Re: [Xen-users] Guests stops at "Sending DHCP requests ..."

[Geert Janssens <info@xxxxxxxxxxxx>]

This may not be related to your problem, but I'll mention it anyway.

I had some DHCP problems a while ago as well. DomU's would not receive their 
ip address, while physical hosts did.

In my case it turned out that I hadn't configured my DHCP server as 
authoritative (this is an option in the dhcpd.conf file). After setting that 
parameter, everything worked fine. 

Did you check your dhcpd log already (on CentOS this is logged to 
/var/log/messages) ? Is the dhcpd server receiving the requests ? If not, it's 
definitely another problem than mine...
