I'm seeing problems with this using a Debian Lenny guest, it gets glibc realloc errors in the init scripts/initramfs. Using -no-kvm or setting oos_shadow=0 works around the problem. I also confirmed it was introduced in commit 641fb03992b20aa640781a245f6b7136f0b845e4. It should be reproducible using an install from this media: http://cdimage.debian.org/cdimage/lenny_di_beta2/i386/iso-cd/debian-LennyBeta2-i386-businesscard.iso Host system is running 2.6.27 x86_64 on Intel Xeon E5450. After install, the guest fails to get to a login prompt w/o the above workarounds. Running the guest as: /usr/local/kvm/bin/qemu-system-x86_64 -L /usr/local/kvm/share/qemu -drive file=/dev/VM/Debian,if=ide,index=0 -m 512 -net nic -net user -vnc :1 Thanks, Alex -- Alex Williamson HP Open Source & Linux Org. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
