This makes it easy for VI Admins to provision Virtual Private Clouds (VPCs), which can then be used to deploy vSphere Kubernetes Service (VKS) workloads using either vCenter Server \[…\] ## [Quick Tip: Selective ESX Host Patching in VCF 9.1](https://williamlam.com/2026/08/quick-tip-selective-esx-host-patching-in-vcf-9-1.html) _2026-08-10 · William Lam · WilliamLam.com_ Prior to VMware Cloud Foundation (VCF) 9.1, users could choose whether to apply an ESX update across all or a selected set of vSphere Clusters, but there was no additional granularity for selecting specific ESX hosts within a cluster. This has been a frequently requested capability, especially for excluding specific ESX hosts from an update \[…\] ## [Playing with Zero Touch Provisioning (ZTP) in vSphere 9.1 using an ASUS NUC](https://williamlam.com/2026/08/playing-with-zero-touch-provisioning-ztp-in-vsphere-9-1-using-an-asus-nuc.html) _2026-08-07 · William Lam · WilliamLam.com_ Introduced in VMware vSphere Foundation (VVF) and VMware Cloud Foundation (VCF) 9.1, Zero Touch Provisioning (ZTP) is the next evolution of Auto Deploy. Like Auto Deploy, it automates both ESX installation and host configuration. Instead of relying on the traditional PXE/TFTP boot process and Host Profiles, ZTP uses modern UEFI HTTP Boot along with vSphere \[…\] ## [Quick Tip: Automating ESX System Resource Pool Workaround Prior to 8.0 Update 3g](https://williamlam.com/2026/08/quick-tip-automating-esx-system-resource-pool-workaround-prior-to-8-0-update-3g.html) _2026-08-06 · William Lam · WilliamLam.com_ For users running ESX 8.0 Update 3 releases prior to Update 3g, applying patches may result in a pre-check failure with a SHA-1 signature error due to memory exhaustion, as outlined in KB 433124. The knowledge base article also describes a resolution that involves increasing the memory limit for one of the ESX system resource \[…\] ## [Quick Tip: Automating PAK Upload & Installation for VCF Operations](https://williamlam.com/2026/08/quick-tip-automating-pak-upload-installation-for-vcf-operations.html) _2026-08-05 · William Lam · WilliamLam.com_ While testing an update workflow, I needed to update VCF Operations directly, which can be performed through the /admin UI and by uploading and then installing the PAK file. Although the process itself is straightforward, the two-step workflow and the waiting between each step make it feel longer than the actual update. I figured there \[…\] ## [Password, Certificate & Backup Management UI/API for VMware vSphere Foundation (VVF) 9.1](https://williamlam.com/2026/08/password-certificate-backup-management-ui-api-for-vmware-vsphere-foundation-vvf-9-1.html) _2026-08-03 · William Lam · WilliamLam.com_ When it comes to VMware Cloud Foundation (VCF) capabilities such as the new unified Fleet Management, it is important to distinguish between the deployment type and the deployment entitlement. Deployment Type VMware vSphere Foundation (VVF) VMware Cloud Foundation (VCF) Deployment Entitlement VVF VCF Although related, these are two distinct concepts, and conflating them can lead \[…\] ## [Quick Tip: Reducing High CPU Utilization on NSX due to slow Entropy from AMD Zen4/5 CPUs](https://williamlam.com/2026/07/quick-tip-reducing-high-cpu-utilization-on-nsx-due-to-slow-entropy-from-amd-zen4-5-cpus.html) _2026-07-31 · William Lam · WilliamLam.com_ AMD Zen4/Zen5 processors have been known to have slower entropy generation, which can lead to higher CPU utilization for workloads that depend on random number generation.
