I have no idea why, but the problem corrected itself overnight. Something, either in Fedora, the router, Comcast or somewhere must have run and fixed the problem. I have no idea how. <div class="gmail_quote">On Jan 8, 2008 8:21 AM, Dustin Henning < <a href="mailto:Dustin.Henning@prd-inc.com">Dustin.Henning@prd-inc.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> When the xend service starts, it creates bridges and virtual interfaces attached to those bridges. I am not so familiar with it to tell you how to correct your problem on a permanent basis, but I can tell you that perhaps the network script isn't preserving your routes. Check your routes and see if a default route to the Linksys still exists. It also seems to me like F8 may use a different default xen network script, so depending on what you want to do, you many need to change the network script in xen's config file. This advice may be legacy, as I know Fedora's implementation gets more and more custom with each release, and I generally fall back on old xen configuration techniques in spite of that, so this may not be the route you want to take.

(Besides, wouldn't they use the same configuration files at boot time?) My problem is, when I boot with the xen kernel, I can't get out through my router. I can ping everything on my eth0 or eth1 networks, just not go through my eth0 Linksys router. The only difference I've been able to see is that something called "peth0" uses the same card as the NIC my router is on. Is this getting in the way somehow? eth0 Link encap:Ethernet HWaddr 00:17:31:01:C8:A8 inet addr:<a href="http://192.168.1.151" target="_blank">192.168.1.151</a> Bcast:<a href="http://192.168.1.255" target="_blank">192.168.1.255</a> Mask:<a href="http://255.255.255.0" target="_blank">255.255.255.0</a> inet6 addr: fe80::217:31ff:fe01:c8a8/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:10 errors:0 dropped:0 overruns:0 frame:0 TX packets:47 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:494 (494.0 b) TX bytes:6566 (6.4 KiB) eth1 Link encap:Ethernet HWaddr 00:17:31:01:D0:20 inet addr:<a href="http://192.168.0.3" target="_blank">192.168.0.3</a> Bcast:<a href="http://192.168.0.255" target="_blank"> 192.168.0.255</a> Mask:<a href="http://255.255.255.0" target="_blank">255.255.255.0</a> inet6 addr: fe80::217:31ff:fe01:d020/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:29 errors:0 dropped:0 overruns:0 frame:0 TX packets:63 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:2412 (2.3 KiB) TX bytes:8491 (8.2 KiB) Interrupt:23 Base address:0xe000 lo Link encap:Local Loopback inet addr: <a href="http://127.0.0.1" target="_blank">127.0.0.1</a> Mask:<a href="http://255.0.0.0" target="_blank">255.0.0.0</a> inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:8504 errors:0 dropped:0 overruns:0 frame:0 TX packets:8504 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:10008668 (9.5 MiB) TX bytes:10008668 (9.5 MiB) peth0 Link encap:Ethernet HWaddr 00:17:31:01:C8:A8 inet6 addr: fe80::217:31ff:fe01:c8a8/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:53 errors:0 dropped:0 overruns:0 frame:0 TX packets:121 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:5414 (5.2 KiB) TX bytes:14547 ( 14.2 KiB) Interrupt:18 virbr0 Link encap:Ethernet HWaddr 00:00:00:00:00:00 inet addr:<a href="http://192.168.122.1" target="_blank">192.168.122.1</a> Bcast:<a href="http://192.168.122.255" target="_blank">192.168.122.255 </a> Mask:<a href="http://255.255.255.0" target="_blank">255.255.255.0</a> inet6 addr: fe80::200:ff:fe00:0/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:32 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:5156 (5.0 KiB) Thanks, -- Jack Smith English doesn't borrow from other languages -- English follows other languages down dark alleys and takes what it wants. </div></div></blockquote></div> -- Jack Smith English doesn't borrow from other languages -- English follows other languages down dark alleys and takes what it wants.
