Package: qemu-kvm Version: 1.1.0+dfsg-3 Severity: grave Justification: causes non-serious data loss
Dear Maintainer, I currently run 3 VMs using libvirt/qemu-kvm. Two of them are mostly idle and stable, but the third one locks up within 1 or 2 days. This third VM uses an emulated ES1370 sound card (host has an ASUS Xonar DX sound card), to stream host audio input to an icecast server using darkice. The hanging kvm process uses 100% CPU, there's no serial console anymore, no access to VNC anymore. No output on netconsole either. Unfortunately, I cannot even get a useful gdb backtrace: # gdb GNU gdb (GDB) 7.4.1-debian Copyright (C) 2012 Free Software Foundation, Inc.
