snapshot of installing guest
When I install guest from cdrom, it fails to setup network.
Does it related this bug ?
[root@intel-5310-32-1 kvm]# rpm -qa |grep qemu
qemu-img-0.12.1.2-2.131.el6.x86_64
qemu-kvm-0.12.1.2-2.131.el6.x86_64

[root@intel-5310-32-1 kvm]# uname -r
2.6.32-103.el6.x86_64
To comment 3: No, install from cdrom runs regular guest drivers, not pxe. Hi,rvaknin I can not reproduce it in my environment.Could you help to verify it ?

Created attachment 475166 [details] pcaps VM with virtIO NIC can't access the PXE server, it reaches a time out: tftp://10.35.16.92/pxelinux.0............. Connection timed out (0x4c126035) By sniffing the VM's traffic, it seems that the VM get an IP from the DHCP server but still can't reach its own default gateway, the default gateway doesn't answer to the ARP requests. The ARP requests that the VM sends are too big (1514 byte, while a regular DHCP Discover is around 60 bytes) and not valid, so the default gateway does not answer to those ARP requests. Version-Release number of selected component (if applicable): kernel: 2.6.32-71.el6.x86_64 qemu-kvm-0.12.1.2-2.129.el6.x86_64 Steps to Reproduce: 1. Define a new VM with PXE boot and virtIO NIC Additional info: Note that there is no problem when booting the same machine with Fedora's live CD - the networking works well. Also, when using the e1000 or rtl8139 network interfaces with boot to PXE, the connection to the PXE works well. 17:00:52.562254 ARP, Request who-has 10.35.99.254 tell 10.35.99.4, length 1500 The MAC address of the VM is 00:1a:4a:16:99:04. /var/log/libvirt/qemu/RHEL6_3.log: LC_ALL=C PATH=/sbin:/usr/sbin:/bin:/usr/bin QEMU_AUDIO_DRV=none /usr/libexec/qemu-kvm -S -M rhel6.0.0 -cpu Penryn -enable-kvm -m 512 -smp 1,sockets=1,cores=1,threads=1 -name RHEL6_3 -uuid 26283ecd-0146-4710-963e-5ba078726893 -nodefconfig -nodefaults -chardev socket,id=monitor,path=/var/lib/libvirt/qemu/RHEL6_3.monitor,server,nowait -mon chardev=monitor,mode=control -rtc base=2011-01-20T14:19:41 -boot n -device virtio-serial-pci,id=virtio-serial0,max_ports=16,bus=pci.0,addr=0x4 -drive file=/rhev/data-center/1af052ad-9b2c-4fa7-b445-9d64c71511ac/9469f758-2e7c-44d3-875a-b85a34bf841c/images/aa3b10a2-3de3-47a7-baf2-c3c3ff788d18/1b0a07db-38c8-48ad-865d-b351277782fa,if=none,id=drive-virtio-disk0,format=qcow2,serial=a7-baf2-c3c3ff788d18,cache=none,werror=stop,rerror=stop -device virtio-blk-pci,bus=pci.0,addr=0x5,drive=drive-virtio-disk0,id=virtio-disk0 -drive if=none,media=cdrom,id=drive-ide0-1-0,readonly=on,format=raw -device ide-drive,bus=ide.1,unit=0,drive=drive-ide0-1-0,id=ide0-1-0 -netdev tap,fd=23,id=hostnet0 -device virtio-net-pci,netdev=hostnet0,id=net0,mac=00:1a:4a:16:99:04,bus=pci.0,addr=0x3 -chardev socket,id=channel0,path=/var/lib/libvirt/qemu/channels/RHEL6_3.com.redhat.rhevm.vdsm,server,nowait -device virtserialport,bus=virtio-serial0.0,nr=0,chardev=channel0,name=com.redhat.rhevm.vdsm -usb -device usb-tablet,id=input0 -vnc 0:2,password -k en-us -vga cirrus
