>Description:
Using XenCenter on both XCP and XenServer hypervisors you can choose to deactivate (simulate unplugged interface) any interface assigned to a VM. On Linux VMs this seems to work without issue. The option to Deactivate an interface is not available unless the FreeBSD XENHVM server is also reporting network interface data to the hypervisor with the following scripts (which require sysutils/xen-tools)
