Binary package hint: qemu-kvm

There seems to be a huge memory leak in qemu/kvm 0.12.3. After a while, a virtual machine is using much more memory on the host system, than actually is in use on the guest system. A guest system with only 512 MB assigned, can even use multiple GB's of memory.

This bug is also discussed here:

Would it be possible to fix this bug in Ubuntu? It makes KVM a bit useless currently, because running 2 GB of VM's can even cost 16 GB of memory.
