There are a number of competing vendors (and industry watchers) waiting to capitalize on any weakness shown in the VMware stack and with the recent number of QA issues leading to a significant bugs popping up not abating, I wonder how much longer VMware can afford to continue to slip up before it genuinely hurts its standing.
The latest couple to watch out for have become common repeat offenders since the 5.5 release…problems with vMotion, Pathing leading to PDLs/APDs and CBT issues have seemed to be on repeat if you search through the VMwareKBs over the past twelve to eighteen months.

KB2144657 – ESXi 6 may not fail over correctly after encountering a PDL
As a Service Provider the CBT bugs are the most worrying because they fundamentally threaten the integrity of backup data which is not something that IT Operation staff or end users who’s data is put at risk should have to worry about. Veeam have done a great job circumventing the issue, though these issues are being fixed with drastic measures like full CBT resets…On a IaaS Platform where machines are not easily scheduled for downtime this is a massive issue.
To be fair the VMware team do a great job and keep everyone up to date with issues as they arise and are generally fixed in quick time…VMware can’t afford to have many more:
This is a known issue affecting ESXi 6.0.
Currently, there is no resolution.
Especially if they are repeat bugs!
