hi,all

we can pass value throught xml when start vm.  how to adjust the value dynamicly as needed  while vm is running via API calls?

for example , change from 

 <filterref filter='hcount'>
        <parameter name='HC' value='6'/>
        <parameter name='HC' value='10'/>
      </filterref>

to

<filterref filter='hcount'>
<parameter name='HC' value='16'/>
<parameter name='HC' value='20'/>
</filterref>

i do not want to restart or interrupt  the running state of vms(via api, not command line tools).
