------------------------------------------------------------------------------------ 📁 𝐌𝐚𝐢𝐧 𝐕𝐌 𝐅𝐢𝐥𝐞𝐬 – 𝐏𝐮𝐫𝐩𝐨𝐬𝐞 & 𝐁𝐞𝐧𝐞𝐟𝐢𝐭𝐬  1) .𝐯𝐦𝐱 – 𝐂𝐨𝐧𝐟𝐢𝐠𝐮𝐫𝐚𝐭𝐢𝐨𝐧 𝐅𝐢𝐥𝐞 𝐏𝐮𝐫𝐩𝐨𝐬𝐞: Stores all VM settings such as CPU, memory, network, and disk configuration. 𝐖𝐡𝐲 𝐢𝐭 𝐢𝐬 𝐮𝐬𝐞𝐝: This file tells the system 𝐡𝐨𝐰 𝐭𝐡𝐞 𝐕𝐌 𝐬𝐡𝐨𝐮𝐥𝐝 𝐛𝐞𝐡𝐚𝐯𝐞. 𝐁𝐞𝐧𝐞𝐟𝐢𝐭𝐬: * Enables VM power ON/OFF * Allows easy configuration changes * Helps in VM recovery and re-registration * Makes VM portable between systems 2) .𝐯𝐦𝐝𝐤 – 𝐕𝐢𝐫𝐭𝐮𝐚𝐥 𝐃𝐢𝐬𝐤 𝐅𝐢𝐥𝐞 𝐏𝐮𝐫𝐩𝐨𝐬𝐞: Stores OS, applications, and user data. 𝐖𝐡𝐲 𝐢𝐭 𝐢𝐬 𝐮𝐬𝐞𝐝: Acts as the 𝐯𝐢𝐫𝐭𝐮𝐚𝐥 𝐡𝐚𝐫𝐝 𝐝𝐢𝐬𝐤 of the machine. 𝐁𝐞𝐧𝐞𝐟𝐢𝐭𝐬: * Supports easy backup and restore * Allows storage expansion * Makes VM migration simple * Separates data from hardware 3) .𝐯𝐬𝐰𝐩 – 𝐒𝐰𝐚𝐩 𝐅𝐢𝐥𝐞 𝐏𝐮𝐫𝐩𝐨𝐬𝐞: Used for memory handling when RAM is insufficient. 𝐖𝐡𝐲 𝐢𝐭 𝐢𝐬 𝐮𝐬𝐞𝐝: Ensures the VM continues running even during memory pressure. 𝐁𝐞𝐧𝐞𝐟𝐢𝐭𝐬: * Prevents sudden VM failure * Improves system stability * Automatically managed by the system 4) .𝐧𝐯𝐫𝐚𝐦 – 𝐁𝐈𝐎𝐒 / 𝐄𝐅𝐈 𝐅𝐢𝐥𝐞 𝐏𝐮𝐫𝐩𝐨𝐬𝐞: Stores firmware-level settings like boot order. 𝐖𝐡𝐲 𝐢𝐭 𝐢𝐬 𝐮𝐬𝐞𝐝: Keeps startup configuration consistent. 𝐁𝐞𝐧𝐞𝐟𝐢𝐭𝐬: * Ensures reliable boot process * Maintains firmware settings across restarts 5) 𝐒𝐧𝐚𝐩𝐬𝐡𝐨𝐭 𝐅𝐢𝐥𝐞𝐬 (-𝐝𝐞𝐥𝐭𝐚.𝐯𝐦𝐝𝐤, .𝐯𝐦𝐬𝐧) 𝐏𝐮𝐫𝐩𝐨𝐬𝐞: Stores changes after a snapshot is taken. 𝐖𝐡𝐲 𝐢𝐭 𝐢𝐬 𝐮𝐬𝐞𝐝: Allows returning to a previous VM state. 𝐁𝐞𝐧𝐞𝐟𝐢𝐭𝐬: * Safe testing before updates * Quick rollback in case of issues * Reduces risk during changes 6) .𝐥𝐨𝐠 – 𝐋𝐨𝐠 𝐅𝐢𝐥𝐞𝐬 𝐏𝐮𝐫𝐩𝐨𝐬𝐞: Records VM activities and errors. 𝐖𝐡𝐲 𝐢𝐭 𝐢𝐬 𝐮𝐬𝐞𝐝: Helps understand what is happening inside the VM. 𝐁𝐞𝐧𝐞𝐟𝐢𝐭𝐬: * Easy problem identification * Faster issue resolution * Useful for audits and reviews 🌟 𝐎𝐯𝐞𝐫𝐚𝐥𝐥 𝐁𝐞𝐧𝐞𝐟𝐢𝐭𝐬 𝐨𝐟 𝐔𝐬𝐢𝐧𝐠 𝐌𝐮𝐥𝐭𝐢𝐩𝐥𝐞 𝐕𝐌 𝐅𝐢𝐥𝐞𝐬 Using separate files instead of a single file gives many advantages: ✔ Better organization ✔ Easier troubleshooting ✔ Flexible backup and restore ✔ Faster migration ✔ Improved fault isolation ✔ Strong disaster recovery support 🎯 𝐖𝐡𝐲 𝐕𝐌 𝐅𝐢𝐥𝐞𝐬 𝐀𝐫𝐞 𝐈𝐦𝐩𝐨𝐫𝐭𝐚𝐧𝐭 𝐢𝐧 𝐑𝐞𝐚𝐥 𝐋𝐢𝐟𝐞 * If one file has an issue, others can still remain safe * Data can be protected separately from configuration * VMs can be moved, copied, or restored easily * Systems become scalable and hardware-independent

Quick Guide to VCF Automation for VCD Administrators

  Quick Guide to VCF Automation for VCD Administrators VMware Cloud Foundation 9 (VCF 9) has been  released  and with it comes brand new Cloud Management Platform –  VCF Automation (VCFA)  which supercedes both Aria Automation and VMware Cloud Director (VCD). This blog post is intended for those people that know VCD quite well and want to understand how is VCFA similar or different to help them quickly orient in the new direction. It should be emphasized that VCFA is a new solution and not just rebranding of an old one. However it reuses a lot of components from its predecessors. The provider part of VCFA called Tenenat Manager is based on VCD code and the UI and APIs will be familiar to VCD admins, while the tenant part inherist a lot from Aria Automation and especially for VCD end-users will look brand new. Deployment and Architecture VCFA is generaly deployed from VCF Operations Fleet Management (former Aria Suite LCM embeded in VCF Ops. Fleet Management...

Step-by-Step Explanation of Ballooning, Compression & Swapping in VMware

 🔹 Step-by-Step Explanation of Ballooning, Compression & Swapping in VMware ⸻ 1️⃣ Memory Ballooning (vmmemctl) Ballooning is the first memory reclamation technique used when ESXi detects memory pressure. ➤ Step-by-Step: How Ballooning Works  1. VMware Tools installs the balloon driver (vmmemctl) inside the guest OS.  2. ESXi detects low free memory on the host.  3. ESXi inflates the balloon in selected VMs.  4. Balloon driver occupies guest memory, making the OS think RAM is full.  5. Guest OS frees idle / unused pages (because it believes memory is needed).  6. ESXi reclaims those freed pages and makes them available to other VMs. Why Ballooning Happens?  • Host free memory is very low.  • ESXi wants the VM to release unused pages before resorting to swapping. Example  • Host memory: 64 GB  • VMs used: 62 GB  • Free: 2 GB → ESXi triggers ballooning  • VM1 (8 GB RAM): Balloon inflates to 2 GB → OS frees 2 GB → ESXi re...

  Issue with Aria Automation Custom form Multi Value Picker and Data Grid https://knowledge.broadcom.com/external/article?articleNumber=345960 Products VMware Aria Suite Issue/Introduction Symptoms: Getting  error " Expected Type String but was Object ", w hen trying to use Complex Types in MultiValue Picker on the Aria for Automation Custom Form. Environment VMware vRealize Automation 8.x Cause This issue has been identified where the problem appears when a single column Multi Value Picker or Data Grid is used. Resolution This is a known issue. There is a workaround.  Workaround: As a workaround, try adding one empty column in the Multivalue picker without filling the options. So we can add one more column without filling the value which will be hidden(there is a button in the designer page that will hide the column). This way the end user will receive the same view.
