> How reproducible: > always > > Steps to Reproduce: > 1. boot up a guest guest uses e1000 nic. > 2. setup and launch netperf server in guest > guest)# ./netserver That it happens with virtio also? (In reply to comment #3) > That it happens with virtio also? No, it only happens with e1000 nic. I have reproduced this issue with e1000 followed by steps in Comment #0 with qemu-kvm-0.12.1.2-2.160.el6.x86_64 After step 3: Udp:0 UDP UNIDIRECTIONAL SEND TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 10.66.11.227 (10.66.11.227) port 0 AF_INET : histogram : interval Interrupted system call netperf: remote error 41 Other:1 TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 10.66.11.227 (10.66.11.227) port 0 AF_INET : histogram : interval Interrupted system call netperf: remote error 4Tcp:1 TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 10.66.11.227 (10.66.11.227) port 0 AF_INET : histogram : interval ----CLI: /usr/libexec/qemu-kvm -M rhel6.1.0 -enable-kvm -m 4096 -smp 2 -name RHEL6.1_64 -uuid `uuidgen` -rtc base=utc,clock=host,driftfix=slew -boot dc -drive file=/root/images/RHEL6.1_64-copy.qcow2,if=none,id=drive-ide-0-0,media=disk,format=qcow2,cache=none,werror=stop -device ide-drive,drive=drive-ide-0-0,id=ide0-0-0 -netdev tap,id=hostnet1 -device e1000,netdev=hostnet1,id=net1,mac=64:31:50:46:22:36 -usb -device usb-tablet,id=input1 -spice port=9000,disable-ticketing -monitor stdio -balloon none Verified this issue with e1000 with same steps mentioned above with qemu-kvm-0.12.1.2-2.177.el6.x86_64 After step 3: netperf clients can be launched and work well, no abnormal error pops up. ----CLI: /usr/libexec/qemu-kvm -M rhel6.2.0 -enable-kvm -m 4096 -smp 2 -name RHEL6.1_64 -uuid `uuidgen` -rtc base=utc,clock=host,driftfix=slew -boot dc -drive file=/root/images/RHEL6.1_64-copy.qcow2,if=none,id=drive-ide-0-0,media=disk,format=qcow2,cache=none,werror=stop -device ide-drive,drive=drive-ide-0-0,id=ide0-0-0 -netdev tap,id=hostnet1 -device e1000,netdev=hostnet1,id=net1,mac=64:31:50:46:22:36 -usb -device usb-tablet,id=input1 -spice port=9000,disable-ticketing -monitor stdio -balloon none ---conclusion: Based on above, this issue has been fixed correctly. Hit this bug in weekly testing: kernel-2.6.32-207.el6.x86_64, qemu-kvm-0.12.1.2-2.196.el6.x86_64 So reopen it.

Error code returns from netserver to netperf. # grep -i 'interrupted system call' /usr/include/ -r /usr/include/asm-generic/errno-base.h:#define EINTR 4 /* Interrupted system call */ This request was not resolved in time for the current release. Red Hat invites you to ask your support representative to propose this request, if still desired, for consideration in the next release of Red Hat Enterprise Linux. This request was erroneously removed from consideration in Red Hat Enterprise Linux 6.4, which is currently under development. This request will be evaluated for inclusion in Red Hat Enterprise Linux 6.4. So this if you like is bufferbloat in action. Not triggerable easily ith virtio because it is much faster but may affect virtio under lots of stress. Fix might need risky changes so let's try to address in rhel7. *** Bug 771866 has been marked as a duplicate of this bug. *** Closing. We deferred it for too long. will never get to it. |
