> Scale CentOS7 VM fails with error "Cannot scale up the vm because of memory constraint violation"
> When creating VM from CentOS 7 template on the XenServer with dynamically scaling enabled, instance starts with base specified memory instead of memory * 4 as static limit.
> As the result, attempt to scale VM throws error in MS log:
> {noformat}
> java.lang.RuntimeException: Job failed due to exception Unable to scale vm due to Catch exception com.cloud.utils.exception.CloudRuntimeException when scaling VM:i-24-3976-VM due to com.cloud.utils.exception.CloudRuntimeException: Cannot scale up the vm because of memory constraint violation: 0 <= memory-static-min(2147483648) <= memory-dynamic-min(8589934592) <= memory-dynamic-max(8589934592) <= memory-static-max(2147483648)
> {noformat}
> REPO STEPS
> =============================
> # Enable dynamic scaling in Global settings
> # Register an CentOS 7 tempplate(with tools) and tick dynamic scaling
> # Deploy VM with this template
> # Start the VM and try to change service offering
> EXPECTED RESULT: VM should start with static limit 4x<assigned memory> and scale up when offering is changed
> ACTUAL RESULT: VM starts with maximum static limit of <assigned memory> and doesn't scale up with error in ms log :
> Cannot scale up the vm because of memory constraint violation:
