- In this video tutorial, we will cover how to install KVM (Kernel-based Virtual Machine) on Ubuntu 24.04 LTS system and demonstrate creating a virtual machine using the virt-manager application.
########## KVM Installation Steps on Ubuntu 24.04 ##############
1) Package Apt Repository Packages Index
sudo apt update
2) Check if Virtualization is enabled
egrep -c '(vmx|svm)' /proc/cpuinfo
Install the cpu-checker package
sudo apt install -y cpu-checker
Another way to check if KVM virtualization is enabled
kvm-ok
3) Install KVM on Ubuntu 24.04
sudo apt install -y qemu-kvm virt-manager libvirt-daemon-system virtinst libvirt-clients bridge-utils
4) Enable and start virtualization daemon
sudo systemctl enable --now libvirtd
sudo systemctl start libvirtd
Check virtualization daemon is running
sudo systemctl status libvirtd
5) Add Your Local User to the KVM and Libvirt Group
sudo usermod -aG kvm $USER
sudo usermod -aG libvirt $USER
6) Create Network Bridge using netplan
Create a file with following content
sudo vi /etc/netplan/01-netcfg.yaml
network:
version: 2
renderer: NetworkManager
ethernets:
ens33:
dhcp4: false
dhcp6: false
bridges:
br0:
interfaces: [ens33]
dhcp4: false
addresses: [192.168.2.120/24]
routes:
- to: default
via: 192.168.2.1
metric: 100
nameservers:
addresses: [8.8.8.8]
save and close the file.
sudo chmod 600 /etc/netplan/*.yaml
Now, run following command to apply above network changes
sudo netplan apply
7) Launch KVM Virt-Manager and Create Virtual Machines

Man you're saviour 😊😊😊 really thanka for your sharing your knowledge. I have been struggling for years 😮😮😮 for this really appreciate
Glad it helped
The tutorial was excellent but I ended up having a problem when I tried to ping the ip address of the guest machine from the host machine. Ping came as "4 packets transmitted, 0 received, 100% packet loss, time 3073ms".Have no idea how to fix problem. Your explainations were great and easy to understand.
Thank you for very nice tutorial. What if I want to install macOS Sonoma instead?
hi, thank you for sharing how to configure kvm! I am using a laptop with wireless card only, no ethernet card could you show how to configure the bridge for computers with wireless only?
the only problem i had is it doesn't show [ens33] in IP addr instead of it there is enp2s0
apsolutly not able to install on 24.04.1 - it always says if i want to create a new VM "Error:No active Connection for this Installation" - so whats wrong.
noticed this message shows only if i open virt-manager using gui...always have to run sudo virt-manager from terminal for it to work right.
I don't think "apt update" installs the updates @1:37 , think you need to run 'apt upgrade' to actually update the binaries. now the prompt is left at "can be upgraded" .. not "have been upgraded". Lovely tone in your video, nice work. Actually i am wrong in the above... but it is good to run the upgrade command right after install.
hi~
i followed everything in this video , and at first it seems everything is working fine but after a few mins. i no longer have internet connection , can you me help me with this one .
Hi,
It appears like a network issue, please cross verify the network configuration like IP address, Gateway and DNS IP. Try to ping your gateway IP address and then DNS Server IP. If both are reachable then you should access internet otherwise check your underlay network.
Hi at minute 8:27 of your video the lower part of the terminal says "Lines 1-22/22 (END) message which blocks my terminal and I am unable to remove it. Can you please tell me how you got rid of it to continue, as I am unable to proceed from there. thanks
You can use ctlr+c to get rid of of that situation.
how to enable virtualization in ubuntu 24.04? like I tried the rebooting one but it didn't worked
When you enable VT Technology from Bios Settings then virtualization will be enabled automatically in Ubuntu OS.
nice .. can you install opnsense with this method ?
I just did this with the help of your guide last night. Instead of using a HDD image file i had a free SSD in my pc which i want to give to VM. I saw that it can be done by providing /dev/-devicename- in the vm device setup. And it works, and should be faster. However sometimes index name of that device changes after reboot. For example nvme1n1 become 2n1 or something stupid like that.
Is there anything i can do to prevent this, because then my VM will not boot, since it is looking for a disk under the previous name.
Method 1: Use UUID (Universally Unique Identifier)
Find the UUID or Label of the SSD:
You can use the blkid command to find the UUID and label of your SSD.
sudo blkid
This will output something like:
/dev/nvme1n1: UUID="abcd-1234" TYPE="ext4" PARTUUID="12345678-01"
Note down the UUID (e.g., abcd-1234) or the label if it has one. Use the disk by its UUID like /dev/disk/by-uuid/abcd-1234
When setting up the VM device in your virtualization software (VirtualBox), use the /dev/disk/by-uuid/ syntax instead of the device name.
Method 2: Create a Udev Rule for Persistent Symlink:
Create a new udev rule file, for example /etc/udev/rules.d/99-persistent-ssd.rules:
sudo nano /etc/udev/rules.d/99-persistent-ssd.rules
Add the following rule, replacing UUID with the actual UUID of your SSD:
KERNEL=="nvme*", SUBSYSTEM=="block", ENV{ID_FS_UUID}=="abcd-1234", SYMLINK+="my_ssd"
Reload Udev Rules and Trigger:
Reload the udev rules and trigger them:
sudo udevadm control --reload-rules
sudo udevadm trigger
Use the Symlink in VM Configuration:
Now, you can use /dev/my_ssd in your VM configuration instead of /dev/nvme1n1.
@@linuxtechi9979 Thank you, that is great. I will try it out. I would like to have reliable virtual windows 10 for few apps that i need for work, like solidworks, and some engineering simulation software, and rendering software. I am curious to compare cinebench score from native rendering to VM rendering. So i am working on understanding how to pass through different hardware, like nvidia gpu, usb devices and to really speed up the virtual machine since from time to time it feels quite slow, the lag is noticable even thou i provide a lot of resources. Sad truth is that due to professional software many of us cannot completely delete windows, but if we could just turn on a VM whenever we must we can get free from microsoft and their aggressive forced updates, driver reinstalls, defaulting settings, and ofcourse spyware.
