New page

{{Admon/important | This is a work in progress}}

=== Adding memory to a VM ===

Shutdown the VM

sudo virsh shutdown "name_of_vm"

Edit the configuration of the VM

sudo virsh edit "name_of_vm"

...
<memory>XXXXXX</memory> <--- XXXXXX is (number of gigabytes of memory * 1024 * 1024)
<currentMemory>XXXXXX</currentMemory> <--- XXXXXX Should be the same as the previous line

Start the VM

sudo virsh start "name_of_vm"

=== Adding disk space to a VM (file based VM)

Create a file containing the amount of space you want to add to the VM

sudo qemu-img create -f raw additional.raw <size>

Shutdown the VM ----- '''DO NOT SKIP THIS STEP. YOU WILL CORRUPT THE VM IF YOU DO THIS WHILE IT IS RUNNING'''

sudo virsh shutdown "name_of_vm"

Convert the VM to raw if needed

sudo qemu-img convert -f "name_of_vm".qcow2 -O raw "name_of_vm".raw

Add the additional space to the VM

sudo cat additional.raw >> "name_of_vm".raw
