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
