Can one of the admins verify this patch?

[gnawux]

ok to test, hykins

[gnawux]

Do we need a fancy hello screen like this, @WeiZhang555 ?

[WeiZhang555]

Currently it will only log hyperstart version into runv log files, like:

What kind of hello screen do you mean? @gnawux

[WeiZhang555]

Improve the message a little bit:
