Ubuntu 20.04 LTS Üzerine Hyper-V İçin linux-vm-tools Kurulumu

Hyper-V üzerinde sanallaştırma yaparak linux makina ayağa kaldırdıysanız desktopda oldukça kötü performans veriyor, çünkü rdp üzerinden değilde sanki KVM‘miş gibi çalışıyor haliyle gecikme oluyor ciddi anlamda tepkiler kötüleşiyor. Bunun için sistemde linux-vm-tools ve xrdp paketleri kurulu olmalı üstüne birde düzgün ayarlanmış olmalı.

Hala 20.04 LTS sürümüne aşağıdaki XRDP ayarlaması geçilmemiş. Düzenlenmiş olan betiği şöyle bırakıyorum.

#!/bin/bash

#
# This script is for Ubuntu 20.04 Focal Fossa to download and install XRDP+XORGXRDP via
# source.

# Major thanks to: http://c-nergy.be/blog/?p=11336 for the tips.

Git üzerinden kurmak isteyenler için ise gereken komutların tamamını şöyle bırakıyorum.

sudo apt install git
git clone https://github.com/microsoft/linux-vm-tools.git
cd linux-vm-tools
git fetch --all
git pull origin pull/106/head:pull_106
git checkout pull_106
cd ubuntu/20.04/
sudo bash ./install.sh

Ayrıca bir takım iyileştirmeler için azure’da kullanılan ubuntu kernellerini indirip sisteminize dahil edebilirsiniz.
