Re: [Xen-users] Xen 3.1.0 on Fedora 7- libvir: Xen Daemon error :GET operation failed

[Dylan Martin <dmartin@xxxxxxxxxxxx>]

I recently upgraded also from FC6 to F7.  The config file parser is a
little more picky than it used to be, so try commenting out bunches of
lines in your xm config file and see if that changes anything.

I haven't used virt-install.  I ususally write my xm configs by hand,
run them  with xm and install the OS with the normal OS installer.

I've been trying to keep notes of my work.  You can see them here.
They're probably not very helpful, but you never know:
