[libvirt] [PATCHv4 0/9] Introduce driver specific callbacks and get rid of irrelevant data in virCaps
by Peter Krempa 31 Mar '13

31 Mar '13

This series now splits out almost everything from the virCaps object (except for the defaultConsoleTargetType callback that I will post later as It requires more tweaking). See notes in individual patches for change summary. Peter Krempa (9): conf: Add post XML parse callbacks and prepare for cleaning of virCaps qemu: Record the default NIC model in the domain XML virCaps: get rid of "defaultInitPath" value in the virCaps struct virCaps: get rid of defaultDiskDriverName virCaps: get rid of emulatorRequired conf: Enforce ranges on cputune variables virCaps: remove defaultDiskDriverType from the struct virCaps: Get rid of hasWideScsiBus virCaps: get rid of macPrefix field src/conf/capabilities.c | 24 --- src/conf/capabilities.h | 20 -- src/conf/domain_conf.c | 239 ++++++++++++++++----- src/conf/domain_conf.h | 40 +++- src/esx/esx_driver.c | 13 +- src/libvirt_private.syms | 6 +- src/libvirt_vmx.syms | 2 + src/libxl/libxl_conf.c | 2 - src/libxl/libxl_driver.c | 13 +- src/lxc/lxc_conf.c | 11 +- src/lxc/lxc_domain.c | 17 ++ src/lxc/lxc_domain.h | 1 + src/lxc/lxc_driver.c | 6 +- src/openvz/openvz_conf.c | 4 +- src/openvz/openvz_driver.c | 32 ++- src/parallels/parallels_driver.c | 12 +- src/phyp/phyp_driver.c | 10 +- src/qemu/qemu_capabilities.c | 6 - src/qemu/qemu_command.c | 15 +- src/qemu/qemu_conf.c | 14 +- src/qemu/qemu_conf.h | 3 +- src/qemu/qemu_domain.c | 89 ++++++++ src/qemu/qemu_domain.h | 1 + src/qemu/qemu_driver.c | 13 +- src/security/virt-aa-helper.c | 2 +- src/test/test_driver.c | 2 +- src/uml/uml_driver.c | 7 +- src/vbox/vbox_tmpl.c | 18 +- src/vmware/vmware_conf.c | 4 +- src/vmware/vmware_driver.c | 8 +- src/vmx/vmx.c | 39 ++-- src/vmx/vmx.h | 12 +- src/xen/xen_driver.c | 7 +- src/xen/xen_hypervisor.c | 2 - src/xen/xend_internal.c | 6 +- src/xen/xm_internal.c | 2 + src/xenapi/xenapi_driver.c | 2 +- tests/domainsnapshotxml2xmltest.c | 2 +- tests/lxcxml2xmldata/lxc-hostdev.xml | 1 + tests/lxcxml2xmldata/lxc-systemd.xml | 1 + tests/qemuargv2xmltest.c | 2 +- tests/qemumonitorjsontest.c | 2 +- .../qemuxml2argv-disk-drive-network-nbd.args | 5 +- .../qemuxml2argv-disk-drive-network-nbd.xml | 1 + .../qemuxml2argv-disk-drive-network-rbd-auth.args | 2 +- .../qemuxml2argv-disk-drive-network-rbd-ipv6.args | 2 +- .../qemuxml2argv-disk-drive-network-rbd-ipv6.xml | 1 + .../qemuxml2argv-disk-drive-network-rbd.args | 2 +- .../qemuxml2argv-disk-drive-network-rbd.xml | 1 + .../qemuxml2argv-disk-drive-network-sheepdog.args | 3 +- .../qemuxml2argv-disk-drive-network-sheepdog.xml | 1 + .../qemuxml2argv-net-bandwidth.xml | 1 + .../qemuxml2argvdata/qemuxml2argv-net-client.args | 4 +- .../qemuxml2argv-net-eth-ifname.args | 4 +- .../qemuxml2argv-net-eth-ifname.xml | 1 + .../qemuxml2argv-net-eth-names.args | 8 +- tests/qemuxml2argvdata/qemuxml2argv-net-eth.args | 4 +- tests/qemuxml2argvdata/qemuxml2argv-net-eth.xml | 1 + .../qemuxml2argvdata/qemuxml2argv-net-hostdev.xml | 1 + tests/qemuxml2argvdata/qemuxml2argv-net-mcast.args | 4 +- .../qemuxml2argv-net-openvswitch.xml | 1 + .../qemuxml2argvdata/qemuxml2argv-net-server.args | 4 +- tests/qemuxml2argvdata/qemuxml2argv-net-user.args | 3 +- tests/qemuxml2argvdata/qemuxml2argv-net-user.xml | 1 + .../qemuxml2argv-net-virtio-network-portgroup.xml | 2 + tests/qemuxml2argvtest.c | 2 +- .../qemuxml2xmlout-graphics-spice-timeout.xml | 1 + tests/qemuxml2xmltest.c | 2 +- tests/qemuxmlnstest.c | 2 +- tests/securityselinuxlabeltest.c | 2 +- tests/testutilsxen.c | 2 +- tests/vmx2xmltest.c | 11 +- tests/xml2vmxtest.c | 8 +- 73 files changed, 548 insertions(+), 251 deletions(-) -- 1.8.1.5

When logical pool has no PVs associated with itself (user-created), virCommandFree(cmd) is called twice with the same pointer and that causes a segfault in daemon.
