I found the real problem. Read the bottom where I said "forget all that". Everything above that was things that I had tried.

I took the source and compiled it. I used build/x86_64-softmmu/qemu-system-x86_64 from the 1.0+dfsg-11 source package after it was compiled. I made NO changes to anything. I issued debian/rules build to compile and stripped the binary mentioned above. I could not reproduce this error with the one I compiled. I extracted the kvm binary from the 1.0+dfsg-11 amd64 package to a temporary location. It still gives me the same error. It may be possible that I have an older library or something is different on my system. One difference I found is that I'm using gcc 4.6.1-8. The kvm binary from the -dbg package contains GCC: (Debian 4.6.3-3) 4.6.3 GCC: (Debian 4.4.6-14) 4.4.6 Not sure which it was compiled with. I cleaned and recompiled it with gcc-4.4.6-6. Still not able to reproduce. I could not find the 1.0+dfsg-10 amd64 package (I did find the i386 package) to check with that version. One more test I did. I ran your exact command line (only changing the path to kvm) # /junk/kvm/qemu-kvm-1.0-11-debian/usr/bin/kvm -fsdev local,security_model=mapped,id=fsdev-fs0,path=/var -device virtio-9p-pci,id=fs0,fsdev=fsdev-fs0,mount_tag=kernel,bus=pci.0,addr=0x3 -M pc-0.14 -nodefaults -vga std (process:22949): GLib-CRITICAL **: g_thread_pool_new: assertion `g_thread_supported ()' failed worker thread initialization failed # You know what, forget all of the above. My libglib version is 2.28.6-1. I extracted the library from libglib2.0-0_2.32.3-1_amd64.deb and ran: LD_LIBRARY_PATH=/junk/kvm/glib/lib/x86_64-linux-gnu /junk/kvm/qemu-kvm-1.0-11-debian/usr/bin/kvm -fsdev local,security_model=mapped,id=fsdev-fs0,path=/var -device virtio-9p-pci,id=fs0,fsdev=fsdev-fs0,mount_tag=kernel,bus=pci.0,addr=0x3 -M pc-0.14 -nodefaults -vga std and it works fine. The fix for this bug might be to just depend on a newer version of libglib2.0-0. I upgraded this package on my system and qemu-kvm and everything is happy. -- Microsoft has beaten Volkswagen's world record.
