ok, after a small google search I found this blog http://kashyapc.com/2014/10/07/libvirt-blockcommit-shorten-disk-image- chain-by-live-merging-the-current-active-disk-content/
it seems that an upstream version of libvirt will allow libvirt users to commit back to the first file all the change made to a vm after an external disk snapshot. We will probably need to wait for libvirt 1.2.9 https://www.redhat.com/archives/libvirt-users/2014-October/msg00071.html How long will it takes? 16.04? :( Isn't here anyone able to make an update PPA of libvirt, qemu/kvm? cheers francesco -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1317491 Title: virsh blockcommit hangs at 100% To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1317491/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
