Hi,

I have a machine running several domU's. It has an LV that is currently mounted on dom0, that I would like to access from one of the domU's. If I umount the LV and remove it from the fstab on the dom0, is there a way I can mount it in one of the domU's?

to do it live, the keywords you want are

xm block-attach

but hotplug doesn't always work. in that case you will need to put it in the xm config file as a phy:/ device and restart the DomU.

YES!! That was the pointer I needed!! Thank You. I had actually figured out how to do most of this in virt-manager but I did not fully understand what I needed until I read the block-attach section of the xm man page.
