This can not be fixed in libxl because libxl can not possibly know what is inside the domU. With '-machine xenfv' the PCI device is at 0000:00:02.0/platform, while with '-machine pc-i440fx-3.1,accel=xen -device xen-platform' the PCI device is somewhere else. As a result the receiving host rejects this approach: qemu-system-i386: Unknown savevm section or instance '0000:00:02.0/platform' 0. Make sure that your current VM setup matches your saved VM setup, including any hotplugged devices In my earlier testing I forced -machine pc-i440fx* on the sending side, and did not spot the flaw in this patch for libxl. For short: we are doomed... Olaf
