Re: [libvirt-users] libvirt 4.1 and later - howto configure LXC with interface macvlan type='direct' ?

Hi all After upgrade from Centos 7.5 to Centos 7.6, our test environment geted new version of libvirt 4.5.0 In which our old containers have broken config and can't start: 2018-12-05 10:38:32.634+0000: 18010: debug : virLXCControllerGetNICIndexes:368 : Getting nic indexes 2018-12-05 10:38:32.634+0000: 18010: error : virLXCControllerGetNICIndexes:400 : unsupported configuration: Unsupported net type direct Failure in libvirt_lxc startup: unsupported configuration: Unsupported net type direct We use next section for network interface: <interface type='direct'> <mac address='02:00:21:3b:eb:e1'/> <source dev='eno1.710' mode='bridge'/> </interface> It's linux macvlan solutions and it's worked at least since libvirt 1.2.7 for us. As I can see, in version 4.1.0 and later, some changes about DIRECT connect was implemented. VIR_DOMAIN_NET_TYPE_DIRECT is still fully supported in src/lxc/lxc_driver.c But in src/lxc/lxc_controller.c --- libvirt-3.9.0/src/lxc/lxc_controller.c 2017-09-28 13:15:43.322712913 +0300 +++ libvirt-4.1.0/src/lxc/lxc_controller.c 2018-02-28 16:21:05.158799006 +0300 @@ -395,8 +395,14 @@ case VIR_DOMAIN_NET_TYPE_INTERNAL: case VIR_DOMAIN_NET_TYPE_DIRECT: case VIR_DOMAIN_NET_TYPE_HOSTDEV: + virReportError(VIR_ERR_CONFIG_UNSUPPORTED, + _("Unsupported net type %s"), + virDomainNetTypeToString(ctrl->def->nets[i]->type)); + goto cleanup; + case VIR_DOMAIN_NET_TYPE_LAST: default: - break; + virReportEnumRangeError(virDomainNetType, ctrl->def->nets[i]->type); + goto cleanup; } } Since version 4.1.0 which config need be used to configure macvlan for lxc cointainers ?
