That means a read system call failed.  It would be useful to know what
the errno value was - if you call get_description() on the error object
it should include this information.

I wouldn't be totally surprised if that didn't work since the shared
directory is probably FAT or NTFS and I'd guess fcntl locking isn't
supported there, but that should fail to open the database for writing.

Does this give the same error?

What does "mount" report from a command line on Ubuntu in VirtualBox?

The answers to the questions above would be useful.

Also, does this fail (simpleindex is in xapian-core/examples):

echo test|simpleindex tmp.db
