Hello Pasi,

Thanks for your inputs. I do not see "xm" cmd

-bash: xm: command not found

I do see "xe" cmd which has vif-unplug/vif-plug and vif-destroy/vif-create. I detached a vif via unplug and destroyed it. When creating a new vif, I do not see the option of vifname in it

xe help vif-create
command name            : vif-create
        reqd params     : device, network-uuid, vm-uuid
        optional params : mac, mtu
        description     : Create a VIF. Appropriate values for the device are listed in the parameter 'allowed-VIF-devices' on the VM. If specified, the MAC parameter is of the form aa:bb:cc:dd:ee:ff. If MAC is not specified the server will choose an appropriate MAC automatically.

Inputs appreciated.

You can use the "vifname" option on the vif line.
See "xm create --help_config" for more information.
