[Qemu-devel] how to modify or add machines type ?

[Paul Schlacter]

I made the default config build the qemu-kvm , But I used virsh xml
corresponding machine-type inconsistent, resulting in an error.

error:
2017-09-06T12:16:36.036200Z qemu-kvm: -machine
pc-i440fx-rhel7.0.0,accel=kvm,usb=off: unsupported machine type
Use -machine help to list supported machines


Is there any way to modify the machines in qemu-kvm?
