[libvirt] [PATCHv2 5/6] util: use new virTypedParameter helpers

Reusing common code makes things smaller; it also buys us some additional safety, such as now rejecting duplicate parameters during a set operation. * src/qemu/qemu_driver.c (qemuDomainSetBlkioParameters) (qemuDomainSetMemoryParameters, qemuDomainSetNumaParameters) (qemuSetSchedulerParametersFlags) (qemuDomainSetInterfaceParameters, qemuDomainSetBlockIoTune) (qemuDomainGetBlkioParameters, qemuDomainGetMemoryParameters) (qemuDomainGetNumaParameters, qemuGetSchedulerParametersFlags) (qemuDomainBlockStatsFlags, qemuDomainGetInterfaceParameters) (qemuDomainGetBlockIoTune): Use new helpers. * src/esx/esx_driver.c (esxDomainSetSchedulerParametersFlags) (esxDomainSetMemoryParameters) (esxDomainGetSchedulerParametersFlags) (esxDomainGetMemoryParameters): Likewise. * src/libxl/libxl_driver.c (libxlDomainSetSchedulerParametersFlags) (libxlDomainGetSchedulerParametersFlags): Likewise. * src/lxc/lxc_driver.c (lxcDomainSetMemoryParameters) (lxcSetSchedulerParametersFlags, lxcDomainSetBlkioParameters) (lxcDomainGetMemoryParameters, lxcGetSchedulerParametersFlags) (lxcDomainGetBlkioParameters): Likewise. * src/test/test_driver.c (testDomainSetSchedulerParamsFlags) (testDomainGetSchedulerParamsFlags): Likewise. * src/xen/xen_hypervisor.c (xenHypervisorSetSchedulerParameters) (xenHypervisorGetSchedulerParameters): Likewise. --- src/esx/esx_driver.c | 81 +++--- src/libxl/libxl_driver.c | 44 +--- src/lxc/lxc_driver.c | 218 +++++----------- src/qemu/qemu_driver.c | 656 ++++++++++++++-------------------------------- src/test/test_driver.c | 27 +-- src/xen/xen_hypervisor.c | 51 ++-- 6 files changed, 350 insertions(+), 727 deletions(-) diff --git a/src/esx/esx_driver.c b/src/esx/esx_driver.c index 1e424eb..63cdba5 100644 --- a/src/esx/esx_driver.c +++ b/src/esx/esx_driver.c @@ -32,6 +32,7 @@ #include "logging.h" #include "uuid.h" #include "vmx.h" +#include "virtypedparam.h" #include "esx_driver.h" #include "esx_interface_driver.h" #include "esx_network_driver.h" @@ -3660,43 +3661,38 @@ esxDomainGetSchedulerParametersFlags(virDomainPtr domain, dynamicProperty = dynamicProperty->_next) { if (STREQ(dynamicProperty->name, "config.cpuAllocation.reservation") && !
