Hi, I'm trying to get Nova on Hyper-V to work with vhdx Glance images. The images works well when started on Linux KVM, but on Hyper-V I get the following error in nova.log.
2017-02-21 16:38:18.236 7124 ERROR nova.compute.manager [instance: ca6e66e5-aba3-43c9-8150-9beca16e0d91] nova.exception.InvalidImageFormat: Invalid image format 'vhdx'
I can boot other images in VHD format fine on the same hypervisor. We run Newton release (via Kolla) and use the nova Windows components from https://cloudbase.it/downloads/HyperVNovaComputeNewton1401.zip. Any idea what could be the cause of this? As far as I understand it vhdx should be supported.
My nova.conf looks like this:
