the Sky is the Limit
VMware vRealize Log Insight is a priceless tool to analyze system logs of a virtual infrastructure. Setup is rather simple and has been covered in a blogpost on this site.
I will show the easy update procedure of an appliane 4.6.0 to version 4.6.1.
I recent times I frequently see vCenter server appliances (VCSA), whose root partitions ran out of free space. As a result services are unable to start after reboot. There are some tricks to free some space on root but on the long run you should increase the partition size.
Sounds simple – but it’s quite tricky and a bit dangerous. Don’t try this at home! 😉
Since vSphere 6.5 the HTML5 client (vSphere-Client) is an integral part of the environment and is geting updated with more and more features with every release of vCenter. It is to get rid of the infamous flash client (web-client) sooner or later.
In distributions below 6.5 there’s no HTML5 client included. But it is possible to get the functionality with a fling.
Microsoft’s monthly March 2018 rollup KB4088875 contains a patch KB4088878 which seems to have issues with Windows Server 2008 R2 VMs and VMXNET3 adapter. Applying the patch disconnects Windows Server 2008R2 VMs.
Yes, indeed! There used to be an old problem with Server 2008R2 VMs which had a VMXNET3 NIC. After restoring these VMs from backup, they’ve lost their static IP and instead switched to DHCP. The problem is known by VMware and there’s a corresponding KB1020078.
Microsoft released in a hotfix 433809 (KB2550978) to prevent the issue. But you had to switch to DHCP first before installing the hotfix and then revert to your static IP. I’ve published the procedure in 2013. This blogpost is in German but the procedure is simple:
It seems that Microsoft now has included that old hotfix into a montly rollup. At least the similarity is striking.
Those who had already applied the Hotfix in the past to their 2008R2 VMs, seem to be immune to the problem.
