libvirt users - Jan 2019 - Workaround for "internal snapshots of a VM with pflash based firmware are not supported" problem?

Hello World,

We were hit by the "internal snapshots of a VM with pflash based 
firmware are not supported" problem. Is there a workaround for it (for 
which revert works)? Another format perhaps?

Our use case: We have an image (Win10, UEFI) with some software 
installed. This image is used by Jenkins to execute some tests. After 
the tests, the image should be reverted to the original state. Jenkins 
uses the libvirt plugin to connect to and start/stop and revert the 
virtual machines. The images are in qcow2 format.

We've usually created a snapshot of the base state using "virsh 
snapshot-create-as" on the host system, but this is no longer possible.

What is the recommended workaround?

TIA and best regards
	Andreas
