Thanks Ryan,
I applied the patch and restarted xend.
We're definitely much closer. The domain creation still bombed but for
other reasons. The value of ['func','0x1'] is being erroneously
reported as ['func','0x0'], which explains the following error:
"Failed to open & read /sys/bus/pci/devices/0000:00:0f.0/resource: No
such file or directory".
I'm glad that you caught that problem. I made a mistake in my regular
expression. Try the attached patch instead and let me know how it works.
Congratulations Ryan! Great job.
Good news is I've successfully rebooted two different domains, each with
an exported pci device.
Bad news is xendomains fails to autostart the domains.
Good news is the same regular expression error exists in
python/xen/xm/create.py in preprocess_pci on line #657.
Bad news is xendomains still fails.
I'll post what I find under a new thread.
Thanks again,
:m)
Ryan
