kvm 使用virtio 加速

 

 

kvm -hda ubuntu-server.img -cdrom NETKVM-20081229.iso -m 1024 -enable-kvm -net nic,model=virtio -net user

kvm -hda ubuntu-server.img -m 1024 -boot c -net nic,model-virtio -net user

kvm: -net nic,model-virtio: Invalid parameter 'model-virtio'

 

kvm -hda ubuntu-server.img -m 1024 -boot c -net nic,model=virtio -net user 这个不成功

 

 

root@ubuntu:/home/hypercube/kvm# kvm file=ubuntu-server.img,if=virtio,boot=on -m 1025

kvm: -m 1025: could not open disk image file=ubuntu-server.img,if=virtio,boot=on: No such file or directory

 

 

kvm -drive file=ubuntu-server.img,if=virtio,boot=on

qemu-kvm: boot=on|off is deprecated and will be ignored. Future versions will reject this parameter. Please update your scripts.

kvm -drive file=ubuntu-server.img,if=virtio -m 2048
