Property VixCOM.Constants.VIX_PROPERTY_VM_POWER_STATE returning 1032 or 1096

[AutoTestGuru]

Hi there

Using Workstation 6.5 with VixCom 1.6.1.4558.

I am using the VixCom API via C# to automate a single VM as part of a larger Windows based automated testing framework.

The basic process involves powering on a VM, waiting for it to power up, waiting for VM tools to load and then waiting for an application to launch via the startup menu.

When the VM is shutdown (from inside it NOT using the VixCom but using something similar to PSShutdown), I then wait for it to power down, pause 5 seconds, and then power it back on again and this is repeated.

At different stages of the power on process, I poll for the current state using the following code snippet:-

========

UInt64 error = 0;

VixLibClass m_VixComlib = new VixLibClass();

error = ((VixCOM.IVixHandle)VirtualMachine).GetProperties(properyIDs, ref properties);

if (m_VixComlib.ErrorIndicatesFailure(error))

{

Console.writeline( "Failed to retrieve the properties of the VM");

return -1;

}

vmPowerState = (int)((object[])properties)[0]; // VixCOM.Constants.VIX_PROPERTY_VM_POWER_STATE

vmPathName = (string)((object[])properties)[1]; // VixCOM.Constants.VIX_PROPERTY_VM_VMX_PATHNAME

========

Now, during the VM power on stage, vmPowerState returns either 1032 or 1096 and I am unable to determine what power state the VM is in. Its clearly not one of the known states defined

in Vix.h but I am aware of the fact that it could be a combination of a few states but I have been unable to determine what these are.

Any help with this will be greatly appreciated.

I know AutoTestGuy in real life, and had a quick look into this.

The constants are bitmasks:

VIX_POWERSTATE_POWERING_OFF	0000000001
VIX_POWERSTATE_POWERED_OFF	0000000010
VIX_POWERSTATE_POWERING_ON	0000000100
VIX_POWERSTATE_POWERED_ON	0000001000
VIX_POWERSTATE_SUSPENDING	0000010000
VIX_POWERSTATE_SUSPENDED	0000100000
VIX_POWERSTATE_TOOLS_RUNNING	0001000000
VIX_POWERSTATE_RESETTING	0010000000
VIX_POWERSTATE_BLOCKED_ON_MSG	0100000000
VIX_POWERSTATE_PAUSED	1000000000
VIX_POWERSTATE_RESUMING	100000000000

You're getting 1032 and 1096 which are:

10000001000	VIX_POWERSTATE_POWERED_ON
10001001000	VIX_POWERSTATE_POWERED_ON + VIX_POWERSTATE_TOOLS_RUNNING

But theres another bit on (1024) which isn't explained by the constants. I'd be interested to know what that actually means.

In any case try AND the value you get back with the constant you'd like to check and make sure that matches your original constant.

Quick C# example - powerState is the return value from GetProperty:

int powerState = 1032;

if ((powerState & VixCOM.Constants.VIX_POWERSTATE_POWERED_ON) == VixCOM.Constants.VIX_POWERSTATE_POWERED_ON)

{

Console.WriteLine("Powered on");

}

else

{

Console.WriteLine("Not powered on");

}

if ((powerState & VixCOM.Constants.VIX_POWERSTATE_TOOLS_RUNNING) == VixCOM.Constants.VIX_POWERSTATE_TOOLS_RUNNING)

{

Console.WriteLine("Tools running");

}

else

{

Console.WriteLine("Tools not running");

}
