Hi everyone, 
On a host running Debian 8 with a plain vanilla kernel 3.18.25 amd64,
running several VMs, one of these freezes repeatedly.

This VM is running Debian Wheezy, kernel 3.2.0 (3.2.83), standard
Debian stock. Another VM running the same release never crashes.
However this one running ElasticSearch, crashes repeatedly.

Elastic Search is running atop Oracle Java :

java version "1.7.0_60"
Java(TM) SE Runtime Environment (build 1.7.0_60-b19)
Java HotSpot(TM) 64-Bit Server VM (build 24.60-b09, mixed mode)

Symptoms are that the VM freezes, CPU at 100%, won't reply to ping, and
must be killed. Therefore I suspected a kernel panic.

I've run 'vmstat 5 > /some/nfs/log' to see if the crashes are related
to heavy load, memory pressure, but no dice. The guest isn't
particularly loaded when crashing (this is the tail of the log):

procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu----

I have these weird logs entries on the host:

[14144268.854175] kvm [8922]: vcpu0 unimplemented perfctr wrmsr: 0xc0010004 data 0xabcd
[14419620.465102] kvm: zapping shadow pages for mmio generation wraparound

[14450007.904546] kvm [23985]: vcpu0 unimplemented perfctr wrmsr: 0xc0010004 data 0xabcd

And they may come at about the same time as the VM crashes, but not
always. So it's rather inconclusive.

The VM guest has tons of these in its logs, and I have no idea of where
it comes from:

Lately after days pulling my hair, for some reason netconsole finally
deigned providing a kernel dump, which doesn't speak much to me except
that it's java which is crashing everything down:
