Subject [jira] [Closed] (CLOUDSTACK-2107) Only scaling up memory(ram) in not triggering vm live migration ;Unable to scale vm due to Catch exception com.xensource.xenapi.Types$HostNotEnoughFreeMemory when scaling VM:i-2-35-VM due to Not enough host memory is available to perform this operation

]

prashant kumar mishra closed CLOUDSTACK-2107.
---------------------------------------------


it worked fine , 

->if scale up failed on current host, then allocator will assign an new potential host
in cluster .

>  For cpu scalup ,vms getting  live migrated to other host in cluster if no resources
are available on current host ,but not in case of RAM Scaleup 
> Steps to reproduce
> ----------------------------
> 1-Create zone->pod->cluster with one host
> 2-Deploy vm so that no resource left on host
> 3-Add another host in same cluster
> 4- Try to scale up vm's ram (in new service offering keep cpu speed same as previous
,increase ram by 500 MB)
> Expected
> --------------
> since there is no resource left on current host vm should get live migrate to other available
host and scaleup should be successful .
> Actual
> ---------
> scaleup failed due to not enough resource on current host,;CS did not try to live migrate
vm to other host on cluster
> My observation
> ----------------------
> 1-VM are getting live migrated in case of cpu scale up if current host does not have
resource
> 2-Tried to scaleup vm to service offering x failed but able to deploy a new vm with same
service offering
> Service offering details
