[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH] Bug-fixes for 3.15 related to 'xl shutdown' and hanging the initial domain reboot.
Hey, These patches were posted way back in Novemeber for issues discovered with Xen 4.4. I posted the patches and then dropped them to focus on PVH. Now dusting off my patch queue. The [PATCH 1/2] xen/xenbus: Avoid synchronous wait on XenBus stalling fixes an issue were initial domain would hang if it had guest running. Usually the toolstack is in charge of such things but in case that had died - well we still want to reboot but we couldn't because we were stuck waiting for a reply that we would never get. The [PATCH 2/2] xen/manage: Poweroff forcefully if user-space is not yet fixes a bit of how Linux handles the 'xl shutdown' command. In theory if the first 'xl shutdown' didn't do it - send another, and then another. Except that the kernel would gate on the first and ignore the rest. Even if it failed to shutdown. This mean the user had to destroy the guest. This patch fixes that and also makes the shutdown work when we are in the booting stage. Please pull these in stable/for-linus-3.15 after rc1.
