[Xen-users] live migration problem and howto clear p2m table

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:
# xm migrate --live OpenSUSE10.1 xendom02
Error: /usr/lib/xen/bin/xc_save 10 17 4 0 0 1 failed

[Xen-users] Re: live migration problem and howto clear p2m table

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

[Xen-users] Re: live migration problem and howto clear p2m table

Problem seems to be alot worse. If I save the state on dom0_1 and "xm
restore" it on dom0_2 it gives the same suspicious looking fault:

Error: not a valid guest state file: pfn count out of range

Anyone ever encountered this?
