Master VM High Booting Time

[adriani001]

Hi,

I have implemented VDI using Horizon. I am using ESXi 6.7 U2,Horizon Connection 7.8, Agent 7.8, VMware Tools 10.3.5 and as a master image Windows 10 version 1903.

I am facing a high booting time of master image VM, also the Virtual Desktops. I haven't used any VMware OS Optimization Tool until now.

Any suggestion what to do about this issue?

Are you using VMFS 6 datastores? If so, there is known issue with W10 1809/1903 and snapshots which has now been resolved with vSphere 6.5 Update 3 but not with vSphere 6.7 as yet.

windows 10 1809 slow

One workaround at present for vSphere 6.7 is to use VMFS 5 datastores until the update for vSphere 6.7 is available.

Thank you for your reply. I am using vSphere 6.7 and VMFS 6.

I just moved the VM to VMFS 5 Datastore and it is ok now, they have a normal booting time.

Or you could clone it instead of making snapshots.  Only makes sense if you have a good deduping SAN unit though, but at least you don't have to have and vmfs 5 luns.
