Advisable to install GNU Hurd on real hardware?

Hi,

As it says in the subject, is it advisable to install GNU Hurd on real 
hardware?

So far, I have been trying out GNU Hurd on QEMU/KVM; I read through the 
GNU Hurd documentation and it seemed to me that this is the most 
preferred way for trying out GNU Hurd. I also went through the 
available documentation on installing on real hardware, and I got the 
impression that this is probably not-so-recommended.

I really would prefer using a real machine over a VM. Therefore, I was 
wondering if I can get any opinions/insights on this. Is this something 
that is not advisable and should not be done, or is it that with a bit 
of care I can pull it off? I have old hardware available, so I can take 
the risk if anything goes wrong.

Looking forward to any inputs.

Thanks,
Saniya
