/mnt/vm/disks/PRECISE.disk1.xm exist, domU hvm with raw
disks works
Is xen bug, kernel bug or my error?
Thanks for any reply

Hello,
I think that the raw parameter isn't needed and is the reason
for the device connecting error. Another way to install the
guest would be to use debootstrap. This definitly works.

Format seem necessary or give this error:

Hello,
do you also have tried to install the guest with debootstrap?

I tried with Wheezy PV and install working, after I retried with
Precise on new disk and working, seem was only filesystem problem
for ext4 bug or bad blocks.
Now the problem is another one: I tried to start PV domUs but did
not work.
On Wheezy domU I tried with pygrub, pv-grub and also with menu.lst
with minimal grub1 configuration.
See below output and logs.

Before xen build I had do this change for python tools working:
vi Config.mk
PYTHON_PREFIX_ARG =
Are there other check or modify I must do for have pygrub working on
xen 4.2?
Thanks for any reply
