VMware vCenter is the central platform for managing multiple VMware vSphere environments, allowing administrators to supercharge their virtualization setup. One of the core features that vCenter provides is clustering, a feature that groups multiple ESXi hosts together to provide high availability and distribute load evenly. In this blog post, we’ll guide you through the steps to create a… Read More »
VMware vCenter Server is the centralized management utility for VMware, which allows users to centralize and manage multiple virtual machines (VMs) in a single consolidated interface. With the introduction of vCenter Server 8 Appliance (VCSA), users can benefit from enhanced performance, improved scalability, and a better user experience. In this guide, we will walk you through the steps… Read More »
A Docker container is a lightweight, standalone, and executable package that includes everything needed to run a piece of software, including the code, a runtime, system tools, libraries, and settings. Containers are isolated from each other and from the host system, but they share the host system’s kernel.
After performing a V2V, P2V or a clone operation in which the VHD/VHDX file is copied to a new VM, a new NIC is installed in the virtual machine. This is evidenced by the need to once again set the IP configuration of the NIC.
From time to time, it may be necessary to restart the management agents on an ESXi server. The process is very straightforward and is non-intrusive to the functioning of the virtual machines hosted there.
If your VMware implementation contains more than a few hosts, managing port groups (or any multi-host settings) can be a real pain. In order to take advantage of cool things like vMotion, your port groups need to match across all hosts in the cluster. If one of them is misspelled, or has a bad VLAN tag, it’s a… Read More »
Perform a rescan operation each time you reconfigure your storage setup. You can use the vicfg-rescan vSphere CLI or the vSphere Client to perform a rescan. See the ESX Configuration Guide and the ESXi Configuration Guide. The Fibre Channel SAN Configuration Guide discusses rescan on Fibre Channel storage. The iSCSI SAN Configuration Guide discusses rescan on iSCSI storage.… Read More »
Get information, set speed and duplex for ESX/ESXi physical NICs. The vicfg-nics command manages uplink adapters, that is, the Ethernet switches used by an ESX/ESXi host. You can use vicfg-nics to list the VMkernel name for the uplink adapter, its PCI ID, driver, link state, speed, duplex setting, MAC address and a short PCI description of the card.… Read More »
Thinking of moving away from VMWare? Can Hyper-V provide the functionality that you require to keep your systems available? I can tell you that paying the VMware tax has become a bit tedious.
If you are vSphere administrator, you’ve probably run into this yourself or know someone who has. Some have this problem, don’t. There seems to be no rhyme or reason why it happens to some and not others. Here is how to fix it though.
