...U on the same motherboard with the same kernel, the CPU utilization tools show that smbd processes are evenly spread out among all 4 cores. There is a little shifting of smbd processes from one core to another, but for most of the time the various smbd process each stay on particular cores. CPU utilizaton shows that each core is at around 8-12 percent. Under both scenarios -- one or two physical CPUs -- I am using the same VERY BIG RAID subsystem and I am running the same test from the same group of workstations. I have replicated my results on multiple identical servers so I can't explain...

...maximum number of time (in us) could be spent on busy polling was specified ioctl. Test A were done through: - 50 us as busy loop timeout - Netperf 2.6 - Two machines with back to back connected mlx4 - Guest with 8 vcpus and 1 queue Results: - TCP_RR was imporved obviously (at most 27%). And cpu utilizaton was also improved in this case. - No obvious differences in Guest RX throughput. - Guest TX throughput was also improved.

Hi there, We are using latest version of XCP on 6 hosts. While issuing VM.start or VM.start_on xmlrpc functional call , it says : {''Status'': ''Failure'', ''ErrorDescription'': [''SESSION_INVALID'', ''OpaqueRef:cfb6df14-387d-40a1-cc27-d5962cba7712'']} However if I put VM.start in a loop maybe after
