Initialize VMs in a vSphere private Cloud using Cloud-Init Cloud-Init Datasource for VMware GuestInfo is deprecated The Web is full of explanations, how to use „Cloud-Init Datasource for VMware GuestInfo“ but https://github.com/vmware-archive/cloud-init-vmware-guestinfo it is deprecated. It is now integrated natively into Cloud-Init Cloud-Init 21.3 has been released https://discourse.ubuntu.com/t/release-of-cloud-init-21-3/23857 which integrates this software. New name: „DatasourceVMware“ https://github.com/canonical/cloud-init/pull/953, readthedocs https://cloudinit.readthedocs.io/en/latest/topics/datasources/vmware.html, I’d expect it to be in the current Ubuntu 21.10 (Impish Indri) https://cloud-images.ubuntu.com/impish/current/ – the release notes for 21.10 don’t specify the exact version.

I prefer accessing VMs using SSH or RDP directly. Sometimes, the IP-Address of the VM isn’t reachable, or protocols for remoteaccess need to be disabled for security reasons. In these cases, if an IP-connection to the ESXi-Server is available this could be an option to use the ESXi hypervisor as VNC-Server to provide access to VM keyboard, video, mouse… Three VM advanced Configuration Parameters need to be set: „password“ is optional, but mRemoteNG as VNC-Client doesn’t work without password set.Read More →

This is not for general usage, but an „admin-Jumphost“-computer/vm which needs to get flash enabled from time to time and is never used for public internet browsing… There it might be an un-dogmatic solution to install the last Firefox 78.15 ESR Release. Find it here: https://ftp.mozilla.org/pub/firefox/releases/78.15.0esr/win64/de/ Disable Auto-Update That’s easy Firefox Settings => Update Settings => „Disable Automatic Updates“ Disable Update-Notification That’s harder – Firefox guys (think to) know better what’s good for their users and they don’t even provide an „about:config“-switch: fail! Add the following registry Key: Add the following 32-Bit DWORD with value set to and restart Firefox.Read More →

Don’t delete the content of „c:\windows\ccmcache\“ manually with the File-Explorer: it is managed by „Windows System Center Configuration Manager (SCCM)“.

While the „old“ SCAv1 built a virtual fence around all virtual processors („Intra VM Security Boundary“), SCAv2 lets processors of one virtual machine (VM) to run within a „common fence“ („Inter VM Security Boundary“) which balances security and performance for most workloads. See https://www.vmware.com/content/dam/digitalmarketing/vmware/en/pdf/techpaper/performance/scheduler-options-vsphere67u2-perf.pdf for performance analysis.
