As part of consolidating all common Python-based functionality into the new sonic-py-common package, this pull request: 1. Redirects all Python applications/scripts in sonic-buildimage repo which previously imported sonic_device_util or sonic_daemon_base to instead import sonic-py-common, which was added in https://github.com/Azure/sonic-buildimage/pull/5003 2. Replaces all calls to `sonic_device_util.get_platform_info()` to instead call `sonic_py_common.get_platform()` and removes any calls to `sonic_device_util.get_machine_info()` which are no longer necessary (i.e., those which were only used to pass the results to `sonic_device_util.get_platform_info()`. 3. Removes unused imports to the now-deprecated sonic-daemon-base package and sonic_device_util.py module This is the next step toward resolving https://github.com/Azure/sonic-buildimage/issues/4999 Also reverted my previous change in which device_info.get_platform() would first try obtaining the platform ID string from Config DB and fall back to gathering it from machine.conf upon failure because this function is called by sonic-cfggen before the data is in the DB, in which case, the db_connect() call will hang indefinitely, which was not the behavior I expected. As of now, the function will always reference machine.conf. |

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
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 #
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
```
