[libvirt] [PATCH 0/2] use bool type for bool values
by Eric Blake 25 Nov '14

25 Nov '14

I stumbled into this one on work I'm doing with qemu blockinfo. The DBus interaction code was tricky enough to need to be its own patch; but I like the end result that clients reading a 'b' entry from virDBus code can now pass a sane 'bool*' instead of a weird 'int*' variable.

[libvirt] [PATCH 0/8] Add XML validation to the APIs
by Daniel P. Berrange 24 Nov '14

24 Nov '14

This proof of concept patch extends the virDomainDefineXML and virDomainCreateXML APIs so that they can validate the user supplied XML document against the RNG schemas. The virsh command will enable validation by default, it must be turned off with --skip-validation if desired. This series is not complete - The network, interface, storage pool, etc APIs are not wired up to support validation. - Only the QEMU virt driver is wired up to validate - The virsh edit command is not wired up to validate It is enough to demonstrate it working with 'virsh define' and the QEMU driver though. The biggest problem I see is the really awful error messages we get back from libxml2 when validation fails :-( They are essentially useless :-( Daniel P. Berrange (8): Add new virDomainDefineXMLFlags public API Add stub virDomainDefineXMLFlags impls Add virXMLValidateAgainstSchema helper method Fix use of flags when parsing/formatting snapshot domain XML Don't pass VIR_DOMAIN_XML_SECURE to virDomainDefParseString in phyp Fix flags passed to virDomainDefParseString by XenAPI driver Given virDomainDef parser & formatter their own flags Add support for schema validation when passing in XML include/libvirt/libvirt-domain.h | 9 ++ include/libvirt/virterror.h | 1 + src/bhyve/bhyve_driver.c | 21 ++- src/conf/domain_conf.c | 315 +++++++++++++++++++------------------- src/conf/domain_conf.h | 71 ++++++--- src/conf/snapshot_conf.c | 8 +- src/driver-hypervisor.h | 5 + src/esx/esx_driver.c | 23 ++- src/hyperv/hyperv_driver.c | 3 +- src/internal.h | 4 + src/libvirt-domain.c | 48 ++++++ src/libvirt_private.syms | 2 + src/libvirt_public.syms | 5 + src/libxl/libxl_domain.c | 2 +- src/libxl/libxl_driver.c | 35 +++-- src/libxl/libxl_migration.c | 6 +- src/lxc/lxc_driver.c | 25 ++- src/openvz/openvz_driver.c | 23 ++- src/parallels/parallels_driver.c | 11 +- src/phyp/phyp_driver.c | 7 +- src/qemu/qemu_domain.c | 10 +- src/qemu/qemu_driver.c | 48 ++++-- src/qemu/qemu_migration.c | 8 +- src/remote/remote_driver.c | 1 + src/remote/remote_protocol.x | 19 ++- src/remote_protocol-structs | 8 + src/test/test_driver.c | 31 ++-- src/uml/uml_driver.c | 22 ++- src/util/virerror.c | 6 + src/util/virxml.c | 74 +++++++++ src/util/virxml.h | 5 + src/vbox/vbox_common.c | 25 ++- src/vmware/vmware_driver.c | 19 ++- src/xen/xen_driver.c | 21 ++- src/xen/xend_internal.c | 6 +- src/xen/xm_internal.c | 4 +- src/xenapi/xenapi_driver.c | 15 +- tests/domainsnapshotxml2xmltest.c | 2 +- tests/lxcxml2xmltest.c | 4 +- tests/openvzutilstest.c | 2 +- tests/qemuhotplugtest.c | 6 +- tests/qemuxml2argvtest.c | 2 +- tests/qemuxml2xmltest.c | 9 +- tests/qemuxmlnstest.c | 2 +- tests/vmx2xmltest.c | 2 +- tests/xmconfigtest.c | 4 +- tests/xml2sexprtest.c | 2 +- tests/xml2vmxtest.c | 2 +- tools/virsh-domain.c | 19 ++- 49 files changed, 684 insertions(+), 318 deletions(-) -- 2.1.0

Ethernet interfaces in libvirt currently do not support bandwidth setting. For example, following xml file for an interface will not apply these settings to corresponding qdiscs. <interface type="ethernet"> <mac address="02:36:1d:18:2a:e4"/> <model type="virtio"/> <script path=""/> <target dev="tap361d182a-e4"/> <bandwidth> <inbound average="984" peak="1024" burst="64"/> <outbound average="2000" peak="2048" burst="128"/> </bandwidth> </interface> Signed-off-by: Anirban Chakraborty <abchak(a)juniper.net> --- src/conf/netdev_bandwidth_conf.c | 14 ++++++++++- src/conf/netdev_bandwidth_conf.h | 25 +++++++++++++++++++ src/libvirt_private.syms | 1 + src/lxc/lxc_driver.c | 8 +++++++ src/lxc/lxc_process.c | 52 +++++++++++++++++++++++----------------- src/qemu/qemu_command.c | 16 ++++++++----- src/qemu/qemu_hotplug.c | 12 ++++++++++ src/qemu/qemu_process.c | 4 ++++ src/util/virnetdevmacvlan.c | 10 -------- src/util/virnetdevmacvlan.h | 1 - 10 files changed, 103 insertions(+), 40 deletions(-) diff --git a/src/conf/netdev_bandwidth_conf.c b/src/conf/netdev_bandwidth_conf.c index 2e5b564..63a39e3 100644 --- a/src/conf/netdev_bandwidth_conf.c +++ b/src/conf/netdev_bandwidth_conf.c @@ -25,7 +25,6 @@ #include "netdev_bandwidth_conf.h" #include "virerror.h" #include "viralloc.h" -#include "domain_conf.h" #include "virstring.h" #define VIR_FROM_THIS VIR_FROM_NONE @@ -269,3 +268,16 @@ virNetDevBandwidthFormat(virNetDevBandwidthPtr def, virBufferPtr buf) cleanup: return ret;
