I'm not sure if this bug is located in userspace or in the kernel. Could you let me know where to file it?
Bug: Attempting to boot a 32 bit Debian guest with a Xenomai kernel inside KVM causes it to hang and spin (using 1 full CPU core) after loading the initrd, as determined by serial console output. The only error message is "KVM internal error. Suberror: 1"/"emulation failure". Booting a regular Debian kernel succeeds, as does running the Xenomai kernel with software emulation (-no-kvm). Info: CPU: Intel Core i7-2670QM Emulator: qemu-kvm 0.14.1 Host kernel: 3.0.0-15 (Ubuntu build), x86_64 Guest OS: Debian Squeeze, kernel.org 2.6.37 kernel with Xenomai 2.6.0 (config attached) Qemu command: kvm -M pc-0.14 -enable-kvm -m 1024 -drive file=/var/lib/libvirt/images/eve.img,if=none,id=drive-ide0-0-0,format=raw -device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0 -netdev tap,fd=21,id=hostnet0 -device e1000,netdev=hostnet0,id=net0,mac=52:54:00:b5:f4:00,bus=pci.0,addr=0x3 -chardev stdio,id=charserial0 -device isa-serial,chardev=charserial0,id=serial0 -usb -device usb-tablet,id=input0 -vga cirrus Effects of flags: Adding one or both of --no-kvm-irqchip or --no-kvm-pit has no apparent effect. Adding --no-kvm appears to correct the problem. Trace will be attached to the final bug submission. Thanks, --Doug Brunner -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
