[libvirt] [PATCH 1/2] Fix error detection in device change

According to qemu-kvm/qerror.c all messages start with a capital "Device ", but the current code only scans for the lower case "device ". This results in "virDomainUpdateDeviceFlags()" to not detect locked CD-ROMs and reporting success even in the case of a failure: # virsh qemu-monitor-command "$VM" change\ drive-ide0-0-0\ \"/var/lib/libvirt/images/ucs_2.4-0-sec4-20110714145916-dvd-amd64.iso\" Device 'drive-ide0-0-0' is locked # virsh update-device "$VM" /dev/stdin <<<"<disk type='file' device='cdrom'><driver name='qemu' type='raw'/><source file='/var/lib/libvirt/images/ucs_2.4-0-sec4-20110714145916-dvd-amd64.iso'/><target dev='hda' bus='ide'/><readonly/><alias name='ide0-0-0'/><address type='drive' controller='0' bus='0' unit='0'/></disk>" Device updated successfully Signed-off-by: Philipp Hahn <hahn(a)univention.de&gt; --- src/qemu/qemu_monitor_text.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/src/qemu/qemu_monitor_text.c b/src/qemu/qemu_monitor_text.c index 52d924a..98d9169 100644 --- a/src/qemu/qemu_monitor_text.c +++ b/src/qemu/qemu_monitor_text.c @@ -1064,7 +1064,7 @@ int qemuMonitorTextChangeMedia(qemuMonitorPtr mon, /* If the command failed qemu prints: * device not found, device is locked ... * No message is printed on success it seems */ - if (strstr(reply, "device ")) { + if (c_strcasestr(reply, "device ")) { qemuReportError(VIR_ERR_OPERATION_FAILED, _("could not change media on %s: %s"), devname, reply); goto cleanup; -- 1.7.1
