Recently I needed to quickly set up fresh new VM with Ubuntu 18.04 TLS under Hyper-V (this is not my ordinarily toolbox but I can not use anything that Hyper-V this time).
Ok, I did the install (I used to choose ‘hwe’ install during the initial setup menu) and while try to find a way to use Hyper-V integration I found I need to do this magic:
echo 'hv_vmbus' >> /etc/initramfs-tools/modules echo 'hv_storvsc' >> /etc/initramfs-tools/modules echo 'hv_blkvsc' >> /etc/initramfs-tools/modules echo 'hv_netvsc' >> /etc/initramfs-tools/modules apt -y install linux-virtual linux-cloud-tools-virtual linux-tools-virtual update-initramfs -uOk, I did that and everything is ok, but how to find out which kernel and packages I need not to keep and which can I remove for good? You see, now I have plenty of kernel packages and I understand I don’t need most of them:
