Re: [libvirt-users] [Bug 1325687] network type="ethernet" not supported with LXC

Thanks Cole.

I need to use network type="ethernet" with LXC instead of Qemu.
I have reopened my bug.

Re: [libvirt-users] [Bug 1325687] network type="ethernet" not supported with LXC

Hi Cole

I tested the LXC VM with libvirt 1.2.12 after applying the patch
http://www.redhat.com/archives/libvir-list/2016-April/msg00505.html

I'm now getting following errors..

virsh -c lxc: start test
error: Failed to start domain test
error: internal error: Unsupported network type ethernet

I'm using the below XML file for launching LXC VM..

<domain type="lxc">
  <uuid>64c48da2-e318-4085-8b88-c980aab4de34</uuid>
  <name>test</name>
  <memory>524288</memory>
  <vcpu>1</vcpu>
  <os>
    <type machine="virt">exe</type>
    <cmdline>root=/dev/ram0 rw  console=ttyAMA0 rootwait
earlyprintk</cmdline>
    <init>/bin/sh</init>
  </os>
  <clock offset="utc"/>
  <devices>
    <file/>
    <interface type='ethernet'>
      <mac address='02:74:ff:9d:52:f5'/>
      <script path=''/>
      <target dev='tap74f2-f5'/>
    </interface>
    <console type="pty"/>
  </devices>
</domain>

Thanks
Abhishek Jain

Yes, that was the point of the patch, to make the error explicit. As stated in
the other email, it will take more work to make type=ethernet actually
functional with LXC.
