Q: What would happen, if I buy an external random number generator?
There are USB and PCI devices on the market which start at 200 EUR. But
I can use such a device in only one domain? The other domains won''t
profit from the extra entropy?
Or can I mount /dev/random over nfs for all other domains? Would that
work? I would feed one domU with the external generator and use
/dev/random in all other domU''s over nfs on the same machine...
Any ideas/comments welcome.
Greetings,
Robert
