The beta community consensus is that VMware Workstation or Player often handles the Longhorn display drivers more easily than QEMU. The Longhorn builds contain an early implementation of LDDM (Longhorn Display Driver Model). In QEMU, you can attempt to install drivers via Device Manager, but many users report graphical glitches or DWM (Desktop Window Manager) crashes when using standard drivers.

Making work on qcow2 is an act of digital defiance. You are forcing a half-finished, 21-year-old operating system to run on a modern KVM hypervisor using a copy-on-write disk format that its developers never imagined. The "work" involves stripping away modernity: disabling HPET, forcing single CPU cores, using IDE instead of virtio, and accepting sub-10fps UI rendering. windows longhorn qcow2 work
Using with qcow2 (QEMU Copy On Write) virtual disks is the most reliable method for "making Longhorn work" today. It provides superior compatibility, hardware emulation control, and snapshot capabilities compared to modern hypervisors. Why Use QCOW2 for Longhorn?
The file-copying phase can be long. Do not interrupt it. 4. Post-Install and Troubleshooting Once installed, running the OS on qcow2 may reveal issues: The beta community consensus is that VMware Workstation

What of Longhorn are you trying to run?
You must freeze the hypervisor's RTC (Real-Time Clock) to a year matching your specific Longhorn build (usually between 2003 and 2005).
We want a raw-ish feel but with snapshot capabilities. Do not use raw. Do not use vmdk. Qcow2 is ideal because Longhorn will crash often. With qcow2, you can instantly roll back.
