Hi Swapnil,
I am posting the answer you received from Sean-K-CA:
From the screenshot it looks like you are getting an error attempting to connect from the vSphere client. That is generally used to connect to the vCenter or ESX server. Once logged in to vCenter or ESX, you can then open a console session to the VM. Otherwise, you would access the VM just as you would a standard system; RDP, SSH, etc. In this case it’s a *NIX based OS, so you would use SSH.
If you are having problems connecting to your vCenter or ESX, you’ll need to contact VMware for further assistance.
Please let us know if this helps.
Best regards,
Taylor
