FINALLY got #QEMU performance up today! getting wonderful performance in-game and it's super nice
turns out i was missing some so-called "hyper-v enlightenments", which are some paravirtualization stuff that's also implemented in the KVM. these allow windows guests to run a LOT faster (and also apparently other guests too that support the flags)
the flags in question are hv_relaxed, hv_vapic, hv_spinlocks and hv_time. i'm not totally sure what each one does or how they work yet, but are a *must have* running windows guests. libvirt supports these once you put them into the XML for your guest and hooh boy does it make a world of difference.
Mastodon instance for devices part of the devfs virtual filesystem. And friends.
