CentOs 7 on Esxi with LXC


Dear all,

I tried to setup lxc the first time und have a trouble i cant’t fix.

I used a centos7 fresh install
on ext4 filesystem
with epel-release libvirt virt-manager lxc* and make a yum update
on a esxi host

stopped & disable firewalld
stopped & disable NetworkManager

setup bridge in virt-manager gui

brctl show
bridge name bridge id STP enabled interfaces
br0 8000.000c2972c6d0 yes ens192
virbr0 8000.525400fbe0f4 yes virbr0-nic

installed first lxc-container with:
lxc-create -n test_c7 -t centos – -R 7 -a x86_64

change host config to

lxc.network.type = veth
lxc.network.link = br0
lxc.network.name = eth0
lxc.network.ipv4 =
lxc.network.ipv4.gateway =
lxc.network.hwaddr = 00:16:3e:cc:5c:1d
lxc.network.flags = up
lxc.network.mtu = 1400

connect to test_c7 via ssh.

after install postfix, bind, &… webmin

I get only 10~12MB/s over the network! and I can’t find where this is limited.
normaly I reached over same config with on a contextvirtual host over samba 115MB/s
Please Help i NEED full speed.
