Hello, After running a bisect between tags libnl3_2_21 and libnl3_2_22 I identified the fixer commit to be 807fddc nl: Increase receive buffer size to 4 pages
commit 807fddc4cd9ecb12ba64e1b7fa26d86b6c2f19b0 Author: Thomas Graf <[email protected]> Date: Wed May 8 13:52:27 2013 +0200 nl: Increase receive buffer size to 4 pages Assuming that the kernel does not send more than a page is no longer valid, and enabling MSG_PEEK'ing by default to figure out the exact message buffer requirements can have a negative influence on the performance of existing applications. Bumping the default receive buffer space to 4 pages seems a sane default. Signed-off-by: Thomas Graf <[email protected]> --- After applying this patch on top of the current trusty-updates this problem is not longer exhibited and I can attach the full 128 VFs to the guest. I am proposing this patch for SRU, and I already updated the description with the reproduction steps. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1567578 Title: libnl should be updated to support up to 63 VFs per single PF To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libnl3/+bug/1567578/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
