I am able to reproduce this bug, but it seems peculiar to Ubuntu Natty
running in a virtual machine. When I step through the import process,
it looks like a failure to read the ZPOOL_CONFIG_HOSTID nvpair.
One way to help diagnose this problem would be to find it on a non-Natty
Additionally, a hostid of 0x007f0100 or 0x007f0101 means that you
probably have this bug:
This happens when the system hostname corresponds to a loopback entry
in /etc/hosts instead of a real network interface.
