I would recommend this...

Do your installation on 1st level VM.  After that is complete, IPL it on
your 2nd level VM.  Performance will still likely stink, but at least you'll
have a running, er, crawling, system.

Subject: Re: NFS pb while using OSA Gigabit at 2nd level of VM


Ok, I resume:
      I'm testing installation of different distributions of Linux on top
of a zVM 4.2:
      -SuSE Linux for S/390 version 7.2 running the 2.4.7 kernel
      -RedHat Linux for S/390 version 7.2 running the 2.4.9 kernel

I'm using NFS installation mode through an OSA Gigabit card
(NB by the way, the NFS server is sharing the OSA card with the Linux
images)
      -at first level of VM: no specific problem
      -at second level of VM (Linux is a guest of a VM guest):
            .installation of SuSE works fine, but with poorer performances
than at first level
            .installation of RedHat: fails in most (> 95%) of the cases,
due to VERY VERY poor rate of the OSA card

I've tried to use an OSA Fast Ethernet card, with same result for RedHat
install.... I really suspect I did someting wrong on VM side....
which lead RedHat not to behave as well as SuSE...
But what?

Any kind of advice, somebody?
