Question about instance volumes
I am seeing a behavior that I would like to ask about.
I have some instances that instead of having a normal qcow2 disk file, have
a qcow2 file that points to another backing store file.
<disk type='file' device='disk'>
<driver name='qemu' type='qcow2' cache='none'/>
<backingStore type='file' index='1'>
<target dev='vda' bus='virtio'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x04'
I am reading online that this is seen when there is a snapshot of another
disk file, but I have no snapshots, just a regular Linux server that I
created through the Cloudstack UI.
Any idea of why this would happen? Not all Instances have this backing
