Virtualisation tutorial by R Botha on 2024/11/08
1) QEMU/KVM setup
2) Folder / drive for data
3) Sharing folder for VM
4) Set up Virtual machine - Linux
5) Link VM to shared data on Host


1) QEMU/KVM SETUP
-----------------

sudo apt-get install virt-manager

#Add user access to QEMU-KVM

sudo usermod -a -G kvm roelf
sudo nano /usr/lib/libvirt/libvirt-guests.sh
#Edit shutdown to suspend or shutdown, depending on requirement, and on_boot to ignore / start
ON_BOOT="ignore"
ON_SHUTDOWN="suspend"

2) DATA DRIVE ON LINUX 
-----------------------
Install device, make sure the laptop boot is set up to be from OS drive


blkid 
#Get data drive UUID witk blkid / disks app
#add to /etc/fstab:
UUID=8b2182cc-c30c-48a9-8928-39acc303e5ce /Data ext4 defaults 0 0

sudo mkdir /Data
sudo mount /Data


Structure on /Data
    • Work - maybe linked to Work Google
    • Work-Confidential – LOCAL Only
    • Personal - maybe linked to personal email
    • TEMP   - To handle incoming data + sort into the other folders

User permissions - set the necessary with chown and chmod

Link in home folder:
roelf@roelfl5:~$ ln -s /Data/Work/ WORK
etc

Now you have the places to load all your data: Work, Personal, etc



3) SHARING DATA DRIVE / FOLDER FOR VM
-------------------------------------

#VM and SAMBA and sharing to Wi7 VM
sudo nano /etc/samba/smb.conf
#add to [global] section: 
    usershare owner only = yes
    interfaces = 127.0.0.0/8 192.168.122.0/24
    bind interfaces only = yes
[Data]   
Comment = Samba Shared Directory   
path = /Data   
writable = yes   
guest ok = yes   
read only = no
force user = roelf

sudo service smbd restart
sudo smbpasswd -a roelf     (make same password as for Windows VM user roelf)







4) SET UP VM 
------------

Linux:
------
Linuxmint xfce - Lightweight https://linuxmint.com/download.php 


Windows:
--------
Install Drivers for Windows:
https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/archive-virtio/ 
Link via CD drive

Make sure Virtio drivers are used for all storage and networking devices!
Change CD drive(s) to z:, y: etc



BOTH:
-----
HOST side:
Make sire the qemu-ga is connected when client OS is running
sudo virsh net-autostart default

Test suspend option / integration with cmd on host:
virsh list --all
virsh managedsave Win7_RoelfL5



5) Link VM to Shared Data Drive
-------------------------------
Browse for network drives on 192.168.122.1 - Link /Data to D: (Auto reconnect) or /Data (OS Dependent)
