I'm seeing a similar issue with trying to install the latest 16.04.1 i386 edition (http://releases.ubuntu.com/16.04/ubuntu-16.04.1-server-i386.iso) under libvirt/virt-manager, on an amd64 VM running 16.04.1 (4.4.0-31-generic #50-Ubuntu SMP Wed Jul 13 00:07:12 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux).
qemu-kvm hangs, have to virsh destroy/kill the KVM process. cat /etc/modprobe.d/qemu-system-x86.conf: options kvm_intel nested=1 ... and kvm-ok says acceleration is enabled. Should I open a new bug report on this ? -- 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/1448269 Title: qemu guest hangs on nested kvm startup with host kernel oops Status in linux package in Ubuntu: Fix Released Status in linux source package in Utopic: Fix Released Bug description: [Impact] Users of nested KVM may experience the L1 VM hanging when booting an L2 VM. Overall this seems to be due to issues with external interrupts not reaching L1 when L2 gets booted. [Test Case] Run a nested KVM instance: https://gist.github.com/arges/9d21c6da03a8c10d3980 [Fix] commit 4fa7734c62cdd8c07edd54fa5a5e91482273071a commit f3380ca5d7edb5e31932998ab2e29dfdce39c5ed -- I'm creating a vivid qemu guest on a trusty host with 3.13.0-48-generic kernel. When I start a guest inside that guest, I get the oops below on the host while the first guest hangs and must be (virsh) destroyed.
