====== mitigations ======

I've noticed that switching from ''kvm64'' CPU to ''x86-64-v2-AES'' or ''host'' slows down Windows guest insanely.

Mitigations can be disabled in Windows guest using this tool:

Or:
<code powershell>
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v FeatureSettingsOverride /t REG_DWORD /d 3 /f
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v FeatureSettingsOverrideMask /t REG_DWORD /d 3 /f
