FreeBSD 11.2 slow under KVM/Qemu

Hello all,

I have a virtual machine that is running under Qemu on an IBM PPC
server that is al lot slower than its equivalent running on hardware
on an AMD Phenom quad core quite aged. A small overhead from the
virtualization is normal, though this one is a bit too much.
I've seen this in my qemu log:

2018-11-22T12:21:59.087171Z qemu-system-ppc64: System page size 0x1000000
is not enabled in page_size_mask (0x11000). Performance may be slow

Is it something already known?
