I've found out that the p2m table is held in the kernel so that it can be cleared by simply rebooting dom0.

But the live migration issue remains.

The receiving dom0 still spits out error messages after changing the /dev/hda1 to /dev/sdb1

Hi,

How can I clear the p2m table from xen? I have an "unexplained entry" which I'd like to remove, read on to see what caused it or if you can help with live migration.

I've set up iSCSI target on a seperate box and share a disk between my 2 Xen-dom0's as "/dev/sdb".

The domU works with storage settings:
disk = [ 'phy:/dev/sdb1,hda1,w' ]
root = "/dev/hda1 ro"
(/etc/xen/suse.conf on both dom0's)

When performing a live migration I get the following problem:

I saw that the migration was failing so I shut down xend on dom0_1 and restarted it ([2006-05-30 10:51:57 xend] INFO (SrvDaemon:185) Xend stopped due to signal 15.).

Why it was failing is a riddle to me, it complains about /dev/hda1 not found, but the root=/dev/hda1 setting means it's inside a domU right ? Maybe when sharing disks over iscsi I should use the following syntax to avoid trouble?
disk = [ 'phy:/dev/sdb1,hdb1,w' ]
root = "/dev/sdb1 ro"

I'd like to try, but it appears I destroyed something with my restarting of xend. As now when I try migration:
