Hi all,

I have a problem now, I've never had before. All my Linux guests,
block the boot process at the "Sending DHCP requests ..." message.
The DHCP server works, since all my physical machines get an IP address
every time. This also worked for XEN guests, up to few days ago.

I read this discussion
(http://lists.xensource.com/archives/html/xen-devel/2005-09/msg00319.html)
but it doesn't solve my problem.

These are the boot messages I get before the boot process lock:

[    3.044520] Netfilter messages via NETLINK v0.30.
[    3.044535] nf_conntrack version 0.5.0 (4160 buckets, 16640 max)

[    4.549105] Sending DHCP requests ...
[   18.851032] .


The configuration file is the following:
kernel = "/mnt/xen/kernel/vmlinuz-xen-2.6.31-r7-domU"
memory = "512"
name = "gentoo-10.0-x86_64"
vif = ['bridge=xenbr0']
dhcp = "dhcp"
disk = ['file:/mnt/vmstore/gentoo-10.0/gentoo-10.0.x86-64.img,hda1,w']
root = "/dev/hda1 ro"
vcpus = 2
extra   = 'console=hvc0 xencons=tty'


I am on a Gentoo Host system and I have many different Linux guest
distributions.
All Linux distributions give me that problem.

I don't know if it could depend on the kernel configuration, but I guess no,
since it worked before, and I didn't change anything.

My host and guest kernel is 2.6.31-r7.

Any help will be appreciated.

Thanks a lot,

Flavio
