VMware ESXi Update Version ESXi 8.0 Update 3g - ISO Build 24859861

VMware ESXi 8.0 Update 3g (ISO Build 24859861) delivers critical bug fixes and security updates, plus updated VMware Tools and microcode. It also includes the security-only ESXi 8.0 U3sg - 24853260 image.

• Security-only image ESXi 8.0 U3sg - 24853260 is included alongside the general security-and-bugfix image.
• Security bulletin ESXi_8.0.3-0.76.24853260 updates core ESXi, install/upgrade, and VMware Tools components.
• Security hardening related to ESXi host lockdown reporting and RSA/FIPS signature requirements is noted in previous-release issues.

• Fixes vSAN, storage, networking, vMotion, and host stability issues, including no-lock errors, VM boot failures, purple screens, and service crashes.
• Resolves NVMe over TCP connection drops and Intel VMD namespace enumeration failures.
• Fixes ClusterStore memory, DNS, and TLS 1.3 persistence issues.
• Addresses vGPU, passthrough, SR-IOV, and PCI device handling problems.
• Fixes hostd, rsyslogd, vpxd, vvold, and VMX failures that could disrupt management or VM operations.

• Adds VMX configuration option pciPassthru.exposeAtomicOps for AMD GPU passthrough workloads.
• Expands vGPU device group selection to 16 GPUs.
• Bundles VMware Tools 12.5.3 for 64-bit Windows, 12.4.7 for 32-bit Windows, and 10.3.26 for Linux.
• Includes updated AMD and Intel microcode for supported CPUs.

• Known issues from previous releases remain listed, including DPU, networking, storage, and vSphere Lifecycle Manager limitations.
• Some operations may still require workarounds, such as vSAN vMotion timeouts on Pure VASA providers and RSA signatures with keys smaller than 2048 bits.

• Host reboot and VM migration or shutdown are required for the ESXi image and most bundled VIB updates.
• The ESXi and esx-update bulletins are dependent on each other; Broadcom recommends including both in one host patch baseline or using the rollup bulletin.
• For ESXi 8.0 Update 3g, Broadcom directs admins to download patches from the Broadcom Support Portal.
• If you do not update to ESXi 8.0 Update 3g, the Intel VMD driver can be updated separately to version 3.0.0.1010-13.
• Quick Boot support depends on vendor compatibility lists referenced in the release notes.
