installing qemu in fedora-29 template clone

[tlaurion]

Qubes OS version:

R4.0

Affected component(s):

qemu, xen-qubes-vm, xen-libs

Installing qemu depends on xen-qubes-vm-2001:4.8.4-7.fc29.x86_64 which requires xen-libs = 2001:4.8.4-7.fc29 while xen-libs-4.11.0-7.fc29.x86_64 is installed.

Forcing sudo dnf --allowerase qemu downgrades to an unbootable xen-qubes-vm-2001:4.8.4-7.fc29.x86_64 based template.

---

Steps to reproduce the behavior:

sudo dnf install qemu
sudo dnf install --allowerase qemu

Expected behavior:

install a functioning qemu vm usable for testing

Actual behavior:

forcing --allowerase downgrades to unbootable qube based on this template. Template doesn't boot either.

This is duplicate of #3945 . Will be fixed in Qubes R4.1, unfortunately no easy way to safely apply the fix for R4.0 (requires recompiling all the packages with Fedora's xen-libs and not screwing any dependency in the process).
