[Xen-devel] XEN-API problems

[Jacek Konieczny <jajcus@xxxxxxxxxx>]

Hello,

For my current project I need to automate domain creation and some basic
management. I thought XEN-API may be a better way than writing xm config
and calling xm to create and manage domains. 

Unfortunately the XEN-API documentation and examples I found seem a bit
outdated. By trial and error I managed to login to xend and create a VM
with a few VBDs (but I still don't quite understand how those VBD/VDI/SR
work)... however when trying to start the VM I get:

{'Status': 'Failure', 'ErrorDescription': ['INTERNAL_ERROR', "(11, 'Resource 
temporarily unavailable')"]}

In xend.log I get:

[2007-06-13 10:13:43 1905] ERROR (XendDomainInfo:1540) 
XendDomainInfo.initDomain: exception occurred
Traceback (most recent call last):
  File "/usr/lib/python2.5/site-packages/xen/xend/XendDomainInfo.py", line 
1517, in _initDomain
  File "/usr/lib/python2.5/site-packages/xen/xend/image.py", line 112, in 
createImage
  File "/usr/lib/python2.5/site-packages/xen/xend/image.py", line 131, in 
createDomain
  File "/usr/lib/python2.5/site-packages/xen/xend/image.py", line 517, in 
buildDomain
  File "/usr/lib/python2.5/site-packages/xen/xend/image.py", line 215, in 
buildDomain
Error: (11, 'Resource temporarily unavailable')
[2007-06-13 10:13:43 1905] ERROR (XendDomainInfo:416) VM start failed

There is nothing interesting in the "xm dmesg" output, despite "loglvl=all
guest_loglvl=all" xen boot options.

How can I find out what went wrong? Is the XEN-API usable at all? Is there any 
up-to-date
XEN-API documentation and/or examples available?

Greets,
        Jacek
