Tuning Virtual Processor Manager (VPM)

Oracle recommends that you use the vpm_xvcpus command to tune virtual processor.

When you enable CPU folding with only one CUP, your system may reboot and face performance problems.

Check if CPU folding is enabled:
```
schedo -L| grep "vpm_xvcpus" |cut -d " " -f 17
```
The above command returns 0 if CPU folding is enabled.
Set value of the vpm_xvcpus parameter to at least 2:
```
schedo -o vpm_xvcpus=2
```
