A virtual machine is a software computer that, like a physical computer, runs an operating system and applications. The virtual machine is comprised of a set of specification and configuration files and is backed by the physical resources of a host. Every virtual machine has virtual devices that provide the same functionality as physical hardware and have additional benefits in terms of.
The most common issue with a vSphere virtual machine is that the VMware Tools are either not installed or are out of date. The VMware Tools are a suite of utilities intended to enhance the performance of the virtual machine’s guest operating system and improve the ability to manage the virtual machine. With each new version of vSphere, VMware also updates VMware Tools and, with some version.
Verify that VMware Tools is installed on every virtual machine on the host. 2: Compare the CPU usage value of a virtual machine with the CPU usage of other virtual machines on the host or in the resource pool. The stacked bar chart on the host’s Virtual Machine view shows the CPU usage for all virtual machines on the host. 3.VMQ (Virtual Machine Queue) is a type of hardware packet filtering that delivers packet data from an outside virtual machine network directly to a virtualized host operating system.To access boot disk devices attached to a VMware Paravirtual SCSI controller, verify that the virtual machine has a Windows 2003 or Windows 2008 guest operating system In some operating systems, before you change the controller type, create a virtual machine with an LSI Logic controller, install VMware Tools, and then change to paravirtual mode.
When setting up a new virtual machine you can choose between dynamically allocated and fixed size disk types. A dynamically allocated disk can save disk space of your drive but it takes more time for Virtualbox to write to. A fixed-size disk uses all allocated space immediately, takes longer to create but works faster. We recommend to use fixed-size disk to speed up Windows 10 on Virtualbox.

To change this setting using the vSphere client, select the virtual machine then click Edit settings. On the options tab, click Configuration Parameters (found under the General section). If the ethernetX.emuRxMode variable isn’t there then you can add a new row: The change will not take effect until the virtual machine has been restarted.
You can set or change virtual machine options to run VMware Tools scripts, control user access to the remote console, configure startup behavior, and more. The virtual machine options define a range of virtual machine properties, such as the virtual machine name and the virtual machine behavior with the guest operating system and VMware Tools.
If you are on the most recent version of Hyper-V, 2012R2, you will see a prompt as shown in Figure 4, to select a virtual machine generation. The Generation defines the Hyper-V compatibility level.
Virtual Machine Queues strike again. I always forget to disable VMQ on my Windows servers with Broadcom NICs. I spent thirty minutes troubleshooting a VM that randomly lost connection on a cluster node before remembering to disable VMQ (had to disable it on the NIC Team adapter itself). I remember a couple of months ago I live-migrated a VM from an old standalone hyper-v host to a new one and.
All of the graphical tools for creating a virtual switch and setting up a single virtual adapter for the management operating system were covered in this previous article in the series. You cannot use the graphical tools to create any further virtual adapters for use by the management operating system. You also must use PowerShell to create your virtual switch if you want to control its QoS.
The virtual machine hardware version you choose will impact the type of virtual storage IO controllers available to your virtual machine. The type of virtual storage IO controller you choose will have an impact on your storage performance, as we will cover in the next section. Table 6.3 shows the different storage IO controller options based on the different virtual hardware versions.
If using virtual disks make sure that the best controller type is used for performance. Some virtualisation solutions offer several virtual controller types for better guest compatibility and you might find some less efficient than others due to protocol limitations in the design they are emulating and limitations in the guest OS's drivers.

Following are recommended VMware ESXi and SBC SWe virtual machine (VM) configurations. General ESXi Recommendations. Following are recommended VMware ESXi configurations: Plan enough resources (RAM, CPU, NIC ports, hard disk, etc.) for all the virtual machines (VMs) to run on server platform, including resources needed by ESXi itself.
