VMM NIghtmare

The VMs keep on changing to unknown even after updating to VMM 2.1 .
It seems that no one have been able to get VMM running correctly .

I thought the problems were gone after some days that our VM were correctly displayed .
All of a sudden today they reversed to "unknown" .

I tried all the things I could find in this forum but still got the problem .

I wonder if someone from HP can spell some knowledge on this ...

Thanks

Re: VMM NIghtmare

The possible problem could be, the communication between the SIM and the VM Host is not getting completed. But we have not seen this issue very often. SIM5.1 has a better way of handling this situation. I dont know what version of SIM you are running. If SIM upgrade is not an option for you, please log a support call with HP, we will engage the engineering team after having collected the details of the problem.

Re: VMM NIghtmare

I'm running SIM5.0 SP5 build C.05.00.02.00
VMM 2.1 .

The CMS have no problem communicating with WM hosts .

If I open the System Page of one of them and expand the "virtual machines "node I can see all the VM guests .

Another issue is that VM guest's OS , displayed in the VM Host's system page , is sometimes discovered as WIndows Server 2003 and sometimes as Microsoft(R) Windows(R) Server 2003, Standard Edition

Thanks

Re: VMM NIghtmare

SMH displaying the right information would mean that there is no problem with VMM. If you have an option to upgrade SIM to 5.1, I would definitely recommend you to upgrade. We definitely know that we are handling the WEBEM communication from VM host to SIM in a better way in 5.1. Otherwise please log a call with support with screen dumps and all the log files.

Re: VMM NIghtmare

You're talking about SIM 5.1 but the last released verion is 5.0 Sp5 which is the one I'm running .
I checked the HP SIM web site but couldn't find any 5.1

At the time I couldn't open an incident because we have no support and the 90-day support has expired before we had the chance to test the product in production

Re: VMM NIghtmare

5.1 is in beta..not sure if you have access to the beta channel. Please try the following:

1) Re identify the the VM hosta for which the corresponding VMs are showing unknown.
2) If you get an error during identification, restart the WMI and WMI MAPPER service on CMS(SIM server)

Re: VMM NIghtmare

Hi ,
we have no access to beta programs , in any case I wouldn't try a beta version in a customer's production environment .

I tried several time re-identifying the vm guests which appears as unknown .
I got no errors but the guest still appears as unknown

Thanks

Re: VMM NIghtmare

You will have to check the following verifications.
1. The VM guest IP addresses are pingable from CMS.

2. Make sure Under Options/Protocol Settings/WMI Mapper Proxy, the IP or name of the CMS is listed.

3. Please check system page of CMS and make sure WEB is listed under â Management Protocolsâ in the Product Description Table in the same.

4. WMI/WMI service must be running on the VM Guest.

If all the above verifications are positive and you still see the problem, try the following:
1) Restart the WMI services on the CMS.
2) If the above does not work, uninstall the WMI wrapper and install again.

Re: VMM NIghtmare

From what I observe, the problem seems to be with the WBEM proxy or the WMI provider.

So as an alternative, I would suggest that you install SNMP service on the VM guest and provide the proper community read string.

Think this should help.

Re: VMM NIghtmare

u may also want to verify that the global credentials configured in SIM does match with the account settings(userid/pass) on teh VMs

Re: VMM NIghtmare

Pal Pal :
The guests are all configured the same with SNMP already enabled and configured .

Ranganath
I set the global setting for WMI/WEBEM with a domain user which is a domain admin too so is by default member of local administrators group.

I recheck the settings but I did it lot of times by now

As update :
Today I noticed that a few of the VM are shown correctly as VM hosted-by server.
As , I said , they are all configured the same it's still difficult to me to understand how VMM works ( or doesn't work )

Re: VMM NIghtmare

Stefano,
This particular problem is not new. you can find a similar query in this forum. The problem is not with the VMM. The WEBEM protocol that SIM uses to discover the VMs is where the problem lies. We have in the past that WEBEM service on windows goes unresponsive/slow in some cases. In such cases SIM would not be able to identify the type of the VMs. That is the reason why I have been suggesting to try various options to fix the WEBEM communication. There is a fix for this in SIM5.1.Until then this is the work around to fix the problem.

Thanks

Re: VMM NIghtmare

Try the following (it worked for me)

On you VM install this
http://h18023.www1.hp.com/support/files/server/us/download/21071.html

Make sure ports 5989 and 5988 are open between your SIM server and you VM (and VM host)

Login to sim and select the VM you just installed the tool on. Go to Tools and Links and select System protocol settings.

Under WBEM settings select use this value and enter port 5989 put in a user name with local admin rights (just for this test) and enter the password. Verify that all SNMP setting are correct on the VM and on the SIM server and hit OK.

Run an identification task against the Vm and it should populate with all the info.

If that doesn't work there are some more drastic steps that you can try but try that for now.

Re: VMM NIghtmare

Stefano,
Mine is more stable now. But I did have to clear out the nodesecurity.xml file.
I stopped HPSIM, renamed the file and then restarted HPSIM and let it create a new one.

I then re-subscribed the HPSIM Server to the wbem events and then enabled wbem globally but with no credentials.
I then used the mxnodesecurity cli to recreate the required server specific wbem entries for each of the servers that use wbem.

This has proved quite reliable so far.

I've found that whenever I have Global Credentials entered various wbem problems occur, not all to do with VMM.
