afaik, uml still has a general problem with /dev/random entropy.
proxying /dev/random from the host sounds like a good solution.
is there work in progress ?

Better yet to implement a /dev/random entropy source in UML using the host
/dev/random.. it should be as simple as a kernel thread polling for write
on the UML /dev/random, pulling entropy in from the host as needed.
But if it is possible to proxy devices then obviously the above can easily
be done in a normal user process, moving entropy from the proxied random
device to the UML random device.
