Ach! I had /vz mounted with options "nosuid,nodev,noatime" as suggested
in the user wiki. Install of openssh RPM into /vz/vztmp/vztree complains
with "PRNG is not seeded" instead of generating the keys.

Fixed with "mount -o remount,dev /vz", tested OK.
Better (& FASTER!) fix: "mount -t tmpfs -o size=500m,noatime none /vz/vztmp"
This change fixed other problems with /dev/null which were showing up in
the installation log too.

Thanks again for pointing me to the solution.
