hello, I wonder how I can see the (on-disk) data changing in a running domainU. I tried to do it, but the data looking from outside remains intact, no matter what I modified inside the domainU. I did it this way: I use a file-based rootfs (got from ttylinux), and created a domainU on that rootfs. Everything was fine. Then from domain0, I mounted that "rootfs" file in read-only mode, with this command: "mount -o loop -o ro rootfs /mnt". After that I could see the data inside the rootfs. Then I suppose that from outside (domain0), I can watch for the data of domainU changing in realtime. To test, I just did a comand like this from inside domainU: "ls /etc > /root/etclist", and created a "etclist" in "/root". Then I supposed that from domain0, in a mounted "/mnt" above, I could see the new file created as "/mnt/root/etclist", but I was disappointed not to see anything at all. So clearly everything made changed inside domainU cannot be seen from outside (domain0). Anybody can please explain to me why, and if possible, how could I watch data of domainU (in realtime) from domain0?
