QEMU emulator version 0.15.0 (qemu-kvm-devel), Copyright (c) 2003-2008 Fabrice Bellard Find below the resulting command-line used to run a typical FreeBSD KVM from our Proxmox interface: /usr/bin/kvm -monitor unix:/var/run/qemu-server/141.mon,server,nowait -vnc unix:/var/run/qemu-server/141.vnc,password -pidfile /var/run/qemu-server/141.pid -daemonize -usbdevice tablet -name yournamehere -smp sockets=2,cores=2 -nodefaults -boot menu=on -vga cirrus -tdf -k fr -drive file=/var/lib/vz/images/141/vm-141-disk-1.qcow2,if=ide,index=0 -m 512 -netdev type=tap,id=vlan18d0,ifname=tap141i18d0,script=/var/lib/qemu-server/bridge-vlan -device e1000,romfile=,mac=9E:6C:42:78:98:E2,netdev=vlan18d0 -netdev type=tap,id=vlan730d0,ifname=tap141i730d0,script=/var/lib/qemu-server/bridge-vlan -device e1000,romfile=,mac=E6:BA:DA:56:C9:66,netdev=vlan730d0 -netdev type=tap,id=vlan731d0,ifname=tap141i731d0,script=/var/lib/qemu-server/bridge-vlan -device e1000,romfile=,mac=8E:B5:8F:30:F2:C1,netdev=vlan731d0 -id 141 -cpuunits 1000 Also find below the contents of the config file for the guest: -> cat /etc/qemu-server/141.conf name: [snip] bootdisk: virtio0 ostype: other memory: 512 onboot: 1 sockets: 2 ide0: local:141/vm-141-disk-1.qcow2 vlan18: e1000=9E:6C:42:78:98:E2 cores: 2 vlan730: e1000=E6:BA:DA:56:C9:66 vlan731: e1000=8E:B5:8F:30:F2:C1 Do not pay attention to "bootdisk: virtio0", we use "ide0" for other FreeBSD KVMs just as well. I'm beginning to think your VM might be crashing while/because it's actually probing for other devices. What's the full list of devices you have attached to your VM ? Do we have any boot stages expert on the list ?
