+====== Issues & Solutions ======
+===== Windows 10 =====
+==== GPU code 43 ====
+Reinstall uninstall and reinstall GPU drivers
+==== VM S3 (suspend/sleep) not available ====
+Install ''qxldod'' drivers.
+==== Slow suspend ====
+Disable hibernation: ''powercfg /h off''
+==== My IO is too slow ====
+[[https://www.nikhef.nl/~dennisvd/lvmcrap.html|Delet LVM snapshots...]]
+==== ''virsh dompm{suspend,wakeup}'' does not... ====
+Install ''qemu agent'' and ''vioserial'' driver in guest
+==== VM crashes when idle for some time ====
+Well, disable screen blanking and autosuspend...
+==== Audio on PulseAudio ====
+[[https://wiki.archlinux.org/index.php/libvirt#PulseAudio]]
+  <domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>
+   [...]
+   <qemu:commandline>
+     <qemu:env name='QEMU_AUDIO_DRV' value='pa'/>
+     <qemu:env name='QEMU_PA_SERVER' value='sound.waw.hackerspace.pl'/>
+   </qemu:commandline>
+  </domain>
+==== Audio stutters ====
+Change ''Default Format'' from ''16bit 48kHz'' to ''16bit 44.1kHz'' in emulated sound card properties in guest.
+==== Shitty IO performance vol. 2 ====
+[[https://forums.servethehome.com/index.php?threads/performance-of-kvm-qemu-disks-on-zfs-volumes.12550/#post-119801]]
+==== Everything's shit ====
+Enable "HIGH PERFRORMANCE" power profile.
+==== GPU crashes after host resume ====
+Seems like keeping QXL enabled on VMs with Radeon GPU passed through fixes GPU crashes on host suspend. (VM needs to be suspended first as well)
+==== QXL/Spice display does not automatically resize to client window ====
+Install spice guest tools:
+https://www.spice-space.org/download/windows/spice-guest-tools/spice-guest-tools-latest.exe (https://www.spice-space.org/download.html)
+===== FreeBSD =====
+==== 11.1 ====
+=== Hypervisor configuration ===
+  * Network: choose bridged. Bridge name: ''br0''.
+=== Hypervisor bug ===
+There's a problem with the ''Opteron_G5'' hypervisor, which is set by default.
+The solution is to replace ''Opteron_G5'' with ''kvm64'' or ''Opteron_G3''.
+Also, there is an open bug report for this issue on [[ https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=213333 | FreeBSD Bugzilla ]].
+Fixed in 12.0.
+===== Linux Guests with PCIe Passthrough =====
+Use UEFI & Q35 platform model. (re https://forum.level1techs.com/t/fedora-28-pci-e-gpu-passthrough-linux-guest/127161/3)
+===== MacOS =====
+https://github.com/kholia/OSX-KVM + ''wieloryb:/storage/common/S*/O*/*.README''
+Works perfectly fine, including GPU passthrough.
