At first, I tried doing the binary install. The first problem is that it tells you to do a "depmod 18.104.22.168-xen". When you do, it says "depmod: QM_MODULES: Function not implemented". The major problem there is that when I start up the domU, it warns you that it's mounting the ext3 file system as ext2. I already lost one domU in the past because it wasn't ext3 and the file system corrupted when it didn't shut down properly, so I want ext3. Is there a way to make a ramdisk to get ext3? I tried using the same ramdisk that I'd made for the dom0, and it doesn't boot. Would it work if I copied my /lib/modules/22.214.171.124-xen to the domU? Ok, now I'm trying the source installation instead. And the first problem I'm encountering is that the list of packages to install says "gcc-3.3", but if you do that you don't actually get the "gcc" binary. You have to install "gcc" as well or instead. I'll let you know how that goes.
