<P><FONT SIZE=2>Hi All,<BR>
<BR>
I have installed using Xen and XenMan 0.6 for Managing the Virtual Machines.<BR>
I am able to monitor the VMs on the local host , but it fails for the remote machine.<BR>
XenMan.<BR>
<BR>
Using netsat -tan , I monitored that managed system listens on 8006 ,<BR>
but XenMan by default connects at 8005 on system XenMan is used to manage other remote machine VMs<BR>
<BR>
I tested it also changing the the managing system Port from 8005 to 8006<BR>
<BR>
Following log is generated in the XenMan side<BR>
When Managed Server Port 8006<BR>
Client (Managing Xen Port) 8005<BR>
