Looking through old bug tickets... I think you should rather use
hotpluggable memory here for the guests instead - or use a big swap
partition on the host. Anyway, this is not a bug, so closing this ticket
now.

Title:
qemu release memory to system
Status in QEMU:
Invalid
Bug description:
Qemu pre-allocates the maximum balloon amount which is inconvinient if
all of the memory is used up and some other system needs to be added
memory resource
eg:- I have 4GB RAM with 4 virtual systems to be run.
I want each of them to start with 1GB RAM with maximum 2GB possible. This is
not achievable since qemu pre-allocates the maximum balloon amount which is
2GBx4 systems . So to start all 4 systems the system needs 8GB RAM rather than
4GB RAM to start with although I have told initial balloon amount to be 1GB.
