![]() ![]() To extend your OS partition, refer to below guides. My VM total disk capacity is now 40GB, previously it was 30GB. Last login: Fri Apr 19 06:11:19 2019 from your new disk layout. SSH to your VM and become the root or using an user account that has sudo rights. Now power up the VM # virsh start webserver I/O size (minimum/optimal): 512 bytes / 512 bytes Step 4: Grow VM partition Sector size (logical/physical): 512 bytes / 512 bytes Note: The disk size inside the virtual machine still has to be resized, now still 30G # qemu-img info /var/lib/libvirt/images/webserver-2.qcow2Ĭonfirm disk size with fdisk command. $ qemu-img resize /var/lib/libvirt/images/rhel8.qcow2 +10GĬheck the new virtual disk size 40G. ![]() img has been extended) When I flash an SD card with this img I get a kernel panic. Then extend the disk by using the ` +‘ before disk capacity. fdisk -raspbian-stretch-lite.img delete the old partition and create a new partition from the start of the original partition to the end (the end is now longer because the. # virsh snapshot-delete -domain webserver -snapshotname snapshot1 See this example: # virsh snapshot-list webserver You will need to first remove all VM snapshots. Please note that qemu-img can’t resize an image which has snapshots. # qemu-img resize /var/lib/libvirt/images/webserver-2.qcow2 +10G Since we know the location of our Virtual Machine disk, let’s extend it to our desired capacity. Image: /var/lib/libvirt/images/webserver-2.qcow2Ĭorrupt: false Step 3: Extend guest VM disk # qemu-img info /var/lib/libvirt/images/webserver-2.qcow2 My VM disk is located in ‘/ var/lib/libvirt/images/rhel8.qcow2‘. Except for migrating virtual disk, you can also migrate the whole virtual machine to reduce failures during migration and boot VM faster. You can obtain the same information from the Virtual Machine Manager GUI. Vda /var/lib/libvirt/images/webserver-2.qcow2 # virsh shutdown webserverĬonfirm that it is truly down before proceeding to manage its disks. If your guest machine is in running state, power it off using its ID or Name. Step 1: Shut down the Virtual Machine on KVMīefore you can extend your guest machine Virtual disk, you need to first shut it down. sudo virsh shutdown rhel8 Domain rhel8 is being shutdown. sudo virsh list Id Name State - 4 rhel8 running.

KVM uses QEMU which supports several image types, among them raw, cow, qcow, qcow2, vmdk, vdi among others available. Sometimes I need to extend or add disk space to my running VM (guest) to satisfy growing software requirements. ![]()
