<p class="MsoPlainText">This change introduces support for preallocated shared file descriptor based memory backing.
<o:p></o:p></p>
<p class="MsoPlainText">It allows vhost-user to be used without hugepages. This is achieved by introducing 3 new sub elements to the memoryBacking element: source, access & allocation which will configure qemu commandline during VM startup accordingly.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">First patch adds parsing of elements and storing the values in mem structure.<o:p></o:p></p>
<p class="MsoPlainText">Second patch configures the qemu commandline on the base of values in mem structure.<o:p></o:p></p>
