ESX 4.1 host stops booting at: * vmnix ... (2030715)


  • ESX 4.1 host fails to boot
  • ESX 4.1 host fails to boot with this message on the screen:

    * vmnix ...


If there is a double-byte character in /etc/vmware/esx.conf (for example, "" ), ESX fails to boot.
For example, this command caused the esx.conf to be updated incorrectly:
esxcfg-firewall --openPort 162,udp,in,"snmptrap
The correct command is:
esxcfg-firewall --openPort 162,udp,in,snmptrap 


To resolve this issue:
  1. Boot the ESX host and select Troubleshooting mode on the Grub menu.
  2. Log in to the host as the root user. For more information, see Connecting to an ESX host using a SSH client (1019852)
  3. Make a backup of the esx.conf file:

    cp /etc/vmware/esx.conf /tmp/esx.conf.bkup

  4. Open the esx.conf file for editing:

    vi /etc/vmware/esx.conf

  5. Find the double-byte characters and remove the characters. For example, change:

    /firewall/openedPorts[0003]/name = ""snmptrap""


    /firewall/openedPorts[0003]/name = "snmptrap”

  6. Save and close the file.
  7. Restart the ESX host.
