I have a system with two CentOS 7.1 guests. When I created the VMs I did not have enough storage space in the default location /var/lib/libvirt/images so I moved the default location to a directory /home/vmimages. While this configuration is functional I regret creating a new storage pool in /home. I would like to create a separate partition to place the VM images removing them from their present /home/images location. The /home partition is presently empty other than the VM images directory so I can easily steal space from it (using only ~4% of 500GB). However, I have a problem. Namely /home is an XFS file system so I cannot shrink the partition in order to make space for the desired new VM images partition. I was wondering if this procedure might work to do what I desire:
1.) Shutdown the VMs 2.) Archive the VM image directory /home/vmimages to a network drive (don't have space locally other than on /home) 3.) Use parted or fdisk to delete present /home partition 4.) Use parted or fdisk to re-create smaller/home partition and new /vm-images partition 5.) Create XFS file system on /home and /vm-images 6.) Extact VM image directory archive into /vm-images 7.) Use virt-manager to change default location of images to /vm-images
Is there any chance that after all this the VMs would actually start up again especially after a re-boot?
Thanks.
