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.

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
