RH-Commit: [4/4] b96bb671bcfb7ae18015fda14db70f42a83a6ea7 (kmwolf/centos-qemu-kvm)
|
|
|
7f1c5b |
|
|
|
7f1c5b |
This tests that when an error happens while writing back bitmaps to the
|
|
|
7f1c5b |
image file in qcow2_inactivate(), 'qemu-img bitmap/commit' actually
|
|
|
7f1c5b |
return an error value in their exit code instead of making the operation
|
|
|
7f1c5b |
look successful to scripts.
