Not able to reproduce with the following modified config:

Dropping from os section:

<loader readonly="yes"
type="pflash">/usr/share/edk2.git/ovmf-x64/OVMF_CODE-pure-efi.fd</loader>
<nvram
template="/usr/share/edk2.git/ovmf-x64/OVMF_VARS-pure-efi.fd">/var/lib/libvirt/qemu/nvram/fedora-org-drm-qxl-base_VARS.fd</nvram>

Dropping custom -trace parameter and using nec-xhci instead of qemu-xhci
(my libvirt doesn't like the new one on fedora 26).

1) Does the assert trigger right at startup? Or how is it triggered?
2) Does your setup work when dopping the assertion?
