VMware is virtual machine software that provides a virtualized set of hardware (a video adapter, a network adapter, and hard disk adapters) to the guest operating system. VMware virtual machines become highly portable between computers, because every host looks nearly identical to the guest. In practice, a system administrator can pause operations on a virtual machine guest, move or copy that guest to another physical computer, and there resume execution exactly at the point of suspension. VMware's enterprise software hypervisors for servers, VMware ESX and VMware ESXi are bare-metal embedded Hypervisors that run directly on server hardware without requiring an additional underlying operating system.

so i've done this before in 2008 R2, but it's been a while...

i want to have a HA file server (migrating off an old netapp) using windows 2016
i have gone through the vmware article as a refresher and i think i know how to do this in this environment; just wanted to see if anyone has any thoughts or suggestions on my plan

i have 2 dell r430 servers with 4 1gb and 2 10gb connections running all my windows and linux guests
the 2 10gb connections go to a 10gb switch with a pure san
for the 1gb ports, 2 are used for guests and management traffic; 1 for dmz and 1 for vMotion
was planning to put 1 node on one host and the second node on the other host (vmware 6.0 standard so no drs rules to setup)
create 2 thin volumes on my pure san; 1 for quorum, 1 for file server data then add them to the 2 windows guests as physical compatible rdm disks
create a new vlan over the first 2 interfaces for private heartbeat network (no free physical ports)

does that generally sound right or am i missing something?
What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Serveral years ago, I transfered all of my users and computers from one windows 2003 domain to a new windows 2003 domain. Ever since the transfer I have had issues joining any ESX server to my domain. I do not believe it is an ESX issue, but an issue with my active directory. My PDC is now running Windows 2012 and the issue persists. I have exhausted every avenue I can think of to find why I cannot join the domain. I install 2012 as a virtual machine and created a test domain. I was able to join the ESX server on the first try without issue. I have compared my Default Domain Policy, Default Domain Controller Policy, Local Security Policy and AD permissions to the fresh install and they are the same.
I'm trying to replace the stock certificate that vCenter uses for the web console with a local MS CA certificate so errors don't get thrown about the browsers not trusting the cert.  I have found KBs and attempted to create a cert request with the vSphere utility (vCenter is on Windows Server), then process it on a MS CA (with custom template for this vSphere cert) and then tried to install it via the vSphere utility.  It takes forever and rolls back.  I just have some questions on the fields I enter when I create the request:

It asks for Name in the first part.  Is that just an arbitrary name that doesn't matter?  Or should it be specifically the plain name of the MS server?  Or the FQDN?  Or what?

There is a part where it looks like it assumes you are using VMware based CA, and it asks for the FQDN of the VMCA.  Since I am not using a VMCA, but rather a MS CA, for this field would I enter the FQDN of the MS CA or just the name of the vCenter server?

It looks like when I try to apply the cert, it shuts down all the vCenter services multiple times?  Does replacing this cert affect anything else other than the Web-based management console?   I don't want to screw anything up by doing this.
Hi, folks

I have few questions regarding VMware ESXi 6.5 and vCenter. I have VMware vSphere Essentials Plus license, two ESXi hosts PowerEdge R730 and shared DELL EMC storage. I implemented cluster and HA between them. I tested them and they are working properly.

Next, I have one physical server IBM x3300 M4 with VMware 6.0 with two virtual machines on own storage. My plan is to migrate virtual machines to shared storage and add IBM to cluster.

Can I add IBM server to vCenter because it is not the same hardware configuration as Dell servers?
Do I need to move virtual machines to shared storage, so HA can work? HA can not work if virtual machines will stay on IBM server?
Which method or tool you are recommending me to migrate virtual machines from IBM to Dell?

Thank you
HI ,

I have some quoestions in regards to the subject

1- is there any important feature in enterprise edition in terms of high availability that is not availble in standard edition and we should look at before selecting which edition to buy?
2-will Round Robin be free with standard edition ? can it protect against server power faliure (cluster scinario )or FC cable unplug ?
3- what could EMC power path for VE  give more value comparing to round Robin
4- what the best practice for implening HA on vmware
We recently installed a new vCenter 6.5 windows 2016 server and are looking to put our Trend Antivirus client on the server.  Does anyone know the recommended file/directory exclusions for Antivirus on a vCenter 6.5 server ?
I tried a few google searches to no avail.  If I have to open a VMware ticket I will but was hoping for a quick answer.

When trying to increase the CPU its only allowing me to add 1CPU and 1 Socket, if I increase the CPU it then gives me 2 CPU etc

What I want is 1 Socket 4xvCPUs

I need to know hardware information of a remote Dell PowerEdge R510.
I can access to this host through vSphere (VMware version: 4.1)
For example, I see 4 GB RAM (total), but I don't know if it's a single memory module or two.
Similarly, I see "Dell Serial Attached SCSI Disk" - capacity 227.25 GB, but I don't know if it is a single disk or a raid volume (and in case, what kind of RAID).
I need this to evaluate how can I upgrade hardware resources (maximum RAM and storage space), and which ESXi version could I install.
Thank you!

p.s. obviously, I have no iDRAC access.
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.
Hi Experts,

I have 2 Cisco ASAv 9.8 VM’s – Setup as transparent firewalls in bridge mode
Once active ASA moves between primary and secondary all traffic stops on VLAN10
ASAv is learning correctly the MAC address on the inside interface, but when failover occurs, this MAC goes to the outside interface.
Once ARP table is cleared traffic flows correctly again

Workaround is to hardcode the MAC address of each guest on vlan10 into the ASAv – But this is not ideal.

Any tips?

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

What's the quickest way to solve the issue ?

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 –
10x ESXi hosts – each configured with each own vSwitches no dvSwitches.
4 – HPE DL 360 G7 servers

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 –
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]

8 – HPE DL 380 G7 servers

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.

Hi Please see the attached picture. The Windows2008 is running as guest in vmware11.  Why WIndows 2008 size is very small in vmware workstation 11? I changed the host PC display with different resolution. but Widows2008 is still very small. I hope it can cover entire display. Thank you

Is it possible to upgrade from Vcenter 5 to 6.5 vcsa?
I am in the process of testing out vFlash cache on our of our test VM's as a POC. Most of our blades have 185GB SSD drives which is small but better than nothing. Here are my questions.

1) On of my servers I am hoping to use vFlash on is a DB which has a 300GB DB and high I/O. While the SSD cache is small would it still be worth setting up on the VM.

2) In the web client under the performance charts, what are the "ideal" number / ranges I should be aiming for to make sure the cache is tuned correctly?
VM Server failed , attached file is error I am receiving. Normally don't handle VM but our server guy is on vacation. Any suggestions? Thinking I should mount the ISO and do a repair but not really sure. Any suggestions would be appreciated.

one of our network guys changed the ISCSI software adapter on a host to the iscsi path of a san. how can it be changed back to the orginal.  It was origininaly something like iqn.1998-01.com.vmware:esx-79cf2f59  now its iqn.2011-06.com.sansdigital:sansdigital-000c28521:target2

I have disabled it and rebooted the host and attempted to add a new ISCSI software adapter but then it just re-adds the SANS digital. Since he has done this, now LUN's are presented.

I have Windows 10 VM I would like to clone, assign a new fix IP and windows license key.

What is the proper procedure?

In the process do I need I need to give a new computer name somehow before powering on?

Do I need to do any changes MAC address?

The VM currently is in a VMWare host.

The current Windows 10 VM is joined to a domain.

Any pointers for a smooth transition would be great.
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 ( - 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 (, 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?)...

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?
Hello, We have cluster of ESXi hosts that are members of our local domain, and all VMs on those ESXi hosts are also members of our local domain. I would like to make one of these VMs a member of the parent domain. is this possible?, i have heard from other people that it is not possible because the Esxi host the VM resides on is a member of the local domain, so the only other option would be to create a new VM in the parent domain, and replicate the data over?, Please assist, thanks in advance. we have 2 way trust between the 2 domains.
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 EE,

I have been getting this error for some VMs backups and replications. This is the following error message.

Can you guys help me decipher what it means, or where it could be going wrong? Any input is appreciated
