I have a libvirt/qemu/x64 UEFI guest running Windows 10. The problem is that it starts successfully every other time.
When I issue a guest start commmand (any libvirt method) 1st time, the guest starts executing UEFI and is then shut down before trying to boot from storage. I verified by setting it to boot W10 install media first.
When I start second time, it boots normally.
A good start/shutdown looks like this: good qemu start A bad start looks like this: bad qemu start
I'm looking for advice to add more logging to see the nature of my problem
