First of all create a new user.

You are are using vmware workstation and you have mount on your computer a PCIe LPT card. You are unable to connect this LPT port to your guest vm.
Uninstall VM-Ware and to Reinstallit
You cannot see nfs datastore on esxi. Try to do the munting, but the procedure fails saying that the datastore already exists.
To resolve this issue, remove and re-add the datastore via the command line
esxcli storage nfs list
Run this command to mount the NFS datastore:
esxcli storage nfs add -H NFS_IP|NFS_HOSTNAME -s Share_mount_point_on_the_NFS -v DatastoreName
In your vmware environment you have created a nfs datastore but when you are trying to copy files to it, you lost the connection.
You can check the file vmkernel.log that you can find in your esx host in :
You should find these lines of error :
Lost connection to the server xxx.xxx.xxx.xxx mount point /yourdatastorefolder mounted as ........... ("yourdatastorename") Restored connection to the server xxx.xxx.xxx.xxx mount point /yourdatastorefolder mounted as ........... ("yourdatastorename")
vmnic3: 4026 bytes packet couldn't be sent (mtu=1500)
vmnic3: oversized tsoMss: 8948, mtu=1500
As explained in vmware documentation you have to check communication with your nfs datastore. So using , for example Putty over ssh, you can :
Ping your nfs datastore
Find your vmkernel network card :
In the output you can see the MTU value of your network card and which is the vmkernel network card. Now you can ping your datastore using the network card, trying different MTU values :
vmkping -I vmk1 -s 1420 xxx.xxx.xxx.xxx
You probably need to change the MTU of your esx host’s network card. Maybe you have an MTU set to 9000 and you need to set it to 1500.
Using the vsphere client : Configuration – Networking. Select vmkernel network card and select “Properties” . Select “Vmkernel” and click on “Edit” :
You will be able to see the new MTU value using the previou command :
There are a lot of backup softwares for vmware virtual machine and some are free, but in a scenario it should not be possible to use one of these : for example, if you have vmware esx hosts with old versions (4.0,5.5).
Usually you get connection to esx host using vsphere client, but you have to use ghetto script directly inside esx operating system. So you need to operate using a prompt via ssh. Download, for example, putty : https://www.putty.org/
SSH port in esx host is number 22. To understand if this port is open, you could open a dos prompt and type
telnet your_esx_ip_address 22
you should recive some response.
By default SSH is disabled on an ESXi host.
To connect to esx host via putty you need to create a user on esx. Open vsphere client.
Ghetto script is a file and you will have to upload on esx server this file. To do this task we”l use for example WinSCP that is a free and open-source file transfer utility for Windows. It can be used to transfer files between a local and remote machine over SSH. You can download it from here : https://winscp.net/eng/download.php
Install it. Now you have all tools and we can start to work on Ghetto.
First of all you need to download ghetto from github repository : https://github.com/lamw/ghettoVCB
Unzip it. Open with an editor the file ghettoVCB.sh. You have to update only one line of script :
That you have to substitute with the path of the datastore where you’ll save the backup of vm.
Two options to find the datastore path :
If you ‘ll call ghetto script , you’ll backup all machines in your esx. Instead you can backup only some specific virtual machine. Create a new file, for example mylist.txt with the esactly name of each virtual machine to backup, in each line.
So you have two files (ghettoVCB.sh, mylist.txt) to upload in esx environment. To do this you can use WinSCP. When the Login dialog pops up click on New Site, enter the IP address in the hostname field, the username and password and then click Login.
WinSCP window is divided in two part : on the left side there is your computer, on the right side there is the esx environment. On esx, create a new folder and upload in it the two files.
Double click on the PuTTY shortcut , enter the IP address of the ESX and click Open. Enter the username and your password and you should now be connected.
To continue you need to have administrator (root) priviliges. Write
and enter the password of root user.
Now you need to give execution privileges to .sh file. Navigate in the folder where you have put your files and write the command
chmod +x ghettoVCB.sh
Write the command :
./ghettoVCB.sh -f mylist.txt -l output.txt
This command will backup all the virtual machines written in mylist.txt and will write the log of process in the file output.txt in the same folder.
I had some problems finding the VSP and VTSP courses to get fresh as a vmware partner in the new Partner Connect portal. So i decided to write few sentences about this.
refer the screenshot
Click on the Virtual Machines on the left panel; click with the right mouse button. In the Menu – Autostart, set “Enabled”.
Repeat for all the vm where you want the autostart
Click on “Virtual Machines2 label on the left panel. On the right panel, you’ll see a table with your vms. You can add autostart information by right-clicking column header > Select Columns. Check Autostart order.
Click on the Virtual Machines on the left panel; click with the right mouse button. In the Menu – Autostart, you can see and set to start later or erlier.
