[Xen-users] virtual network hangs during a file download

["Christopher Isip" <cmisip@xxxxxxxxx>]

I just managed to get xen 3.2 up and running in Centos 5.1.  I installed the rpms from xen.org (first the xen 3.1 then 3.2 rpms)

my grub setting in dom0 is
title CentOS (2.6.18-xen_3.2.0)
        root (hd0,5)
        kernel /boot/xen.gz-3.2
        module /boot/vmlinuz-2.6-xen ro root=LABEL=/ rhgb quiet
        module /boot/initrd-2.6-xen.img

where vmlinuz-2.6-xen is a symlink to vmlinuz-2.6.18-xen_3.1.0
and initrd-2.6-xen.img is a symlink to initrd-2.6.18-xen_3.1.0.img

I assumed this is the way its supposed to be done with xen 3.2 kernel booting the 3.1 vmlinuz and initrd images.

I got a domU Centos-Asterisk up and running using a e100 pci card, hidden from dom0 with pciback.
Its settings are:
name = "Centos-Asterisk"
maxmem = 512
memory = 512
vcpus = 1
bootloader = "/usr/bin/pygrub"
>>>
vfb = [  ]
disk = [ "tap:aio:/vm/Centos-Asterisk.img,xvda,w" ]
vif = [ 'mac=00:16:3e:70:21:02,bridge=peth0' ]
pci = [ '0000:03:08.0' ]

The domU boots fine and negotiates an IP from my ISP using eth0 ( the pci card ) and then connects eth1 (virtual interface) to the bridge peth0 in dom0.
Everything works fine  (all other clients in the network and other domU's can connect  and yum installs even work)  except when I try to download a file in dom0 , it will work for a little while and then hangs.  The domU is still connected to the internet but it cannot ping dom0.  Dom0 cannot ping domU as well.

As I said, I have just began to test the domU.  This behavior repeats each time I try to download anything using Dom0.  I have yet to try if I can reproduce the hang with other network clients.   

Any help is appreciated.

Thanks
Chris
