答复: VM showing half of the provisioned memory.

[Star Guo <st...@ceph.me>]

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

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.
