I have a few cases where I need to share a filesystem (Read/Write) with
multiple DomUs.   Currently I use NFS to accomplish this task.  However, NFS
on Fedora 7 locks up under heavy traffic from time to time, forcing a
reboot.  Wouldn't want that on the Dom0.

Any one recommend a good way of sharing a file system in read/write with
multiple DomUs?

Have you tried tweaking nfs/nfsd? Failing that you could try with samba.

I successfully used both samba and nfs.

I use these nfs mount options:
udp,rsize=32768,wsize=32768,noatime
and exported with (async,rw,root_squash)

async perhaps could help you under heavy load.

for samba I use

cifs,sfu as mount options (I found cifs to perform better than smbalthough I noticed a bit of cpu overhead)


hope this helps
cheers
