[Xen-devel] XCP (bug?): another frontend device is already connected to this domain

[George Shuklin <amarao@xxxxxxxxxxx>]

Good day. 

After few month of test usage suddenly got strange behavior:
xe vm-install template=... new-name-label=...
xe vif-create ...
xe vm-param-set uuid=... other-config:install-repository=....
xe vm-start uuid=...

Got following error message:

The server failed to handle your request, due to an internal error.  The
given message may give details useful for debugging the problem.
message: another frontend device is already connected to this domain
(frontend (domid=0 | kind=vbd | devid=51712); backend (domid=0 |
kind=tap | devid=51712))

If I recreate VBD, it seems fine but say usual error about 'non
bootable' (as if I run installation once and stops it).

Main concern - first error message? What it is? And how can I debug i

xensource.log is clear:
