Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.

Dear Experts,

There is a confusing situation I installed a VM on hypervisor for some purpose . My colleague  did some mess with it. He copied  data on C drive more then VM's capacity and then machine was crashed. So he moved the machine on other drives of physical machine server. And now i  noticed the data of the VM machine with its installed softwares are scattered around all drives of the Phyisical machine and it causes wastage of space. How can I deal with it? Please suggest me some solution. or I should go for fresh installation.

Thanks in advanced

hello all


i registered a vmx file manually on VMware ESXi 5.1.0 Update 1 ( build-1065491 )

the registervm command output vm id 3, reported no issue, created the usual files including .vmxf and edited the .vmx as usual

listing the vms produces the message "Skipping invalid VM '3' " but lists other vms

powering on the vm produces "Power on failed" without a single hint

"vim-cmd vmsvc/destroy 3" does not output anything and exits with a 0 error code but does not destroy anything

the vm is listed as "Unknown" in the UI and no action is available


the same script used on esx6 with the same vm works without problem. i am unsure i ever tested that same script against 5.1. i was expecting this host to be on-par with the rest of the cluster.


questions

- how can i actually unregister/destroy that vm

- how can i debug what vmware does not like ?


thanks for your help

We have recently installed AppV Reporting to a new server and are receiving errors when submitting reports.

Using powershell we use the command:

Send-AppvClientReport -DeleteOnSuccess -URL http://sharedapps01:5558/ -Verbose

Open in new window


We get the error:

Send-AppvClientReport : No reporting data has been sent to the specified URL. Verify the URL and try again.
Operation attempted: Send reporting data to reporting server. 
AppV Error Code: 1300000013. 
Please consult AppV Client Event Log for more details.

    + FullyQualifiedErrorId : SendReportError,Microsoft.AppV.AppvClientPowerShell.SendAppvClientReport

Open in new window


The appv reporting database is hosted on a SQL 2016 AAG and the appv reporting server computer account has db_owner rights to the database.

Within the client machine event logs we get the error:

Reporting data cache could not be sent to Reporting Server. (rc = 0x9E900713-0x13).

Open in new window


There are no event logs logged on the server itself.

The followiong article describes our issue but does not appear to have a solution:
https://social.technet.microsoft.com/Forums/en-US/08dc2436-eee4-465a-a7b7-47329a65532a/appv-5-reporting-error-while-uploading-reporting-data?forum=mdopappv

The AppV reporting service seems to be a simple IIS website that accepts, processes and then  inserts the data into the database, it doesn't appear to be anything overly complex, but the lack of server side reports is making it difficult to identify what the issue is.

Any support would be much appreciated.

I have a VM network/distributed port group 192.168.21.x.1 which is tagged as VLAN 21

I have 2 servers in the VLAN 21 VM network. Both are able to resolve DNS address and access the internet (these 2 servers were added by someone else)

Recently I had to add a new server to the same VM network/Distributed port group and after adding it, the VM could not resolve DNS at all. If i move the server out of that network/port group into another one DNS resolution works again. DNS servers are listed and they are the correct DNS servers.

  • Can not resolve internal DNS server name but can ping internal DNS servers fine with no issues
  • Can reach/ping default gateway
  • Can ping servers/workstations on different subnets with no problem
  • Checked and windows firewall is not blocking DNS access
  • The server can ping internet addresses if I have the public IP. I can ping yahoo, google fine just fine
  • Tested with another server, same result.

I am at a lost right now to what it could be that is stopping DNS resolution when 2 other servers are fine.

Hello,

I am trying to expand a volume on a cluster of Windows 2016 VM's. The cluster contains 2 nodes and they are all running on top of vSphere. When I try to expand a hard disk in vSphere I receive the message below from the vcenter console:

The disk extend operation failed: The virtual disk requires a feature not supported by this program
Hot-extend is currently supported only for VMFS flat virtual disks without snapshots opened in persistent mode.


I also tried shutting down the Node1(active) and then expanding the vm disk. However, I receive a message stating there is a locked file:

The disk extend operation failed: Failed to lock the file

Although, this could be due to the clustered aspect of it. Can someone help me clear my webs and tell me if I am not following the proper procedures or if I am actually experiencing an issue within vmware while trying to expand the disk?

I am simply trying to expand the vmdk in vsphere and then go into the windows server and expand it using diskmgmt

Hi, we have recently created a Hyper-V server but after a few days of use we can no longer take backups. If we restart the VM the checkpoint still fail but if we restart the host they begin to work again. Is there a way of releasing whatever process is using the file so we can take checkpoints for backup again? I've attached a screenshot of the error.

Is there an easy way to find out what process is using the avhdx checkpoint file and can this be deleted to allow the checkpoint process to run. Also the VM does not show it has any checkpoints in the HyperV manager so assume these are created as part of a backup process.

We recently stepped into the light and virtualized our environment. I was told that doing a p2v on a domain controller was not recommended. I was wondering if that is the case? I have a physical 2008 R2 server that is a DC, NPS and a Certificate server which is used for my wireless environment using Radius which EE helped me to set up and configure and works great.. I would like to virtualize this if possible. We had an outside company do the virtualization. For the DC they created a couple of VMs and made them Domain Controllers and transferred over the FSMO roles from the physical to the virtual. It has been a few months now and everything is running fine. We still have three physical servers because of their AD roles. What can I do about those?

CEOs need to know what they should worry about
CEOs need to know what they should worry about

Nearly every week during the past few years has featured a headline about the latest data breach, malware attack, ransomware demand, or unrecoverable corporate data loss. Those stories are frequently followed by news that the CEOs at those companies were forced to resign.

Hi,

we use veeam for our backup solution in the datacenter. We backup our Hyper-v hosts to a veeam backup and replication server. This server is located in the same datacenter. After this backup we use cloud connect to send the data to another location.

Last week someone told me that the cloud connect solution is not so good as if the original backup i take is corrupt then the cloud connect copy is also corrupt.

He told me that we need to setup a second backup and replication server and then take a second backup with that server.

when i told veeam about this they told me to use the sure backup option. we have the enterprise license and this is included they told.

what are your ideas over this? What to do to make sure we take correct backups.

I'm trying to add a VM to a user in Exchange and I keep on getting this error.  We use 3CX as our VoIP system, in a VM, and Exchange is where the VM is stored.

Starting yesterday, when I try to add a VM to a user, I keep on getting this error. NO changes to my 3cx server or Exchange, so this is odd.

I checked my event logs app/system, and didn't find anything that would point to an issue.  
Also did a wireshark capture for 10 seconds on my exchange during the time I received the error, and still, I didn't see any issues in the wireshark that could be a problem.  
I looked on my 3cx system, in the logs, and nothing shows up there as an issue.

I don't think this would have anything to do with it, but my manager disabled TLS 1.0 on our exchange server to make it more secure, so I doubt that would have anything to do with it?

Not sure what else to do, any thoughts?

Installed
VMWare Client Integration Plugin v6.2 (For Internet Explorer 11 and Firefox Ver. 66)
and
VMWare Client Integration Pluginv6.0 (For Google Chrome Version 73.0.3683.103 (Official Build) (64-bit))
on a
Windows 7 Enterprise SP1 (64-bit) PC.

What Works
- ISO upload to VMWare vCloud Director Catalog works using Internet Explorer 11 only (does not work with Chrome and Firefox) on the PC.

Workaround in place - Console Content Access works for all the same VMs via a Windows Server 2008 R2 Standard Server from within the same environment (setup by someone else not contactable)
(This Server will be decommissioned soon - so need the console working on the PC before the server gets decommissioned)

What Does not work
– VMWare vCloud Director WebMKSConsole Content Access – for any VMs – using any Web Browser (IE, Firefox or Chrome)

Get the following screen – doesn’t matter whether the URL is DNS Name or via IP Address.

Troubleshooting done
-      Added DNS Name to local host file on PC (which made the ISO upload work)
-      Reinstalled VMWare Client Integration Plugin v6.2 , v6.0 and v5.6 after uninstalling, reinstalling and rebooting a number of times.
-      Added Firewall Exclusions on Local PC for all profiles (Domain, Private and Public)
-      Installed the Valid Certificate for FQDN in Automatically Selected Store and the Trusted Root Certificate Store.
-      Tried Troubleshooting described on various VMWare Website and Forums – some were unclear.

I have inherited a VDI deployment and I've tried researching half a day for a clear and concise way to do this.  I have some VMware Horizon 6 experience but I cannot find any documentation on increasing the persistent disk size on dedicated desktops.  Any assistance would be greatly appreciated.

I am trying to upload a file to a datastore and this is the error I get.  I have tried both solutions and it still does not work.  I have booted our vcenter appliance and tried from a single vm host and still no joy.  Running VMware 6.5

 - The operation failed for an undetermined reason. Typically this problem occurs due to certificates that the browser does not trust. If you are using self-signed or custom certificates, open the URL below in a new browser tab and accept the certificate, then retry the operation.

Hello,

as a reasonably inexperienced person with VMware, I have an issue with a VM. It is an SBS2011 server in production and the last few days there is an error in the event logs about the hard disk having a bad block. Since then our Veeam backups have failed with a CRC error. CHKDSK with no parameters (i.e. no attempt to fix anything) shows 8k in bad blocks.

I know chkdsk can be destructive to data, my worry is if I run it there is a very small possibility the VM will not boot afterwards - unlikely but that would be just me luck. To minimise downtime I was wondering if I could protect against this by taking a snapshot beforehand. If the VM gets broken by the chkdsk I could just revert to snapshot, would that be correct?

Thanks a lot.

Hi I am very new to virtualization especially on hardware front.
I have been given a task to mount IBM and DELL Rack based server and install esxi in it.

What I done until now is I have put the server on Rack and connected it to switches , and the done the cabling for HBA so that it goes to the FC switch.
I have attached an USB where I am planning to install esxi.

Can anyone please let me know what should I do to get the idrac console or imm console of the server on my laptop which also part of the same office network so that I could install esxi remotely.

After connecting to my switches I tried to access the imm or idrac from my laptop connected in same network using 192.x.x.x IP ( which I read from IBM website ) and I could not reach it.

Hello experts,

I have a 2 node Hyper-V 2012 Cluster using CSV that's been working fine for years.  Suddenly today, I'm unable to live migrate from node A to node B.  I can however, live migrate from node B to node A.  

On node A I see the following events for each guest VM when attempting a live migration:

Live migration of 'Virtual Machine machinerunningonNodeA' failed.

Virtual machine migration operation for 'machinerunningonNodeA' failed at migration destination 'Node B'. (Virtual machine ID 6F6C2D2D-97B6-4669-86D0-A72BB87E968A)

'machinerunningonNodeA' Failed to create Planned Virtual Machine at migration destination: General access denied error (0x80070005). (Virtual machine ID 6F6C2D2D-97B6-4669-86D0-A72BB87E968A)


Here's what I've tried to solve my issue:

-Validated Cluster
-Removed the guest VM role from the cluster and re-added it.
-Rebooted both nodes
-Tried to quick migrate from node A to node B.  It fails.
-Tried shutting down guest VMs and moving them to node B.  When I do that I can not start them on node B.  I get the following immediately upon moving:

Cluster resource 'Virtual Machine Configuration xxxxxx' of type 'Virtual Machine Configuration' in clustered role 'xxxxxx' failed. The error code was '0xb7' ('Cannot create a file when that file already exists.').

AND

'Virtual Machine Configuration xxxxxx' failed to register the virtual machine with the virtual machine management service.

PowerShell Script Request:  Identify and report zero session information on Citrix XenApp 6.5 Windows 2008 R2 HSD Server VMs. If possible reboot the zero session HSD Server VM.
It's a 24/7 client cannot take the VMS out of production. We usually do two VMs reboot at a time. At that time logins will disable and then reboot the VM.
However, was thinking of some script which could look for the VM that does not have a session and can reboot it.
 "If there is NO session on any one of the HSD VM, then take the VM OUT of production, then reboot and Bring it back into Production". ie Scheduled Reboot.

This is a SuSE 11 SP4 VMware virtual machine. Initially 1 virtual hard disk was allocated with 140 GB. However, the disk space is getting less, and we increase this virtual hard disk size with additional 50 GB. The SuSE disk layout is as follows,

# df -h
Filesystem                              Size  Used Avail Use% Mounted on
/dev/sda2                                38G   35G  2.1G  95% /
udev                                    7.8G  100K  7.8G   1% /dev
tmpfs                                   7.8G   76K  7.8G   1% /dev/shm
/dev/sda4                                50G   43G  4.4G  91% /opt/omd/sites/ssp/var
tmpfs                                   7.8G   29M  7.8G   1% /opt/omd/sites/ssp/tmp
/dev/sda3                                40G   34G  4.3G  89% /opt/repo

The partition that we intend to increase is /dev/sda2. On SuSE, we run "echo '- - -' > /sys/class/scsi_host/hostX/rescan"; replace X with 0, 1, and 2.

Now, if you type "fdisk -l", you manage to see additional 50 GB is added (as unpatitioned)
