Re: [Xen-users] patch to fix xendomains non-fatal error (4.5-unstable)

[Mark Pryor <tlviewer@xxxxxxxxx>]

Wei,

Running `xl list -l 0` I can see with strace that libxl trys to open (when dom0 
guid is null)
/var/lib/xen/userdata-d.0.00000000-0000-0000-0000-000000000000.libxl-json

When looking over the source
xen-init-dom0.c

I could not see where the metadata for dom0 was read from or written to. It 
seems
that no file is ever written by this App. I can see that it is running in logs 
way before xendomains starts, in fact it runs concurrent with xenstored. It 
writes to log that
`dom0 is already setup`

If you redo the patch, include the changes to ./tools/configure.ac

The core idea is to invoke xen-init-dom0 before starting xendomains.

I will post a patch series to fix this properly.
