[libvirt-users] Error while starting the node on ESXi hypervisor

[varun bhatnagar]

Thanks a ton for the reply Matthias.
I am little confused here. How to add volume on my esx server using virsh?
I did SCP and copied my vmdk image to [datastore1]  testNode/cluster.vmdk
and also modified my xml file as you suggested. Now when I tried starting
the node it gave me an error message saying:

"error: Failed to start testNode
error: internal error: Could not start domain: GenericVmConfigFault -
Failed to start the virtual machine."

How to resolve this?

Regards,
Varun
