Is this  virtiio drivers applicable to launch   new  Windows  virtual
machines y from downloaded ISOs only ?   Or  as in my case   I am
exporting  from hyperV . The file I got   is vhdx file and I converted it
to qcow2 format.  Is the virtio drivers  hack required for exported(from
other hypervisors) Windows images also ? to import it to openstack.

if so     The step mentioned  here
https://docs.openstack.org/image-guide/windows-image.html


   1.
      1.

      $ qemu-img create -f qcow2 ws2012.qcow2 15G


Is this step needed for  other hypervisor exported  WindowsVM image which
converted by me already in qcow2 format ?   what the relevance of 15G in my
case of  qcow2 format  WIndows Single disk images  which is 17G in qcow2
format ?


2.   Step 2  In  mycase
what need to be  edited  here so that it successfully can be imported to
OpenStack and running .

# virt-install --connect qemu:///system \  --name ws2012 --ram 2048
--vcpus 2 \  --network network=default,model=virtio \  --disk
path=ws2012.qcow2,format=qcow2,device=disk,bus=virtio \  --cdrom
/path/to/en_windows_server_2012_x64_dvd.iso \  --disk
path=/path/to/virtio-win-0.1-XX.iso,device=cdrom \  --vnc --os-type
windows --os-variant win2k12 \  --os-distro windows --os-version 2012




That file size ( 17 GB  in qcow2 format, in bare KVM when I imported
successfully  its booted and disk space  around 500 GB ) .
