Hello Team,

I have set the CPU throttling to 1% on GUI, however it seems the value has not reflected in v2v-import file on conversion host or appliance. Please let me know if we need any additional steps to set the throttling.  Please find attached snapshot.

The top command for "qemu-img convert" process showing the CPU utilization varies and goes beyond 1% threshold. So please have a look.
