I
am doing an experiment which involves detecting co-resident VMs
(testing if 2 VMs are on the same physical machine) on KVM. I have tried
using cache covert channel, but this test does not work if the VMs are
on different processors within the same host as the caches are not shared then. If I use the tools netperf and iperf to differentiate using
network channels, I am not getting clear results. This is because the network is really good (10 Gbps). I believe there are better and more reliable ways for the
same. Please suggest some of these.
The idea is to find some resource (like memory, disk, etc) that is shared by the VMs and try to run some benchmarks that thrash this resource. Another idea is to take advantage of some optimization that kvm might be doing internally. Please help me.
Thank you
