Hello,

I'm trying to setup Kemari ontop of Xen ( http://www.osrg.net/kemari/ )

I'm not clear on some of the documentation and wondered if anyone on this list has got it to work.

I have 2 debain machines as my Dom0s, and have a HVM DomU VM which is running debain etch.

I'm able to live migrate between the 2 machines without a problem.

In the documentation it states that PV drivers are required in the guest domain.

What's not clear to me is, can I use any 3.3-testing PV drivers or are the ones in the patched kemari xen

tree required ? I've setup the ones in the tree, but I don't believe they are working properly.

dmesg in the guest vm shows -->

register_blkdev: cannot get major 3 for ide

vbd vbd-768: 19 xlvbd_add at /local/domain/0/backend/vbd/13/768

register_blkdev: cannot get major 22 for ide

vbd vbd-5632: 19 xlvbd_add at /local/domain/0/backend/vbd/13/5632

.....

xen_mem: Initialising balloon driver.

netfront: Initialising virtual ethernet driver.

Any idea how to fix the issue on "get major # for ide" ?

Does anyone know how to determine if the nic drivers are indeed in use on a HVM domu ?

Thanks,

Ian McCloy
