VMware: After applying patches from ESXi Update2-Rollup ISO, Citrix NetScaler virtual machine with e1000 vNIC loses network connectivity (2092809)

November 4th, 2014 1 comment
  • Some Citrix NetScaler virtual machine appliance running the guest Operating System with e1000 vNIC driver loses network connectivity
  • And also cannot access the console after applying the patches released with ESXi 5.5 Update 2 build 2143827

This issue occurs when the NetScaler virtual machine driver resets TDT to 0 after 511 while the TX ring size is shown as 1024.

 

Workaround:

This is a known issue affecting Citrix NetScaler virtual machine appliance running on ESXi 5.5 Update 2 build 2143827.

Currently, there is no resolution.

To work around this issue, add the line hw.em.txd=512 in loader.conf file.

To add the line hw.em.txd=512 in loader.conf file:

  1. Log in to the Citrix NetScaler virtual machine appliance as root
  2. Locate the loader.conf file on the Netscaler virtual machine appliance by running this command:
    find / -name loader.conf
    Note: There are two loader.conf files. The two files are ./flash/boot/defaults/loader.conf and ./flash/boot/loader.conf. Modify the first one and ensure to take a backup of the file prior to making the changes.
  3. Add this line in the loader.conf file
    hw.em.txd=512
  4. Save the changes
  5. Restart the NetScaler virtual machine appliance
