Hi , Kindly look below feature request. Almost all functions in OpenNebula and sunstone are good and am satisfied with it. But am facing some difficulties with absents of below features . I think it most important function for every cloud services . 1 . VM Backup . There is no option to backup a running VM in current OpenNebula . This is much needed one. Or there is no option for VM export in “qcow2” or “raw” formats …etc . 2 . VM Disk resize I can able to resize VM Memory , but not able to resize stopped VM disk size . If i need to increase VM space i need to add another disk to that VM . Is there any option to resize vm base storage like vmware and xen ? 3 . VM live migration including snapshots . I am able to live migrate VM without any snapshot attached on it . But when i took snapshot and went for live migration server is giving error. `migrate: Command "virsh --connect qemu:///system migrate --live one-9 qemu+ssh://node2.cloud.ae/system" failed: error: Requested operation is not valid: cannot migrate domain with 1 snapshots` Is this is a bug with QEMU or Opennebula?
