[PATCH Libvirt v3 10/10] virsh: Introduce command 'virsh domstats --dirtylimit'

From: Hyman Huang(黄勇) <yong.huang(a)smartx.com&gt; Introduce command 'virsh domstats --dirtylimit' for reporting dirty page rate upper limit (megabyte/s) infomation. The info is listed as follows: Domain: 'vm' dirtylimit.vcpu.0.limit=10 dirtylimit.vcpu.0.current=16 dirtylimit.vcpu.1.limit=10 dirtylimit.vcpu.1.current=0 ...
