Subject 答复: VM showing half of the provisioned memory.
Date Thu, 15 Jan 2015 01:17:18 GMT
Dear Abdul,

If you set mem.overprovisioning.factor	!= 1 in global settings,kvm agent will set instance
currentMemory half of memory in libvirt. 
So you can edit /etc/cloudstack/agent/agent.properties and uncomment "vm.memballoon.disable=true",
and then restart kvm agent. When you { deploy new instance } or {shutdown instance then restart
}, the currentMemory equals memory you view the instance .

Best Regards,
Star Guo

主题: RE: VM showing half of the provisioned memory.

Thx Len for your suggestion. I am running kvm as a hypervisor I do remember while I creating
 vm I used template which has dynamically scalable. may be I will try creating new vm without
using dynamically scalable option and let you know.

Thx
AR.
