With this configuration when i boot from vdb i can install OS with grub and after it redefine XML without vdb without problem. Thanks a lot.

Ah, of coure. I overlooked that virDomainDetachDeviceFlags() is called
with VIR_DOMAIN_AFFECT_CONFIG, which means that live configuration is
not affected and if the disk you're trying to detach exists only in live
XML then the API fails. The same problem was found in
libvirt_domain_disk_add, libvirt_domain_nic_add and
libvirt_domain_nic_remove.

I've pushed the fixes to the master. Thanks for the report.
