I have noticed the same thing with KVM-87 and either the e1000 or the rtl8139 network models. I am on a 64-bit 2.6.18 RHEL 5.3 kernel with an Intel Q9300 processor.
Even statically assigning an IP to my bridged guest doesn't allow it to communicate with my network. Specifying virtio as the NIC model allows a Fedora 11 live CD to network properly. KVM-86 allows the same Fedora 11 live CD to network properly regardless of which NIC model I choose. ----- Original Message ----- From: "John Wong" <[email protected]> To: "KVM list" <[email protected]> Sent: Sunday, July 5, 2009 10:13:12 PM GMT -05:00 US/Canada Eastern Subject: Qemu 0.10.50 CAN NOT get ip from dhcp server I notice that, when i use qemu 0.10.50 (which from kvm-0.87.tar.gz), the guest OS CAN NOT get the ip from dhcp server.
