Xen users - Oct 2005 - RE: Error Creating Domain:vbd:Segment phy:/dev/hda3 isin writable use

I''ve seen this happen before, not sure why.  I changed
''phy:'' to ''file:'' and it worked.  I later
rebooted and ''phy:'' worked again.  So you might try
''file:'' rather than ''phy:''.

  module /vmlinuz-2.4-xen0  ro root=/dev/hda3  console=tty0



Can anyone advise me what is the source of problem?

Make sure that the filesystem isn''t mounted on some directory in dom0. 
Also, make sure any other process isn''t using it...
