Thanks for your suggestions Keir and Robbie,

but it looks like /dev/urandom is used by sshd, but somewhere inside of sshd 
the stream is checked against a minimum
entropy. I don't think this is a an issue by getting blocked via /dev/random.

I'll try the userspace rngd, but - as you said - this shouldn't be the 
preferred method of getting more entropy into
the system.

Another thing i'll try (later at night, as the domU's are productive) is, to 
configure the domU's using the same pCPU's
targetting that the pCPU's cache is filled only sub-optimal and the latency is 
higher ... (maybe ;) )

I'll report here later.
