I suggest that you have a look at the compute node logs when it fails to spawn. I suspect the problem is not Your images but something inside openstack

If I was to guess it’s probably missing UEFI firmware packages :)

I am trying to import a WIndows2012 Single disk VM, to OpenStack Ussuri, with glance and Qemu KVM.

In bare machine KVM I am able to import and boot this Windows VM which exported from rhevm hypervisor as  vhdx image.
what I have done is 

1. converted this windows  image from vhdx to qcow2
2.  root@MeghCtrol1:/home/cloud/CMOBB_APP#cirt-install --name WINDOWS --ram=1048 --vcups=1 --cpu host --hvm --dick path=BackUP2_CMAPP_disk_1_Windows_qcow2_imagefile,device=disk, format=qcow2,bus=virtio --graphics vnc --boot uefi

This uploaded the qcow2 image of WindowsVM to  KVM  hypervisor and its working. 

But when I do importing to openstack   unable to launch  instance from the image .

These are the steps I performed..

1. openstack image create "WindowsVM" --file CMAPP_disk_1.qcow2 --disk-format qcow2 --container-format bare --public
 
4.openstack image set --property hw_firmware_type=uefi --property os_secure_boot=required WindowsVM
 
5.openstack image set --property hw_firmware_type=uefi --property hw_disk_bus=ide WindowsVM
 
6.openstack image show WindowsVM

7. root@dmzcloud:/home/cloud# openstack image show WindowsVM|grep "properties"
| properties       | hw_disk_bus='ide', hw_firmware_type='uefi', os_hash_algo='sha512',
os_hash_value='753ee596980409e1e72d6d020c8219c56a6ada8b43f634fb575c594a245725a398e45982c0a1ad72b3fc3451cde62cceb9ff22be044863b31ecdd7893b049349',
os_hidden='False', os_secure_boot='required', owner_specified.openstack.md5='',
owner_specified.openstack.object='images/WindowsVM', owner_specified.openstack.sha256='' |
root@dmzcloud:/home/cloud#


Then  I logged into horizon dashboard,  from the images  selected the imported image and try to launch the instance.  With  a Flavour of 550 GB disk, 4 vcpus and 8GB Ram ..  

The instance spawning ran for 30 minutes and throws the error which I pasted first in the right top corner of horizon dashboard.  

How to solve this error and boot the Windows machine successfully ..
