XenServer 7.2 major packet loss

After upgrade from 7 to 7.2 of XenServer,  some of my customer has got problem with major packet loss and network disruptions intermittently.

This is affecting HPE’s Broadcom NIC chipsets. (Also  Dell and Qlogic network cards, but I have not testet on other than HPE hardware)

XenServer 7.2 includes an old version of the bnx2x kernel module – 1.714.1.
HP recommends a minimum bnx2x module version of or newer.

“Unknown Client Error 1110” error when launching Desktop using Firefox

With Storefront and Firefox user gets “Unknown Client Error 1110”. It works 1 of 5 time. This is NOT a problem with other browser.

Work around:
Delete the ICA files from system TEMP folders before launching the app.

  • C:\Users\<username>\AppData\Local\Temp
  • C:\Users\<username>\AppData\Local\Microsoft\Windows\INetCache\ (Windows8 / 10)
  • C:\Users\<username>\AppData\Local\Microsoft\Windows\Temporary Internet Files\Low\Content.IE5 (Windows7)

Project Honolulu – The future of IT

Have you missed a single point for management for your Server infrastructure? Honolulu is the answer. Web based admin for all your server!

Project Honolulu was presented at ignite 2017.

From Microsoft:

What is Honolulu?

Honolulu is a locally deployed, browser-based, management tool set that enables on-premises administration of Windows Servers with no Azure or cloud dependency. Honolulu gives IT Admins full control over all aspects of their Server infrastructure, and is particularly useful for management on private networks that are not connected to the Internet.

Honolulu is the modern evolution of ‘in-box’? management tools, like Server Manager and MMC. It is complementary to System Center and Operations Management Suite, and is not intended to replace these products and services.
