Need help running fio benchmark using static VM configuration

I am running a fio test against a pair of static VMs in an OnPrem environment. Oddly, PKB assumes the VM to be from GCP environment. I have tried specifying os_type as "rhel" in the static VM configuration, but that does not help. The same static VM definition works well with iperf tests.

Could someone please review my configuration file and let me know the error?

**Config file**
```
# cat static_configs/fio_config.yaml
static_vms:
- &vm1
ip_address: x.x.x.x
internal_ip: 192.168.150.201
user_name: root
ssh_private_key: /root/.ssh/id_ecdsa
zone: local
os_type: rhel8
disk_specs:
- mount_point: /test_data
- &vm2
ip_address: y.y.y.y
internal_ip: 192.168.150.203
user_name: root
ssh_private_key: /root/.ssh/id_ecdsa
zone: local
os_type: rhel8
disk_specs:
- mount_point: /test_data

benchmarks:
- fio: {vm_groups: {default: {static_vms: [*vm1]}},
flags: {against_device: True}}
- fio: {vm_groups: {default: {static_vms: [*vm2]}},
flags: {against_device: True}}

```
