Re: [Libguestfs] Man pages for virt-p2v-server?



Hisao, thank you for that Microsoft article pointer.  I finally had a
chance to look it over and the direction it takes makes lots of sense.
If we could come up with a way to install the virtio disk driver on the
physical Windows machine before the P2V, then the driver should load on
the migrated VM when it boots from its virtual virtio disk.  This could
be major step forward.  And it could work in lots of situations.  

By the way, where did everyone go the past several days?

- Greg

What kind of error happened when booting?
If it is Blue Screen of Death "Stop 0x0000007B error",
following information might help you.

http://support.microsoft.com/kb/314082

I did P2V successfully from my Laptop PC (Win XP) to KVM guest
using Clonezilla Live CD with the following step (I did not use
virt-p2v).

1. Before P2V, apply above registry modification to Win XP.
2. Boot Latptop PC with Clonezilla Live CD and backup it to samba file
server.
3. Create KVM guest and boot it with Clonezilla Live CD and restore from
samba file server.

But I have no experience about Windows 2003 Server's P2V.
