Using Ubuntu Lucid: kernel 2.6.32-21-server qemu-kvm-0.12.3 Also on Fedora 12: kernel 2.6.32.12-115.fc12.x86_64 qemu-0.11.0-13.fc12.x86_64 qemu-system-x86-0.11.0-13.fc12.x86_64 I've tried qcow2 and raw, with/without network device, cirrus/std/vmware vga... suggestions welcomed. -- Windows 2008 datacenter- 64 bit , installation fails with qemu-system-x86_64 0.11.50 https://bugs.launchpad.net/bugs/485239 You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU.
