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

Since version 4.1.0 which config need be used to configure macvlan for
lxc cointainers ?
