Hi all,
I've been curious about using hardware true random numbergenerators
in my VM clusters. This got me wondering about the VM's /dev/random source... If I setup a hardware TRNG on the host, would the VM's
also
benefit from it?
Xen VMs would not be able to benefit from it. I don't know about KVM.
Would you be able to elaborate on why not? I know Xen and KVM
differ, but this
is not a topic I have seen discussed at all before, so any insight
would be
helpful and appreciated! :)
Because we don't have a paravirtualized interface to export the randomness to the guest. It would be a nice small little project to do that though.
Ah, ok. I'm an admin, not a programmer, so I am not sure what would be needed. Given how popular VMs are now, I can imagine it would be a nice feature to have. If it's a "small" project, then all the better! :)
Thanks!
