How Do I Uninstall a Virtual Machine?

VMWare virtual machine software is a "virtual PC" software that allows you to run two or more Windows, DOS, and Linux systems on a single machine at the same time. Compared to "multi-boot" systems, VMWare uses a completely different concept. A multi-start system can only run one system at a time, and it is necessary to restart the machine when the system is switched. ^[1]

VMWare virtual machine software to test software, test installed operating systems (such as linux), test virus trojans, etc.

VMWare runs truly "simultaneously", with multiple operating systems on the platform of the main system, switching like standard Windows applications. In addition, you can perform virtual partitioning and configuration for each operating system without affecting the data of the real hard disk. You can use network cards to connect several virtual machines to a LAN. ^[1]

1. No need to partition or reboot to use more than two operating systems on the same PC.
2. Completely isolate and protect the operating environment of different OS and all application software and data installed on the OS.
3. Different OS can also interact with each other, including network, peripheral, file sharing and copy and paste functions.
4. With Undo function.
5. Able to set and modify the operating environment of the operating system, such as: memory, disk space, peripheral devices, etc. ^[1]

1. Install the original version.
2. Unzip the finished file. Copy the finished file directly into the virtual machine folder and replace the original file.
3. When replacing, some files may indicate that it cannot be replaced. Please end the corresponding file process in Task Manager first, and then replace it. ^[1]

The management of VMware virtual machines has actually begun before it was created. This is a long-term plan that requires continuous monitoring by administrators.
Although virtualization technology can greatly improve the use of computing resources, in fact, these resources are not free-no matter what value the VMware virtual machine provides for the enterprise, it will occupy memory, CPU computing time, storage and network I / O and other resources. After enterprises accept VMware virtual machine technology and develop their own VMware virtual machine strategy, administrators need to understand the concept of virtual machine lifecycle and how to deploy infrastructure, and manage the entire virtual machine lifecycle according to internal policies. This can ensure that enterprises can reasonably utilize hardware computing resources under more efficient and cost-saving conditions.

What is included in VMware virtual machine lifecycle management

When users talk about the life cycle management of VMware virtual machines, they often think that it is just a process of finding and deleting old VMware virtual machines. Although the end of life cycle (EOL) is also an integral part of the life cycle management of VMware virtual machines, the entire management process includes all aspects of the creation, optimization, management, and final retirement of VMware virtual machines, which is the four stages of the life cycle of VMware virtual machines. Main components.
The life cycle management of VMware virtual machines usually starts with the demonstration process, and the specific implementation phase can only be entered after the demonstration is completed. Although the process of creating a VMware virtual machine is very fast and simple, it still needs to ensure the rationality of deploying each VMware virtual machine, conduct a comprehensive analysis of its resource requirements and business value, and understand how long the business unit needs to use this VMware virtual machine. Used by some companies

For VMware virtual machine power management, Microsoft and VMware take a very similar approach. Both approaches are based on some of the most basic server virtualization concepts.
Although a single hypervisor is fully capable of running multiple VMware virtual machines, a single hypervisor has never been used in a production environment. Administrators typically do not take the risk of a hypervisor becoming a single point of failure. Therefore, most hypervisors, such as VMware virtual machine ESXi and Microsoft

The server VMware virtual machine is more than just hardware integration. A well-built VMware virtual machine environment can be used to automate daily tasks. Although it takes some effort to complete the above configuration, in the long run, VMware virtual machine automation can often greatly reduce the workload of administrators. VMware virtual machine automation also ensures that day-to-day work can be performed in a manner consistent with the needs of the organization.
The most common automation task is VMware virtual machine creation. Tools such as VMware vCenter and Microsoft's System Center VMware Virtual Machine Manager can create VMware virtual machines based on templates. Administrators can build VMware virtual machine templates that match the organization's requirements and then use these templates when creating virtual machines in the future. This ensures the reasonableness of the VMware virtual machine configuration.
Considering host configuration automation, the process enables automatic installation on bare metal

With the advancement of hardware support for server virtualization, hosting VMware virtual machines (VMs) has become easier. But with the limitations of memory, CPU, and scheduling, how many virtual machines are hosted?

We asked three IT experts about the number of VMware virtual machines on each host they saw, and how productive these VMware virtual machines were. Although a server host is stuffed with more than 500 VMware virtual machines, sometimes less is more. Risk, utilization, and memory have become decisive factors.

Virtualization isn't just about consolidating as many servers as possible, it actually needs to do something practical. You will share a kernel with a virtual machine with 1MB of memory and two other VMware virtual machines, but this is meaningless as the performance of the computer is reduced accordingly. Among other issues, more than three virtual machines sharing a core can cause scheduling difficulties. However, this does not mean that merging virtual machines is trivial. A high-end server using a 15-core Intel Xeon E7 processor is comparable to 60 available cores. Ideally, it can actually host 180 VMware virtual machines. There is enough memory and I / O to support this load, which is derived from reality.

VMware utilization

The system administrator said: "We have an extended virtual machine infrastructure with 256GB of memory and fast CPU on 8 hosts. In NetApp we also have a Network File System (NFS) that supports 10Gbps connectivity and 256GB flash memory. Use VMware Virtual Machine ESXi 5.X, we can run up to 24 VMware virtual machines on each node, usually 15 VMware virtual machines per host. So we see less than 3% -5% CPU utilization, 7 RAM utilization % -11%. "

We were able to place 48 or more VMware virtual machines on one server host, and we rarely saw a decline in server capacity. But low utilization rates can easily lead us to ideas for new projects. When server host capacity declines occur, we assign VMware virtual machines to facilitate automatic failover. No need to remove any VMware virtual machines to modify vulnerabilities and upgrades for server hosts.

The VMware virtual machine is largely a web server. Although we have interactive login machines (Windows and Linux) and MySQL databases, it is not too computationally intensive for virtual machines for digital computing applications.

During the hardware upgrade, when we moved to the new device, we put 125 VMware virtual machines on two nodes. It even splits the entire memory of the two nodes. VMware virtual machine infrastructure is still not a burden.

VMware Virtual Machine

In a Virtual Desktop Technology Facility (VDI) environment, I once saw 150-200 VMware virtual machines on a single server. Most large VMware virtual machines rely on four-socket rack servers. In the VDI environment, there are different consolidation rates depending on the workload.

I also saw about 80 VMware virtual machines on one server because that company wanted deep consolidation; this involved management issues. Many VMware virtual machines on a server host are also working well after the deep merge, but the real problem is the risk: Does the enterprise want to take the risk of putting 80 VMware virtual machines on one host? What happens if the server goes down? Can companies afford the risk of losing 80 VMware virtual machines?

Leave some space for the future of VMware virtual machines

IT Operations Manager said: "The most I see is 31 VMware virtual machines on one server host, using Microsoft Hyper-V on a Cisco UCS blade server to provide 256GB RAM, two 8-core Intel E5 -2665 CPU. Storage is a fiber-attached EMC SAN with SSD cache. "

Since we are getting closer to the ceiling in terms of RAM, CPU, or I / O utilization, 31 VMware virtual machines on the server host is no longer the limit, and we have more flexibility in what we want to do. Some VMware virtual machines are used efficiently, while some VMware virtual machines are underutilized. We can transfer workloads between 6 UCS hosts when fixing vulnerabilities and restarting. ^[5]
