Enabling SSH for non-root users in ESXi fails with the error: Access denied

To enable SSH access for non-root users:

 

Create a user account on the ESXi host using one of these options:

• Create a user account using the vSphere Client.
  
  Using the vSphere Client:

1. Connect to the host directly using the vSphere Client with root credentials.
2. Click the Local Users & Groups tab.
3. Right-click anywhere in the tab, then click Add.
4. Enter a log in name and password.
5. Click OK.

Click the Permissions tab.

Right-click Add Permission then click Add.

Select the newly created local user from the list and click Add.

Assign the Administrator role to the user then click OK. 

Move / Delete esxi 5.5 vmkdump folder / files in datastore

When you upgrade to ESXi 5.5,the vmkdump folder may appear in some datastore.
Though this folder was Locked after ESXi host booting,you can still unlock it using ssh command.
Check .dumpfile:

ssh cmd

esxcli system coredump file get

Deactivate(unlock) .dumpfile:

ssh cmd

esxcli system coredump file remove --force

Now you can move vmkdump folder.
If the vmkdump folder (with .dumpfile) was moved to other datastore,you could reactivate it.
Reactivate .dumpfile:

ssh cmd

esxcli system coredump file set --smart --enable true

如何打开 Vmware Esxi 已经存在的虚拟机

第一步,利用VMware vSphere Client登陆Esxi SERVER

第二步,点击"configuration"----"storage(scsi,san,nfs)----右击虚拟机所在的存储,右键点击"browser datastore",

第三步,点击了"browse datastore"之后就进入了存储虚拟机的数据中心,然后找到需要添加的虚拟机,找到需要添加的虚拟机的*.vmx文件,然后点"add to inventory"即可.

Convert VM from VM Workstation to ESX / ESXi

Importing and exporting virtual machine from a VMWare ESX Server host requires converting that virtual machine’s .vmdk file(s) from one format to another.
Although the underlying technologies work the same, the formatting of the VMDKs differ.
You have 2 options:
1) If you have a running copy of workstation, simply use VMware Converter as you would for any normal conversion, treating the VM as you normally would a physical host in a P2V
2) If you have no working Workstation, you can clone / convert the vmdk at the command line – as I have a fully ESXi lab to play in, I don’t have Workstation running on any machines in my office – as such, when IBM recently supplied a VM for a demo . . that had been created on VM workstation, I had to import it. I used the following process.
Firstly, get hold of an SSH tool ( I use putty)
Next, open a connection to any host that has the storage containing the vmdk presented
In ESX / ESXi, this will be in /vmfs/volumes/
Note: the destination path /dest/folder/vmserver1.vmdk should not contain any existing files with the name ‘vmserver1.vmdk’. If it does the file will be overwritten.
Importing Virtual Disks from GSX Server and Workstation to ESX Server
Before an ESX Server can run a virtual machine created on a different version of VMWare, the virtual disks must first be converted to a format that can be read by the VMFS file system. This is done by running the following vmkfstools command:
vmkfstools -i /.vmdk :.dsk
is the name of the folder from which you are importing from
is the name of the virtual machine file(s) to be imported
is the name of the VMFS partition you are importing to
An example of a complete command would be:
vmkfstools -i /vmfs/volumes/CLRLAB001T1/vmserver1.vmdk /vmfs/volumes/CLRLAB001T1/vmserver1_new.vmdk
Additional information regarding the vmkfstools command can be found in the ESX Server documentation.

通过*.vmdk 恢复Esxi虚拟机文件

以下是vmware 恢复详细步骤：
1.用ssh 登入ESX 主机或者用显示器登入主机
2.进入.vmdk 文件的目录  一般目录如下：
cd /vmfs/volumes/myvmfsvolume/mydir
3.查看当前vmdk 文件的大小。命令如下：
# ls -l vmdisk0-flat.vmdk
-rw------- 1 root root 4294967296 Oct 11 12:30 vmdisk0-flat.vmdk
4.使用vmkfstool 创建新的虚拟磁盘
# vmkfstools -c 4294967296 -a lsilogic -d thin temp.vmdk
5.默认会生成两个文件，删除temp-flat.vmdk 文件
# rm temp-flat.vmdk
6.把新产生的vmdk文件，重命名为原来的文件。如下，假设我的虚拟文件为vmdisk0.vmdk
# mv temp.vmdk vmdisk0.vmdk
7.编辑新产生的文件，如：vmdisk0.vmdk 注意，我标注的颜色的地方需要修改。
# Disk DescriptorFile
version=1
CID=fb183c20
parentCID=ffffffff
createType="vmfs"
# Extent description
RW 8388608 VMFS "vmdisk0-flat.vmdk"# The Disk Data Base
#DDB
ddb.virtualHWVersion = "4"
ddb.geometry.cylinders = "522"
ddb.geometry.heads = "255"
ddb.geometry.sectors = "63"
ddb.adapterType = "lsilogic"
ddb.thinProvisioned = "1"

费我好几分钟去找。不知道是不是Vmware故意迷惑你让你以为Esxi要花钱

VMware Esxi 5 adding a virtual machine to the inventory 导入旧的VM

You can register a virtual machine in vCenter Server / VirtualCenter or from a command line.

 

To register a virtual machine in vCenter Server:

1. Open the vSphere / VMware Infrastructure (VI) Client and log in with appropriate credentials.
2. If connecting to vCenter Server, click on the desired host.
3. Click the Configuration tab.
4. Click Storage.
5. Right-click on the appropriate datastore and click Browse Datastore.
6. Navigate to the folder named after the virtual machine, and locate the .vmx file. 
7. Right-click the .vmx file and click Add to inventory. The Add to Inventory wizard opens. 
8. Continue to follow the wizard to add the virtual machine.

To register a virtual machine from a command line:

1. Log in as root to the ESX host with an SSH client.
2. Run the command:
   # vmware-cmd -s register \.vmx

To register a virtual machine from a command line on an ESXi host:

1. Log in as root to the ESXi host with an SSH client. For information on using Tech Support mode, see Using Tech Support Mode in ESXi 4.1 (1017910).
2. Run the command:
   
   # vim-cmd solo/registervm /vmfs/volumes/datastore_name/VM_directory/VM_name.vmx
