It seems extremely unlikely that there is any relationship there. I
normally run my qemus with -vnc, occasionally with default console, but
never with -nographic, and have never seen any connectivity problems
between them. My host machine isn't slow, but ping is about the least
resource-intensive thing you can do network-wise.

I would guess that you had the bridge setup messed up somehow when ping
didn't work, or possibly a local firewall on one of the guest OSes got
in the way. Assuming that both guest systems were actually running at
all, that is - firing up two qemus running KDE/Gnome or somesuch on a
slow machine could probably make everything grind to a halt, but you
don't have to run a window system just because you run in "graphic
mode".
