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

[Carlos Martín Sánchez]

Hi Vladimir,

I think your problem is that you have to define your requirement as one
string.
Try
REQUIREMENTS = "HOSTNAME = \"virtual1\" & HYPERVISOR != \"kvm\""
instead of
REQUIREMENTS = "HOSTNAME = \"virtual1\"" & "HYPERVISOR != \"kvm\""

Regards,
Carlos
