This is why I chose to manage the value from the sysctl interface rather than just have it stored as a value in /proc. Whatever tool was used to migrate the vm could hopefully adjust the sysctl value on the guest. > > This is best taken care of from the host side. Not sure what you are getting at here. If you are running in a cloud environment, you purchase a VM with the understanding that you are getting certain resources. As this type of user I don't believe you have any access to the host to see this type of information. So the user still wouldnt have a way to confirm that they are receiving what they should be in the way of processor resources. Would you please elaborate a little more on this? > -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
