Re: [libvirt] [PATCH] snapshot: Mention disk-only snapshots in error message

When a disk-only snapshot is requested the domain is treated as if it was offline. This forbids to mix memory checkpoints with the DISK_ONLY flag. This patch improves the error message and mentions the restriction in the virsh man page. --- Note: this is techicaly a v2 as I've redone it after checking the code again after Eric's review. Difference to the previous version: - The check for --memspec and --disk-only together was removed from virsh - Error message while parsing the xml was improved
