hello Andy, thank you a lot for your help its working now, in fact I need to ask you some question please; 1- for the vcl can we call it a could service?? 2- if yes if we have two computation nodes dose it make a VM motion between them for example if there a computation node becomes overloaded and the second one has extra resource, and dose the end user feel that motion. 3-i'm thinking about a heterogeneous hypervisor i.e if we have two computational nodes one run KVM hypervisor and the second run esxi dose that supported by VCL and can we make a VM motion between two different hypervisor
is this setup support clustering for high availability to management node and for computational node I note that the images stored in the computational nodes and for example if this node failed then the images will not be available. thank you again Tariq On Mon, May 5, 2014 at 3:23 PM, Andy Kurth <[email protected]> wrote: > First, edit /root/.ssh/known_hosts and remove the line referring to the > VM.
