Hi Abdul, This was something Len and I discussed a while back but I am still seeing strange behaviour in my current 4.3.2 test system.
What I am seeing is that Windows VMs get 4x the RAM allocated to them on the Hypervisor (XenServer) but the OS is also reporting 4x the RAM. Linux VMs are getting 2x the RAM allocated to them on the Hypervisor (XenServer) but the VM is still only reporting its allocated RAM. However if I recall when I first spotted this in earlier versions, Linux VMs would actually get LESS RAM allocated to them which sounds like what you are seeing. I'm sure I logged this as a bug and it looks like the behaviour has changed but it is still behaving strangely, at least on XenServer. I'm sticking with my previous advice to Len which was to not mark Templates as Dynamically Scalable. As Len points out, you simply change the Template configuration and then Stop/Start your VMs. Regards Geoff Higginbottom D: +44 20 3603 0542 | S: +44 20 3603 0540 | M: +447968161581 geoff.higginbot...@shapeblue.com -----Original Message----- From: len.bellem...@alternativenetworks.com [mailto:len.bellem...@alternativenetworks.com] Sent: 14 January 2015 16:43 To: users@cloudstack.apache.org Subject: RE: VM showing half of the provisioned memory. Hi Abdul, Are you running XenServer with Dynamic Scaling enabled on your templates? I had this issue and the only way to fix it was to disable the "Dynamically Scalable" option on my templates, then shut down my vms (not restart) and then bring them up again. After that they received all of the memory. This was only on Linux machines. Windows vms are fine. I am using ACS 4.3. It sounds like a bug to me, but not sure.

Hi, All the VM instances in ACS is showing half of the memory, actual provision to this particulate VM is 2GB but instance is showing only 1GB. could you please explain me why is this happening ? free -m total used free shared buffers cached Mem: 986 977 8 0 0 25 -/+ buffers/cache: 951 35 Swap: 8001 3995 4005 Regards, AR Find out more about ShapeBlue and our range of CloudStack related services IaaS Cloud Design & Build<http://shapeblue.com/iaas-cloud-design-and-build//> CSForge – rapid IaaS deployment framework<http://shapeblue.com/csforge/> CloudStack Consulting<http://shapeblue.com/cloudstack-consultancy/> CloudStack Software Engineering<http://shapeblue.com/cloudstack-software-engineering/> CloudStack Infrastructure Support<http://shapeblue.com/cloudstack-infrastructure-support/> CloudStack Bootcamp Training Courses<http://shapeblue.com/cloudstack-training/> This email and any attachments to it may be confidential and are intended solely for the use of the individual to whom it is addressed.
