Yes, as the URL indicates, it's from 2012. And, most of the content there is valid. However, some things have changed, with recent improvements in QEMU and libvirt. E.g. from the "blockcommit" section in the doc, now (from QEMU 2.0) it is possible to merge down the current active layer into base. > - ubuntu: 14.04 > - qemu: 2.0.0 > - libvirt-bin 1.2.2-0ubuntu13.1.17 > > > if not, is there an updated version available somewhere? > Though I haven't updated that document to reflect current new reality, that details mentioned there are still relevant. However, Eric Blake has done an excellent talk on backing chains, snapshots, and their management at KVM Forum 2015. Here's the talk (slides are in the video description): https://www.youtube.com/watch?v=etIGp12RHRE -- Backing Chain management in QEMU and libvirt by Eric Blake > Right now mainly interested in internal snapshots (which can be taken > & removed on a running machine, if I am not mistaken) Yes, internal snapshots can be performed on a running guest (or offline). Compare and contrast them with external snapshots, to see what works best for your use case. -- /kashyap _______________________________________________ libvirt-users mailing list libvirt-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvirt-users
