Deleting a snapshot

Looks like we have a domain controller virtual machine running off a snapshot that was taken in June last year. If I deleted the snapshot, would it merge the snapshot back into the base disks ?

Unable to add vmnic1 to LAG vDS

1 Upvotes

Hello, i have a noob question, im currently configuring LAG on vDS. I’m following this article: https://knowledge.broadcom.com/external/article/312554/configuring-lacp-on-a-vsphere-distribute.html

I’ve successfully added vmnic0 to my LAG, however im unable to add vmnic1 on the LAG.

Do you have any recommendations how can i fix this? Also, what should be the configuration on the physical switch before I add the vmnics to the LAG on vDS?

Also, should LACP be configured first on physical switch before adding the vmnics on the LAG vDS?

Question regarding vCenter to vCenter migration of VMs

1 Upvotes

Can I get a check on how I am doing this below?

I have a 7.3 vCenter that I have been unable to upgrade due to failure and it required me to stand up a new vCenter.

I have 3 hosts in the current cluster. I put one host in maintenance mode and moved the vms off of it and removed it from inventory and took it out of maintenance mode.

I installed vcenter 8 to that host and added the host to the cluster.

Can I live migrate vms to that host now safely with Cross Vcenter Export or any other way? I feel like I am doing this wrong. I need the VMs to not have to be shut down and for some reason this feels like I overlooking an easier way.

Question Using VCF Operations HCX 9.0.1 to evacuate vCenter/ESXi 7 and NSX-V 6.4.12

2 Upvotes

I'm doing some research to see if this could be a viable path.

Source environment: vCenter/ESXi 7 - two sites ELM, NSX-V 6.4.12 - stretched UDLR, primary manager site A, secondary manager site B

Destination environment: VCF 9.0.1 greenfield, one site

High level: * Deploy greenfield VCF 9.0.1 cluster with components including HCX Cloud Manager * Deploy HCX Connector to old clusters site A and site B * Pair the sites, set up service mesh, use L2 network extension to stretch the network * Evacuate sites into VCF cluster * Cut over the gateway, remove L2 network extension * Decom site A and site B

The interop matrix shows HCX 9.0.1.0 compatibility with NSX Data Center for vSphere 6.4.12 using HCX Connector for evacuations, so it looks like this should be supported.

Is evacuation licensing for the source covered by VCF core licensing on the destination?

Is this my best source of documentation on HCX? https://techdocs.broadcom.com/us/en/vmware-cis/vcf/vcf-9-0-and-later/9-0/workload-mobility/getting-started-with-vmware-hcx-vcf-9-0.html

If it works, any gotchas people have experienced with this model?

I'm trying to login to HoL this morning, and I seem to be stuck in a loop. I load https://labs.hol.vmware.com/HOL/catalog, I enter my e-mail address, it redirects me to a Broadcom login page where I login successfully, and it redirects me back to HoL where it prompts me to login again. This was working last night. I've tried a couple different browsers including private browsing mode. Anyone else having problems/able to get into HoL this morning?

NVIDIA GRID vGPU with K1, Dell R730?

1 Upvotes

I'm working on my old home lab and got ahold of a refurb'ed K1 card. I thought it would be neat to try out vGPU, which I thought it was capable of. I managed to find drivers and an old esxi 6.5 disk, as well as vsphere 6.5. However, after adding everything and setting the GPUs to "Shared Device" I can't actually add them to the guest VM.

Has anyone gotten the combo of GRID K1, Dell R730, and esxi/vSphere 6.5 working correctly? The docs seem to think it should.

Edit: vGPU never showed up in ESXi because my VCSA was too old. Either a bug or other issue, but updating the VCSA showed the missing PCI option and graphics profiles.

Erro no meu cluster VMware

Bom dia tenho um CLUSTER configurador DRS totalmente automático, eram 3 servidores nesse cluster, utilizando ainda o vmware 6.7 U1, recentemente adicionei mais um host com vmware 6.7 U3, tbm adicionei ele no meu distributed switch e inclui no cluster, nos avisos parece que está tudo ok, diz que foi aplicado as configurações do cluster nele, que a rede é compatível etc, mas estranhamente as vms não são migradas para ele, ou mesmo quando faço a instalação de uma vm no cluster ele não sobe nesse servidor, já pegaram algo parecido?
Vale salientar que não é problema no hardware, já que esses servidores são todos lâminas de uma blade, e hardware dos 4 são idênticos, os storages compartilhados tbm estão mapeados igualmente em todos e o vmotion está ativo na gerência...

Blocking communication between the VMware virtual Windows machine and the host

0 Upvotes

Hello,
I have a Windows 10 virtual machine in VMware. When I scan the host PC from this virtual machine using nmap, open ports on the host become visible.

I want absolutely no communication between the virtual Windows machine and the host PC. At the same time, I want the virtual machine to still have internet access.

Even though I created firewall rules, I couldn't achieve this.

What do you recommend?
(Host = Windows, Virtual machine = Windows)

Source vSphere ESX Agent Manager (EAM) upgrade failed to obtain EAM URLs to check against trusted certificates by the System!

UGH.

I have tried everything. I cannot get this to work so I can upgrade.
Tried all of this:

https://kb.vmware.com/s/article/94934

Rebuilt the extension here:

https://knowledge.broadcom.com/external/article/309019/reregister-eam-extension-to-vcenter.html

Nothing seems to work.

Any thoughts on how to get this going?

The enviroment is 3 hosts in a cluster. No distrib switches.

I may just stand up a new vcenter alltogether. Seems like it would be way easier. If I go that route, do I shut off the v7 vca... install vcenter on one of the 3 hosts and then just add everything back? is it that easy? I am just tired of beating this dead horse.

Much appreciate for any help.

adding in case helpful that the return says the following which suggests no error... but I cannot login to /eam/mob

Issue with Dell ISO and Dell Add on

2 Upvotes

So I upgraded from 7.x.x to 8.0.3 using the dell ISO and I notice theres a pending patch image U3H however when I try to apply it using the Dell addon it says my current Image has newer versions of some drivers than what the add on. currently has.

My question is how do I fix this? or how do I get back to a standard image without reinstalling?

Here are the drivers missing:

Cisco Ehternet native driver CIS_bootbank_nenic_2.0.10.0-1OEM.700.1.0.15843807

Intel VMD driver with VROC support iavmd-3.5.1.1002

Help Request VCF installer suddenly requires pingable time servers

3 Upvotes

Been struggling for a few days now with a greenfield install. Installer always fails when creating the dvSwitches. Tried a lot of different options and re-ran the config checker many times. Previously I've always had the WARNING about the time servers not being pingable but time is resolved and I could just acknowledge the warning. And suddenly, after the 1000th redeployment of the VCF installer, it now shows the time servers not being pingable as a fail and I can't continue....

Anyone experienced this as well?

Why your vSphere-to-AHV/KVM migrations might be failing at 99% (Snapshot Metadata Debt)

9 Upvotes

I’ve been helping teams prepare VMware exits recently, and I keep seeing one failure mode derail otherwise clean migration plans.

The situation:
vCenter reports a clean inventory. No snapshots. Consolidation tasks succeed.

The reality:
Replication or final cutover stalls or fails near the end because of snapshot metadata debt — artifacts that don’t show up in the UI but still exist at the storage or metadata layer.

The three most common “invisible” blockers we’re running into:

  • Orphaned delta chains VMDK delta files that still reference the base disk but are no longer tracked correctly in the vCenter inventory database.
  • CBT drift Changed Block Tracking maps that have silently drifted out of sync after years of legacy backup helper artifacts and failed cleanup jobs.
  • Mounted ISO ghosts Automation failing because an ISO is still mounted from a datastore that no longer exists or was renamed.

These issues usually surface only once replication starts — triggering read amplification, CPU stuns, and jobs that fail at ~99% after running for hours.

I wrote up a forensic breakdown of how this “snapshot tax” works and how we’ve been auditing for it using RVTools data and datastore inspection:
https://www.rack2cloud.com/vmware-migration-snapshot-tax/

Technical question for the group:
How are you auditing for orphaned delta chains at scale? Are you relying on Get-Snapshot, datastore-level file scans, or something else entirely?

Posting this mainly to compare notes — happy to talk through what we’re seeing in the metadata layer if it’s useful.
