I am using Ubuntu Server 12.04.04 LTS that I have migrated from VMWare ESXi to Hyper-V. Microsoft has supplied the Linux community with Linux Integration Components (LIC) that provide additional support for Ubuntu Linux.
Integration services are built in modules that need to be added to startup. To add them edit the modules file:
vi /etc/initramfs-tools/modules
append the following modules to the file:
hv_vmbus
hv_storvsc
hv_blkvsc
hv_netvsc
Now, update initramfs:
sudo update-initramfs –u
and now reboot.
Upon reboot, you should see the modules with lsmod.
