Hello, In my C++ code, I generate my own domain XML file and I use virDomainCreateXML or virDomainDefineXML to launch my qemu VM. However, when I get to check which commands are sent to the qemu commandline, I find that libvirt has added so many extra parameters to the ones I have already set. How can I prevent libvirt from adding any extra parameters to the ones I originally defined in the

The main motivation for this patch is to enable cloud service providers to provide an accelerated datapath to virtio-net enabled VMs in a transparent manner with no/minimal guest userspace changes. This also enables hypervisor controlled live migration to be supported with VMs that have direct attached SR-IOV VF devices. Patch 1 introduces a failover module that provides a generic interface for
