[Solved] Unable to view VM Guest (Hyper-V)

Hi,

I am unable to view Virtual Machine from 2 Hosts Hyper-V and It's ok for all other Hyper-V (~30).

Host 1 (Normal)

Host 2 (No VM)

In the Troubleshooting Tool for both, I have :

in WMI : 

MAC Address 1 MAC
Windows NameSpace Present
Dell Server Agent NameSpace Present
IPMI NameSpace Present
Virtualization Present

and in SNMP :

MIB-II (System Name) name
MIB-II (MAC Address) MAC
Server Administrator (Version) 7.2.0
Storage Management (Agent Version) 4.2.0
Inventory Collector (Agent Version) 7.2.0

We use only SNMP and WMI in discovery range


So if someone has an idea, I'm interested.

Best Regards

Re: Unable to view VM Guest

Hmmm....anything special about the network?  Solid LAN?  Variable WAN?  

I wonder if you can just try WMI without SNMP to see if there is a difference.

This whitepaper (www.delltechcenter.com/ome) may have a bit of info on hyperv.

Re: Unable to view VM Guest

Hi than's to reply ,

All network than I manage are not local, they are remote (by VPN).

The only things different is the Forest (and domain) name is composed (a.b.c) and other forest (and domain)  name are in (d.e).

All domains that I manage are in independent forest (AD).

Discover without SNMP, not found Vm name's, we lose few informations (battery status, etc...)

I I had already looked the white paper posting...

Any other Idea ?

Best Regards.

Hmmm...I can't think of any other ideas at the moment.  Perhaps the support team can direct you in the right direction.  You can open a ticket by calling 800-945-3355.

Re: Unable to view VM Guest

I just found!!

All my servers are in French, and the search criteria for VM are in English, modifying the criteria it works.

Info for the changes I made:
Line 9835 of \Dell\SysMgt\Essentials\configuration\DataFormatterFiles\Insrtuctions\FormatInstructions.xml
change :

<variable name="PPA::Expression" type="PPA:Smiley Frustratedtring">(contains (KEY(31f854cd-8ec8-45c5-91a7-197a5be99948),"Virtual"))</variable>

To :

<variable name="PPA::Expression" type="PPA:Smiley Frustratedtring">(contains (KEY(31f854cd-8ec8-45c5-91a7-197a5be99948),"Virtual") || contains (KEY(31f854cd-8ec8-45c5-91a7-197a5be99948),"virtuel"))</variable>
and
Line 9856 (same file)
change :

<variable name="PPA::Expression" type="PPA:Smiley Frustratedtring">(contains (KEY(31f854cd-8ec8-45c5-91a7-197a5be99948),"Host"))</variable>
to :

<variable name="PPA::Expression" type="PPA:Smiley Frustratedtring">(contains (KEY(31f854cd-8ec8-45c5-91a7-197a5be99948),"Host") || contains (KEY(31f854cd-8ec8-45c5-91a7-197a5be99948),"informatique"))</variable>

It works for me.

If you can tell the issue to software developper to fix in futur version, that will help...

Thank you for everything.

Re: Unable to view VM Guest

Hi,

Very interesting indeed. Just a few things i wanted to understand,

  • Is your OME machine also in FRENCH?
  • What is different between the 2 HyperV Hosts which are not showing up the VMs and the other Hyper V Hosts ?

As you have mentioned, that all your Machines are in French, we would expect this issue for all the Hyper V Hosts. But it is not. It is happening only with two of them. This will help us in narrowing down the issue. 

Your help is appreciated.

Thanks

Re: Unable to view VM Guest

Hi,

  • the OME machine is also in FRENCH.
  • This info is wrong, I thinked other machine can retrieve information but that was cached information...
I think it's a windows Update on the OME machine that change the parameters, probably between February 8 and March 17 2013.

Thanks for the information. It was a lot of help.

It should help us in making sure we do not land up in such issues again.

RE: [Solved] Unable to view VM Guest (Hyper-V)

Hi from germany,

we have the same problem with our Hyper-V Virtual Machines. None of them is detected as Hyper-V VM, all are "not classified".

SNMP and WMI is working on the Hyper-V Hosts and on the guests. All of our servers are installed with german language as default.

I tried to make the changes in the FormatInstructions.xml, but I have problems finding the right string in germany language. Can anybody help me?

OME 2.2 was installed today, did not fix the problem.

Thanks, Daniel
