...patch, we could pass multiple file descriptors to a signle netdev by: qemu -netdev tap,id=hn0,fd=10,fd=11,... Patch 2 introduce generic helpers in tap to attach or detach a file descriptor from a tap device, emulated nics could use this helper to enable/disable queues. Patch 3 modifies the NICState to allow multiple VLANClientState to be stored in it, with this patch, qemu has basic support of multiple capable tap backend. Patch 4 converts virtio-net/vhost to be multiple capable. The vhost device were created per tx/rx queue pairs as usual. Changes from V1: - rebase to the latest - fix me...

Dtrace and Performance Teams, I have the following IO Performance Specific Questions (and I''m already savy with the lockstat and pre-dtrace utilities for performance analysis.. but in need of details regarding specifying IO bottlenecks @ the controller or IO bus..) : **Q.A*> Determining IO Saturation bottlenecks ( */.. beyond service times and kernel contention.. )/ I''m

The minimum is set at 1200Kbits/second. However, in testing, if I set that for a VNIC, the domU gets no traffic at all (maybe the occassional packet). Is the minimum too low? If I set a maximum of 2000Kbits/second, I get this from nicstat (expecting around 250Kbytes/s total: Time Int rKB/s wKB/s rPk/s wPk/s rAvs wAvs %Util Sat 04:35:38 xvm15_0 146.6 5.32 102.0 73.65 1471.3 74.00 62.21 0.00 04:35:43 xvm15_0 161.6 5.92 112.0 82.24 1477.4 73.68 68.60 0.00 What is the expected accura...

I am looking for Dtrace scripts that can be used to collect data during performance tests. I am especially interested in IO but CPU, memory, threads, etc are needed as well. Thanks, Dave

...Okay, let''s imagine I switched to the secodary host because had a problem with the primary. Now it''s repaired, now I want my redundancy back. * "sndradm -E -f ...." on both hosts - works. * "sndradm -u -r" on the primary for refreshing the primary - works. `nicstat` shows me a bit of traffic. Good, let''s switch back to the primary. Actual status: zpool is imported on the secondary and NOT imported on the primary. * "zpool export tank" on the secondary - *kernel panic* Sadly, the machine dies fast, I don''t see the kernel panic w...

I am [trying to] perform a test prior to moving my data to solaris and zfs. Things are going very poorly. Please suggest what I might do to understand what is going on, report a meaningful bug report, fix it, whatever! Both to learn what the compression could be, and to induce a heavy load to expose issues, I am running with compress=gzip-9. I have two machines, both identical 800MHz P3 with
