend
6. Start the VM.
