Re: [libvirt] [PATCH v2 1/1] fixed handling of sourceless disks in 'domblkinfo' cmd

virDomainGetBlockInfo() returns error if called on a disk with no source (a sourceless disk might be a removable media drive with no media in it, for instance an empty CDROM or floppy drive). So far this caused the virsh domblkinfo --all command to abort and ignore any remaining (not yet displayed) disk devices. This patch fixes the problem by first checking for existence of a <source> element in the corresponding XML. If none is found, we avoid calling virDomainGetBlockInfo() altogether as we know it's bound to fail in that case. https://bugzilla.redhat.com/show_bug.cgi?id=1619625 Signed-off-by: Pavel Mores <pmores(a)redhat.com&gt; --- tools/virsh-domain-monitor.c | 33 ++++++++++++++++++++------------- 1 file changed, 20 insertions(+), 13 deletions(-)
