VM WINDOWS SERVER 2025 SLOW

[_matheus.honorato]

Hi guys, how are you?

I'm with a problem in my VM Proxmox, where i have a installation with Windows Server 2025 showing slowness.
This is my configs.

This VM has only a power-automate process from Microsoft running.

Do you not have the virtio drivers installed on the guest?
Also, what CPU type is assigned to the VM? There has been discussion about not using `host` with a windows guest.

I have never felt slow in a virtual machine configured this way.

I am using the 2025 evaluation ISO and have no issues with RDS with the following options

args: -cpu host,hv_passthrough,level=30,-hypervisor,+vmx
cpu: host

I don't have it, I'll install it and change the network. I'll install the agent too.
