Category: None Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Paul Donohue (paulsd) Assigned to: Nobody/Anonymous (nobody) Summary: kvm init script breaks network interfaces with multiple IPs Initial Comment: If multiple IP addresses are assigned to a network interface (Using interface aliases - for example 'ifconfig eth0 10.0.0.1 ; ifconfig eth0:1 10.0.0.2'), then the kvm init script causes the interface to become unresponsive when it creates a bridge using the interface. I haven't yet had a need to use bridging for my VMs, so I haven't yet tried to figure out how to properly configure a bridge when multiple IPs are in use on the host system (I assume the multiple IPs simply need to be configured using aliases of the bridge itself - for example 'ifconfig sw0 10.0.0.1 ; ifconfig sw0:1 10.0.0.2' - but I haven't actually tried it). Therefore, I am not sure at the moment how the kvm init script needs to be updated to fix this problem. Regardless, I do have a number of machines which are using multiple IPs on the host system, and I recently installed kvm on them, then discovered that after the next reboot of each machine, the network interface is unresponsive until I disable the kvm init script and reboot again. So, ideally the kvm init script should be updated to properly handle aliased interfaces, but at the very least, it needs to be updated to detect aliased interfaces and refuse to create a bridge for them, since that seems to completely break the underlying interface. ---------------------------------------------------------------------- >Comment By: Paul Donohue (paulsd) Date: 2009-04-01 19:48 Message: Yes, it does, in the userspace tree, under the scripts subdirectory: http://git.kernel.org/?p=virt/kvm/kvm-userspace.git;a=blob;f=scripts/kvm;h=cddc931fd3b289f3c325e23b55f261e996328bd6;hb=HEAD ---------------------------------------------------------------------- Comment By: Brian Jackson (iggy_cav) Date: 2009-04-01 17:08 Message: KVM doesn't come with an init script in the tarball. This is most likely provided by your distro or some other third party. You should contact them for support. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=893831&aid=2725669&group_id=180599 -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
