Hi,
Michel, you're right ; I got this error :
virDomainAttachDeviceFlags( ) error operation forbidden: read only access prevents virDomainAttachDeviceFlags
Either via "virsh attach-device" or via "virDomainAttachDeviceFlags()" , I encounter an error due to the fact that an authorized user is required.
Script-wise the error is the following :
Please enter your authentication name:
> Please enter your password:
> error: failed to connect to the hypervisor
> error: no valid connection
> error: authentication failed: Failed to step SASL negotiation: -1
> (SASL(-1): generic failure: All-whitespace username.)
I have now to add a user , following this ovirt people recommendation :
When you attach a compute node to oVirt, it sets up auth with libvirt to prevent admins from connecting to libvirt.
If you want to override that you need to create yourself a SASL user + password using the saslpasswd2 command
Thx for help.
Regards,
J.P.

This looks like the client has not even gotten into RPC call. This means that you are passing a wrong argument somewhere. You can:
1) check here what arguments are being checked for:
http://libvirt.org/git/?p=libvirt.git;a=blob;f=src/libvirt-domain.c;h=b91388e77e00bf30674f3e25fbdfd38b8626c351;hb=HEAD#l8301
2) Use virGetLastError() to check the actual error.
