[libvirt] [PATCH v2 4/5] qemu: add NIC model checking for qemu hypervisor

As the enum virDomainNICModel is a big collection of NIC models for all of hypervisors, for qemu/kvm, only some of them are supported, so the patch tries to add a checking for NIC model that is qemu specific. The way of doing this is the same as VMX and Vbox do which have code to validate the hypervisor-specific NIC model in their implementation rather than domain XML parsing code. --- src/conf/domain_conf.h | 6 ++++++ src/qemu/qemu_command.c | 7 +++++++ 2 files changed, 13 insertions(+) diff --git a/src/conf/domain_conf.h b/src/conf/domain_conf.h index 76c1680..6ec2801 100644 --- a/src/conf/domain_conf.h +++ b/src/conf/domain_conf.h @@ -777,6 +777,12 @@ enum virDomainNICModel { VIR_DOMAIN_NIC_MODEL_PCNET, VIR_DOMAIN_NIC_MODEL_RTL8139, VIR_DOMAIN_NIC_MODEL_E1000, + + /* Add new NIC model for qemu above this. + */ + VIR_DOMAIN_NIC_MODEL_FOR_QEMU_END = + VIR_DOMAIN_NIC_MODEL_E1000, + VIR_DOMAIN_NIC_MODEL_NETFRONT, VIR_DOMAIN_NIC_MODEL_VLANCE, VIR_DOMAIN_NIC_MODEL_VMXNET, diff --git a/src/qemu/qemu_command.c b/src/qemu/qemu_command.c index 9ba27a1..fcd7512 100644 --- a/src/qemu/qemu_command.c +++ b/src/qemu/qemu_command.c @@ -6020,6 +6020,13 @@ qemuBuildCommandLine(virConnectPtr conn, else vlan = i; + if (net->model < 0 || net->model > VIR_DOMAIN_NIC_MODEL_FOR_QEMU_END) { + virReportError(VIR_ERR_CONFIG_UNSUPPORTED, + "NIC model '%s' is unsupported for QEMU", + virDomainNICModelTypeToString(net->model)); + goto error; + } + /* If appropriate, grab a physical device from the configured * network's pool of devices, or resolve bridge device name * to the one defined in the network definition. -- 1.7.11.2
