vnf: support of vloop_vnf VM
Additional modifications are required to support vloop_vnf
as a master VM image for PVP and PVVP deployments.
Firewall is disabled directly by call of iptables to avoid
dependency on distribution specific firewall handling.
Default configuration values in 04_vnf.conf were set according
to vloop_vnf to make its usage easy. Values are generic
enough to work well also with other images.
Parameters VANILLA_NICx_NAME and vanilla_nicx_name were renamed
to GUEST_NICx_NAME and guest_nicx_name respectively, because
they are used for all vswitch versions. Functionality
of CLI options was fixed. Default values of GUEST_NICx_NAME
were changed to work with vloop_vnf image.
Bug with modification of TRAFFIC_DEFAULTS values has been fixed.
Deep copy is used and l2 and l3 dictionaries are correctly
updated to avoid issues.
Qemu disc emulation has been set to SCSI again to avoid
error messages related to non-functional DMA in syslog. Appropriate
kernel modules were added into vloop_vnf to support scsi
disk emulation during boot.
