Create a flavour with disk size as 0
Hi I created a flavour with 512mb of ram and root disk size as 0. And launched a ubuntu cloud iamge. So how does it works without a hard disk size?
Also df -h says I have 2.2GB of free space. Can some one explain if the hard disk size is really required to provide or we can use it as 0 and it will expand as it grows .
ubuntu@test-no-root:~$ df -h Filesystem Size Used Avail Use% Mounted on udev 241M 12K 241M 1% /dev tmpfs 49M 332K 49M 1% /run /dev/vda1 2.2G 786M 1.3G 39% / none 4.0K 0 4.0K 0% /sys/fs/cgroup none 5.0M 0 5.0M 0% /run/lock none 245M 0 245M 0% /run/shm none 100M 0 100M 0% /run/user
It would eb good if some one explain me from where /dev/vda1 is taken. Also which is best practice to have size 0 and use the vm's or to be used with HDD size minimum 10 or 20 GB provided. Consider that I would be taking snapshots also.
