This a short blog about some issue i had after migrating from old DaaS 6 , to daas 8. with the Fling Daas migration tool https://labs.vmware.com/flings/horizon-daas-migration-tool

After the migration with blast and pcoip i only got a black screen and no error. No login error but only a black screen.

After some troubleshooting and checking the advanced settings. I noticed a missing paramater. After setting this parameter in the Advanced setting of the VM, i could login without problems.

Do the following. Power off the VM go to settings –> VM Options –> Advanced –> Edit Configuration and set svga.enableScreenDMA TRUE , Power on the VM, and there should be no more black screen.

You can do more VDI’s , with some powershell

$vdi = Get-VM VDIname*

foreach ($vm in $vdi) {
New-AdvancedSetting -Entity $vm -Name svga.enableScreenDMA -Value TRUE -Force -Confirm:$FALSE
