[Bug 1653499] Re: libvirt display error after restart driver
*** This bug is a duplicate of bug 1794997 *** https://bugs.launchpad.net/bugs/1794997 Clearing out old unresolved issues, this is really actually a problem within libnl more than anything else. The default should be ok (as Josh posted). I marked this a dup as there was another bug with better link references already. But the TL;DR stays as I said in comment 3 - it is non fatal and should be addressed in libnl. ** This bug has been marked a duplicate of bug 1794997 virNetlinkEventCallback:700 : nl_recv returned with error: No buffer space available -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1653499 Title: libvirt display error after restart driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1653499/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@paelzer per the description and syslog this looks to be with Mellanox cards: HCA 1: CX354A - ConnectX-3 Pro QSFP HCA 3: CX456A - ConnectX-4 QSFP HCA 4: CB192A - Connect-IB QSFP HCA 5: CX4121A - ConnectX-4 LX SFP28 Which will apparently use the mlx4 and mlx5 drivers. ** Changed in: libvirt (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1653499 Title: libvirt display error after restart driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1653499/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I'd quote something from that thread that I agree to for us I think: "Up to now our position has been that this problem should be fixed in libnl, so we have preferred to not patch libvirt for it, but instead get libnl fixed." Therefore adding libnl task. Also in the past this was very driver specific to ixgbe. >From the log snippet I only see mlx4 warnings.

[Bug 1653499] Re: libvirt display error after restart driver
Thanks for reporting this issue. nl_recv is from libnl3. Can you provide the full libvirt and syslog to see if there is any additional data that might help? Also do you have identically configured systems that are also working as expected? This message can happen when you have a number of I/O cards, especially newer ones with SRIOV capabilities that require more buffer space, but not sure if that is the case here. In Xenial the page size is set by: 682 if (page_size == 0) 683 page_size = getpagesize() * 4; ** Changed in: libvirt (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1653499 Title: libvirt display error after restart driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1653499/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
