I've invested in some SSD drives and want to run my Linux KVM guests from them (currently on a SATA array). The current location of the guests is /var/lib/libvirt/images. I have the SSD volume mounted on /mnt/ssd/. The VMs do some calendaring and mail stuff and would rather not power them off to just use a simple copy command while they're cold. How can I move my KVM guests to the /mnt/ssd/images/ directory and update the XML config for KVM? Found a similar question here (How to migrate a running KVM (with full disk copy) to another node?) but it involves moving a guest to another server - I just want to change the directory and move the image.
