DNS in NAT is not responsive.

June 14, 2018, 7:20 pm

Hi fellows! My first post here.

 

As you know, when you are using a NAT network connection, the host's virtual adapter (actually not the adapter itself, but some sort of a virtual l3 switch ending with XXX.XXX.XXX.2 IP address) is acting as a DNS server. Now, I have Ubuntu VM, which does get response from this DNS, but it is veeeery slow. Also, when I ping the DNS from Ubuntu, the response time varies a lot. So it is working, but very slowly.

 

Now. Win 8.1, Win 7 Pro and Win Server 2012 R2, never get names resolved. They DO ping the DNS server, but cannot load any page (I get the error "DNS server is not responding" and the small pc icon on the bottom right is always with an exclamation mark).

 

After a few hours of trying to find what the problem is there, I gave up and set the DNS manually to my Physical router (192.168.0.1). The default gateway stayed as it was before. Everything is working now. But, could you explain the silly guy, what was the issue with the Default DNS server? Why Ubuntu was struggling, and the Windows machines were not able to load any web content?

 

My specs:

 

Workstation 14 Pro

Windows 10 Education 64Bit (it is same as Enterprise.  We got all these OS machines for free from Microsoft).

 

Than you.

Has anyone implemented UAG with both Horizon and vIDM on the same appliance? Or when pairing, do each technology require separate UAG appliances?

OS Process list visibility

Hey guys,

 

We have VROPS installed with EPOPS agents running on Windows Server VMs and I would like to know if it's possible to get a list of running processes and their CPU/MEM usage %.

 

We basically want to be able to see which process is taking all the CPU or MEM without logging in the OS using VROPS.

 

I was told it's possible to target a certain process and see it's activity but not get the list of off all the running processes.

 

Thanks in advance!

Cannot start VM: "Cannot find a valid peer process to connect to"

Hi folks,

 

I´m running the Fusion Preview on macOS High Sierra Beta3 (17A315i).

 

Every time when I try to start a VM I get the following error:

 

Bildschirmfoto 2017-08-06 um 08.23.42.png

Fresh install of Fusion did not work.

 

I´ve also tried to create a fresh, blank VM but I get the same error. I cannot start anything.

 

Does anyone see the same behavior?

 

Thanks and BR/JO!

On VM side, what's the difference between 1. rebooting a vm and 2. shutting down a vm and power it on shortly after?

June 14, 2018, 1:44 pm

In the initial startup of a VM, there's some initialization going on before it fully powers on. I assume during a vm reboot, such things do not take place, right? I'm also curious if there are any other things (like CoW, mem cache, vcpu allocation) that are different between the two scenarios.

 

I'm hoping with this post someone can shed more light on this. Thank you

Sporadic disk latency alarms on shared F/C disk array

June 14, 2018, 2:05 pm
$

Hello everyone,

I'm seeing some strange disk latency alarms, and wanted to get some feedback on them.  Our environment includes an IBM blade chassis and a Dell blade chassis, each of which is connected to F/C switches in their respective chassis, then connecting to an EMC VNX5200 disk array.  The IBM chassis includes Cisco switches connecting at 4Gbps, and the Dell chassis includes Brocade switches connecting at 8 Gbps.  All hosts are running ESXi 6.0.

 

Most of the VMs running on the IBM chassis are contained in individual LUNs, with some exceptions.  The VMs on the Dell chassis are generally grouped into LUNs, with a given LUN containing up to 12 or 15 individual VMs.

 

Periodically, but with no consistency, one or two VMs running on the Dell server blades will report high disk latency.  The alarm condition is raised, then clears itself after a few seconds. I'd like to identify the root cause of this, as it happens sporadically throughout the entire day, though there is no pattern that I can see.  I might see it happen twice a day, or not at all.  Another aspect that puzzles me is that it usually only happens to a single VM at a time, even though that VM is just one of several sharing the same LUN.  Other VMs on that same LUN are unaffected, though I know they all have disk activity taking place.  At the time the alarms are raised, other VMS in other LUNs on the array show a status of normal, even though all LUNS are in the same performance pool, and they all share the same redundant F/C links to the disk array.

 

I would expect that if the disk array was experiencing some type of latency issue, all LUNs would be affected, and most VMs would report the same latency alarm, but that doesn't happen.  Most often, only a single VM alarm is raised, though I do see an occasional instance where a few VM alarms are raised.  A moment or two later, the alarms clear.

 

Does anyone have any thoughts they can share on this?  I don't expect that this is a common scenario, but if you've seen it, or if you have any suggestions on how to resolve it, I'd be very interested in hearing about them.  Thanks in advance for your insights on this!

VSphere reservations/limit changes requires reboot

Our operations team are advising us that while vSphere will allow you to set the reservations/limits on a running server and vSphere will reflect those changes,  the changes do not actually take effect until the server is restarted.

 

So effectively making the hot add ram or vcpu capabilities unusable if reservations/limits are in place on a VM.

Have any of you found this issue or ways to work around it? (We are on 6.5)

Any thoughts/insight most welcome.

 

thanks.

Hello there

 

I have experienced VCSA 6.5 during boot-up showing this error code

error: invalid magic number.

error: you need to load the kernel first

 

Press any key to continue...

 

I have a feeling this issue could be taking snapshot backup for this appliance.

 

Any idea how to fix this issue

VSA unable to Backup

vCenter 6.5

I am trying to use the backup process in VSA to FTP to my NAS device.

 

Keep getting error VMware-statsmonitor is not started

 

I ssh; to my VSA and issued this command service-control --start VMware-statsmonitor    then it went to StartPending

 

I need a backup because I made a terrible mistake the other day cleaning up my data store I accidentally delete the wrong folder.

It would not delete the folder because it has a lock on the files but it did delete some files from the folder.

If I shutdown the VSA I will loose it because the files will be deleted once the lock if freed

 

Can I build another VSA then delete the original one?

 

I can not even take a snapshot of the VSA  I get error Detected an invalid snapshot configuration.

 

Any ideas?

 

Thank you

 

Tom.

Can Update Manager upgrade the ESXi host it's running in as a VM?

August 31, 2014, 10:53 am

That's the question.  Here's some background.  We have been a completely virtualized environment for several years.  2 ESXi 5.5 hosts collocated at different data centers connected of course by a site-to-site VPN.  The VPN itself is provided by VMs and vCenter runs in a VM at one of the sites as will Update Manager if we go ahead with installing it. If the vCenter and/or VPN VMs are down we have a very cool backup method of accessing and managing ESXi and its console.   Some of you reading the rest of this will be tempted to suggest architecting our environment differently but we're very happy with the way it is thank you very much :-)  Appreciate all responses but really just answered in this specific question.

 

The reason we want Update Manager is really just to be able to easily update ESXi in the future without getting into the console and running commands, etc.  I realize from documentation and blogs on this subject that ESXi may need to go into maintenance mode and shut down VMs running on it (not a cluster so no migration) at which point ESXi will either lose connection to Update Manager (if the remote host) or shutdown Update Manager (if the local host).  So the question is,  is the upgrade process managed by Update Manager an atomic operation at this crucial point or a sequence of operations dependent on the continued connectivity and control of Update Manager.  Ddoes ESXi then perform the upgrade and reboot independently - which would be great - or is it going to just sit there in maintenance mode waiting for more instructions from the now disconnected/shutdown Update Manager.

 

Your answers are much appreciated.

"Session Expired, trying to renew" message when logging on to Identity Manager

After creating a 3 node cluster, users often receive a "Session Expired, trying to renew" message when logging on.  The message usually disappears after a few seconds, but for some users is remaining and preventing log on.  Will setting the service.numberOfLoadBalancers option resolve this?  It's listed as optional in the documentation.

Where exactly do internal users need to connect to...?

June 7, 2018, 10:52 am

Hi all,

 

I thought I had this one figured out but another doubt has clouded my understanding.

 

I understood that, if I had multiple IDM appliances installed in the DMZ (behind a Load balancer) and IDM Connectors installed in the internal network, then internal users would need to connect to the URL of the Load Balancer in the DMZ (they would need to connect to the IDM appliances in the DMZ and not the IDM Connectors).

 

Is that correct?

 

Or does the user actually need to connect to the IDM Connector and they will be redirected through the web socket without needing to connect directly to the IDM appliance?

I ask that because there is no Load balancer in the internal network for the IDM Connectors so the user would need one of 2 things I believe:

1. Connect to a single IDM Connector but then they would have problems if that appliance was down for whatever reason

2. Configure an internal DNS Round-Robin type of setup where the user could connect to a single URL and internally that URL would be related to multiple IDM Connectors?

 

Anyone can help me with my doubt please (where exactly does an internal user need to connect to be able to open the Workspace portal?)?

 

Regards

Mark

... Just to say that it works surprisingly well, in Fusion 10.1.2 (and probably also in 8.5.10): it's also rather snappy (on a 2013 MacBook Pro); and HiDPI works out of the box, after installing the Tools.

 

Only one major glitch: some persistent visual artifacts in the menu extras, in the Finder tabs and in Dashboard, both in normal and dark mode...
