Seems that this fixes is applied only in 
staging/qemu-upstream-unstable.git (of xen's gits) but still not in 
qemu-upstream-unstable.git or stables ones.
Can be the cause of strange problem of "loop" of increase memory failing 
on hvm domUs start with xen 4.4, 4.5 and unstable with newer kernel even 
if domUs and dom0 have all fixed memory settings with balloning disabled?
Or is another memory bug in xen?
I have syslog and kern.log increasing some gb each days full of:
xen:balloon: reserve_additional_memory: add_memory() failed: -17
in one 4.5.0 dom0 also with kernel 3.16.7-ckt4-3~bpo70+1 with these 
applied: [xen] cancel ballooning if adding new memory failed (Closes: 
#776448)

Thanks for any reply and sorry for my bad english.
