Thanks for testing. I sent an request for inclusion of this commit in Wily.
I built a Vivid test kernel with a cherry-pick of commit 4e4bd36f97b1492f19b3329ac74ed313da13de34 The test kernel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1294283/vivid Can you test this kernel and see if it resolves this bug?

It should get additional memory when needed, but the total available memory in the VM stays at the intial 512 MiB and the kernel starts swapping instead of allocating more memory from the host.
