[Qemu-discuss] Installing QEMU from source causing error

[Probir Roy]

Hi,

I am trying to run Qemu-4.0 installed from source code.

When I run virt-manager to create a VM, I get the following error:

```
Unable to complete install: 'internal error: process exited while
connecting to monitor: 2019-07-19T17:06:35.954242Z qemu-system-x86_64:
-enable-kvm: unsupported machine type
Use -machine help to list supported machines'

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/asyncjob.py", line 89, in
cb_wrapper
    callback(asyncjob, *args, **kwargs)
  File "/usr/share/virt-manager/virtManager/create.py", line 2553, in

```

I configured the Qemu with following command:
```
./../configure --prefix=/usr --enable-spice --target-list=x86_64-softmmu
--enable-kvm --enable-debug --enable-libssh2
```

Is it that I missed enabling any configuration while installing Qemu? What
is the expected QEMU configuration to run with libvirt?
