-====== 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.
