After booting up, use “dhclient ethX” to get IP (we use DHCP in the network), guest can not get IP. Note: 1. UP guest(-smp 1) doesn’t have this issue. 2. Windows(e.g. Win7) guest(-smp 4) has no issue. This should be a qemu-kvm bug. kvm + qemu-kvm = result 25e531a9 + 0a948cbb = bad 25e531a9 + 18b01275 = good Reproduce steps: ---------------- 1.start up a host with kvm(25e531a9) + qemu-kvm (0a948cbb) 2.qemu-system-x86_64 -m 1024 -smp 4 –net nic,model=rt18139 –net tap,script=/etc/kvm/qemu-ifup –hda /root/rhel6u1.qcow 3. ifconfig 4. ping 192.168.199.98 (a IP in the same subnet) 5. dhclient ethx (can't get dynamic IP address) Current result: ---------------- The guest can not get IP Expected result: ---------------- The guest get IP and work fine.
