[Bug 1297218] [NEW] guest hangs after live migration due to tsc jump
Public bug reported: We have two identical Ubuntu servers running libvirt/kvm/qemu, sharing a Gluster filesystem. Guests can be live migrated between them. However, live migration often leads to the guest being stuck at 100% for a while. In that case, the dmesg output for such a guest will show (once it recovers): Clocksource tsc unstable (delta = 662463064082 ns). In this particular example, a guest was migrated and only after 11 minutes (662 seconds) did it become responsive again. It seems that newly booted guests doe not suffer from this problem, these can be migrated back and forth at will. After a day or so, the problem becomes apparent. It also seems that migrating from server A to server B causes much more problems than going from B back to A. If necessary, I can do more measurements to qualify these observations. The VM servers run Ubuntu 13.04 with these packages: Kernel: 3.8.0-35-generic x86_64 Libvirt: 1.0.2 Qemu: 1.4.0 Gluster-fs: 3.4.2 (libvirt access the images via the filesystem, not using libgfapi yet as the Ubuntu libvirt is not linked against libgfapi). The interconnect between both machines (both for migration and gluster) is 10GbE. Both servers are synced to NTP and well within 1ms form one another. Guests are either Ubuntu 13.04 or 13.10. On the guests, the current_clocksource is kvm-clock. The XML definition of the guests only contains: clock offset='utc'/ Now as far as I've read in the documentation of kvm-clock, it specifically supports live migrations, so I'm a bit surprised at these problems. There isn't all that much information to find on these issue, although I have found postings by others that seem to have run into the same issues, but without a solution. ** Affects: libvirt (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to libvirt in Ubuntu. https://bugs.launchpad.net/bugs/1297218 Title: guest hangs after live migration due to tsc jump To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1297218/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 1040177] Re: slapd install fails when requesting to 'Omit OpenLDAP server configuration
I would say that the 'old' behaviour would be preferable if somoene choses to have an unconfigured slapd: Instead of failing to start the service, an empty slapd that is live and can be configured from the root account would be a bit more user-friendly. This seems to be how slapd was packaged in Ubuntu before, until the addition of an automatically populated tree recently. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openldap in Ubuntu. https://bugs.launchpad.net/bugs/1040177 Title: slapd install fails when requesting to 'Omit OpenLDAP server configuration To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openldap/+bug/1040177/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
