Questions[system-properties](server)

A long time back on a production server of mine I had created a few virtual machines. On Ubuntu using virt-manager I have forgotten their configurations i.e. How much RAM did I allocate to those VM's can some one help me to figure that out.I have no clue as how to detect that part.

edit after some replies I am using KVM not Xen

free -m has following output

             total       used       free     shared    buffers     cached
Mem:          1002        956         45          0         30        151
-/+ buffers/cache:        774        228
Swap:         2015          0       2015

and the config file virtual_machine.xml has following entry which I think is the right line for RAM specification

 <memory>1048576</memory>
 <currentMemory>1048576</currentMemory>

but I am not able to understand what is that no in GB equal to.Here is the output of top command on the Virtual Machine

Mem:   1026868k total,   980080k used,    46788k free,    31508k buffers
Swap:  2064376k total,      104k used,  2064272k free,   155040k cached

For another virtual machine free -m has following

             total       used       free     shared    buffers     cached
Mem:          2009       1848        161          0        235        792
-/+ buffers/cache:        820       1189
Swap:         5847          1       5846

and its config file has

 <memory>2097152</memory>
  <currentMemory>2097152</currentMemory>

Now output of top -b -d 1 > top.txt command on host where all such guests are running is

top - 14:40:43 up 8 days,  4:01,  1 user,  load average: 0.68, 0.58, 0.55
Tasks: 259 total,   2 running, 256 sleeping,   0 stopped,   1 zombie
Cpu(s):  1.3%us,  4.2%sy,  0.0%ni, 94.4%id,  0.1%wa,  0.0%hi,  0.0%si,  0.0%st
Mem:   8181868k total,  8059876k used,   121992k free,   388564k buffers
Swap: 15624184k total,    63012k used, 15561172k free,  1596052k cached

How much is the memory Host has and how much is given to guest that is what I want to know.

The properties service (configured in properties-service.xml) in JBoss application server lets you specify external .properties files that are loaded and can then be accessed as system properties from the deployed applications.

(See here http://community.jboss.org/wiki/PropertiesService for more info...)

Is it also possible to load config files in the .xml format instead of .properties?

I know it is possible for certain given configs like for example the mail-service.xml and the jboss-log4j.xml... But they are both loaded directly by JBoss, and not via the properties service.

How can I set up Hudson CI so that I can send out emails from the server following a build failure? At the moment all I get is the following error:

com.sun.mail.smtp.SMTPSendFailedException: 530 5.7.0 Must issue a STARTTLS command first

One solution is to start Hudson as follows:

java -Dmail.smtp.starttls.enable="true" -jar /usr/share/hudson/hudson.war

However, I am already using the following to start Hudson:

sudo /etc/init.d/hudson start

I am thinking the solution is to somehow set the system property mail.smtp.starttls.enable in a property file somewhere, but I have no idea how to do that. What are my options?

Thank you all in advance!
