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.

HI EE,

I am using Veeam Backup and Replication to perform some backups of some linux based VMS. Recently, I started getting this error below:

Getting VM info from vSphere
Error: DiskLib error: [16].No file exists for given path -- File open failed: Could not find the file --tr:Failed to start file downloading.
VMFS path: [LOCALSTORE] /vmfs/volumes/54c79103-71bdf1a2-4420-001f295aced9/Generic/generic.vmx].

so far I have deleted the VMs from the backup job and readded them, created new backup jobs, but I still get the same error message

Hello,

Is there something I can do when I receive this error (op operating system was loaded) in Hyper-V

HyperV.jpg
I do not know if the system I have imaged was UEFI or not. I also do not understand the SCSI disk term, since it is a regular SATA of which I created the VHD.

Hi Experts,

On VSphere 6 Web Client, I have removed a virtual machine from inventory, deleted the datastore it was on and have detached the storage device. But the storage device still shows in the device list.

How can I permanently remove the device, so that it no longer shows in VSphere?

The datastore is no longer needed and I want to delete the volume from the SAN once all records are removed from VSphere.

I'm trying to connect to vSphere and reboot a vm.

I can ping the ESXi host and I can connect to it via Power-Cli. If I try to connect via Vsphere client, it says

"THE REQUIRED CLIENT SUPPORT FILES NEED TO BE RETRIEVED FROM THE SERVER... CLICK RUN THE INSTALLER OR SAVE THE INSTALLER".

Whatever I click, I get the message "THE REQUIRED CLIENT SUPPORT FILES CANNOT BE RETRIVED FROM THE SERVER.....".

So if I connect via PowerCIi, I issue the command GET-VM VMNAME | RESTART-VMGUEST, I get an error CANNOT COMPLETE OPERATION BECAUSE VMWARE TOOLS IS NOT RUNNING IN THIS VIRTUAL MACHINE.

The VM at this moment is isolated and cannot connect to it.

What's the quickest way to solve the issue ?

Thanks!

The is using Veeam agent for Windows. The setup and configuration is straightforward, and the backup works perfectly. However, found that the retention policy doesn't work. Please see the configuration as attached. I use the default 14 days for retention. Besides this, the Active full backup is enabled too. However, the end result is, backup images of older than 14 days are still there. What's went wrong, and how to get this retention works?

Thanks in advance.

Hi People,

I’d like to consolidate the VCenter server in my two different Data Center into just one as Active / Passive to reduce the operational maintenance cost.

Data Center 1
Vcenter server: VMware VCSA v6.5b – 10.1.1.30
10x ESXi hosts – each configured with each own vSwitches no dvSwitches.
HA-Production-1
4 – HPE DL 360 G7 servers

HA-Production-2
6 – HPE DL 360 G9 servers

Data Center 2
Vcenter server:
Physical Windows Server 2008 R2 & SQL Server 2008 R2 Standard Edition.
VMware VCenter 5.5b – 192.168.17.136
14x ESXi hosts.

dvSwitch-PROD-NET [Production Corp network]
dvSwitch-VOIP-NET [Production Voice network]
dvSwitch-DMZ-NET [Production DMZ network]
dvSwitch-Test-NET [Testing Corp network]

HA-DRS-PROD-1
8 – HPE DL 380 G7 servers

HA-DRS-VOIP-PROD-1
6 – HPE DL 360 G9 servers

Can I consolidate the VCenter from Data Center 2 into Data Center 1 and then deploy the VCSA in Data Center 2 as Passive mode ?
So when there is any issue, I can just failover to the passive VCenter node.

What about the dVSwitch migration from Windows Server Vcenter into the VCSA, is there any downtime required ?

The current link is running on dark fiber with 35-40 ms response time as I tried to ping from one VCenter to another.

Any kind of help and suggestion would be greatly appreciated.

Thanks,

This is using 5 Xenserver 6.2. All the while, we were using Acronis backup and replication version 11.x. However, this is the outdated version and tends to fail the backup operations. The only way when the backup is failed, we have to uninstall, reboot the system, and then re-install the Acronis  from the scratch. Is kind of frustration. Our management decided not to upgrade to use the current Acronis version 12. In fact, we are out of budget to get any replacement.

I heard that using the Citrix Xenserver XE commands, we can automate the backup operations without down the VM. Please shed the light on how to get this done, and other alternative way.

Thank in advance.

We need to migrate about 60 VMs on 15TB of storage from one vCenter cluster to a new one. Both clusters will be on the same management / VM subnet (10.0.0.0/16 - latency < 1ms) - basically, we are just upgrading / replacing the hardware within the same physical datacenter because it is nearly five years old.

The old vCenter cluster consists of three hosts and a 3PAR SAN (7200). It is running vSphere 5.5 Standard.

The new vCenter cluster also will consist of three hosts and has a Nimble SAN (CS3000). It will run vSphere 6.5 (probably Enterprise Plus).

On each cluster, the SAN network (FC) is local to the cluster itself - so, one cluster cannot "see" the other cluster's SAN (each cluster has its own FC switches). The vMotion VMkernel network on the old cluster (192.168.100.0/24), however, could be made visible on the new cluster via vLAN (i.e. the new cluster could use that same subnet for its vMotion VMkernel, with three unique 192.168.100.x addresses).

What would be the easiest and best way to migrate VMs from the old cluster to the new? Ideally, we'd like to be able to storage-vmotion from the old to the new, but doubt that that would be possible (as the two clusters would not be able to see each others datastores - would they?)...

Br,
Hans

Running Vmware in VMware?

We have a physical machine that runs VMware and hosts a VM we use for SharePoint deployment testing. That machine is old and dying, and my employer's network czars are heavily pushing hosted VMs as a replacement for outdated physical servers. I was curious about whether it's possible to run VMware inside VMware, and if so, whether there are severe performance implications. We don't require extreme performance from this setup, since it's just used for SharePoint testing and the associated SQL Server is on a different box. My guess is that we can't just use the primary hosted VM for our testing because we'll want to roll back occasionally and otherwise have more control over it, and getting buy-in for that from the network folks is unlikely. Does anyone have any experience with this?

What are the different methods that VMware can communicate with VMs stored on a Storage Area Network (SAN)?

Is iSCSI usually the best method for doing this?

Hi All,

Can anyone here please let me know what do I need to do in order to successfully cutting over the Anti Spam solution from onPremise Linux VM into the Cloud Solution with no data loss or user email flow interruptions?

As at the moment on my Exchange 2013, the Send Connector Smarthosts listing the local IP address for the 2x Linux VMs.

Do I just change it to the Public IP address of the Cloud Anti-Spam provider ?

Note: My Public DNS server is running on my On-premise Windows Server 2008 R2 VMs.

Thanks,

Hi EE,

In my domain I have a Server 2012 R2 virtual machine that is our root CA. I have a subordinate CA on another machine. Recently the root CA decided not to boot. Went through different recovery methods to get the machine online, but failed. I have rebuilt the VM with the same name as the old server and mounted the original VM's HD to the new one. What steps do I need to recover the failed CA's information? This is a fairly new build for the original CA, so I didn't get a good/full backup before it failed. All articles I come across describe backing up the private key from the CA, registry, etc before decommissioning. I technically have all the data, just not in a backup form.

I have a VMWare ESX 3.5 server. It has one virtual machine on it, windows sever 2003, Two of the drives of the drives are damaged eg:-

[] /vmfs/volumes/4f43ac1e-8500a034-54f2-001372695ef7/New Virtual Machine/New Virtual Machine_3.vmdk)

As opposed to a healthy one:-

[datastore1] New Virtual Machine/New Virtual Machine_1.vmdk

Is there any way of trying to recover these?

We've had intermittent App-V publishing problems for a few weeks now, where if the client kicks off an App-V publishing refresh within the first 30 or so minutes after login, the publishing refresh would fail (even when manually running Sync-AppvPublishingServer from PowerShell), and then none of the apps launch.  After around 30 mins on an user session, the problem magically sorts itself out.

After much troubleshooting, it's become apparent that the problem seems to be due to the fact that the client is asking our local proxy server to find the publishing server (which is at http://ctxapp-v01.domain.local:82).  Now, for a start, the proxy server will block any attempts at port 82, so it gives a 403 error.  But that's not the point, the point is that it shouldn't even be trying to get to this via the proxy server at all, because I have the "bypass proxy server for local addresses" box ticked.  I've tried disabling the IE proxy altogether in Internet Options before kicking off the Sync-AppvPublishingServer command, but to no avail.  I've also tried to enable it, but explicitly add the App-V server address into the proxy exceptions list.  I've even tried setting the local system proxy to None using the command 'netsh winhttp reset proxy', but still no joy with anything.

I can ping/browse to the App-V server from the client machine no problem - it's even inside the same subnet.

Is there a hard-wired way to tell the App-V client to never try to go through the proxy …

Hi,

I went through the specs of a budget laptop from Acer   Acer Aspire E5-553-T4PT.

Does   Acer Aspire E5-553-T4PT support 2 DDR4 RAM slots where I can place two 8 GB DDR4 RAM.

Also, does the   Acer Aspire E5-553-T4PT laptop support wireless ac.

I read somewhere that the BIOS does not support virtualization.

Does the BIOS of   Acer Aspire E5-553-T4PT support 64-bit virtualization using VMware Workstation 12 and Virtualbox?

Please provide your valuable suggestions and if possible, please provide me some reference URLs about the Acer   Acer Aspire E5-553-T4PT specifications.

Thanks and Regards,
Sriram. K

I am having a probelm with using local usb printers redirected for RDP session. I install the usb printer on the WYSE thin client Win 7 Embedded. The printer works. I then login to the RDP VM using use local resources with RDP session. The redirected printer shows up in the list of printers in the Virtual Machine (Win 10 pro). When selected to print it does not and just gets an error.

I then tried to share the printer on the thin client. I can connect to the printer and install while in the RDP session. It all works fine but as soon as you restart the VM, Thin Client or just logout the printer stops connecting.

Any ideas on using local usb connected printers. While logged into the RDP VM session?

Hi and thanks for reading this,

I am trying to setup my little infra on a new ESXI server and I have some "basic" troubles. I am trying to have two VMs on an isolated network for testing purpose. What I did is creating a port group attached to a vSwitch and attaching each VMs to this port group. vSwitch image .

After assigning static IPs to each VM (with ip addr add dev eth0 X.X.X.X) I tried to ping and get some output from arpd but it's like each VM was connected to nothing...

First question: Is there a good guide to understand ESXI networking ?

Second question: Am I missing something ? (is it something to do with vNIC?) Does ESXI6.5 have something special to do that? As I am new to ESXI I'm a bit clueless for now.

Thanks for any answer,

I am investigating the use of TAPs in virtualization for capturing data from VMs.

I am interested in two methods.

Virtual Taps within the VMware using Network vSwitch (standard and distributed)
and
Physical TAP that would be connected to the ESXi Host or switch or both.

First, for virtual taps.

On a standard vSwitch on one ESXi host, I think that promiscuous mode will need to be set on a port group?  If I have a VM on vSwitch2 that is connected to ESXi nic2 and a VM on vSwitch3 connected to ESXi nic3, what is process to capture data from the VMs?

Distributed Switch,
If the Distributed Switch called d_vSwitch1 is set up for two ESXi Servers, ESXi-1 and ESXi-2, and VMs are on a Distributed Port Group called Data-A1, what is process to capture data from the VMs?

Second, for a physical tap

If I have this old nTap (pic attached), how can it be used to capture traffic data coming into ESXi-1 from ESXi-2?

Also, for another use case, instead of using a virtual tap, could I use the old nTap to capture traffic data between the VM on vSwitch2 that is connected to ESXi nic2 and a VM on vSwitch3 connected to ESXi nic3
