Note: This post addresses and (hopefully) fixes the cause of the issue found here: vVols Endpoint - Failed to establish connection on ESXi host Recently, one of my customers was trying to refresh the CA store on newly built ESXi 6.7 U3 hosts under a freshly upgraded vCenter Server 6.7 U3 instance. When the admin tried refresh the CA store, they were getting this error message in the vSphere Client:
My customer has successfully rolled out VMware vSphere Virtual Volumes (or “vVols”) in their environment. They’re loving the simplicity of storage management in vSphere, but were a little stuck when they added a pair of newly installed ESXi hosts to their environment. The hosts were not mounting the vVols datastore as expected meaning hosts could not run VMs backed by vVols. All existing hosts were OK. To start, they dug in to the logs at /var/log/vvold.
Just recently a few colleagues of mine were attempting to generate new private keys with a 4096 bit size but they were seeing shocking performance from all of their Linux VMs. They were seeing key generation taking up to 15 minutes while smashing away at the keyboard to generate entropy. It wasn’t a resource issue, the VMs were sized appropriately and showed no signs of stress. They asked me if they could throw a “Chaos Key” USB device into each of the ESXi hosts to generate more entropy to reduce the time it takes, but I knew that wasn’t required (like I was going to let that happen).
