Public bug reported: [Impact]
When using KVM, if one suspends the VM using actual power suspending code, the guest cannot resume using 'virsh dompmwakeup'. [Test Case] 1) Create a KVM VM and install Trusty using libvirt (although qemu alone will also exhibit this problem) 2) Inside the vm run (as root): 'echo mem > /sys/power/state' 3) From the hypervisor run 'virsh dompmwakeup <domain name>' 4) The domain should resume So far I've noticed that on Utopic this works fine, while on Trusty this fails; a bisect is needed. ** Affects: linux (Ubuntu) Importance: Undecided Status: Fix Released ** Affects: linux (Ubuntu Trusty) Importance: Medium Assignee: Chris J Arges (arges) Status: In Progress ** Also affects: linux (Ubuntu Trusty) Importance: Undecided Status: New ** Changed in: linux (Ubuntu Trusty) Assignee: (unassigned) => Chris J Arges (arges) ** Changed in: linux (Ubuntu) Status: In Progress => Fix Released ** Changed in: linux (Ubuntu) Assignee: Chris J Arges (arges) => (unassigned) ** Changed in: linux (Ubuntu Trusty) Status: New => In Progress ** Changed in: linux (Ubuntu Trusty) Importance: Undecided => Medium ** Changed in: linux (Ubuntu) Importance: Medium => Undecided -- 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/1366868 Title: kvm: dompmwakeup fails if domain becomes pmsuspended Status in “linux” package in Ubuntu: Fix Released Status in “linux” source package in Trusty: In Progress Bug description: [Impact] When using KVM, if one suspends the VM using actual power suspending code, the guest cannot resume using 'virsh dompmwakeup'.
