Hello,
We are experiencing a very strange networking problem with the open
source version of Xen. The host OS was CentOS 5.1, but I believe it has
been patched to the latest version. We are using the Xen virtualization
that ships with CentOS. The Ubuntu guest VM is running 7.1.2008
When the Ubuntu guest VM boots up, it exhibits the following behavior:
The VM can ping its default gateway
The VM can ping remote hosts by IP address
The VM can run nslookup, connect to both local and remote DNS servers,
and successfully resolve names (so, UDP is working...)
The host OS can SSH into the VM (both are on the same logical subnet)
The VM can SSH into the host OS
The VM cannot do any kind of TCP based connections to hosts other than
the host OS. We have tried FTP, HTTP, and SSH. It should also be noted
that we attempted to perform an installation of a CentOS 5.1 VM using
the CD to boot and then selecting HTTP and FTP downloads from known
mirrors. These TCP transactions also failed, so the problem doesn''t
appear to be specific to the Ubuntu VM.
I ran a tcpdump of the virtual bridge interface and I can see outbound
TCP connections and the return traffic. But for some reason the return
traffic isn''t being passed on to the VM. I tried disabling IPTables on
the host OS and that didn''t impact anything.
It should also be noted that Xen worked perfectly on another CentOS 5.1
server. The problem is showing up only on some new SuperMicro servers
that my customer purchased.
Any help would be greatly appreciated!
Here is the uname -an output of the host OS:
Linux sf-prod-host2.keystream.com 2.6.18-92.1.6.el5xen #1 SMP Wed Jun 25
14:13:10 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux
Here is the Xen config file:

Here is the test.cfg file used to launch the VM:

ramdisk = ''/boot/initrd.img-2.6.22-14-xen''

on_poweroff = ''destroy''
on_reboot = ''restart''
on_crash = ''restart''
extra = ''xencons=tty''
I don''t see any network related error messages in the xend log file.
Here is the output of the console when starting the VM:
