-----------------------------------------------
Summary: Ensure XStools to be there in template inorder to enable
dynamic scaling of vm
Key: CLOUDSTACK-2987
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-2987
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: Management Server
Affects Versions: 4.2.0, Future
Reporter: Harikrishna Patnala
Assignee: Harikrishna Patnala
Fix For: 4.2.0
XS tools need to be installed on the guest vm for Xenserver for memory dynamic
scaling and over provisioning to work.
XStools contain baloon drivers that are required to dynamically manipulate the
memory attributes (dynamic max/min). If they are altered at run time without
these tools, it can lead to unstable behavior for vm and potential crash. Both
for memory dynamic scaling and over provisioning this is required.
So we need to be able to ensure whether xstools are installed on the template
based on the user inputs while registering the template and use the same to set
different memory/cpu values to make dynamic scaling work.
