why linux remote command or bash script does not return correct output?

I am facing issue while executing a remote command. If I execute command by logging into remote machine, it works. But if I execute same command from my laptop to remote machine it returns different status code. 

Local execution on 192.168.0.166:  
root@monica-E470:~# virsh list --state-shutoff | grep Qcow2 | wc -l
1

Remote Command execution: 
root@sandipd-ThinkPad-E450:~# ssh [email protected] 'virsh list --state-shutoff | grep Qcow2 | wc -l'
[email protected]'s password: 
0

I have tried with different scenarios, but no luck. Has anyone faced same issue?

You have to add a pseudo terminal to execute complex commands in a remote server. Try this instead:

ssh -t [email protected] 'virsh list --state-shutoff | grep Qcow2 | wc -l'

Refer man page of ssh for more info.
