No, but you don't need 3.4.7.  The 3.5 update should already contain
the same patch that fixed the libvirt issue.  Specifically:

CPU-hotplug-cpusets-suspend-Dont-modify-cpusets-during.patch

which is definitely applied to the 3.5 F17 update.

Oops, misunderstood your response the first time.

Yes, I agree the 3.5 update will have the same fix. I suggested 3.4.6-3 so that we can get the fix sooner since 3.5 seems to be stuck (due to a problem with cinnamon, according to the CI report).

(I am still seeing the issue with 3.4.6-2, which is what we would expect).
