Now, the existed disk files relationship look like: base <- snap1 <-snap2 <- current using disk file. Now I want to remove snap1 and snap2, and let current disk using the base image file as back file directly. Unfortunately, for some reason, I can not shutdown the vm, and exectue the "virsh blockpull" command. Can I execute the "virsh blockpull" while the vm is power on, and the application in the vm is not affected? </span></font></div><div><font face="verdana" size="2"><span style="line-height: 19px;">Thanks very much!</span></font></div><div><font face="verdana" size="2"><span style="line-height: 19px;">Daniel</span></font></div> </body></html>
