HeinzM opened a new issue, #250:
URL: https://github.com/apache/cloudstack-terraform-provider/issues/250
## Feature Request
**Summary**
Add support for specifying the VM **boot mode** (`Secure` or `Legacy`) in
the `cloudstack_instance` resource, alongside the existing `uefi` option.
---
### Current Behavior
At the moment, Terraform users can enable UEFI booting with:
```hcl
uefi = true
```
However, there is no way to control the boot mode, although the CloudStack
API supports this via the bootmode parameter in deployVirtualMachine.
### Proposed Enhancement
Introduce a new optional argument boot_mode to the cloudstack_instance
resource.
```hcl
resource "cloudstack_instance" "example" {
name = "vm-secureboot"
service_offering = "Small Instance"
template = "ubuntu-uefi"
zone = "zone1"
network_id = "net-123"
uefi = true
boot_mode = "Secure" # or "Legacy"
}
```
Behavior
- If uefi = false, boot_mode should be ignored or validated as unsupported.
- If uefi = true and boot_mode is not provided, default to "Legacy".
- Accepted values: "Secure", "Legacy" (case-insensitive).
- The value should map directly to the CloudStack API field bootmode.
### Relationale
UEFI + Secure Boot are increasingly required in enterprise and compliance
environments.
CloudStack supports these features natively since v4.14+( according to
Cloudstack API Documentation), but Terraform users cannot currently configure
Secure Boot declaratively.
Adding boot_mode makes the Terraform provider feature-complete for
UEFI-capable VMs.

bootmode)

### Implementation Hints
_func resourceCloudStackInstance() *schema.Resource_ :
```go
"boot_mode": {
Type: schema.TypeString,
Optional: true,
ValidateFunc: validation.StringInSlice([]string{"Secure", "Legacy"}, true),
},
```
Map this field to the CloudStack API parameter bootmode.
There is already a conditional for the uefi value in _func
resourceCloudStackInstanceCreate(d *schema.ResourceData, meta interface{})
error_.
```go
if d.Get("uefi").(bool) {
p.SetBoottype("UEFI")
p.SetBootmode("Legacy")
}
```
But bootmode is statically set to "Legacy"
### Acceptance Criteria
- boot_mode can be set on cloudstack_instance.
- The parameter is passed correctly to deployVirtualMachine.
- The VM’s actual boot mode is reflected in Terraform state.
- Documentation and examples are updated.
