Meltdown and Spectre are critical vulnerabilities existing in several modern CPU: these hardware bugs allow programs to steal data which is currently processed on the computer. Meltdown and Spectre can affect personal computers, mobile devices, server and several cloud services.
Depending on the bug, the affected CPU are Intel processors (since 1995!), some AMD CPUs, and several ARM-based Samsung and Qualcomm system-on-chips used for mobile phones.

Reading Time: 3 minutesNow that the PSOD on vSphere 6.5 and 10 Gbps NICs issue is finally solved seems that vSphere 6.5 critical bugs are closed, but it’s not totally true.
During an upgrade from a vSphere 6.0, I’ve found a really strange iSCSI storage issues where all the VMs on the iSCSI datastore were so slow to become un-usable. First I was thinking about drivers or firmware, in the hosts and in the NIC (1 Gbps) or the firmware on the storage.
Reading Time: 2 minutesOn October 2017, I wrote a post about a possible issue with vSphere 6.5 and 10 Gbps NICs (mostly standard on new deployment). The final result was a PSOD (Purple Screen Of the Death) and no solution was available (yet).
VMware KB 2151749 describe this issue as related to possible upgrade at vSphere 6.5. But other customers have report the issue also on new deployment.
Veeam, one of the first vendor to found this issues (from their customers), reports that the issues is due to network-intensive activities such as backup over NBD or vMotion randomly triggering one. But seems that this bug can be triggerer not only from high network load, but also from creating vmkernel ports.
