[Back to blogging after busy season of ….]
Any way, its a very common query on qemu/kvm and most of the people dont know .. It is really useful to know which options are available with some of the devices and qemu-kvm binary…
Here is an example on the same: You have to replace your qemu binary path accordingly
First of all if you want to list the devices available for the qemu binary, please list it using :
[terminal]
[root@node ~]# /usr/bin/qemu-kvm -device ?
name “pci-bridge”, bus PCI
name “virtio-scsi-pci”, bus PCI, alias “virtio-scsi”
name “virtio-balloon-pci”, bus PCI
name “virtio-serial-pci”, bus PCI, alias “virtio-serial”
name “virtio-net-pci”, bus PCI
name “virtio-blk-pci”, bus PCI, alias “virtio-blk”
name “i82562”, bus PCI
*****
[/terminal]
If you want to list specific options of a particular device, view it by invoking in similar way as below.. Here I used “virtio-net-pci” as an example..
[terminal]
[root@node ~]# /usr/bin/qemu-kvm -device virtio-net-pci,?
virtio-net-pci.ioeventfd=on/off
virtio-net-pci.__com_redhat_macvtap_compat=on/off
virtio-net-pci.x-__com_redhat_rhel620_compat=on/off
virtio-net-pci.vectors=uint32
virtio-net-pci.indirect_desc=on/off
virtio-net-pci.event_idx=on/off
virtio-net-pci.csum=on/off
virtio-net-pci.guest_csum=on/off
virtio-net-pci.gso=on/off
virtio-net-pci.guest_tso4=on/off
virtio-net-pci.guest_tso6=on/off
virtio-net-pci.guest_ecn=on/off
virtio-net-pci.guest_ufo=on/off
virtio-net-pci.host_tso4=on/off
virtio-net-pci.host_tso6=on/off
virtio-net-pci.host_ecn=on/off
virtio-net-pci.host_ufo=on/off
virtio-net-pci.mrg_rxbuf=on/off
virtio-net-pci.status=on/off
virtio-net-pci.ctrl_vq=on/off
virtio-net-pci.ctrl_rx=on/off
virtio-net-pci.ctrl_vlan=on/off
virtio-net-pci.ctrl_rx_extra=on/off
virtio-net-pci.ctrl_guest_offloads=on/off
virtio-net-pci.ctrl_mac_addr=on/off
virtio-net-pci.mac=macaddr
virtio-net-pci.vlan=vlan
virtio-net-pci.netdev=netdev
virtio-net-pci.bootindex=int32
virtio-net-pci.x-txtimer=uint32
virtio-net-pci.x-txburst=int32
virtio-net-pci.tx=string
virtio-net-pci.addr=pci-devfn
virtio-net-pci.romfile=string
virtio-net-pci.rombar=uint32
virtio-net-pci.multifunction=on/off
[/terminal]
The same way you can list available CPUs and Machine types
-M ?
-cpu ?
For ex:
[terminal]
[root@node ~]# /usr/bin/qemu-kvm -cpu ?
x86 Opteron_G5 AMD Opteron 63xx class CPU
x86 Opteron_G4 AMD Opteron 62xx class CPU
x86 Opteron_G3 AMD Opteron 23xx (Gen 3 Class Opteron)
x86 Opteron_G2 AMD Opteron 22xx (Gen 2 Class Opt
..
[/terminal]
