Dear friends,

I faced the same issue and posted a question in here but to no avail. I initially installed version 6.1-7 later upgraded to version 6.2-6. I found a workaround to this issue with a little trial and error session.

My finding;

1st situation - able to clone the source VM successfully while the VM is in running state, otherwise I get an error message like this "VM 100 qmp command failed - VM 100 not running"

2nd situation - able to clone the source VM successfully while the VM is in the stopped state, to do this I had left the "Qemu Agent" checkbox unticked under the "System" tab when I spun new VM.
