Subject: 8 nics limits on KVM ??
Date: Thu, 29 Jan 2009 15:24:46 +0100	[thread overview]
Message-ID: <4981BC2E.1010902@univ-nantes.fr> (raw)

Hello,

we are using kvm for wifidog, a wifi portal. In our case, we have lots 
of VLANS, and those vlans are connected  on separate bridges on the 
host. So, for the kvm machine running wifidog, we're having lots of 
virtual nics (more than 10). Launching kvm, we had this error mesage : 
Too many nics.

The limit seems hardcoded in qemu (in qemu/net.h), I've changed MAX_NICS 
from 8 to 24, and this seems to do the trick.

Is there any adverse effects doing this ? Is the limit arbitrary , or 
there for a good reason ?

Cheers,
