<p class="MsoNormal">Hi all:<o:p></o:p></p>
<p class="MsoNormal"> I’m testing pci-passthrough with a AIO stx node(iso version:20190607T142331Z), after install completed,
<o:p></o:p></p>
<p class="MsoNormal">I found that there’s not enough memory reversed for my vms(server total memory is 64G,but only 7-8G can be allocated for vms),<o:p></o:p></p>
<p class="MsoNormal">Checked node with `system host-memory-list controller-0` and find that hugepages was configured and I did’t deply dpdk-ovs.<o:p></o:p></p>
<p class="MsoNormal">Here are my questions:<o:p></o:p></p>
