Bug 1459183

Verified on libvirt-3.2.0-9.el7.x86_64, qemu-kvm-rhev-2.9.0-8.el7.x86_64, libvirt-python-3.2.0-3.el7.x86_64.

Scenario 1:
1. Define a persistent guest and blockcopy with flag VIR_DOMAIN_BLOCK_COPY_TRANSIENT_JOB. And then abort job.

# python
...
>>> import os
>>> import libvirt
>>> fd = open('/root/test.xml', 'rw')
>>> guestxml = fd.read()
>>> guestxml
"... <disk type='file' device='disk'>\n      <driver name='qemu' type='qcow2'/>\n      <source file='/var/lib/libvirt/images/libvirt-test-api'/>\n ..."
>>> conn = libvirt.open()
>>> dom = conn.defineXML(guestxml)
>>> dom.create()
0
>>> destxml = "<disk><source file='/tmp/test-api-blockcopy.img'/></disk>"
>>> dom.isPersistent()
1
>>> dom.isActive()
1
>>> dom.blockJobInfo('vda', 0)
{}
>>> dom.blockCopy("vda", destxml, None, libvirt.VIR_DOMAIN_BLOCK_COPY_TRANSIENT_JOB)
0
>>> dom.blockJobInfo('vda', 0)
{'end': 1291255808L, 'bandwidth': 0L, 'type': 2, 'cur': 375586816L}
>>> dom.blockJobAbort('vda')
0
>>> dom.blockJobInfo('vda', 0)
{}
>>> 

2. Check guest xml and xml don't be changed.
# virsh dumpxml test
...
    <disk type='file' device='disk'>
      <driver name='qemu' type='qcow2'/>
      <source file='/var/lib/libvirt/images/libvirt-test-api'/>
      <backingStore/>
      <target dev='vda' bus='virtio'/>
      <alias name='virtio-disk0'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/>
    </disk>
...


Scenario 2:

1. Define a persistent guest and blockcopy with flag VIR_DOMAIN_BLOCK_COPY_TRANSIENT_JOB. And then abort job with flag VIR_DOMAIN_BLOCK_JOB_ABORT_PIVOT.

>>> dom.destroy()
0
>>> dom.undefine()
0
>>> dom = conn.defineXML(guestxml)
>>> dom.create()
0
>>> dom.blockJobInfo('vda', 0)
{}
>>> dom.blockCopy("vda", destxml, None, libvirt.VIR_DOMAIN_BLOCK_COPY_TRANSIENT_JOB)
0
>>> dom.blockJobAbort('vda' ,libvirt.VIR_DOMAIN_BLOCK_JOB_ABORT_PIVOT)
0
>>> dom.blockJobInfo('vda', 0)
{}

2. Check guest xml, blockcopy completed.
# virsh dumpxml test
...
    <disk type='file' device='disk'>
      <driver name='qemu' type='qcow2'/>
      <source file='/tmp/test-api-blockcopy.img'/>
      <backingStore/>
      <target dev='vda' bus='virtio'/>
      <alias name='virtio-disk0'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/>
    </disk>
...
