Ok, so Lucid needs some more investigation. What you do is basically writing 0/1 into /sys/devices/cpu/cpu?/online, right?
For Natty I have prepared some test kernels at: http://people.canonical.com/~smb/lp1007002/ I did a quick offline/online of one CPU and a save/restore on 32bit. This looked ok. Could you give it a try as well? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1007002 Title: Xen VCPUs hotplug does not work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1007002/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
