Please try replacing vif = [''] with
 
vif = [ 'type=ioemu, bridge=xenbr0' ]

Cheers,

Re: pcnet32 device eth0 does not seem to be present, delaying initialization

[Jonathan M. McCune]

I'm afraid I spoke too soon. 

vif = ['type=ioemu, bridge=xenbr0']
gives me an eth0 in the guest, but there is no corresponding vifX.0 in 
dom0.  Looking in /etc/xen/xmexample.hvm, I see the comment:

# type=ioemu specify the NIC is an ioemu device not netfront

I think vifX.0 is the backend, thus there is no reason for it to exist 
if the guest has no frontend.  However, what do I do instead?  I have 
been looking through documentation without luck.

Thanks!
-Jon

pcnet32 device eth0 does not seem to be present, delaying initialization

[Jonathan M. McCune]

Hi,

I'm trying to bring up an HVM guest with networking support, but I 
cannot get the guest to recognize an ethernet interface.  The guest is 
rhel5, and I'm running Debian linux dom0 on top of xen-unstable-hvm 
changeset 8724.

Running `/etc/init.d/networking restart` gives:

Shutting down loopback interface:                          [  OK  ]
Setting network parameters:                                [  OK  ]
Bringing up loopback interface:                            [  OK  ]
Bringing up interface eth0:  pcnet32 device eth0 does not seem to be 
present, delaying initialization.
                                                           [FAILED]

I have tried several stock 2.4 redhat kernels, and I have built a 2.6.12 
kernel and taken care to include the pcnet32 driver.  The config file 
for the guest domain contains the line:

vif = ['']

`lspci` inside the guest does not show any ethernet interface.

I'm not sure what to do to enable networking. 

Thanks,
-Jon
