Is the Host expected to use *much more* CPU than the Guest?

I have a guest which uses about 20% to 30% of its CPUs (looking at htop). It's load average remains under 0.2.
However, the host for that machine uses around 60% of one of my CPUs.
Is that expected?
Possibly Important Factors:
I have just 4Gb of RAM assigned and generally use under 2Gb.
I run X-Windows in that guest with a resolution of 1920x1080 ("2K" which fits well on my 4K monitor). The 2D & 3D accelerate is turned on (I don't use 3D, though, just a console and a simple Qt app. on top of background daemons).
I assigned 32 CPUs to that machine, because I often compile on it and that way it goes FAST when I do so.
