Add python3 virtual environment for docker-ptf (#10599) 
Why I did it
Migrate ptftests script to python3, in order to do an incremental migration, add python virtual environment firstly, install all required python packages in virtual env as well.
Then migrate ptftests scripts from python2 to python3 one by one avoid impacting non-changed scripts.

How I did it
Add python3 virtual environment for docker-ptf.
Add submodule ptf-py3 and install patched ptf 0.9.3 into virtual environment as well, two ptf issues were reported here:
p4lang/ptf#173
p4lang/ptf#174

HOWTO Use Virtual Switch (VM)

  1. Install libvirt, kvm, qemu
sudo apt-get install libvirt-clients qemu-kvm libvirt-bin
  1. Create SONiC VM for single ASIC HWSKU
$ sudo virsh
Welcome to virsh, the virtualization interactive terminal.

Type:  'help' for help with commands
       'quit' to quit

virsh # 
virsh # create sonic.xml
Domain sonic created from sonic.xml

virsh #
  1. Create SONiC VM for multi-ASIC HWSKU
  • Based on the number of asics of hwsku, update device/x86_64-kvm_x86_64-r0/asic.conf
NUM_ASIC=<n>
DEV_ID_ASIC_0=0
DEV_ID_ASIC_1=1
DEV_ID_ASIC_2=2
DEV_ID_ASIC_3=3
..
DEV_ID_ASIC_<n-1>=<n-1>

For example, a four asic VS asic.conf will be:

NUM_ASIC=4
DEV_ID_ASIC_0=0
DEV_ID_ASIC_1=1
DEV_ID_ASIC_2=2
DEV_ID_ASIC_3=3

  • Create a topology.sh script which will create the internal asic topology for the specific hwsku. For example, for msft_multi_asic_vs: https://github.com/Azure/sonic-buildimage/blob/master/device/virtual/x86_64-kvm_x86_64-r0/msft_multi_asic_vs/topology.sh

  • With the updated asic.conf and topology.sh, build sonic-vs.img which can be used to bring up multi-asic virtual switch.

  • Update platform/vs/sonic_multiasic.xml with higher memory and vcpu as required.

    • For 4-asic vs platform msft_four_asic_vs hwsku, 8GB memory and 10vCPUs.
    • For 7-ASIC vs platform msft_multi_asic_vs hwsku, 8GB and 16vCPUs.

  • Update the number of front-panel interfaces in sonic_multliasic.xml

    • For 4-ASIC vs platform, 8 front panel interfaces.
    • For 6-ASIC vs platform, 64 front panel interfaces.

  • With multi-asic sonic_vs.img and sonic_multiasic.xml file, bring up multi-asic vs as:

$ sudo virsh
Welcome to virsh, the virtualization interactive terminal.

Type:  'help' for help with commands
       'quit' to quit

virsh #
virsh # create sonic_multiasic.xml 
Domain sonic created from sonic.xml

virsh #

  • Steps to convert a prebuilt single asic sonic-vs.img:

    • Use the updated sonic_multiasic.xml file and bring up virtual switch.
    • Update /usr/share/sonic/device/x86_64-kvm_x86_64-r0/asic.conf as above.
    • Add topology.sh in /usr/share/sonic/device/x86_64-kvm_x86_64-r0/
    • stop database service and remove database docker, so that when vs is rebooted, database_global.json is created with the right namespaces.
      • systemctl stop database
      • docker rm database
    • sudo reboot
    • Once rebooted, VS should be multi-asic VS.

  • Start topology service.

sudo systemctl start topology.
  • Load configuration using minigraph or config_dbs.

  1. Access virtual switch:

    1. Connect SONiC VM via console
    $ telnet 127.0.0.1 7000

    OR

    1. Connect SONiC VM via SSH

      1. Connect via console (see 3.1 above)

      2. Request a new DHCP address

      sudo dhclient -v
      1. Connect via SSH
      $ ssh -p 3040 admin@127.0.0.1
