[Xen-devel] Xend doesn't allow domain creation with multiple empty CD-RO
This is a very simple bug. "xm create" complains when you try to use a line
like this in your cfg to specify multiple unused virtual CD-ROMs:
disk = [ 'file:/servers/customers/test.img,hda,w', ',hdc:cdrom,r',
',hdd:cdrom,r' ]
...by giving this error:
Error: The file "None" is already used
I don't know if it's the proper way of going about it, but this patch
(against a xen-unstable from a week or two ago) seems to address it.
