QEMU libraries are old that’s why online commit is not possible in your current qemu library, You need to install QEMU 2.1 ( and above), libvirt-1.2.9 (and above)

Lets say you have 3 snapshots, A B and C, taken in that order (thats C taken after B taken after A) with C as the current snapshot. If I want to delete the snapshots A and B, will the command still work. If yes, do you see potential problems of doing these?
