    Subject[PATCH v3 0/1]
    Date
    This patch adds a few lines to the KVM common code to fire a
    KOBJ_CHANGE uevent whenever a KVM VM is created or destroyed. The event
    carries five environment variables:

    CREATED indicates how many times a new VM has been created. It is
    useful for example to trigger specific actions when the first
    VM is started
    COUNT indicates how many VMs are currently active. This can be used for
    logging or monitoring purposes
    PID has the pid of the KVM process that has been started or stopped.
    This can be used to perform process-specific tuning.
    STATS_PATH contains the path in debugfs to the directory with all the
    runtime statistics for this VM. This is useful for performance
    monitoring and profiling.
    EVENT described the type of event, its value can be either "create" or
    "destroy"

    Specific udev rules can be then set up in userspace to deal with the
    creation or destruction of VMs as needed.

    v2 -> v3:
    * added EVENT
    * shortened the names of the other variables

    v1 -> v2:
    * added KVM_VM_PID and KVM_VM_STATS_PATH
    * some cleanup, the patch should look nicer now
    * rebased on 4.12

    *** BLURB HERE ***
