Hi,
I followed the link [https://openwrt.org/docs/guide-user/virtualization/virtualbox-vm] and created a VM inside Virtual Box.
The VMs Configurations are as follows:
lxc-checkconfig
--- Namespaces ---
Namespaces: enabled
Utsname namespace: enabled
Ipc namespace: enabled
Pid namespace: enabled
User namespace: enabled
Network namespace: enabled
--- Control groups ---
Cgroups: enabled

Cgroup v2 mount points:
Cgroup v1 systemd controller: /usr/bin/lxc-checkconfig: line 167: printf \033[1;31m: not found
Cgroup v1 freezer controller: /usr/bin/lxc-checkconfig: line 174: printf \033[1;31m: not found
Cgroup v1 clone_children flag: enabled
Cgroup device: enabled
Cgroup sched: enabled
Cgroup cpu account: enabled
Cgroup memory controller: enabled
Cgroup cpuset: enabled

192.168.XX.XX 0x1 0x2 0a:00:27:00:00:03 * br-mng
The /etc/lxc/default.conf has the following entries
lxc.net.0.type = veth
lxc.network.link = br-mng
lxc.network.flags = up
lxc.network.hwaddr = 08:00:27:2b:c8:5f
ifconfig -a output on the VM is:
br-mng Link encap:Ethernet HWaddr 08:00:27:2B:C8:5F
--- Some lines ---
eth0 Link encap:Ethernet HWaddr 08:00:27:2B:C8:5F
--- Some lines ---
eth1 Link encap:Ethernet HWaddr 08:00:27:79:CB:CF
--- Some lines ---
eth2 Link encap:Ethernet HWaddr 08:00:27:4F:C7:A5
--- Some lines ---
lo Link encap:Local Loopback
--- Some lines ---
vethXH0YJS Link encap:Ethernet HWaddr FE:61:34:FE:61:12
--- Some lines ---
I created a OpenWRT 19.07 LXC container inside the VM. The container starts fine and i am able to perform lxc-attach and other basic operations.
In VM, the entries of /srv/lxc/MyContainer/config are:
lxc.net.0.type = veth
lxc.net.0.link = br-mng
lxc.net.0.flags = up
lxc.net.0.hwaddr = 08:00:27:2B:C8:5F
However the container doesn't have network access.
When i try to run opkg update command inside MyContainer, it throws error message Failed to establish connection
The ifconfig -a inside container show the entries as:
eth0 Link encap:Ethernet HWaddr 08:00:27:2B:C8:5F
--- Some Lines ---
lo Link encap:Local Loopback
--- Some Lines ---
The brctl show and /proc/net/arp commands give blank response inside container
Note: I also tried changing lxc.net.0.hwaddr of container as 08:00:27:79:CB:CF. Even this did not work.
Could you please help me to have network access from inside container.
Am i missing anything?
