QXCR1000915759

The HPVM host system encounters a panic in the iether driver transmit path. This panic

occurs during the execution of certain scripts when network traffic is going through a Virtual

NIC configured using AVIO_LAN over APA vSwitch. The APA port used for the vSwitch

is configured over iether network interface ports. The following scripts are affected:

• hplm stop

• hpapa stop

• hpapa start

• hplm start

QXCR1000910543

Network packets transmitted are dropped in the HPVM guest OS, which causes a drop in

throughput rate. This occurs when network traffic is going through a Virtual NIC which is

configured using AVIO_LAN over APA vSwitch. The APA port used for the vSwitch is

configured over iether network interface ports.

Two independent problems contribute to the packets being dropped. One problem is resolved

by the iether driver in this release. The other is resolved in the B.11.31.0909 version of the

AVIO HostAvioLan hssn driver (CR :QXCR1000929012).
