Hello
If I'm not terribly mistaken, looks like libvirt 1.2.1 does not
provide ability of merging only a subset of the entire chain of
backing files.
So, if I have a chain like this:
root <- a <-b <- c <- d <- active
... and I'd like to obtain a chain like this:
root <- c <- d <- active
... looks like it's not supported, since I'm trying the command
virsh blockpull domain --path /path/to/c --bandwidth 30 --base
/path/to/root (1)
... but it complains because --path /path/to/c is not
recognized, since only --path /path/to/active is acceptable:
virsh blockpull domain --path /path/to/active --bandwidth 30 --base
/path/to/root (2)
So, command (1) fails but command (2) succeeds.
The point is: How could I obtain the results I'm trying to achieve
via command (1) ?
I'm new to libvirt, but the article below made me think that what
I'm trying to do would be possible:

( see section on blockpull )
Thoughts?
For your information, my environment is:
Compiled against library: libvirt 1.2.1
Using library: libvirt 1.2.1
Using API: QEMU 1.2.1
Running hypervisor: QEMU 1.7.0
Running against daemon: 1.2.1
Thanks
