Many thanks for the explanation.
The problem really was that the VM tried to boot from the context CD.
After forcing the bootable CD as hda, everything worked as expected.
CONTEXT point in the template is missing, because I deleted it when
sending email.
Thought, it would not be safe to provide my public key for SSH to the
mailing list.
I am sorry that misled you about the lack of CONTEXT.
Once again I want to thank you for the help.
And I want to express my admiration for the project OpenNebula.
It is simple to primary installation, configuration, and superbly
documented.
Many thanks and success in the future development.
Best regards,
Aleksey Zolotukhin
