Added vmhost paramater in dev.facts

[dineshbaburam91]

Added vmhost parameter in the facts template to check running device is vmhost supported or not.



If vmhost returns True, then the running device is Vmhost supported device.
If vmhost returns False, then the running device is non-Vmhost-supported device and Junos evolved device.
If Vmhost returns None, in case of error to fetch the vmhost data.

Functional test cases:



from jnpr.junos import Device
dev_vmhost = Device(host=‘x.x.x.x’, user='root', password=‘’xxxx)
dev_evolved = Device(host='x.x.x.x’', user='root', password=‘xxxx’)
dev_non_vmhost = Device(host='x.x.x.x’', user='root', password=‘xxxx’)

dev_vmhost.open()
dev_evolved.open()
dev_non_vmhost.open()

print("The output of facts['vmhost'] in vmhost supported device: " + str(dev_vmhost.facts['vmhost']))
dev_vmhost.facts_refresh()
print("The output of facts['vmhost'] in vmhost supported device after refresh: " + str(dev_vmhost.facts['vmhost']))

print("The output of facts['vmhost'] in junos evolved device:  " + str(dev_evolved.facts['vmhost']))
dev_evolved.facts_refresh()
print("The output of facts['vmhost'] in junos evolved device after refresh:  " + str(dev_evolved.facts['vmhost']))

print("The output of facts['vmhost'] in non vmhost supported device: " + str(dev_non_vmhost.facts['vmhost']))
dev_non_vmhost.facts_refresh()
print("The output of facts['vmhost'] in non vmhost supported device after refresh: " + str(dev_non_vmhost.facts['vmhost']))

O/p:


The output of facts['vmhost'] in vmhost supported device: True
The output of facts['vmhost'] in vmhost supported device after refresh: True
The output of facts['vmhost'] in junos evolved device: False
The output of facts['vmhost'] in junos evolved device after refresh: False
The output of facts['vmhost'] in non vmhost supported device: False
The output of facts['vmhost'] in non vmhost supported device after refresh: False
