Re: FW: FW: [Xen-users] Xen and OpenSSI

What's the error message this time? The reason I ask is that my
version of node1 has the loop devices (/dev/loop{0-7}) -- the SSI
kernel (the one from the OpenSSI site) has the loop devices built-in.

I believe another reason the mkinitrd can fail is due to low memory. I
seem to recall that when I was first setting it up I tried a 64MB
machine (maybe less) and it didn't like that at all.

Option-C will probably be making an SSI kernel package available at
some point in the near future, and that will have a set of modules
with it, but that's not going to help you now.
