Producent oprogramowania do wirtualizacji Vmware udostępnił najnowszą wersją dla rodziny 7.0 o numerze wersji 3n. Dzięki aktualizacji, zostały rozwiązane problemy z agregacją pakietów ruchu nakładkowego (Generic Network Virtualization Encapsulation ) wielu fizycznych adapterów sieciowych, które miały funkcję Hardware Large Receive Offload(LRO). Ponadto poprawiono błąd dotyczący maszyn wirtualnych podłączonych do przełącznika logicznego NSX. Nie były one poddawane migracji i pozostawały na hoście ESXi podczas ponownego uruchamiania hosta, przez co VNIC  maszyn wirtualnych mógł utracić łączność. Po więcej informacji, zapraszam do dalszej części materiału.

Rozwiązane problemy:

ESXi_7.0.3-0.95.21930508

This patch updates the esx-base VIB. Due to their dependency with the esx-base VIB, the following VIBs are updated with build number and patch version changes, but deliver no fixes: trx, esx-dvfilter-generic-fastpath, vdfs, esxio-combiner, cpu-microcode, esx-xserver, vsan, native-misc-drivers, vsanhealth, gc, bmcal and  crx. This patch resolves the following issues:

• PR 3192477: Many LRO-capable PNICs do not aggregate packets from overlay trafficMany physical networks adaptors (PNICs) that have the Hardware Large Receive Offload (LRO) capability might not aggregate packets from the Generic Network Virtualization Encapsulation (Geneve) overlay traffic.This issue is resolved in this release. The fix adds a software-based LRO functionality within the VMkernel that makes sure that if an LRO-capable PNIC does not aggregate packets from the Geneve overlay traffic, the VMkernel aggregates them instead. The change does not affect VLAN and VXLAN traffic.
• PR 3186367: If virtual machines connected to an NSX logical switch stay on an ESXi host during a host reboot, such VMs might lose connectivityIf virtual machines connected to an NSX logical switch are not migrated and remain on an ESXi host during a host reboot, the VNICs of such VMs might lose connectivity.This issue is resolved in this release.

esx-update_7.0.3-0.95.21930508

Due to their dependency with the esx-base VIB, the following VIBs are updated with build number and patch version changes, but deliver no fixes: loadesx and esx-update.
