Hi

I execute them using solidcp 

You can locate the function at Configuration > Servers > "Your Server" > Hyper-V

aha, 😀 I saw the variables when setting up the templates again, but I never bothered looking at the function, this is great, dang this makes things a lot more expandable.. Nice thank you for waking me up to this !!  👍 👍 

As an addition, most times issues is caused with vmq on some servers like dell with broadcom adapters, etc it is advised to disable vmqueue, even altaro reccomends disabling this on all vms.. sorts out slow responses on network.

Get-VMNetworkAdapter -VMName $vmName | Set-VMNetworkAdapter -MaximumBandwidth 10000000
Set-VMNetworkAdapter -VMName $vmName -VmqWeight 0

Use this to check the current statuses of the adapters on the vms

Get-VMNetworkAdapter -ComputerName PROLIANTDL380 -VMname * | Select VMName, VMQweight

Other option you can also do is if you want to manage the disk quality of Service, is to manage the iops on the drive, each iop is 8k so you can prevent them from abusing the disk access

Set-VMHardDiskDrive -VMName $vmName -MaximumIOPS 50

Specifies the maximum normalized I/O operations per second (IOPS) for the hard disk. Hyper-V calculates normalized IOPS as the total size of I/O per second divided by 8 KB.
