If by "dynamic virtual host" you mean some mass-vhosting solution,
then yes.

With normal vhosts, apache keeps information for each host in a separate
object. That includes both simple stuff like document root and more
expensive stuff like file descriptors for the logs. That's great for
a small number of hosts, but doesn't scale well to larger numbers.
So mass-virtual-hosting uses a single server_rec for all vhosts.
