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.

Restart Management Agent on ESX.

Anyone to expalin the difference between running

/etc/init.d/hostd restart and / or /etc/init.d/vpxa restart

and this command: services.sh restart

Thank you

Port Group used for High Availability.

per this link:
https://docs.vmware.com/en/VMware-vSphere/6.5/com.vmware.vsphere.avail.doc/GUID-B1906BCD-E538-4FFF-AAE9-5403FE253F38.html

On ESXi hosts in the cluster, vSphere HA communications, by default, travel over VMkernel networks. With an ESXi host, if you want to use a network other than the one vCenter Server uses to communicate with the host for vSphere HA, you must explicitly enable the Management traffic check box.

Not sure which VMkernel Network they are referring to. I thought by default HA traffic flows with Management Traffic (it uses the same Vmkernel port).

Any help ?

Thank you

Heartbeat Datastore list Empty:

I have one shared datastore. In Vsphere HA, if I click on Heartbeat Datastore I see by default this option selected :
"Use datastores from the specified list and complement automatically if needed"

I am not sure why the above option is by default though it makes sense to me that the option below should be by default:
"Automatically selected datastores accessible from the Hosts"

I also do not see the Shared Datastore listed.

Any help ?

thank you

Backup Resource Pools

The only place where I see Resource Pool can be backed up is when you Try to Disable DRS.
I wonder if there is another way to backup the Resource Pool without disabling DRS ?

Remove Snapshot with Command line:

I am trying to remove snapshot using the command lines below.  Retrieving the VMID then Removing snapshots related to that VMID:

 vim-cmd vmsvc/getallvms

[root@unknown000c290ed7cb:/vmfs/volumes/5e52777e-3a92a27c-79e3-000c29b2122f/VM1]

however when I run the ls -lha  command I still see the snapshot there:

Open in new window


in the snapshot manager there is no Snapshot showing.

Any Help ?

Level of Application of Shares /Reservation

I know that Shares and Reservation can be applied at the individual VMs level , Resource Pools Level.
I am not sure if it can be at the Cluster level or other levels.

Any idea ?

Vmware Reservation vs Shares

If I understand when you have for instance 2 VMs :

VM1 = Memory Reservation : 3 GB ,  CPU : 1GHZ
VM2= Memory Reservation : 4 GB ,   CPU:  2GHZ

Now whatever Share you allocate to VM1 or VM2, it is not going to make any difference , since VM1 and VM2 will have Memory and CPU guaranteed as allocated above.

So how does the Share work in comparison to Reservation ?

Thank you

ESX Host Reclaiming of Resources.

I would like to know at  which stage  of Resources reduction that ESX starts reclaiming resources...
I have read about the ESX techniques to work around resources need such as  : Baloon driver, TPS, Swapping,Memory compression

so When does ESX start using those techniques , before it decides to vmotion some VMs to another ESX host ?

Thanks

Hi,

i got 2 vpshere hosts. - running esxi 6.5.0 in HP Proliant servers.
host 1 running - 5 vm
host 2 running - 5 vm
both hosts are in HA mode.
so when host1 goes down, all 10 vm starts to run on host2 .  - this part is working good as expected.

but again when host1 comes up- the vm are not falling back again to host 1 from host2 .. -- how do i make it to work ? ? ? currently i had to manually move vm from host2 to host1.

Inflate Thin Provisioned Disk:

I have tried to inflate thin provisioned disk, but I got error:

"Unable to access file [Shared-Datastore] VM1/VM1_2.vmdk since it is locked "

So, is this possible only when the VM is powered off ? is inflating thin provisioned disk will male it Think provisioned disk ?

Thank you

VMEM file.



A VMEM file is a backup of the virtual machine’s paging file. It will only appear if the virtual machine is running, or if it has crashed.

I have linux VM running, but I do not see the VMEM file. is this just for Windows VMs ?

Vmware VMXF file

articles on the web define VMXF file as it  is  for VMware configuration file for virtual machines in a team.

What do they mean by VMs in a team ? is it VApps, or DRS VM Groups ? or what ?

Could you upgrade to ESXi 6.5 from 5.5 by vMotioning a VM from a 5.5 cluster on to a 6.5 cluster?
I'm at a shop where they're still on 5.5 so without support and they're running into problem after
problem with the normal upgrade path. I wondered if they setup a separate cluster of 6.5 (to
later be upgraded to 6.7) if there's any way to vMotion to the new desired environment.

Deleted Snapshots

If I have one or many snapshots of a VM, then I delete them all, will this keep the first snapshot on the Datastore and rename it "Consolidate Helper" ?

When does this "Consolidate Helper" file comes into the game ?

Thank you

Or possibly create a dummy extent in order to mount datastore.

One of two LUNs within a datastore was possibly deleted thus offlined the datastore. I need unmount and remount in order to recovery what's left by either creating a dummy extent or some other method.

understanding -delta.vmdk file

If I understand single -delta.vmdk file cannot exceed the size of the original -flat.vmdk file.

So, in the case  we leave a VM running on a snapshot, then  the -delta.vmdk file will keep growing till it reaches the size of -flat.vmdk file, then what will happen ?

Thank you

Within vCenter storage devices, I get a list of NetApp LUNs attached with their LUN ID.

One LUN shows Lost Communication and the datastore shows inaccessible.  I looked at the LUN ID on the NetApp storage but can't find any such name or LUN ID.

Is there another way I can find the vCenter LUN/Datastore on the NetApp storage so I can remap it with the correct LUN ID?

Thanks in advance.

Files that Make up VM

The snapshots below show a VM files when it is Powered and when it is Powered Off:

Powered On
a
Powered Off
p
- I would like to know how to get to open the files and read them. Probably some of them are in binary format:

- Regarding log files, sometimes a powered on VM will show : vmware.log and the next one is vmware-1.log, but sometimes , if you power it off and power it back on ,it will show vmware.log and the next one is vmware-2.log
Not sure why ?

-VSWP files I see there are 2 of them :
VM<Name>-xxxxxxxxxxx.vswp  and vmx-VM<Name>-xxxxxxxxxxxx-vswp
what is the difference?

- I see 2 vmx files:
VM<Name>.vmx  and VM<Name>.vmx''
what is the difference ?

- There is also VM<Name>.vmx.lck  : this looks like a locked configuration file, but I am not sure why it is locked ?

Thank you

I have a file server with 15 virtual disks attached all with the same size. I'm trying to remove 1 disk from vCenter but their disk numbers don't match up. i.e. disk 8 on the OS side could be disk 2 within vCenter.

DRS Time Interval

If I understand DRS runs every 5 minutes by default.
If the Migration Threshold is set to Aggressive , will DRS still run every 5 minutes ?

Also, where can the threshold be modified ?

Thanks
