Once we understand what is requirement we could resize disk like below.
Image: /data/vm_images/geekpills_wordpress/system.img decreasing could dangerous in case Disk consumption is more what you trying to qemu-img info /data/vm_images/geekpills_wordpress/system.img
#Qemu img resize how to#
Then we could check Disk size and can analyse how much we need to increase, as per my requirement I need to increase(I suggest not to decrease disk size, if you don’t know much about qcow2 format and how to troubleshoot these cases). Hda /data/vm_images/geekpills_wordpress/system.img To know disk used in this Vitual Machine, we could use virsh domblklist command like virsh domblklist gpw Once your machine is in shutoff state as of mine in below output, we can start resize virsh list -all| grep gpw otherwise you can also shutodown or destroy virtual Machine through virsh command as well. QEMU emulator version 2.11.1(Debian 1:2.11+dfsg-1ubuntu7.4)Ĭopyright (c) 2003-2017 Fabrice Bellard and the QEMU Project developersįor this first we have to shutdown Virtual Machine, its always good to poweroff virtual machine from login prompt. So mentioning what Host machine used for this lsb_release -dĭescription: Ubuntu 18.04 uname kvm -version We can use any Guest KVM virtual machine for this setup. In this case, we are going to ShutDown virtual machine, while resizing Disk used in KVM virtual machine. In in this post we will see How to resize qcow2 disks image used in KVM virtual images, Actually situation is like that, Today I clone one of my base image which i need to work on, But further working on same I need to resize its Disk size.
