guest console output

Description of problem:
Booting IA64 RHEL4.9 HVM guest with ioemu nic rtl8139 or e1000, the guest
stops responding at "Bringing up interface eth0 ...", while netfront works
fine.

Version-Release number of selected component (if applicable):
host:
kernel-xen-2.6.18-267.el5
xen-3.0.3-132.el5
guest:
kernel-largesmp-2.6.9-101.EL
kmod-xenpv-largesmp-0.1-17.el4

How reproducible:
Always

Steps to Reproduce:
1. add the ioemu vnif to HVM guest config.

vif = ['mac=00:21:7F:B7:08:04,script=vif-bridge,bridge=xenbr0,type=ioemu,model=rtl8139']

2. boot the pre-installed RHEL 4 guest.

Additional info:
This issue seems introduced by the fix for bug 663537.
The kmod-xenpv-0.1-11.el4 works for ioemu but not for netfront.

We'll have to check other versions between -11 and -17. The patch for bug 663537 touches nothing but "xenpv/linux-2.6-xen-sparse/drivers/xen/netfront/netfront.c". The separate kmod-xenpv package doesn't even need to be installed on the system.

/var/log/message from guest

There are a lot of "ifup: interface 'dev????' not found" in the message.

During waiting for the guest bringing up the eth0, `xm top` from dom0 shows that the guest CPU usage is >= 100%.
