Introduce testDomainChgDevice for further development (just like what we
did for IOThread). And introduce testDomainDetachDeviceLiveAndConfig for
detaching devices.

My comment from the previous patch would be nicely usable here as we could easily just make use of it. Also I see no reason for splitting the next two patches from this one. [...]

So here you check for both live and config, saying both of them are supported, ...

But here it would fail with both since you are explicitly saying you want just one definition.

+ parse_flags |= VIR_DOMAIN_DEF_PARSE_SKIP_VALIDATE;

+ driver->caps, parse_flags)))
+ goto cleanup;
+ } else if (alias) {
+ dev = g_new0(virDomainDeviceDef, 1);

+ case VIR_DOMAIN_DEVICE_ACTION_DETACH:
+ if (testDomainDetachDeviceLiveAndConfig(def, dev) < 0)
And I kind of see now why you call the function "LiveAndConfig" since it can do both based on what DomainDef you call it with. This function could be very easily modified to do both live and config properly.
