DHCP problem when discovering new bare-metal servers
I´m having some problems with my new ICELX and I hope you could give me some info.
I'm using a XEN environment and both the server and the CMS are virtual machines. Maybe it could be important.
Anyway, I post the problem:
The server boots normally within the PXE, detects the DHCP, receive the ram disk image from the tftp and once it has boot almost completely starts to try to locate the dhcp server again looking for an ip for the nic. The problem, and it´s really amazing for me is that the server tries to locate the dhcp throught the loopback, and obviouslly nobody answers.
The message is the following:
DHCPDISCOVER on lo to 255.255.255.255 port 67 interval x (it repeats some times the same message)
NO DHCP OFFERS RECEIVED
No working leases in persistent detabase - sleeping.
I couldn´t configure the network interface using DCHP
Killing off running processes
... and prompt
I'm going to try with physical servers when I can get one but if anyone has some info i will thank you.

Re: DHCP problem when discovering new bare-metal servers
The DCHP server is either down, not configured or not on the network.
That is the source of the problem.

Re: DHCP problem when discovering new bare-metal servers
The DHCP is working perfectly since the server can boot from PXE, load the RAM disk image and complete all the steps. The server only has one nic enabled so if the server answers to the DHCP/PXE request once, there is no reason to think it wouldn't do it again.
I have been investigating deeper and I have discovered that the server (remember that is a Xen virtual machine) doesn´t load the nic drivers when it boots from the RAM disc kernel so the only interface available is the loopback. This answer my first question but generates a new one.. Is this due to I´m using a VM and the kernel is not compatible? I suppose it will use generic-Linux drivers so...
Any ideas?
Thanks
