The following event may be noted in the main ESXi syslog: sfcb-dcim: doLoadProvider: dlopen(/usr/lib/cim/libcmpiTunnelProvider.so) failed, dlerror: libcmpiCppImpl.so.0: cannot open shared object file: No such file or directory ESXi Embedded Host Client is not accessible.Host disconnects from vCenter as soon as you start one of the above tasks.Tasks failing/timing-out on the host such as vMotion, snapshots, maintenance-mode, vm-power-on.The following symptoms may occur once a Dell server is upgraded to VMware ESXi 6.7 Update 3 if Dell OpenManage Server Administrator (OMSA) 9.3.0 is also installed: Note that also if it seems a NIC driver issue, it isn’t! The reason is different. There was a thread on Spiceworks about this behavior, but finally has been confirmed also by DellEMC with this page. VMs performance are not affected, but if you have vSAN this can be a huge problem not only in managebility but also in system stability, because vCenter will notice several issues (including time screw between vCenter and hosts). The vCenter become very slow and some basic operations, including vMotion are very very slow (also more than 100 times!). If you have tried to apply the VMware vSphere 6.7 Update 3 patch on a DellEMC PowerEdge server, you may have some kind of performance issues.
