Yeah, libvirt does the same thing. It creates a virtual tap device which you can put your vms on, then it runs dnsmasq on that interface for dhcp/dns, and acts as a NAT/gateway for the vms. It's pretty much the same thing AFAICT. I'm sure there are differences but they sound pretty similar to me.

I read this document, and it seems to be doing basically what you get with libvirt, except libvirt does all that for you (but uses brctl instead of vde (I'm not sure what the differences are)). Anyway it seems like libvirt may be another alternative for you. It takes care of the bridging/dnsmasq/masquerading stuff for you and also has some nice management features (and a gui). -a

Re: [gentoo-user] vde_switch cannot create tap
BTW, the issue i had have been resolved. the document did not mention that i should add '-d' option to let the vde_switch run in daemon mode. -- Best Regards, David Shen http://twitter.com/davidshen84/
