------- Comment #12 from pbonzini@xxxxxxxxxx  2010-12-07 02:33 -------
This will be fixed in RHEL/CentOS 5.6.  The cause is usually ballooning.

The workaround that you can apply in older guests is to add the rx_copy=1
option to netfront.  Unfortunately that is not enough, as you need the patch of
https://bugzilla.redhat.com/show_bug.cgi?id=653501 in the host.  This one is
also scheduled for 5.6, but it will also be backported to 5.5.
