 Review comment:
   Is this if statement still required to check if debug is enabled?

>             Project: CloudStack
>          Issue Type: New Feature
>      Security Level: Public(Anyone can view this level - this is the 
> default.) 
>          Components: SystemVM, Virtual Router, XenServer
>    Affects Versions: 4.10.0.0, 4.9.3.0
>            Reporter: Pierre-Luc Dion
>            Priority: Major
>
> Following the recent Meltdown-Spectre security risk,one of the mitigation,as 
> of Jan 2018, for XenServer Hypervisor is to run Virtual-Machine in HVM mode.
> Currently SystemVMs and Virtual-Routers run as PV on XenServer and the eth0 
> is configured using {{/etc/init.d/cloud-early-config}} using grub params from 
> {{/proc/cmdline}}. When VM run as HVM, it is not possible to push initial 
> boot instruction via pygrub.
> Quick tests has been done using xenstore and it look like it would be 
> possible to send same initial boot instruction has pygrub but using xenstore 
> for HVM instances.
