Sorry for the lack of response, but F14 is no longer supported. Muzi, if you are still affected by this bug with newer qemu versions (fedora 16 or 17), please reopen this report. |
Description of problem: i have fully virutalized guest with 2 NIC's eth0 is working but eth1 is receiving packets not transmitting data and functional due to facing shares both an interrupt and memory access address with usb device Version-Release number of selected component (if applicable):0.12.5-1 How reproducible: Steps to Reproduce: 1. Run VM with two NIC's support 2. On Child up both eth0 and eth1 3. eth1 not working , interrupts detail mention in Additional info Actual results: eth1 is just receiving data not transmitting data Expected results: eth1 should be work Additional info: cat /proc/interrupts CPU0 0: 219 IO-APIC-edge timer 1: 6 IO-APIC-edge i8042 4: 88 IO-APIC-edge serial 8: 1 IO-APIC-edge rtc0 9: 0 IO-APIC-fasteoi acpi 10: 32173856 IO-APIC-fasteoi eth0 11: 331891 IO-APIC-fasteoi uhci_hcd:usb1, eth1 As see in 11: eth1 shares interrupts with usb device. Both eth0 and eth1 using same NIC model as see below cat /etc/udev/rules.d/70-persistent-net.rules # Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rule written by anaconda) # PCI device 0x10ec:0x8139 (8139cp) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="52:54:00:5f:6e:d3", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0" # PCI device 0x10ec:0x8139 (8139cp) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="52:54:00:d1:fc:ae", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1" Please suggest, how we will functional eth1 ? Thanks Muzi
