Keep custom rsyslog file for docker-sonic-vs (#13056) 
docker-sonic-vs doesn't have the infra needed for the syslog rate limit
configuration, so it's not going to be rendering jinja templates to
overwrite /etc/rsyslog.conf. This also means that syslog messages would
get logged twice (because both the default /etc/rsyslog.conf file and
/etc/rsyslog.d/50-default.conf are telling it to log to syslog).

Therefore, keep the custom static /etc/rsyslog.conf file for docker-sonic-vs.

Fixes sonic-net/sonic-swss#2570.

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
