Centos 7
Xen4CentOS - 4.6.1
Open vSwitch

When i specify custom name of the domU NIC than it refues to start

vif = [ 'vifname=vNIC1' ]

libxl: error: libxl_exec.c:118:libxl_report_child_exitstatus:
/etc/xen/scripts/vif-openvswitch online [10168] exited with error status 1
libxl: error: libxl_device.c:1084:device_hotplug_child_death_cb: script: ip
link set vif38.0 name vNIC1 failed
libxl: error: libxl_create.c:1381:domcreate_attach_vtpms: unable to add nic
libxl: error: libxl.c:1591:libxl__destroy_domid: non-existant domain 38
libxl: error: libxl.c:1549:domain_destroy_callback: unable to destroy guest
with domid 38
libxl: error: libxl.c:1476:domain_destroy_cb: destruction of domain 38

When removed the vifname settings the domU starts just fine.

vif = [ '' ]

Same error when used wi classic Bridge for networking.

Is vifname setting still supported?

On CentOS5 & Xen 3.4 this parameter works just fine.
