Ethernet address: ‘*’. It conflicts with VMware reserved MACs.

After manually modified the MAC address of a VM, got below error when try to power on the VM:

Ethernet address: ‘*’. It conflicts with VMware reserved MACs.

The solution is to modify the VMX file manually, and add below line:

ethernetN.checkMACAddress = “false”
ethernetN.addressType = “static”

Vmware NSX for vSphere 6.2.2 bugs — lost network connection

We are using VMware NSX in our production environment for a long time.
And recently we got some problem with NSX, the symptoms is

Some VMs will lose network connection after migrated to another VM;
New firewall rules are not able to apply on some of the VMs.

After engaged VMware, VMware confirmed that it’s a bug in NSX.

VMware assigned about 1.6G heap memory for NSX firewall on each of the ESX hosts. If you applied too much rules or you have too many VMs and you’ll reach the memory limit. Then you’ll get this issue…

Current fix is to upgrade to 6.2.3…

ESXi: Unable to connect to MKS: The operation is not allowed in the current status.

Unable to shut down, migrate or doing pretty much any operation to a VM with error message including «operation is not allowed in the current state»?

Solution might be enabling ssh on the esxi host, login and try:

Run the esxtop utility using this command:esxtop
Press c to switch to the CPU resource utilization screen.
Press Shift+v to limit the view to virtual machines. This may make it easier to find the Leader World ID in step 6.
Press f to display the list of fields.
Press C (uppercase) to add the column for the Leader World ID.
Identify the target virtual machine by its Name and Leader World ID (LWID).
Press k.
t the World to kill prompt, type in the Leader World ID from step 6 and press Enter.
Wait 30 seconds and validate that the process is not longer listed.

In vSphere client, check if the machine detects it is shut down, if it doesn’t happen right click and choose shut down, hopefully this will work now.

When executing the vmware workstation bundle, the following gtk2 errors are displayed:

Fix:

Install PFX certificate on ESXi host

1. Install OpenSSL version 0.9.8 for windows, you can get it from below link:
http://slproweb.com/download/Win32OpenSSL_Light-0_9_8zb.exe
2. Install it on a windows machine. By default, OpenSSL will be installed to C:OpenSSL
3. Copy the pfx certificates into folder C:OpenSSLbin
4. Run command line as administrator, and go to folder C:OpenSSLBin
5. Use below command to covert the certificate:
a. Generate crypt key file for the certificate via below command:

During this step, it will ask for pfx certificate password and the pass phrase for the key. Use any word you like as the pass phrase, do not use blank pass phrase.
Then use below command to decrypt the key. In this step it will ask you the pass phase you used before.

b. Generate crt file for the certificate via below command:

6. Done. Now you can install the certificate for ESXi host
