[Bug 1564831] Re: s390x: error booting instance
Regarding issue 2), this is most probably due to the cpu mode setting: The nova.conf needs the setting "cpu_mode = none" in order to not have it set to 'host-model'. This setting has not been working on s390x - this is a statement as of Mitaka and libvirt 1.2.21 at least -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to nova in Ubuntu. https://bugs.launchpad.net/bugs/1564831 Title: s390x: error booting instance To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1564831/+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

Also tried with the nova-compute node running directly on Ubuntu on an LPAR but still see the same problem.. I think there are two distinct bugs here 1) lxcfs support for S390x looks a little incomplete 2) nova can't boot KVM instances with mitaka + libvirt 1.3.1 -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to nova in Ubuntu. https://bugs.launchpad.net/bugs/1564831 Title: s390x: error booting instance To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1564831/+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

Should have also mentioned that this is running in a LXD container; /proc/cpuinfo is empty for some reason which I think is the root cause of this problem. ** Also affects: lxd (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to nova in Ubuntu. https://bugs.launchpad.net/bugs/1564831 Title: s390x: error booting instance To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1564831/+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
