Info

Starting with ESXi 6.5, it is not possible to select E1000 adapter when a new virtual machine is created using Windows Server 2012, 2016 and Windows 10 templates.

The following workarounds are available:

  • Import the virtual machine from an older version of ESXi
  • Do not select "Red Hat Enterprise Linux 7 (64-bit)" nor "CentOS 7 (64-bit)" during virtual machine creation but select "Linux" as "Guest OS family" and "Other 3.x Linux (64-bit)" as Guest OS version".

Manual Configuration

Choosing a network interface

...

# ethtool -k eth1
Offload parameters for eth1:
rx-checksumming: on
tx-checksumming: on
scatter-gather: on
tcp-segmentation-offload: off
udp-fragmentation-offload: off
generic-segmentation-offload: on
generic-receive-offload: off
large-receive-offload: off

For the example above let's create a temporary file containing the commands to be executed at system startup as the offload parameters must be switched off following each reboot:

ethtool -K eth1 rx off
ethtool -K eth1 tx off
ethtool -K eth1 sg off
ethtool -K eth1 gso off
ethtool -K eth1 gro off 

...

Let's suppose the name of the file is "offload_off_eth1.txt". To execute it on system startup, execute the following command (example):

...

  1. Ensure your license allows you to upgrade to that version. If not, please generate a C2V file and send it to STROMASYS for update. See CHARON-AXP for Linux utilities - 'hasp_srm_view' utility
  2. Prepare the new kit RPM files as it is described in "Before installation" and "Distribution preparation" sections.
  3. Stop all running CHARON-AXP instances.
  4. Make sure that no template files (i.e. "es40.cfg.template") have been used for your specific configuration otherwise copy those files to a dedicated folder.
  5. Login as "root" user.
  6. Remove the old CHARON-AXP version as described in the "CHARON-AXP for Linux deinstallation" chapter.
  7. Proceed with the instructions on the new kit installation as described in the "Installation695402677" section.

  8. Install the license for the new CHARON-AXP as described in the "License installation" section.

  9. Start all the CHARON-AXP services stopped at step #3.
