Public bug reported:
Setting arbitrary balloon target values locks up the guest in some cases crashes it, if the target memory is < used +~5% free.
Found while testing aggressive memory over-commit, scenarios.

Test Environment:

Ubuntu 13.10, Guest Linux Kernel 3.19, qemu 2.2.0 with following patches applied - balloon OOM enhancement
commit 5a10b7dbf904bfe01bb9fcc6298f7df09eed77d5
Author: Raushaniya Maksudova <rmaksudova@parallels.com>
Boot guest with '-balloon virtio', -qmp .... -hmp access
1. sudo info balloon | socat - tcp4-connect:127.0.0.1:4444
- or over qmp interface

2. Take memory down check free memory using (1)
3. Issue "sudo echo balloon XXX | socat - tcp4-connect:127.0.0.1:4444" - XXX is value in threshold mentioned above
and you get Guest lockup
ARM - samething except '-device virtio-balloon-device' used
Libvirt - virsh setmem causes same issue.

Looking through old bug tickets... can you still reproduce this issue
with the latest version of QEMU? ... anyway, this rather sounds like a
bug with the guest kernel to me, so in case this problem persists, you
likely should report this in the kernel bug tracker instead.
