Bug#784688: Thousands of "xen:balloon: Cannot add additional memory (-17) messages" despite dom0 ballooning disabled

[Chad Dougherty <crd@andrew.cmu.edu>]

I'm experiencing this bug too.  The effect is that one particular guest 
cannot transmit on its vif.

xl.conf has 'autoballoon="off"', /etc/default/grub has 
'GRUB_CMDLINE_XEN_DEFAULT="dom0_mem=2048M,max:2048M"'

Trying the 'xl mem-set 0 4065' from earlier in the thread results in:

root@xen4:/sys/devices/system/xen_memory/xen_memory0# xl mem-set 0 4065
libxl: error: libxl.c:4098:libxl_set_memory_target: memory_dynamic_max 
must be less than or equal to memory_static_max

Any updates on this issue?
Thanks!
