* tools/virsh.c: fix missing zero value judgement in cmdBlkiotune and correct vshError information. when weight is equal to 0, the cmdBlkiotune will not raise any error information when judge weight value first time, and execute else branch to judge weight value again, strncpy(temp->field, VIR_DOMAIN_BLKIO_WEIGHT, sizeof(temp->field)) will be not executed for ever. However, if and only if param->field is equal to VIR_DOMAIN_BLKIO_WEIGHT, underlying qemuDomainSetBlkioParameters function will check whether weight value is in range [100, 1000]. * how to reproduce? % virsh blkiotune ${guestname} --weight 0 Signed-off-by: NAlex Jia <ajia@redhat.com>
