@jelle also suggested that "since tools/kvm/kvm_stat/kvm_stat.service exists so no reason this service can't live upstream." Others have run into the same issue.

1. A new service for usr/bin/hv_fcopy_uio_daemon should be shipped now instead.
2. The wiki needs updating.
3. Current MS docs on the topic are outdated.

Additional info:

• package version(s): extra/hyperv 6.10-2 (linux-tools)
• link to report, if any: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/tools/hv/Makefile?id=82b0945ce2c2d636d5e893ad50210875c929f257

Steps to reproduce:

Install Arch linux under a Hyper-V vm with the hyperv package and even after reboot integrations services are missing.
