Description Humble Chirammal 2010-10-02 12:23:05 UTC

Description of problem:


virsh reports an improper message when virt-domjobabort is run.
If we run #virt-domjobabort to a guest OS during "virsh dump" and
virsh aborts with the following message.

# virsh dump <domain-name> <core-file-path>
error: Failed to core dump domain <domain-name> to <corefilepath>
error: operation failed: Migration was cancelled by client

As you see, virsh said that migration was cancelled although there is no
operation for the guest OS migration. The said error message is reported
as well in the following case.

- save
- managedsave
- migrate

In the case of "virsh migrate", the said message is proper.

Red Hat Enterprise Linux Version Number: 6

Architecture: x86_64
Kernel Version: kernel-2.6.32-71.el6.x86_64
Related Package Version: libvirt-client-0.8.1-27.el6.x86_64 



How reproducible:

Always

Steps to Reproduce:
1. Start up a guest OS.
# virsh start <domain-name>
2. Dump a core file of the guest OS.
# virsh dump <domain-name> <core-file-path> &
3. Abort the core dump just after the above step2.
# virsh domjobabort <domain-name>
<The said error message should be reported.>

Expected Results: virsh reports a proper message when virt-domjobabort is run.

this is caused by migration, save, dump, and "managed save" use the same basic function, the error messages should be splited.
