In v2 migration protocol, XML is obtained by calling domainGetXMLDesc. This includes the default USB controller in XML, which breaks migration to older libvirt (before 0.9.2).

Commit 409b5f549530e7b3a33f4505f2cad2e26896107c qemu: Emit compatible XML when migrating a domain only fixed this for v3 migration.

This patch uses the new VIR_DOMAIN_XML_MIGRATABLE flag (detected by VIR_DRV_FEATURE_XML_MIGRATABLE) to obtain XML without the default controller, enabling backward v2 migration. --- src/libvirt.c | 13 ++++++++++--- src/libvirt_internal.h | 5 +++++ src/qemu/qemu_driver.c | 1 + 3 files changed, 16 insertions(+), 3 deletions(-)
