https://bugzilla.redhat.com/show_bug.cgi?id=888426 The code for doing a block-copy was supposed to track the destination file in drive->mirror, but was set up to do all mallocs prior to starting the copy so that OOM wouldn't leave things partially started. However, the wrong variable was being written; later in the code we silently did 'disk->mirror = mirror' which was still NULL, and thus leaking memory and leaving libvirt to think that the mirror job was never started, which prevented a pivot operation after a copy. * src/qemu/qemu_driver.c (qemuDomainBlockCopy): Initialize correct variable. --- src/qemu/qemu_driver.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 7d8dd21..184f852 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -13429,7 +13429,7 @@ qemuDomainBlockCopy(virDomainPtr dom, const char *path, } if (!format && disk->mirrorFormat > 0) format = virStorageFileFormatTypeToString(disk->mirrorFormat); - if (!(disk->mirror = strdup(dest))) { + if (!(mirror = strdup(dest))) { virReportOOMError(); goto endjob; } -- 1.7.1 -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
