Re: vswitch problem
You need to provide output from QUERY VSWITCH and QUERY NIC DETAILS while the VM stack is up. Did the output I provided give you (or anyone else) any ideas on this? My vswitch is now frozen, waiting for advice... Thanks, Shimon

Re: vswitch problem
I just noticed something about the data I posted last week.

Re: VSWITCH problem regarding connection between different VSWITCH guests
I ran into this problem on zVM 5.2. There is a fix for this problem and it is on the 0601 put tape for 5.2. It could be the same issue on 4.4. Contact the support center. Aria.

But unfortunately the Linux guests which are using the same VSWITCH are not able to talk to each other via network. Network connections to other hosts on the nework where the OSA card (from VSWITCH) is connected are just fine.
