--- Begin Message ---Package: qemu-system-x86 Version: 1.7.0+dfsg-9 Severity: grave Justification: renders package unusable Dear Maintainer, Since kernel 3.13 migrated into jessie, I cannot start KVM guests anymore. If I boot on the last jessie 3.12 kernel (3.12.9-1), I can start the guests with no problem. I hoped some newer kernel and qemu would fix it and waited both have a new version in jessie which is now the case; unfortunately the result is the same: after starting the guest with a command-line such as: kvm -net nic,model=virtio -net tap,script=no,downscript=no,ifname=tap0 -drive file=/var/local/kvm/taz-test.img,if=virtio -usbdevice tablet -k fr -vnc localhost:2 -daemonize -name taz-test The cpu goes 100% for a while and then the kernel is spouting messages on all terminals. This is what I get in syslog: Apr 22 10:56:39 ataz kernel: [ 9050.996004] INFO: rcu_sched self-detected stall on CPU { 1} (t=5250 jiffies g=194196 c=194195 q=1118) Apr 22 10:56:39 ataz kernel: [ 9050.996004] sending NMI to all CPUs: Apr 22 10:56:39 ataz kernel: [ 9050.996004] NMI backtrace for cpu 1 Apr 22 10:56:39 ataz kernel: [ 9050.996004] CPU: 1 PID: 19798 Comm: qemu-system-x86 Not tainted 3.13-1-686-pae #1 Debian 3.13.10-1 Apr 22 10:56:39 ataz kernel: [ 9050.996004] Hardware name: Dell Inc.

--- Begin Message ---It looks like with kernel 3.14 (and probably 3.13.x with x>0) this problem has been fixed in the kernel (and indeed it was a kernel bug). I'm closing this bugreport now, hoping it works for you with current kernel. If not, please either reopen the bugreport (indicating wich version doesn't work still), or file a new bugreport against the kernel. Thanks, /mjt
