I've had this problem for a while, and I just figured it was due to VFIO
GPU passthroughs being generally incompatible with S3. I currently just
set a sleep inhibitor while my VM is running so I don't accidentally put
the host into sleep while it's still running. I've been trying to add it
to my libvirt hooks, but libvirt seems to detect when a process is
forking and hold on to the subprocess regardless, so no luck there.

After I start and then shutdown my passthrough VM and then suspend the
host, it won't wake from suspend anymore. As in, once in S3, pressing
the power button simply has no effect. I have to press the reset
button (and sometimes that doesn't work either) and restart the
machine. Suspend works correctly if I never start the VM.
Has anyone seen this issue before?
Hardware: i5-4690, ASRock H97, GTX 1060.
Software: Fedora 24, kernel 4.7.7, qemu 2.6.2, GTX 1060 video and
audio taken by vfio-pci, OVMF VM with Windows 10 managed by libvirt.
Try a v4.8 kernel, I was doing some testing on a Fedora v4.7 system and
seeing a number of strange things after running a VM with device
assignment. Disabling KVM resolved the problem, but is clearly not a
useful workaround. I wasn't able to reproduce on v4.8, which makes me
think KVM in v4.7 might have some issues.
