But then, for no reason I can determine, they just go 100% busy and stop responding. My basic setup is: Ubuntu 8.10 server running on both host and guests. kvm version is the one from the Ubuntu distribution (kvm-72) Kernel is Ubuntu 8.10 kernel (2.6.27-7-server) The two VMs are both run like: kvm -daemonize \ -hda Imgs/ndev_root.img \ -m 1024 -cdrom ISOs/ubuntu-8.10-server-amd64.iso \ -vnc :1 -net nic,macaddr=DE:AD:BE:EF:04:04,model=e1000 \ -net tap,ifname=tap1,script=/home/chris/kvm/qemu-ifup.sh (With different disk imgs, vnc addresses and macaddrs) The disk images are raw format: qemu-img create -f raw 80G Imgs/ndev_root.img I've tried running with these options, and in different combos: -no-kvm-pit -no-kvm-irqchip -no-acpi They don't seem to help much. If anything, -no-kvm-irqchip seems to cause more troubles. I tried running with -no-kvm and it won't boot at all. I also built my own 2.6.27.4 kernel, from kernel.org, and built my own version of kvm-78, but saw the same behavior. Anyone have any advice how I can resolve these hangs? When the setup works, it's a beautiful setup and I love kvm. But with the 100% busy hangs I can't really continue with it. Thanks! Chris
