Might be nice to make sure the user actually specifies M, G, etc. I tried echoing 60000 and forgot the K the first time. It fails pretty spectacularly when it tries to reduce the memory to 60000 bytes as I'm sure you know. :) On the other hand, if you want users to be able to give just a number and assume bytes, how about checking the number they provide against the amount of memory currently in use to see if it's likely to cause trouble? Or are there other issues here? Another thing I noticed... xen1:/proc/xen# free total used free shared buffers cached Mem: 62612 32148 30464 0 1848 7908 -/+ buffers/cache: 22392 40220 Swap: 262136 0 262136 xen1:/proc/xen# echo 50M > balloon xen1:/proc/xen# cat balloon Current allocation: 51200 kB Requested target: 51200 kB Low-mem balloon: 14336 kB High-mem balloon: 0 kB Xen hard limit: ??? kB xen1:/proc/xen# free total used free shared buffers cached Mem: 62612 42356 20256 0 1848 7908 -/+ buffers/cache: 32600 30012 Swap: 262136 0 262136 Shouldn't free get adjusted as well?
