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)
Problem:
XenServer 7.2 includes an old version of the bnx2x kernel module – 1.714.1.
HP recommends a minimum bnx2x module version of 7.12.37.1-1 or newer.
