Subject Re: [QUESTION] ACS 4.8 Centos 7 ARM / Raspberry PI B 2 with Intel KVM hypervisor
Date Tue, 17 May 2016 18:50:54 GMT
Daan:  Thanks for the response.


   I have been fighting memory constraints, on the Raspberry PI Management
Server.
   I have moved the DataBase process off to a separate Raspberry Pi.

   I have tried with KVM and  XenServer 6.5 hosts. Once I get the host
added I get out of memory errors in the management server logs.

   Is there a way to disable the some resources I will never use.   Some of
the Hypervisors and 3rd party network devices.

   The Idea of a small low power management server for small scale
deployment seemed nice.

 I am running cloudstack-management-4.8.0-1.el7.centos.armv7hl.rpm

Here is my start command:  I have tried 768m, 800m, 825m, 875m, 900m   and
get similar results.

if [ -r "/etc/cloudstack/management/cloudmanagementserver.keystore" ] ; then

  JAVA_OPTS="-Djava.awt.headless=true -Dcom.sun.management.jmxremote=false
-Xmx875m -XX:+HeapDumpOnOutOfMemoryErro

r -XX:HeapDumpPath=/var/log/cloudstack/management/ -XX:PermSize=512M
-XX:MaxPermSize=800m -Djavax.net.ssl.trustSto

re=/etc/cloudstack/management/cloudmanagementserver.keystore
-Djavax.net.ssl.trustStorePassword=vmops.com -Djava.n

et.preferIPv4Stack=true -Djava.net.preferIPv4Addresses"

else

  JAVA_OPTS="-Djava.awt.headless=true -Dcom.sun.management.jmxremote=false
-Xmx875m -XX:+HeapDumpOnOutOfMemoryErro

r -XX:HeapDumpPath=/var/log/cloudstack/management/ -XX:PermSize=512M
-XX:MaxPermSize=800m -Djava.net.preferIPv4Sta

ck=true -Djava.net.preferIPv4Addresses"

fi

   Here is a sample of one of the errors I am getting

2016-05-17 11:38:34,517 ERROR [c.c.a.AlertManagerImpl]
(CapacityChecker:ctx-c9db3855) (logid:5e7f6432) Caught exception in
