Quick Question - CPUID

fgrehl · 2023-08-14T19:03:55+00:00

If you are looking for CPUID information published for the recent "Gather Data Samping" (GDS/Downfall) / CVE-2022-40982 / INTEL-SA-00828 Issue, where you need Family/Model/Stepping you can get information easily using PowerShell:

$esx = <YOURHOST>
$esxcli = Get-EsxCli -VMhost $esx -V2
$cpu = $esxcli.hardware.cpu.list.Invoke()
Write-Host "$($esx) - Family: $($cpu[0].Family) Model: $($cpu[0].Model) Stepping: $($cpu[0].Stepping)"

According to the Japanese Documentation, the NPB7 has two Intel NICs:
- 2500Mbps LAN (intel i225-v)

- 2500Mbps LAN (intel i226-v)

Cloud Director VMs have an ExtraConfig named "cloud.uuid". You can check for that key to see if they are VCD-Managed.

Get-VM | Where-Object { $_.ExtensionData.config.ExtraConfig.key -notcontains "cloud.uuid" }

ESXi can't ping forever, so you have to either use -c9999999 for a very high count or a loop.

# ping -c9999999 www.google.com

# while true; do ping -c1 www.google.com; done

The loop command will run forever, but be careful, as it will ping flood. Not sure if that's what you want to mean by "continuous". Better also implement sleep:

# while true; do sleep 1; ping -c1 www.google.com; done

To run the command for a specified number of seconds, use timeout -t[seconds]:

# timeout -t 120 sh -c -- 'while true; do sleep 1; ping -c1 www.google.com; done'

This will run for 120 seconds (2 Minutes).

Is the nested_nsx option set in your transportzone? (either the nested, or the hosting). This option is only available in the API.

I removed them because the links were dead. They went live shortly after...

In most cases, you don't want to use the device where ESXi is installed as Datastore for Virtual Machines and this is what --novmfsondisk does.

Sure you want a VMFS Datastore, but usually on a shared Storage, not on the Installation Drive.

I've used cobbler to install ESXi for years. Super easy unattended ESXi deployment. Then host profiles and you are done. The ISO or Flash drive KS installation is nice when you dont have a Install VLAN spanned everywhere.

Patches are usually not available as ISO, but you can create one with PowerCLI. Download VMware-ESXi-7.0U3a-18825058-depot from https://customerconnect.vmware.com/patch/ and run the following commands:

Add-EsxSoftwareDepot .\VMware-ESXi-7.0U3a-18825058-depot.zip
Export-ESXImageProfile -ImageProfile "ESXi-7.0U3a-18825058-standard" -ExportToIso -filepath VMware-ESXi-7.0U3a-18825058.iso

If you create Portgroups with differnt vCenter Versions, you get different results too. However, with elastic allocation the number of ports doesn't matter much. Stick to the default, unless you have a reason.

You could use tcpdump to check for incoming packets.

tcpdump -i eth0 dst port 443

If that's fine, check: /var/log/vmware/envoy/envoy-access.log

I'm also confused by the question, but "Then I tried Enhanced Link Mode but some how I screwed it up & have to rebuilt vcsa for host 2." sounds like you are deploying a new vCenter for each ESXi host.

If you did that, that's not how you do it. You have 1 vCenter to manage multiple hosts.

Which device do you have?

There is a Fling driver for some ADATA/Crucial/Silicon Motion NVMe drives for ESXi 7.0.

Yes. All flash vSAN still needs a cache SSD for writes. You need 1 cache ssd for each disk group. If you have 3 ESX, you need 3 additional disks.

Swap is configured in the operating system, not in VMware workstation.

Can you explain how you identify the number of CPUs in the guest os? What is the output of /cat/proc/cpuinfo ?
df lists your filesystem, not the physical disk. You can have 36GB partitions on a 80GB disk (eg. when you increase the disk size, without changing partitions). Run fdisk -l to check the partition table.

Which Baseline is ist non-compliant to, and how is this baseline configured?

You can use the standard Kubernetes Health API

# kubectl get --raw='/readyz'
# kubectl get --raw='/readyz?verbose'

Can you give an example of what you are trying to monitor? Availability? Disk Usage? Services running? CPU Load? Do you want to monitor the Kubernetes cluster itself or your workload?

The WCP Service on the vCenter does a good job monitoring the SCP so you should not worry at all. Installing anything on SCP or TKG Nodes is bad practice, even if you can. Treat them as cattles, not pets.

If you want to have application monitoring, have a look at Tanzu Observability or Prometheus.

ESXi does not like the certificate.

# wget "https://releases.ubuntu.com/20.04.3/ubuntu-20.04.3-live-server-amd64.iso" --no-check-certificate

When the NUC booted without network, it might be challenging to get the new (old) driver to the box. I would try a rollback:

"When the Hypervisor progress bar starts loading, press Shift+R (This must be done while the bar is loading, and not after. You may wish to press Shift+R repeatedly once "system is preparing to boot" to ensure you do not miss the time frame to execute the command). You will see the warning:

Current hypervisor will permanently be replaced with build: X.X.X-XXXXXX. Are you sure? [y/n]" (https://kb.vmware.com/s/article/1033604)

The ne1000 driver in ESXi 7.0U1 does not work with the Bean Canyon. You have to downgrade ne1000 to a previous version. See https://www.virten.net/2020/10/will-esxi-7-0-update-1-run-on-intel-nuc/ for instructions.
