[one-users] onehost problem with kvm

Thu Jun 24 06:06:52 PDT 2010

Hello,

I made the same mistake. That path in the git repository is for the
development version, the foundation for 1.6, so it is normal that the
files are different. To check the file that comes in the tar.gz you
have to look at one-1.4 branch, or more specifically its release tag:
http://dev.opennebula.org/projects/opennebula/repository/revisions/release-1.4/entry/src/im_mad/kvm/kvm.rb

This bug is solved in one-1.4 branch but 1.4.1 tar.gz is unfortunately
not yet released.

Bye
