VMware Tools Features

VMware Tools Features: Providing drivers
1. Optimizing SCSI Devices
2. Enhanced display and mouse performance
3, Virtual technology heartbeat function
4. Snapshot Data backup
5. Enhanced memory management
6, Vmxnet, Vmxnet2, Vmxnet3 are drivers provided by VMware and are available only with VMware Tools

Sometimes the mouse is still not fluent, the update installs the video card drive, the path C:\Program files\common Files\vmware\drivers\video

NTP uses routers to configure NTP servers to do clock synchronization

Shutdown power off from normal shutdown, install VMware Tools before using shutdown shutdown

Linux install VMware Tools, view the properties file directory location
CD into the file directory
To decompress
TAR-ZXF file-c/tmp
then enter
/tmp/vmware tools-distrib/
To install
sudo./vmware.install.pl

Snapshots (patching, upgrading)
Memory snapshot, the memory also do snapshot down, boot state can only do memory snapshot, need to occupy a lot of disk space
Silent snapshots, must have tools,
Normal snapshot speed fast

VMware Memory Recycling
In accordance with the memory recycling successively charge, in turn:
1.TPS Transparent page sharing: Saving shared memory for the same content
2.Ballooning Balloon Recovery: VMware Tools provides memory resource optimization
3.Compressiong Memory Compression: Writes the memory to the hard disk, writes the content is also relatively small)
4.Swapping Memory Exchange: System performance will degrade (not recommended)

tps--Transparent page sharing allows only pages of the same content to be stored on the host's physical memory once, and may be triggered when host memory is greater than or equal to 6%
ballooning--Idle memory is reclaimed when operating system memory is overloaded and memory is requested through balloon driver in VMware Tools
compressing--memory pages are compressed and placed in the virtual machine's compressed cache, triggered when host memory is below 2%
swapping--when TPs and ballooning recovery are not available, it is only possible to swap the virtual machine physical memory to the hard disk for swapping, which can have a significant impact on performance. It is also triggered in host memory below 2%.

Limit: Refers to the maximum amount of physical memory that can be assigned to a virtual machine
Reserved: The minimum amount of physical memory that is guaranteed to be allocated to the virtual machine, and the memory-recycling mechanism can only guarantee the memory allocation reserve value
Sharing: The virtual function uses a physical existence between the limit and the reservation value change, when memory contention occurs, the greater the share value, the more opportunities to compete for more physical memory

VCenter server administrators can define user or user group access privileges to manifests
Privilege: the ability to perform specific actions or read specific properties
Role: Represents a set of privileges
Object: The target of the operation this means ESXi host, virtual machine, etc.
Users/Groups: Users or groups of users who can perform actions

Role is a collection of privileges: Various tasks can be performed
A resource pool is a logical abstraction that is used to manage CPU and memory resources hierarchically
FT ensures that there are no more than four fault-tolerant virtual machines (primary or secondary) on any host
Disable BIOS-based power management: Prevent insufficient CPU resources for secondary virtual machines

FT provides continuous availability
Create an FT network, virtual machine
Configure disk for post-provisioning immediate zeroing
Deploy FT
Blue screen crashes resolved not

FT: A virtual machine can be written at the same time on two ESXi hosts, ensuring seamless switching of the business

Patching an ESXi host
1. Scan and confirm that there are no newly upgraded systems
2. User-defined rules to determine outdated systems
3. Automatic patch installation for ESXi host
4. Fully integrated with other vsphere features
