Upstream "fixed" the issue - by finishing "block-commit" - in v1.3. That
is why I'm marking this bug as a duplicate of the Ubuntu bug. I'll
provide more comments in that bug.

Bug description:
Hi,
i´ve a Problem with committing a snapshot. The problem was discussed
on the libvirt mailing list earlier this year.
https://www.redhat.com/archives/libvirt-
users/2015-January/msg00029.html
Iam running gentoo and:
Compiled against library: libvirt 1.2.14
Using library: libvirt 1.2.14
Using API: QEMU 1.2.14
Running hypervisor: QEMU 2.3.0
I´am running a Windows Server 2012 R2 VM with the latest quest driver
(0.1.96) and QEMU quest Agent 0.12.1 installed.
The domain is started with following command line:
/usr/bin/qemu-system-x86_64 -name $DOMAIN -S -machine
pc-i440fx-1.6,accel=kvm,usb=off -m 8192 -realtime mlock=off -smp

virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x4 -msg timestamp=on
char device redirected to /dev/pts/2 (label charserial0)
I´ve created the snapshot with:
virsh # snapshot-create-as --domain $DOMAIN snap1 --diskspec
vda,file=/var/lib/libvirt/images/snap1.qcow2 --quiesce --disk-only --atomic
--no-metadata
Domain snapshot snap1 created
If i try to commit the snapshot i get this error:
virsh # blockcommit $DOMAIN vda --active --verbose --pivot
error: internal error: unable to execute QEMU command 'block-commit': Device
'drive-virtio-disk0' is busy: block device is in use by block job: commit
virsh # blockjob $DOMAIN /var/lib/libvirt/images/snap1.qcow2

virsh # blockjob $DOMAIN /var/lib/libvirt/images/snap1.qcow2
No current block job for /var/lib/libvirt/images/snap1.qcow2
I´ve test this with qemu 2.1 and the problem does`nt exist.
