# Create new disk image file | |||
#* EG <code> qemu-img create -f qcow2 /var/lib/libvirt/images/elk-disk1.img 20G </code> | |||
# Attach disk image to virtual machine | |||
#* Use <code>df</code> in the VM to determine next disk label, eg <code>vdb</code> | |||
#* EG <code> qemu-img create -f qcow2 /var/lib/libvirt/images/elk-disk1.img 20G -o preallocation=full </code> | |||
#** To create a thin provisioned file use the following (however you may find the disk the OS sees is small (~200K), if so, use the command above) | |||
#** EG <code> virsh attach-disk elk /var/lib/libvirt/images/elk-disk1.img vdb --cache none </code> | |||
# Update file owner and group to match other disk images | |||
#* EG <code> chown libvirt-qemu /var/lib/libvirt/images/elk-disk1.img </code> | |||
#* EG <code> chgrp libvirt-qemu /var/lib/libvirt/images/elk-disk1.img </code> | |||
# Attach disk | |||
#* EG <code> virsh attach-disk --domain elk /var/lib/libvirt/images/elk-disk1.img --target vdb --persistent --config --live </code> | |||
# In the VM, format the disk using defaults.. | |||
#* EG <code> fdisk /dev/vdb </code> | |||
#** EG <code>Command: n </code> | |||
#** EG <code>Partition type: p, </code> | |||
#** EG <code>Partition number: <default>, </code> | |||
#** EG <code>First sector: <default> </code> | |||
#** EG <code>Last sector: <default> </code> | |||
#** EG <code>Command: w </code> | |||
# Format new partition | |||
#* EG <code> mkfs.ext4 /dev/vdb1 </code> | |||
# Create mount directory | |||
#* EG <code> mkdir /vdb1/ </code> | |||
# Mount the the disk | |||
#* EG <code> mount /dev/vdb1 /vdb1/ </code> | |||
# Add an appropriate entry to fstab so the disk gets mounted on next boot | |||
#* EG <code> /dev/vdb1 /vdb1 ext4 defaults 0 0 </code> | |||
