[Bug 1001798] Re: Remote TLS connection to Libvirt 0.9.8 hangs (possibly a race condition and very possibly a regression)
After my last comment here over two years ago I haven't had the time and resources to debug this any more than I already had at that point. We have since switched to using unencrypted Libvirt connections (qemu+tcp:///) which is good enough since all virtualisation hosts are on a separate and secure management subnet and VLAN. But I just tried the qemu+tls:/// connections again just now, to six different virtualisation hosts and I *can't* reproduce this problem any more. The hosts are all running Ubuntu 12.04.5, some with the Trusty HWE kernel (e.g. 3.13.0-40-generic), some with the original Precise kernel (e.g. 3.2.0-74-generic). Libvirt is installed in version 0.9.8-2ubuntu17.20. The Libvirt client in all cases is also a Ubuntu 12.04.5 machine, also running Libvirt 0.9.8-2ubuntu17.20. We currently also leverage our Puppet CA and use the issued certificates not only for Puppet but also for Libvirt and other services. I don't think this makes a difference but two years ago when I ran into this problem we were using keys and certificates issued by our own internal CA. So to me this looks resolved but since I have no idea what caused the problem originally and what exactly has changed in Libvirt since then in that regard I can only really say WORKSFORME. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1001798 Title: Remote TLS connection to Libvirt 0.9.8 hangs (possibly a race condition and very possibly a regression) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1001798/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Testing some combinations - using a quantal server, a quantal client can do virsh -c qemu+tls://guest/server list just fine. A precise client usually works, but occasionally gives a warning as shown below.

[Bug 1001798] Re: Remote TLS connection to Libvirt 0.9.8 hangs (possibly a race condition and very possibly a regression)
It's funny. I have three machines where I can always reproduce the behaviour in my original description and two machines where I can connect and list just fine. All running Precise. The two where it works are slightly newer, i.e. have been set up some time in the last two months, whereas the others are from May or so. Otherwise the machines are identical PowerEdge R710s. Around the same number of VMs, same CPUs, amount of RAM, network configuration, etc. I don't know if it makes any difference in these tests, but it seems you have no VMs running on your virtualisation host. Maybe add some? It may also be noteworthy that our VMs' disks are all LVM-based, which is why we are also bitten by bug #1027987. I wouldn't want to presume anything but maybe there is some relation between this bug and that. Unfortunately I still need some time before I can test any of this out on some spare machines running Quantal. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1001798 Title: Remote TLS connection to Libvirt 0.9.8 hangs (possibly a race condition and very possibly a regression) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1001798/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@Andreas, I ran that test case on precise for 3.5 hours, with virtio network bridged with eth0 and without the vhost_net kernel module loaded, but network never hung. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1001798 Title: Remote TLS connection to Libvirt 0.9.8 hangs (possibly a race condition and very possibly a regression) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1001798/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1001798] Re: Remote TLS connection to Libvirt 0.9.8 hangs (possibly a race condition and very possibly a regression)
Thanks. In your case, is the client also 12.04? An incompatibility between oneiric guests and precise hosts has been reported recently (hence marking this confirmed). If precise guests also cause a problem, that is new to me and good to know. ** Changed in: libvirt (Ubuntu) Status: New = Confirmed ** Changed in: libvirt (Ubuntu) Importance: Undecided = Medium ** Changed in: libvirt (Ubuntu) Importance: Medium = High -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1001798 Title: Remote TLS connection to Libvirt 0.9.8 hangs (possibly a race condition and very possibly a regression) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1001798/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

In my case, the client was indeed 12.04, but I just tested with a 10.04 client (0.9.2-5ubuntu0+dnjl0~lucid0, from https://launchpad.net/~dnjl/+archive/virtualization) and the problem is the same.
