Improve VM deploy performance in SCVMM

SCVMM use BITS over https to deploy virtual machine to host server. To improve the performance of virtual machine deploy, you can disable encrypted file transfers for Host Group.

  1. Open Virtual Machine Manager Administrator Console (aka SCVMM Console) on the Application Tier and connect to VMM Server
  2. Click Host on the left side pane.
  3. Right Click on All Host node, and select Properties.
  4. Select the check-box “Allow unencrypted file transfers”

Note: if you use library server, you should set Allow unencrypted file transfers for every library servers.


The same can be done in following SCVMM PowerShell command

Set-VMHostGroup -VMHostGroup “All Hosts” -AllowUnencryptedTransfers $true
