There exists z/VM APAR VM65785 / PTF UM34782 for z/VM 6.3 to improve port
speed and lan type reported to guests. Can you please check, if this PTF is
applied?

It seems to be the case. I ping flooded one of the servers and got 300Mbps
bandwidth.

I vaguely remember there was a bug somewhere with the speed being
incorrectly reported to the guests. It's all virtual, so it shouldn't
make a real difference.

Re: Qeth at 10Mb?

[Mauro Souza]

They are not, they are a couple of 10Gb fibers. The strange part is that
every other SLES11 connected on the same vswitch shows a 10Gb connection,
only the SLES12 guests are getting a 10Mb connection...

Re: Qeth at 10Mb?

[Harold Grovesteen]

While you are checking things, check the configuration of the
connections on the network router or switch.  If they are configured for
10Mb then that is the speed they will have to run.

Qeth at 10Mb?

[Mauro Souza]

Hi guys,

We got an interesting situation today. One of our WAS guys called us to say
the SLES12 guest we just IPL'd has a 10Mb qeth interface.  I thought he was
mistaken or joking, but there was a 10Mb device showing on ethtool, with
"twisted pair" link type and all...

All our SLES11 on this lpar are fine (and on the same vswitch). All SLES12
on another lpars are fine (both zVM 6.3 and 6.4). All SLES12 guests on this
specific lpar (running zvm 6.3) are running on 10Mb. The vswitch conf on
any lpar are exactly the same except the OSA channel.

Any ideas?
