Extending the Guest VM hard disk
The
default disk size of the created instance is 175.8G. Follow these instructions
to extend the guest VM.
- Shut down a running
guest machine's virtual disk by entering its name or ID.
[localadmin@localhost network-scripts]$ sudo virsh list [sudo] password for localadmin: Id Name State ---------------------------------------------------- 1 EngPerf3-CL1-TN running 2 EngPerf3-NCN-TN running 9 vt800_128 running [localadmin@localhost network-scripts]$
[localadmin@localhost network-scripts]$ sudo virsh shutdown <instance-name> Domain vt800_128 is being shutdown [localadmin@localhost network-scripts]$
[localadmin@localhost network-scripts]$ sudo virsh list Id Name State ---------------------------------------------------- 2 EngPerf3-CL1-TN running 3 EngPerf3-NCN-TN running [localadmin@localhost network-scripts]$
- Locate the guest
image disk path.
[localadmin@localhost ~]$ sudo virsh domblklist vt800_128 Target Source ------------------------------------------------ hda /home/localadmin/Downloads/vt800_128v1_OS_7_0_0_0_0_GA_09132019_kvm_R8_2_0_1_0_GA_10172019.qcow2 [localadmin@localhost ~]$
- Extend the disk
size to the desired capacity by entering the following command.
[localadmin@localhost ~]$ sudo qemu-img resize /home/localadmin/Downloads/vt800_128v1_OS_7_0_0_0_0_GA_09132019_kvm_R8_2_0_1_0_GA_10172019.qcow2 +10G
Note:
quemu-img cannot resize an image that contains snapshots. You must first remove all VM snapshots:[localadmin@localhost ~]$ sudo virsh snapshot-list vt800_128 Name Creation Time State -------------------------------------------------- snapshot1 2019-04-16 08:54:24 +0300 shutoff
[localadmin@localhost ~]$ sudo virsh snapshot-delete --domain vt800_128 --snapshotname snapshot1 Domain snapshot snapshot1 deleted
- Extend the disk by
using
+ before disk
capacity
[localadmin@localhost ~]$ sudo qemu-img resize /home/localadmin/Downloads/vt800_128v1_OS_7_0_0_0_0_GA_09132019_kvm_R8_2_0_1_0_GA_10172019.qcow2 +10G Image resized. [localadmin@localhost ~]$
- Power up the guest
machine
[localadmin@localhost ~]$ sudo virsh start vt800_128 Domain vt800_128 started [localadmin@localhost ~]$
- Verify the disk
layout
