filter 0-device-weight when: - getting blkio parameters with --config - starting up a domain When testing with blkio, I found these issues: (dom is down) virsh blkiotune dom --device-weights /dev/sda,300,/dev/sdb,500 virsh blkiotune dom --device-weights /dev/sda,300,/dev/sdb,0 virsh blkiotune dom weight : 800 device_weight : /dev/sda,200,/dev/sdb,0 # issue 1: shows 0 device weight of /dev/sdb that may confuse user (continued) virsh start dom # issue 2: If /dev/sdb doesn't exist, libvirt refuses to bring the # dom up because it wants to set the device weight to 0 of a # non-existing device. Since 0 means no weight-limit, we really don't # have to set it.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
