+## Host
+### Networking for nested VMs
+To pass through the network connection to nested VMs, the first VM has to put the network adapter into promiscuous mode.  
+By default only root is allowed to do that, however the permissions can also be granted to others.  
+
+Grant permission to group:  
+```
+# chgpr (group) /dev/vmnetX
+# chmod g+rw /dev/vmnetX
+```
+
+Grant permission to everyone:  
+`# chmod a+rw /dev/vmnetX`  
+
+### Allow nested VMs
+Enable the following two settings under "Processor" in the settings of the VM.  
+`Virtualize Intel VT-x/EPT or AMD-V/RVI`  
+`Virtualize CPU performance counters`  
+
+### Fix MSRS bug on Ryzen CPUs
+Add `kvm.ignore_msrs=1` in `/etc/default/grub` to `GRUB_CMDLINE_LINUX_DEFAULT=`  
+Update the Grub configuration  
+`# grub-mkconfig -o /boot/grub/grub.cfg`
