#QEMU IMG CREATE INSTALL#

Go ahead and install windows till the end. Once that you are connected windows installation should be up and ready to be installed as you can see below: Now the fun begins! run the script that we have created (“windows_10.sh”) and connect to the machine using a vnc client. Please note that this number is usually added up to 5900 which means that to connect to this machine we should connect to the vnc port 5900 + 0 = 5900. vnc :0: The port which will be used to connect to the machine using a vnc client.

#QEMU IMG CREATE ISO#

cdrom: Specifies the iso file that will show up as a cdrom in the Qemu machine. (note that this is the image we created earlier) drive: Specifies the image that will be used when running the machine. enable-kvm: Enables the use of kvm by qemu, a kernel API for boosting Qemu performance. cpu host: The qemu will use the cpu host to run qemu commands. m 4G : The machine will have 4GB of memory.

#QEMU IMG CREATE FREE#

Qemu-system-x86_64: Refers to the Qemu binary, feel free to use your own compiled binary. Save the file and make it executable using the command “chmod”. Open it using your favorite editor and insert the following: #!/bin/bash

#QEMU IMG CREATE WINDOWS 10#

Now we are going to create a script to run the machine with empty image “windows_10_圆4.qcow2” and the windows 10 installation iso.Ĭreate a new file called “windows_10.sh” and place it in “virtualization/qemu-scripts”. Move windows 10 iso to “virtualization/images” Move the image “windows_10_圆4.qcow2” to “virtualization/images”. Now you should have a file that is called windows_10_圆4.qcow2. windows_10_圆4.qcow2 specifies the image name and 500G is the image size in GB. Qemu support many different extensions for image files, you can find more info about that here. Run the following command: qemu-img create -f qcow2 windows_10_圆4.qcow2 500Gįirst we use the “qemu-img” binary provided with the Qemu package, the -f flag specifies the format of the image. Lets create a comfortable working environment:Ĭreate a working directory called “virtualization”, then create two sub-foldersįirst we are going to create an empty image that we are going to use later to install windows 10 on it.

vnc client to connect to QEMU monitor remotely.

So without any further introduction let’s get to work. That's it.Today we are going to create an empty image using Qemu and then we are going to install Windows 10 on it. Or for the ext4 disk: /dev/vdb1 /mnt/new-disk ext4 defaults 0 0 Or mount the partition: mkdir /mnt/new-diskĪdd to /etc/fstab for reboot persistence: /dev/vdb1 swap swap defaults 0 0 Or format it as ext4: mkfs.ext4 /dev/vdb1 For our example we use filesystem type 82įormat the disk as swap: mkswap /dev/vdb1 Reboot it so that the kernel sees the new disk: reboot Formatting the diskĮxecute these steps in your virtual machine. Note that if you already have a /dev/vdb disk you need to change vdb to aįree device like vdc or vdd. persistent option updates the domain xml file with an element for the newly Swap as a virtio ( /dev/vdb) disk to the domain (vm) example-vm. We use virsh to attach the disk image /var/lib/libvirt/images/example-vm. We use qemu-img to create a new raw disk image with a size of 1 GB.Īttach the disk to the example virtual machine using virsh: virsh attach-disk example-vm -source /var/lib/libvirt/images/example-vm-swap.img -target vdb -persistent Create and attach the disk imageĮxecute these steps on the KVM hypervisor host.Ĭd to the folder where you store your disk images: cd /var/lib/libvirt/images/Ĭreate the new disk image: qemu-img create -f raw example-vm-swap.img 1G The example vm is named example-vm in virsh (domain). The KVM hypervisor uses virsh for management. This was tested on a KVM hypervisor host running Ubuntu 12.04 LTS and a Ubuntuġ3.10 virtual machine.
