Our experience at www.mythic-beasts.com showed problems with PCMCIA -
the installer hung here and we had to do a local disk install rather than nfs
with a modified installer.

I've contacted my colleague who actually did the install [he's a UML person
rather than a WBEL person] to see if we can get some documentation together to
help other people, he admitted it was a bit challenging.


Some other notes on WBEL under UML :-

To do the initial package upgrade with yum, you need to boot with more than
64MB of memory, otherwise yum crashes in an unhelpful way, 128MB RAM & 128MB
of swap worked okay.

To run java, you need to disable nptl, by moving /lib/tls to /lib/tls-dontuse

Note that upgrading glibc will put this back.


Our UML boxes are running on 2.4.25 & 2.6.5 kernels, and seem quite happy,
I've been using one as a low latency UDP proxy for game playing running a
highly threaded java program as the UDP relay and it's worked just like a real
machine.

Yours,

Pete Stevens
