Hi I've been having trouble getting Xen setup with fedora-18. I have a bridge setup on my Dom0 called xenbr0. I have attached my primary interface on Dom0 to the created bridge. Here is my config for the bridge *ifcfg-xenbr0*. * DEVICE=xenbr0 TYPE=Bridge DNS1=172.xxx.xxx.xxx IPADDR=172.xxx.xxx.xxx GATEWAY=172.xxx.xxx.xxx NETMASK=255.xxx.xxx.xxx ONBOOT=yes BOOTPROTO=static* And here is my config file for the original interface called em1, *ifcfg-em1* * UUID=my-UUID-xxx #DNS1=172.xxx.xxx.xxx #IPADDR=172.xxx.xxx.xxx #GATEWAY=172.xxx.xxx.xxx HWADDR=00:21:9b:xx:xx:xx #NETMASK=255.xxx.xxx.xxx #BOOTPROTO=static DEVICE=em1 ONBOOT=yes BRIDGE=xenbr0* After I created the two config files I did a *service network restart* and both *em1* and *xenbr0* came up without any issues. I also updated my */etc/sysctl.conf* with the following lines to disable netfilter *net.bridge.bridge-nf-call-ip6tables = 0 net.bridge.bridge-nf-call-iptables = 0 net.bridge.bridge-nf-call-arptables = 0* And finally here is the config file I am using the to create my DomU *name="xen-testjest-2" vcpus=1 memory=1024 on_reboot='destroy' on_crash='destroy' disk=["file:/images/xen-testjest-2.img,xvda,w"] vif=["mac=00:16:3e:xx:xx:xx,bridge=xenbr0"] kernel="/images/boot/f15-installdvd-vmlinuz" ramdisk="/images/boot/f15-installdvd-initrd" extra = "text ks=http://server.with.kickstartfile/imaging/kickstart/f-15.ks <http://server.with.kickstartfile/imaging/kickstart/f-15.ks> ip=172.xxx.xxx.xxx netmask=255.xxx.xxx.xxx gateway=172.xxx.xxx.xxx dns=172.xxx.xxx.xxx"* Now the issue is when I try to run *xl create <my_config_file>* and I console in to the domain as it is being built. Everything is fine until it tries to retrieve the kickstart file from my server where my kickstart file is located. It always fails with the error *Unable to download the kickstart file*. I can download the file when I paste the url in my browser or do a wget. When I do a tcpdump at the point when it tries to retrieve the kickstart file on my Dom0 I see packets going from the my DomU to the server where my kickstart file is located. When I do a tcpdump on my server which contains the kickstart script I see packets coming in from my DomU and I also see packets being sent to DomU from my server with the ks script, but I never see any packets being received by DomU from the server with the ks file Im not really sure how to solve this problem, it seems as if my bridge is not forwarding the packets. Here is the output of my *ifconfig* * em1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 ether 00:21:xx:xx:xx:xx txqueuelen 1000 (Ethernet) RX packets 321324 bytes 157540178 (150.2 MiB) RX errors 0 dropped 3788 overruns 0 frame 0 TX packets 144519 bytes 26480182 (25.2 MiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10<host> loop txqueuelen 0 (Local Loopback) RX packets 176287 bytes 13202155 (12.5 MiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 176287 bytes 13202155 (12.5 MiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 vif6.0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet6 fe80::fcff:ffff:feff:ffff prefixlen 64 scopeid 0x20<link> ether fe:ff:ff:ff:ff:ff txqueuelen 32 (Ethernet) RX packets 36 bytes 1886 (1.8 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 10711 bytes 867595 (847.2 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 virbr0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500 inet 192.xxx.xxx.xxx netmask 255.xxx.xxx.xxx broadcast 192.xxx.xxx.xxx ether 82:76:xx:xx:xx:xx txqueuelen 0 (Ethernet) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 xenbr0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 172.xxx.xxx.xxx netmask 255.xxx.xxx.xxx broadcast 172.xxx.xxx.xxx inet6 fe80::xxxx:xxxx:xxxx:xxx prefixlen 64 scopeid 0x20<link> ether 00:21:xx:xx:xx:xx txqueuelen 0 (Ethernet) RX packets 258423 bytes 147784996 (140.9 MiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 143559 bytes 25774695 (24.5 MiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0* And here is the output of *brctl show* * bridge name bridge id STP enabled interfaces virbr0 8000.000000000000 yes xenbr0 8000.00219b98f0ae no em1 vif6.0* I have been stuck on this for a couple of days now, without making any progress. I've been searching for a solution online for some time without coming up with anything that would solve the issue I am having. Any help will be greatly appreciated :) cause this is starting to get a little bit frustrating :( - Thanks everyone _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users
