Procedure

Get-VMResourceConfiguration -VM VM1
Get-VMResourceConfiguration -VM VM1 | Format-Custom -Property DiskResourceConfiguration
Get-VM VM1 | Get-VMResourceConfiguration | Set-VMResourceConfiguration -MemSharesLevel low
Get-VM VM1 | Get-VMResourceConfiguration | Set-VMResourceConfiguration -CpuSharesLevel high
$vm1 = Get-VM VM1
$vm1disk = Get-HardDisk $vm1
Get-VMResourceConfiguration $vm1 | Set-VMResourceConfiguration -Disk $vm1disk -DiskSharesLevel custom -NumDiskShares 100

1	View the resource configuration for the `VM1` virtual machine. Get-VMResourceConfiguration -VM VM1
2	View the disk share of the `VM1` virtual machine. Get-VMResourceConfiguration -VM VM1 \| Format-Custom -Property DiskResourceConfiguration
3	Change the memory share of the `VM1` virtual machine to low. Get-VM VM1 \| Get-VMResourceConfiguration \| Set-VMResourceConfiguration -MemSharesLevel low
4	Change the CPU shares of the `VM1` virtual machine to high. Get-VM VM1 \| Get-VMResourceConfiguration \| Set-VMResourceConfiguration -CpuSharesLevel high
5	Change the disk share of the `VM1` virtual machine to 100. $vm1 = Get-VM VM1 $vm1disk = Get-HardDisk $vm1 Get-VMResourceConfiguration $vm1 \| Set-VMResourceConfiguration -Disk $vm1disk -DiskSharesLevel custom -NumDiskShares 100
