Dan,
I just reply to the list since I do not want to clutter BZ:
While migrating VMs is easy (and the sampling is already running), can someone tell me the correct polling port to block with iptables?
Thanks, Hi Daniel,
there is indeed a memory profiling patch under discussion: http://gerrit.ovirt.org/#/c/32019/
but for your case we'll need a backport to 3.4.x and clearer install instructions, which I'll prepare as soon as possible. I updated the BZ (and are now blocking 54321/tcp on one of my hosts). and verified it is not reachable. As general info: This system I am using is my LAB / Test / eval setup for a final deployment for ovirt (then 3.5) in production; so it will go away some time in the future (a few weeks / months). If I am the only one experiencing this problem then you might be better of allocating resources elsewhere ;)
As for your question: if I understood correctly what you are asking (still catching up the thread), if you are trying to rule out the stats polling made by Engine to this bad leak, one simple way to test is just to shutdown Engine, and let VDSMs run unguarded on hypervisors. You'll be able to command these VDSMs using vdsClient or restarting Engine. As I said in my BZ comment this is not an option right now, but if understand the matter correctly IPTABLES reject should ultimately do the same?
In absence of commands from Engine VDSM will just sit idle and it will not do anything to VMs except it's own sampling.
