looking into the upstream linux sources I realized that the PVHVM

purpose? Shouldn't the frontend drivers, xen/platform-pci.c etc. be
configurable without having to enable CONFIG_PARAVIRT?

I suppose that would be possible but I don't think it's a useful
configuration because you would lose PV spinlocks for example.

Having no pv spinlocks on a single vcpu HVM guest isn't so bad. Having
no pv-drivers for disks and networking is worse.
