Hi,
That is very alarming to hear. We have run the EMS on a variety of hosting providers and VM tools including Amazon, Rackspace, HP, Stream Guys, Digital Ocean, VMWare, Virtualbox and likely more. I spoke with OVH yesterday and they were unable to provide an answer to my question aside from that there is a custom kernel which they have and which may optionally be used during installation of your VM. Do you know if you chose to use that custom Kernel?
