Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please change the bug tag from verification-needed to verification-done. If it does not, change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Affected here on a fresh precise server install using lvm. Nice timing Andreas on creating this bug :) My interpretation of the Debian bug is that they put that workaround in their own package but were seeking a proper fix upstream (probably in the kernel).

[Bug 1027987] Re: Starting libvirtd takes too long because of udevadm settle timeout
Ryan, what you are missing out on is Libvirt being able to create volumes (LVs) in that pool (the VG) on command. I assume you create LVs manually via lvcreate and then tell Libvirt to use them for VMs? If Libvirt manages the pool you can use virt-manager, virsh or any of the APIs/bindings to talk to Libvirt and command the creation of volumes for VMs. An interesting point you brought up: we have dozens of servers running Ubuntu 12.04 for many weeks now where either this problem was not present (or not as promiment) or I simply have not noticed it consciously before. Unfortunately I can't test and experiment much since most of these servers are in production. On the servers I can experiment the problem is definitely present and noticeable. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1027987 Title: Starting libvirtd takes too long because of udevadm settle timeout To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1027987/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
