--------------------------------------------
Summary: SystemVMs and VR to run as HVM on XenServer
Key: CLOUDSTACK-10232
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-10232
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
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.
