Unable to Start the Virtual Machine Console
When you attempt to open a virtual machine console from the vSphere Web Client, the console does not
open.
Problem
When you attempt to open a virtual machine console from the vSphere Web Client, the console does not
open. The following error message appears:
HTTP ERROR 404
Problem accessin /. Reason:
Not Found
Errors similar to the following appear in the virgo-server.log file:
[2012-10-03 18:34:19.170] [ERROR] Thread-40
System.err
2012-10-03
18:34:19.167:WARN:oejuc.AbstractLifeCycle:FAILED org.eclipse.jetty.server.Server@315b0333:
java.net.BindException: Address already in use
[2012-10-03 18:34:19.170] [ERROR] Thread-40 System.err java.net.BindException: Address already
in use
Cause
Another program or process is using port 9443, the default port used by the HTML5 virtual machine
console.
Solution
u
Edit the webclient.properties file to add the line html.console.port=port, where port is the new port
number.
The webclient.properties file is located in one of the following locations, depending on the operating
system on the machine on which the vSphere Web Client is installed:
Windows 2008
C:\ProgramData\VMware\vCenterServer\cfg\vsphere-client\
vCenter Server Appliance
/var/lib/vmware/vsphere-client/
Unable to View the Alarm Definitions Tab of a Data Center
You might be unable to view the alarm definitions for a data center object in the vSphere Web Client.
Problem
When you click the Alarm Definitions tab on the Manage tab of a data center, the tab appears darkened by
a translucent overlay and no error message appears.
Cause
Inability to view the alarm definitions might be caused by insufficient memory. Problems that occur on the
vCenter Server side should result in an error message, but lack of available memory for Adobe Flash Player
on the client machine prevents the error notification dialog from appearing.
Solution
u
Verify that your vCenter Server and vSphere Web Client instances are not constrained by insufficient
system resources.
For hardware requirements, see vSphere Installation and Setup.
