Re: [Xen-devel] trying to get a domU to manage lvm pvs (SUCCESS)

Wonderful. Thank you thank you thank you. :)

I tried the switch to sda and that does indeed work fine (I'll try the fix for hda soon). More importantly, it works perfectly with the more complex scenario I was attempting which was to export 3 raid5 md devices which are the actual pvs for the vg that I want managed by the domU.

My disk setup now looks like this:
disk = [ 'phy:xen_vg/fileserver,hda1,w',

I have my dom0 entirely on md0 (raid1), with its swap on md1(raid1). I have a number of xenU's, each occupying a lv on a raid5 backed vg (xen_vg above), with each of them having swap space allocated on a another raid1 backed vg (xen_swap_vg above), and then 3 raid fives that collectively make up the vg that my "fileserver" xenU manages.

Initial testing says that it works flawlessly. Woo hoo.
