domU without network interfaces?

["Johnny C. Lam" <jlam%pkgsrc.org@localhost>]

Is it possible to create a guest domain without any network interfaces, 
e.g. set nics = 0 in the domain config file?  When I tried this and 
booted with the netbsd-INSTALL_XENU kernel, the boot hung after finding 
the disk devices.

        Thanks,
