I just tried this with a RHEL5 guest running libvrit-0.8.2-15.el5, and it behaves as expected. If the guest's libvirt is configured with the same default network as the host's libvirt, when you start libvirtd in the guest, /var/log/messages will show the following message: networkCheckRouteCollision:1110 : internal error Network 192.168.122.1/255.255.255.0 is already in use by interface eth0. The default network on the guest libvirtd is not started, and the guest is still able to contact the outside. If I then run "virsh net-start default", I get the same error message from virsh, and the default network is still not started. Can you please verify that: 1) the *guest* is running libvirtd-0.8.2-15.el5 2) "virsh net-dumpxml default" on the host and guest are the same 3) reboot the guest 4) verify the guest can reach the outside (eg "ping ftp.uu.net") 5) check for network connectivity in the guest, and look for the error message I mention above in /var/log/messages. 6) start libvirtd and check all that again. If you still get the same results we need to investigate further. (In reply to comment #2) I tried with RHEL5.6-Server-x86_64-kvm,rc 1.0 tree. A guest running libvirt-0.8.2-15.el5. According to steps in comment 1, this bug can not be reproduced.All ping are successful in step 4, and an error will display when #virsh net-start default in guest. So I will close this bug. |
