To setup proxy manually in VCSA 5.5 login as root and look into the following file:
HTTP_PROXY=”http://<IP address or FQDN>:<port_number>”
HTTPS_PROXY=”http://<IP address or FQDN>:<port_number>”
FTP_PROXY=”http://<IP address or FQDN>:<port_number>”
If you need to authenticate via proxy
Create a file in your home directory,
/root/.curlrc with permissions 644
and contain the following:
# Proxy credentials
proxy-user = “<username>:<password>”
source the file to apply the changes
Even when launching VMware PowerShell CLI with administrator privileges you are still unable to start it.
Moreover, you are unable to change execution policy for the machine.
Try the following it only changes policy for current user.
Set-ExecutionPolicy Unrestricted -Scope CurrentUser
Running Windows Server 2012 virtual machine on VMware ESXi hypervisor and receive constant disconnects through RDP.
Checked the logs and found out e1qexpress which indicates incompatibility of virtualNIC
Power down the machine, remove existing network interface and add a new one based on VMXNET3.
Bring the machine up and Windows should automatically apply the changes.
Windows 8, Windows 8.1, Windows 10 get suspended or go to standby mode when are inactive for more than 5 mins. The issue is related to mobile devices which OSes were designed for and battery savings which disable some of the services such as RDP and users cannot login to machines.
In order to address the issue in VMware, a machine needs to be powered down and .vmx file needs to be modified. There are two ways of doing it:
- Directly via ssh and using text editor to append the following to <vm_name>.vmx file: suspend.disabled=”TRUE” save changes and exit file.
- Using vSphere Client by right clicking the machine and edit settings. Navigating to Options -> Advanced -> General and clicking ‘Configuration Parameters’ button. \
- Select ‘Add Row’ button.
- Name: suspend.disabled, Value: True
- Save settings and power the mahcine back on.
To updated VMware tools on Windows without reboot:
- Right click on a virtual machine
- Select ‘Guest’ -> Install/Upgrade VMware Tools
- In the pop-up dialog select ‘Automatic Tools Upgrade’ in ‘Advanced Options’ enter the following:
/S /v"/qn REBOOT=R"
- Installation can take up to 10 mins depending on your data storage performance
ESXi has its own firewall implementation which may block some of incoming/outcoming traffic e.x. netcat
In order to disable the firewall:
- Ssh to the machine
- Execute the following command: esxcli network firewall set –enabled 0
While cloning one of my templates received the following error: “
Incompatible device backing specified for device '12'.”
VMWare tools were updated to the newest version and machine was powering on no problem.
To resolve the issue make sure that CD-ROM properties are set correctly.
“Edit the settings” of the virtual machine:
1) Remove the CD-ROM assigned as the device is probably pointing to some non-existing location,
2) If the device is set to Host Device change it to Client Device,
3) You may also want to try to point the device to some local ISO file if you find it easier.
If you are running a HA machine and want to make sure that your hardware will support 64-bits guest operating system you can run the following command before rebooting machine and checking the BIOS option:
# esxcfg-info|grep "HV Support"
The output will determine if the machine is 64-bits compatible:
0 - VT/AMD-V indicates that support is not available for this hardware.
1 - VT/AMD-V indicates that VT or AMD-V might be available but it is not supported for this hardware.
2 - VT/AMD-V indicates that VT or AMD-V is available but is currently not enabled in the BIOS.
3 - VT/AMD-V indicates that VT or AMD-V is enabled in the BIOS and can be used.
