[one-users] REQUIREMENTS attribute in VM definition file howto

[Vladimir Kozhukalov]

I have a problem with defining REQUIREMENTS attribute. Ihave one KVM node
and a VM template. I try to define in the template

REQUIREMENTS = "HOSTNAME = \"virtual1\"" & "HYPERVISOR = \"kvm\""

onevm create myvm.template works fine and my VM is correctly deployed and
startted on my node, but when I define my REQUIREMENTS attribute in the
following manner

REQUIREMENTS = "HOSTNAME = \"virtual1\"" & "HYPERVISOR != \"kvm\""

I am waiting that my KVM node is not matching this definition (HYPERVISOR !=
\"kvm\"), and absolutly surprising for me  that VM  was again successfully
deployed and started on my KVM node. When I try to know how my REQUIREMENTS
definition had been parsed  I see the following
