Hi Team

I'm trying to launch LXC VM with libvirt 1.2.12 having commit
*22cff52a2b8e06c913b1f97767e5d3**90fb17fc3b *with below XML configuration..

<domain type="lxc">

  <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>

Hmm indeed, it seems like that commit inadvertently dropped the error
condition for type=ethernet... from reading the original thread, I think the
reporter was only testing with qemu.

It's probably not much work to wire up type=ethernet for LXC, but someone
else
will need to do it. I'll send a patch to make the error explicit again.
Please
reopen your RFC bug

Thanks,
Cole

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.
