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.

VM Host CPU over subscription, if a VM host has 24 logical processors and has say 40 vcpu configured would you consider that oversubscribed? I'm not sure anyone does 1-1 right? this host is in a cluster and DRS enabled.

CPU Cores : 12 CPUs x 2.00 GHz
Sockets : 2
Cores per Socket : 6
Logical Processors : 24
Hyperthreading : Active

On ESXI 6.5 a VM has the error:
There is no more space for virtual disk 'abcd-02.vmdk'. You might be able to continue this session by freeing disk space on the relevant volume, and clicking Retry. Click Cancel to terminate this session.

How do I solve this issue?

Hi Expert,

I would like to start learning on Vmware Sphere as most jobs require nowaday, like to check if anyone here the installing guide or video? Also does it need an extra pc to host it? Sorry that I am a desktop guy and only have VMware workstation experience.

Appreciate if any expert can advise me on.

Thanks!

Dear Experts

I have never seen this before. I have VM running W2012 R2 standard,¨

My NIC works normally when its address is received from DHCP.

When I assign this IP as static IP, it stops working.

Any idea why?

Thanks

We noticed that we can't open a remote console for a deployed VM from VRA web interface, we get the below error:

"Cannot connect to remote console. Verify that the machine is powered on and connected to the network."

The VMs are powered On, on Vcenter side the VMs look healthy.

This is what i have tried so far:

Ping from Host to vcenter where the VRA VM resides:
	[root@host:~] ping vcenter
	PING vcenter (10.93.104.30): 56 data bytes
	64 bytes from 10.93.104.30: icmp_seq=0 ttl=64 time=0.186 ms
	64 bytes from 10.93.104.30: icmp_seq=1 ttl=64 time=0.282 ms
64 bytes from 10.93.104.30: icmp_seq=2 ttl=64 time=0.343 ms

	3 packets transmitted, 3 packets received, 0% packet loss

Dear Expersts,

I need to understand licensing of VMware vCenter, I have two host VMware Esxi, First host have 7 VMs and second have 2 for fail over scenario. I want to understand how we licensed VMware ESXi and VMs that would running on it is also required to licensed??

I would like to confirm the following.

1) If a VM has 8 vCPU's the hosts vNUMA architecture is exposed to the VM if hot add is not enabled correct?
2) If you create a host / VM affinity rule to pin a group a VM's to host, If another host were to fail, would other VM's be able to use the host in the short term or would they be blocked from doing so?

We need to load balance two Windows 2016 Web servers that are VMWare Guests and we are using DFS.  In a previous post an Expert said not to use Windows Load Balancing, and suggested using Zen or a hardware load balancer.  
I'm asking again for the best way to setup load balancing for these web servers and please note we are using DFS.

What's the problems with using Windows Load Balancing and VMWare?
What should we be aware of when using web servers with DFS?

Thank you.

Hi, I have a cluster ESXi 6.0 with 9 nodes.
I noticed very bad performances on different VMs on my infrastructure.
According to resources utilization on entire cluster, I would exclude RAM / CPU issue.
I suspect there is some issue on storage side (we use PowerEdge MD3200 / 3800) through iSCSI.
I ran esxtop on some hosts, occasionally I noticed very high DAVG / KAVG values.
My question is: what would you do next?
Through esxtop I can find the "affected" lun.. isn't there a more efficient way to identify the VM (or VMs) that are causing performance issues?
Thank you

Helloooo

I have Vcenter with 3 hosts. I wonder if there is a way to have a copy of the configuration for  each
 host . The idea is to have this configuration file so if I format one of the hosts, I will always know the host configurations and just upload the configuration file to the that formated host .( I am using VMware ESXi5.).

Thank you....

Experts out there, I have a question on VMware datastore, hope someone will shed light on it. VSphere client shows a value for "storage usage" is 40 GB and the vmdk file size is less than 40GB. My understanding is that storage usage is included vmdk with some other files (vms,swap, etc). Is there any equation for that extra space usage? like 5% overhead etc.

Access ESX host DCUI Remotely

I would like to know how to access ESX host DCUI Remotely.

Our license subscription is about to expire. Would there be a technological reason to purchase a 1 year renewal vs a 3 year? The 3 year offers a small savings.

Probably a fairly "classic" issue but I have surprisingly not found definitive info about it online.

What is the best practice managing hardware RAID controllers on ESX Hosts ? Ideally, we would like to be able to "reach out" to the controller from a Windows guest VM but if not possible at the very least have some management capability (expand RAID, check array consistency) from ESXCLI.

How should we go about it ? In our specific and immediate case ESX6.5 with Intel RMS25CB080 controller.

HI all (Andrew), I was looking for a way to migrate a server from one ESXi server to another incrementally, I think.  

So I have a server that is like 2 T on a VMware server, I want to image it over, then be able to migrate it to another VMWare server, then be able to just migrate the changes over.  

Like if it's going to take a long time I can do it, then when we have a small window get people off the server, then zap over the changed files, shut off the old server boot up the new one and done.

I was trying to figure it out in Veeam, but got stuck.

Thanks all.

I'm having problems with VCSA.  My question is can I just delete the VCSA Appliance and redeploy without having other issues?

I am new to VMWARE..
In ESXi 6.5, I have a SSD Datastore (500 GB) that is giving a Data usage warning (free space low) .
The Server installed on it only uses 80GB, whereas the Virtual disks are 400 GB.
why all this difference and how to restore unused space.

We have vmware version 6 and using desktop client. All are good for now. I am going to have Windows 10 PC.
What is the best way to manage vcenter?
I guess desktop client is not supported on windows 10.

My vsphere web client all of a sudden no longer works with chrome. I Have the URL white listed in the chrome settings under flash and I have the latest version of Flash installed. Trying to access my vcenter but can't.

Greetings,
I need to reboot the connection server as well as the security server in our VMware View environment. There are active sessions. As I understand it, users will be disconnected but their VMs will continue to run on the host. Please confirm that this is the case.

Is there a specific order in which I should reboot the servers? Information regarding any other caveats in regard to rebooting the view servers welcomed.

Thanks a lot

Aloha,

I have a ESX 6.7U2 host booting from a 16gb flash drive. I am getting an error that the drive is full - space error message
However if I go into Putty and look at the drive (I believe the last one listed) - putty listing of driveI see neither a 16gb drive nor a full drive.

Any help is appreciated,
                                             Bill

Hi,

I have a Windows 2016 VM of which screen resolution is really bad (RDP from Windows 10).
VMWare tools are installed, no clue what else could be going on.

Please advise.

I need a good explanation/walk through for mitigating l1tf vulnerability on a 3 node esx cluster.

Documentation online is confusing and some of the horror stories I've been reading for people who didn't follow it correctly are irking me.

Pointing out any pitfalls would be helpful also!

Thanks in advance!
