Linux – Hyper-V not Launching Ubuntu 17.10.1

This is conceptual, not step by step, but it should explain enough to help you figure out what you need to do. The Hyper-V switch that the VM uses needs to be either External or Internal and not Private. Keep in mind that an External switch will look like a LAN connection to the VM, not a wireless connection even if on the real hardware it is associated with a wireless adapter. Also, an External switch may not work with all wireless routers as some recognise that a DHCP request coming from your VM is really coming from the same machine and won't give it an address.

The way around this (the wireless router sounds like the issue from your description) is to set the Hyper-V switch for your VM to be Internal and then use ICS (Internet Connection Sharing) on the hardware's real wireless adapter, sharing with the Hyper-V switch. ICS is on a tab when you open the properties on the adapter that just says "Sharing". It makes your adapter behave like it is a NAT router to the other adapters in your machine. It responds to the VM's DHCP request and allows the VM to connect to it so to speak.

I found an info in the French Ubuntu forums from other user who has Ubuntu freezes: It may be caused by "dynamic tick".

Their solution:

cd /etc/default
sudo vi grub

add nohz=true in parameters of the line GRUB_CMDLINE_LINUX_DEFAULT. Then do a

sudo grub-update
