--- Begin Message ---Package: src:linux Version: 3.16.7-ckt4-3 Severity: important Tags: upstream Dear Maintainer, We have observed some strange behavior while dist-upgrading some of our VMs from wheezy to jessie kernels. Under certain circumstances the combination of a jessie guest on a wheezy host might lead to VM crashes while one is using the qemu-kvm VNC port. Steps to reproduce: 1. Wheezy host with kernel 3.2.0-4-amd64 2. Wheezy-bpo or Jessie KVM guest with kernel linux-image-3.16.0-4-amd64 3. Connect with a VNC client to the guest's KVM-VNC port 4. cat /dev/urandom while on VNC 5. Wait from a few seconds to 2-3 minutes and then the OS inside the VM crashes. The KVM process is still running but the KVM socket is not responding. The guest OS is inaccessible and the vm (after a restart) shows no signs of having crashed. We have done testing with various Debian kernels as both host and guest and also testing with other distributions as guests. Our tests so far have shown that on a host running a wheezy-bpo/jessie kernel the crash does not appear to happen. We can reproduce the bug on Debian Jessie and Centos 7, but not on Ubuntu LTS or the latest GRML live cd. Here's a matrix of what works and what doesn't: HOST KERNEL | GUEST KERNEL | qemu-kvm version | Crash | Notes 3.2.63-2+deb7u1 | 3.2.65-1 | 1.1.2+dfsg-6+deb7u4 | no | wheezy on wheezy 3.2.63-2+deb7u1 | 3.16.7-ckt4-3 | 1.1.2+dfsg-6+deb7u4 | YES | jessie on wheezy 3.2.63-2+deb7u1 | 3.10.0-123.20.1.el7.x86_64 | 1.1.2+dfsg-6+deb7u4 | YES | centos7 on wheezy 3.2.63-2+deb7u2 | 3.2.65-1 | 2.0.0+dfsg-4~bpo70+1 | no | wheezy on wheezy with KVM from bpo 3.2.63-2+deb7u2 | 3.16.7-ckt4-3 | 2.0.0+dfsg-4~bpo70+1 | YES | jessie on wheezy with KVM from bpo 3.2.65-1 | 3.16.7-ckt4-3~bpo70+1 | 1.1.2+dfsg-6+deb7u6 | YES | wheezy-bpo on wheezy 3.16.7-ckt4-3~bpo70+1 | 3.16.7-ckt4-3~bpo70+1 | 1.1.2+dfsg-6+deb7u6 | no | wheezy-bpo on wheezy-bpo 3.2.63-2+deb7u2 | 2.6.32-504.8.1.el6.x86_64 | 2.0.0+dfsg-4~bpo70+1 | no | centos6 on wheezy 3.2.63-2+deb7u2 | 2.6.32-5 | 2.0.0+dfsg-4~bpo70+1 | no | squeeze on wheezy with KVM from bpo 3.16.7-ckt2-1 | 3.2.65-1+deb7u1 | 2.1+dfsg-11 | no | wheezy on jessie 3.2.63-2+deb7u2 | 3.13.0-39-generic | 2.0.0+dfsg-4~bpo70+1 | no | ubuntu 14.04 on wheezy with KVM from bpo 3.2.63-2+deb7u2 | 3.16.7-1+grml.1 | 2.0.0+dfsg-4~bpo70+1 | no | grml on wheezy with KVM from bpo 3.2.65-1 | 3.4-trunk-amd64 | 1.1.2+dfsg-6+deb7u6 | no | wheezy 3.4 trunk on wheezy 3.2.65-1 | 3.6-trunk-amd64 | 1.1.2+dfsg-6+deb7u6 | no | wheezy 3.6 trunk on wheezy 3.2.65-1 | 3.7-trunk-amd64 | 1.1.2+dfsg-6+deb7u6 | no | wheezy 3.7 trunk on wheezy 3.2.65-1 | 3.8-trunk-amd64 | 1.1.2+dfsg-6+deb7u6 | YES | wheezy 3.8 trunk on wheezy >From our tests the problem first appears when the guest uses kernel >3.8-trunk-amd64.
