HOWTO Use Virtual Switch (VM)
- Install libvirt, kvm, qemu
sudo apt-get install libvirt-clients qemu-kvm libvirt-bin
- 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 #
- Create SONiC VM for multi-ASIC HWSKU Update sonic_multiasic.xml with the external interfaces required for HWSKU.
$ sudo virsh

Once booted up, create a file "asic.conf" with the content:
NUM_ASIC=<Number of asics>
under /usr/share/sonic/device/x86_64-kvm_x86_64-r0/
Also, create a "topology.sh" file which will simulate the internal
asic connectivity of the hardware under
/usr/share/sonic/device/x86_64-kvm_x86_64-r0/<HWSKU>
The HWSKU directory will have the required files like port_config.ini
for each ASIC.
Having done this, a new service "topology.service" will be started
during bootup which will invoke topology.sh script.
3. Access virtual switch:
1. Connect SONiC VM via console
```
$ telnet 127.0.0.1 7000
```
OR
2. Connect SONiC VM via SSH
1. Connect via console (see 3.1 above)
2. Request a new DHCP address
```
sudo dhclient -v
```
3. Connect via SSH
```
$ ssh -p 3040 admin@127.0.0.1
```
