Ok I have built a test kernel containing the missing patch above which is here:
http://people.canonical.com/~apw/hyperv-saucy/ I have also attempted to add the required rule to udev which is here: http://people.canonical.com/~apw/hyperv-saucy/udev/ If you could test those and confirm that this combination works as expected. Please note I have made some changes to the udev rule to firstly make it use modern ATTR manipulation, and secondly to only apply it for hyper-v guests. Please report any testing back here. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1233466 Title: Hot-Add Memory failing for lack of udev rule Status in “linux” package in Ubuntu: Fix Committed Status in “systemd” package in Ubuntu: In Progress Bug description: It appears that the Hot-Add mechanism is not working because of lack of a udev rule.
