Description Itamar Reis Peixoto 2011-12-12 19:49:11 UTC

Description of problem:

I am running 4-5 kvm guests in fedora 16 and I am seeing out of buffer space in guests.

I have inscreased the values bellow in the host machine and seems to be fixed the problem

net.ipv4.neigh.default.gc_thresh3 = 4096
net.ipv4.neigh.default.gc_thresh2 = 2048
net.ipv4.neigh.default.gc_thresh1 = 1024

Comment 1 Justin M. Forbes 2012-02-02 15:24:26 UTC

Can you give a bit more information about the setup? What kernel version, what qemu version, and what is the qemu command line used to start the guests?  If you are using virt-manager or virsh to start them, the command line will appear in /var/log/libvirt/qemu/<guestname>.log

You didn't really answer any of Justin's questions from comment #2.

Comment 4 Fedora End Of Life 2013-04-03 19:25:09 UTC

This bug appears to have been reported against 'rawhide' during the Fedora 19 development cycle.
Changing version to '19'.

(As we did not run this process for some time, it could affect also pre-Fedora 19 development
cycle bugs. We are very sorry. It will help us with cleanup during Fedora 19 End Of Life. Thank you.)
