Thank you!

Shame on me!

I did the test with some few big files.
The inodes went so low, the booting Linux acquired the the rest.

Now i made a backup and created a new image with more inodes. 256k (262144) seems to be the default value. Now I use by hand:
  mkfs.ext3 -N 1048567 -b 1024 $NEW_IMAGE

...and the guest runs fine.

Best regards

running a Gentoo host and several guests (Xen 3.3.0, Gentoo
linux-2.6.18-xen-r12) there are some disk space spooks.

Other guests seem not to have access to all their disk space:
plone ~ # df . -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda1             4.0G  2.0G  1.9G  52% /
plone ~ # touch test
touch: cannot touch `test': No space left on device

The space is formatted in ext3 and if i mount the filesystem loopback in the
dom0 (after shutting down the guest), the whole space is usable.

Are you SURE that if you mount that particular filesystem in dom0 the
space is usable?
At first look it seems you might be out of inodes. Try a "df -i".
