[Xen-users] Error: Internal Server Error when saving domain

Hi,

I''m a xen newbie and am having trouble saving a xen
domain.  When attempt to save the domain via, xm save
<domainName> <fileName>,  I receive the "Error:
Internal Server Error" on the cmdline. 

Upon looking in the logs I see a suspicous message
"exceptions.OSError: [Errno 2] No such file or
directory: ''/var/lib/xen/xend-db/migrate/''". Indeed
/var/lib/xen/xend-db/migrate does not exist on my
system. The only directories within the xend-db
directory are: domain, and vnet.  

I''m not sure what the problem is.  Can someone please
help?

Thanks,
Tom

I found the answer in this thread
http://lists.xensource.com/archives/html/xen-users/2005-06/msg00117.html

mkdir /var/lib/xen/xend-db/migrate
ln -s /usr/lib/libcurl.so.3  /usr/lib/libcurl.so.2
