Unable to power on a VM after provisioning - PXE boot

Hi, We are facing issues where VM’s is not powered on after provisioning. We receive provisioning is success, but VM is left in powered off state. This occurs on 50% of VM’s provisioned, Especially on Windows. Could you let us know which logs to look to troubleshoot further on this issue as this issue is intermittent.
We use PXE boot for provisioning, So VM is rebooted twice during the provisioning.
MIQ is not sending request_vm_start request for second time. Do let me know if you need more information.

@tinaafitz Thoughts?
