It can be used to adjust (or disable) the size of the 64-bit PCI hole. The size attribute is in kilobytes (different unit can be specified on input), but it gets rounded up to the nearest GB by QEMU.
Disabling it will be needed for guests that crash with the 64-bit PCI hole (like Windows XP), see: https://bugzilla.redhat.com/show_bug.cgi?id=990418 --- docs/formatdomain.html.in | 9 ++++++ docs/schemas/domaincommon.rng | 32 +++++++++++++++------ src/conf/domain_conf.c | 26 +++++++++++++++-- src/conf/domain_conf.h | 8 ++++++ .../qemuxml2argv-pcihole64-gib.xml | 23 +++++++++++++++ .../qemuxml2argv-pcihole64-none.xml | 23 +++++++++++++++ .../qemuxml2argv-pcihole64-q35.xml | 33 ++++++++++++++++++++++ tests/qemuxml2argvdata/qemuxml2argv-pcihole64.xml | 23 +++++++++++++++ .../qemuxml2xmlout-pcihole64-gib.xml | 23 +++++++++++++++ tests/qemuxml2xmltest.c | 5 ++++ 10 files changed, 195 insertions(+), 10 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-pcihole64-gib.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-pcihole64-none.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-pcihole64-q35.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-pcihole64.xml create mode 100644 tests/qemuxml2xmloutdata/qemuxml2xmlout-pcihole64-gib.xml
ACK though it'd be good to get a second ack on the XML design before pushing.
