[libvirt-users] "virsh define" modify xml configuration file

[d tbsky]

hi:
   I upgrade my system from rhel 7.3 to 7.4. so libvirt upgrade to 3.2.

   I found command "virsh define vm.xml" sometimes  modify "vm.xml". I
thought the command will read vm.xml, not write to it. is this kind of
behavior by design?

   for example vm.xml with the line

   <cpu mode='custom' match='exact'>

   will be replaced with

  <cpu mode='custom' match='exact' check='partial'>
