test with kvm-83-117.el5, cannot reproduce this problem. 1. start guest by: /usr/libexec/qemu-kvm -rtc-td-hack -no-hpet -usbdevice tablet -cpu qemu64,+sse2 -drive file=RHEL-Server-5.4-64-virtio.qcow2,if=ide -smp 2 -m 2G -name rhel54-64 -net nic,macaddr=20:20:20:11:42:66,model=i82551,vlan=0 -net tap,script=/etc/qemu-ifup,vlan=0 -vnc :2 2. tranfer some files to guest from remote host. 3. run netperf for 10 min. Actual results: after 1 hour, guest works fine. Test with kvm-83-139.el5, come across that qemu aborted when run "service network restart" for one time. steps: 1. boot guest with e1000 nic: /usr/libexec/qemu-kvm -rtc-td-hack -no-hpet -usbdevice tablet -cpu qemu64,+sse2 -drive file=rhel5u4-64-virtio.qcow2,if=virtio,boot=on,format=qcow2,cache=off -smp 2 -m 2G -vnc :2 -net nic,macaddr=20:20:20:11:00:91,model=e1000,vlan=0 -net tap,script=/etc/qemu-ifup,vlan=0 -monitor stdio 2. shutdown guest 3. boot guest with i82551 nic: /usr/libexec/qemu-kvm -rtc-td-hack -no-hpet -usbdevice tablet -cpu qemu64,+sse2 -drive file=rhel5u4-64-virtio.qcow2,if=virtio,boot=on,format=qcow2,cache=off -smp 2 -m 2G -vnc :2 -net nic,macaddr=20:20:20:11:00:91,model=i82551,vlan=0 -net tap,script=/etc/qemu-ifup,vlan=0 -monitor stdio 4. In guest: cd /etc/sysconfig/network-scripts/ mv ifcfg-eth0.bak ifcfg-eth0 service network restart Actual result: (qemu) qemu-kvm: /builddir/build/BUILD/kvm-83-maint-snapshot-20090205/qemu/hw/eepro100.c:1573: nic_receive: Assertion `0' failed. Aborted michen->nsprei: could you please help to check this issue? i cannot reproduce it any more. I can reproduce the issue, consistently, using qemu built out of latest git version of rhel, using guest rhel 5.3 64bit. I think it's a different issue than this one. Shouldn't it be a new/different bug ?
