RE: [Xen-users] XEN Infiniband
I think Infiniband passthrough support is already pretty good under Xen which
should allow for reasonably efficient cluster interconnect but I have not tried
it; I'm sure some one else more knowledgeable can answer more accurately on
Currently machine migration is by TCP/IP only. I use IPOIB (IP Over Infiniband)
with Xen migration and it works well (Performance is about the same as 10Gb
Ethernet). If RDMA migration support is added migration performance would be
approx 2 to 4 times faster, it might get considered for Xen 4.0 (I have already
asked), if you would like RDMA migration support then let Stephen Spector know:
You might get very knowledgeable responses on infiniband specific questions
