Yes, the rsb log for building qemu indicated *no* vde support. So I 
obtained and make/installed "vde2" from soureforge since there is no vde 
package in fedora. Now the log indicates vde supported after qemu 
rebuild via rsb.

I did this:
sudo /usr/local/bin/vde_switch -F --tap tap0 -sock /tmp/myswitch
and I see new the tap interface:
[gene at hplt ~]$ ifconfig -a
tap0: flags=4098<BROADCAST,MULTICAST>  mtu 1500
         ether 52:4b:a3:d2:f4:08  txqueuelen 500  (Ethernet)
         RX packets 3  bytes 159 (159.0 B)
         RX errors 0  dropped 0  overruns 0  frame 0
         TX packets 0  bytes 0 (0.0 B)
         TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

Running qemu I get this:
[gene at hplt ~]$ qemu-system-arm
qemu-system-arm: error while loading shared libraries: libvdeplug.so.3: 
cannot open shared object file: No such file

Fix with this (since vde2 default installs libs in non-fedora place, I 
assume):
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib

Ping01 test seems "easy" but when I run it I see this:

[gene at hplt ping01]$ sudo LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib 
/home/gene/rtems/install/4.11/qemu/bin/qemu-system-arm -M

Obviously, I am doing something very wrong or incomplete here! FYI, the 
config.inc file I used to build rtems-libbsd is attached. (Also, I am 
still needing root access.)
