             Summary: Scale CentOS7 VM fails with error 
                 Key: CLOUDSTACK-9690
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9690

    Affects Versions: 4.10.0.0
            Reporter: Sudhansu Sahu


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:
