Possible solution: echo "1" > /proc/sys/net/ipv4/ip_forward on Host. To make things permanent in /etc/sysctl.conf net.ipv4.ip_forward = 1 This bug remains in Fedora 7 gold release. Do we see any possible permanent solution other than the ip_forward trick done manually. Thanks. The libvirt daemon does enable ip_forward whenever a virtual network is created. There is one network defined automatically upon RPM installation, so libvirt is normally enabling ip_forward right away. Now the /etc/sysctl.conf file also has an explicit rule to disable ip_forward, but this file is loaded by the 'network' init script prior to libvirt running so its not ordinarily a problem. Except that I just discovered NetworkManager's init script will load sysctl.conf *again* overiding what libvirt changed :-( Hi, Today I installed the new libvirt 0.2.3 on Fedora 7. And I booted a live cd from within virt-manager (using KVM). And it booted well also the ip forwarding thing seem to have worked though I didn't had ip_forward in the host. I was able to access internet from within the live cd guest (192.168.122.0/24) network. That means this bug is solved or it means something else ? Thanks Hi, just want to report that I am seeing the same problem. After I enable ip_forward in /etc/sysctl.conf and reboot, networking working. My guest OS is a Win XP SP2. This problem is still there in Rawhide on 1/19/08 (6 months later). At a minimum, virt-manager should pop up a warning that guest networking will fail without ip_forward set. This problem is still present in the Fedora 9 preview release (27/04/2008), almost 12 months after the issue was reported. As this issue is impacting every user that is running KVM this has a high impact and really should be fixed asap. *** Bug 371571 has been marked as a duplicate of this bug. *** Changing version to '9' as part of upcoming Fedora 9 GA. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping This is still a problem in Fedora 9. Although there are also other networking bugs I will report separately. This message is a reminder that Fedora 9 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 9. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '9'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 9's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 9 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Hi all. Can you still see this issue? I do not see it now in F10, but I'm not sure if I have configured something in the past of it just started to work. I have not seen this bug anymore since F10. Virtual networks set up with virt-manager now work out of the box. Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed. |
