Good morning,

i have a problem with a Windows 2008 R2 SP1 Server virtual machine on ESX 5.5 Enviroment.

Every about 30 days thisserver brings out the following warnings related to VMware Tools, in this sequence,
every 5 minutes for about 2 hours:

 

#1 Event 1000 – VMWARE Tools - [ warning] [vmsvc:guestinfo] Failed to get nic info.

 

#2 Event 1000 – VMWARE Tools - [ warning] [vmsvc:vmsvc] Failed to get size of IP buffer.

 

#3 Event 2001 – Perdisk – [warning] Unable to read performance data for the Disk performance counters.

 

...until it becomes inaccessible!!!

It responds to the ping in a discontinuos way (not good)

 

Vmware tools service doesn’t run

I cannot manage the server

I must force to RESET it from Vsphere to access again .

I already re-installed once the VMware Tools, but the problem persists.

 

Would you have some suggestions for me about this issue?

 

Thanks a lot.

Alex

VmWare WorkStation 10.0.7 and Windows 10 Unable to Run VM

After Power on Virtual Machine, there is an error:

 

Unable to open kernel device "\\.\Global\vmx86": El sistema no puede encontrar el archivo especificado. Did you reboot after installing VMware Workstation?

 

Failed to initialize monitor device.


if I run the command "net start vmx86"  -> system error 5 / Access denied


It seems to be an error with execution privileges in W10, as I have to run VmWare as administrator since a few days.

May be this is due to OS upgrading from W8.1 to W10?


Does someone have an idea to suround this problem?

Thanks.

REST -> VCO

Hello, I'm trying to get a basic workflow kicked off via REST. I'm using the Firefox plugin RESTClient.

 

I was following this tutorial:

 

http://www.vcoteam.info/articles/learn-vco/265-how-to-run-a-perl-script-from-a-vcenter-orchestrator-workflow.html

 

and got the helloPerl.pl to work with REST, now I'm trying to change RAM on a VM...

 

Looking at this article, I believe has me pretty close:

 

https://communities.vmware.com/thread/515457?start=0&tstart=0

 

but still getting HTTP 400's on RESTClient... Here's my code:

 

{"parameters": 

[

{

"value": {"sdk-object": {"type":"VC:VirtualMachine", "id":"10.x.x.x/vm-name123"}},

"type": "VC:VirtualMachine", 

"name": "vm",

"scope": "local"

},

 

{

"value":{"number":{"value": “2048”}},

"type": "number",

"name": “memory”,

"scope": "local"

}

]}

 

My inputs in the xml displayed for the workflow are:

 

<parameter description="The VM to change" type="VC:VirtualMachine" name="vm"/>

<parameter description="New memory value" type="number" name="memory"/>

 

Any ideas?

 

thanks,

vRO workflow token can't get it's complex type attributes by invoking method WorkflowToken.getAttributes()

I have a workflow with a complex type attribute, default value was null for the attribute,  I want to run a script task to print current workflow token's attribute values by invoking method WorkflowToken.getAttributes(). Don't say to bind attribute with input/output parameter of script task than use the attribute directly, My objective is to create a generic action to do that thing. My script is:

var token = workflow;
System.debug(token);
if(token == null)
{    throw "No workflow token found";
}


System.debug("startDate: " + token.startDate);


var attributes = token.getAttributes();
if(attributes == null || attributes.keys.length == 0)
{
    throw "No attribute found for current workflow.";
}
System.debug("found " + attributes.keys.length + " attributes from current workflow.");


var keys = attributes.keys;
for (var i in keys) {
    var curKey = keys[i];    var curValue = attributes.get(curKey);   System.debug("attribute key: " + curKey + " attribute value: " + curValue);
}    System.debug("attribute key: " + curKey + " attribute value: " + curValue);
}

 

When I don't set value for the complex type attribute.

ComplexTypeNoValue.png

I could retrieve the attributes and get and null value of the complex type attribute.

Log.png

But once I set value of the complex attribute.

ComplexTypeWithValue.png

I got error when running the script task.

ErrorLog.png

I have tried many kinds of complex type, still get same error,I suspect if there's defect on vRO to retrieve complex type attributes from workflow token, or is there anything I missed? Can someone help me?

Poor disk performance in virtual machines

January 26, 2016, 8:07 am

Hi,

 

I have an VMware ESXi 5.1 update 2 infrastructure. It consists of five hosts in a cluster.

 

I have attached a fiber channel storage array to the hosts.

 

I have shown a LUN to the hosts.

 

I have created two windows 2012 R2 VM's, and put them in separate hosts.

 

I have attached the LUN to the virtual machines as a shared raw mapped phisical disk. I have created a MSCS file server cluster with those two Windows 2012 R2 servers and the shared storage.

 

I have installed IOmeter in one of the virtual machines.

 

I also have two Windows 2003. They are phisical machines. There is a file server cluster installed on them. Another fiber channel storage array is connected to them, to provide the shared space needed for the cluster.

I have installed IOMeter in one Windows 2003.

 

The array disk used for ESXi scenario, is at least, twice faster in performance than the used for Windows 2003 phisical scenario.

 

I run the standard tests in both WIndows 2003 and Windows 2012: 4 KB, 100% Read, 100% sequential. 4 KB 75% Read, 100% sequential. 4 KB, 50% Read, 100% sequential. 4KB, 25% Read, 100% sequential. 4KB, 0% Read, 100% sequential.

 

The results are suprising, at least I think so: all the measurements (I/Os per second, Total MB per second, Average I/Os response time, Maximun I/Os response time and % CPU utilization) are between twice and four times better in the Windows 2003 scenario. I mean, for example, in any of the tests, if the I/O's per second are 1200 in Windows 2012 machine, in the Windows 2003 machine is 4000.

 

Since the array attached to the ESX hosts is supposed to give twice much better performance than the attached to Windows 2003 phisical machines, I guess there is something not well configured, or something not optimized in the ESX host o Virtual Machine configuration. But I can't imagine what can it be.

 

I need help to improve the disk performance of these VM's.

I am seeing an issue with Windows Server 2008 R2 and wonder if anyone has any idea's?  At random the ping response will report "General Failure" when pinging a remote host.

The host is running ESX 5.5 U3.

VMWare Tools is loaded in the guest and the guest uses the VMXNET3 adaptor.

Other VM's on the same ESX host do not have this issue.

If I run 2 ping windows to the same destination IP they do not report the issue at the same time.

The general failure can happen to another guest VM running on the same ESX host.

 

Thanks!

Adding the Embedded vRO 7 to vCenter

I don't really see any documentation on the embedded vRO in the vRealize 7 documentation....it seems like in the past you had to go do something to add it as an extension to vCenter and then do the steps to configure it within vRA.  (logging into the VRO appliance, running some integration commands etc)..(i could totally be remembering that wrong).

 

Can anyone jot down the basic gist of steps needed for a fresh install of vRA to just get it to the point that you can configure say the vCenter endpoint for VRO and it have access? Or is that all that's required? I noticed the service for the control center is stopped by default...trying to comb through the documentation to find where it tells me to turn it on...no luck so far....i feel like the orchestrator integration is something that is poorly documented and explained due to there being several different ways it is used.  It's very confusing trying to understand if I'm supposed to be going by VRO documentation to configure it, or by VRA documentation or both..

Endpoint Ops agent without using admin credentials

Hey folks,

 

I want to deploy the endpoint ops agent to a few of our hosts which are running vCenter services (PSC boxes, vCenters, Web Clients etc). However, I don't want to use my admin credentials to connect the ep-ops agent to the vROPs cluster. Does anyone know what permissions I need to assign to a new local user to allow it to send data via the endpoint ops agent to the vROPs server?

 

I've tried assigning the AgentManager role to my test user and giving it full access to all objects but the agent can't connect.

 

Any ideas?

Hi All,

 

In this article we take a look into how can we set LDAP site affinity for VMware Identity Manager (vIDM) and VMware Identity Appliance (IDA) , especially when used as Identity Provider by vRealize Automation (vRA). We will look into native vIDM options that let us accomplish this as well as how to achieve this using F5 Big-IP Local Traffic Manager (LTM).

critical swap usage alert of Host

I am getting critical swap usage alert in one of the monitoring tool called nagios.

 

1) However when I went to the host from vCenter and checked the memory utilization from the cluster, the respective host memory utilization is only 66%

Also I went to performance tab of a host, when i selected memory, it shows a 1 min high spike and suddenly it went down.

My question is how do I identify, which VM is using more swap on this Host or what is the cause of  that high spike?


2) From ESXi command line, esxtop "m" output shows the below


SWAP  /MB:   123    curr,   122 rclmtgt:                 0.00 r/s,   0.00 w/s


which means it is using 123 MB swap and reclaim memory is 0.


My query is, when I can see it is showing 66% utilization of Memory, then why it is using swap? and I am not sure, how do I avoid to such situation in future?


Can anybody please, I have searched and didn't found anything relevant.

automating/simplifying maintenance mode of resources

We regularly do maintenance on some resources that are monitored by vrealize ops. In these circumstances I usually login to the GUI go to the environment overview, search for the relevant resources which all start with a specific 3 char prefix and put them in maintenance mode.

 

I was wondering if there was any way for me to make this easier to manage, ideally i'd like to run a script which is supplied with the 3 char prefix and that would put all resources that begin with that in to maintenance mode.

Is there a way for me to do this via powercli or via the API (from a python script maybe)?

 

 

Thanks

CPU Ready - total or per-vCPU

February 1, 2016, 11:44 am

A quick question for you performance gurus out there.  When you're discussing CPU Ready values do you typically speak in per-vCPU values or total values (for vSMP VMs) for the VM?  Or is it simply a matter of clearly defining which you're using with both equally valid (after all, if you add the per-vCPU values you'll end up with the total).

 

VMware KBase article (VMware KB: Converting between CPU summation and CPU % ready values) seems to imply you'd just calculate the total for the VM.

 

TIA!
