RE: [Xen-devel] xen 4.2 unstable; HVM; 2.6.39.3; HD/Network card error

["Walter Robert Ditzler" <ditwal001@xxxxxxxxx>]

hi stefano,
hi konrad,

thanks for replying :-) i followed your suggestions and changed the guest
config file. I have now the following test szenario:

server01 > should be a debian squeeze 6.0.1a amd64 netinst installation
server02 > is a successfully installed windows 7 x64 installation

bellow I paste the both config files. as you can see from the screen shots:

server01 installation
*********************
sh11: server01_debian-installer-1.JPG
sh12: server01_debian-installer-2.JPG
sh13: server01_debian-installer-3.JPG

the debian installation has some difficulties to find a harddisk. strange
is, that the networkcard was found straight away and I became a dhcp lease
from my infrastructure.

server02 installation
*********************
sh21: server02_xen_win7.JPG

the windows has been successfully installed onto my xen guest, but!!!!!


Q U E S T I O N S
*****************
- why do I see my server HP DL320G5 network card and disk controller?
- I thought, HVM means fully virtualized?! I expected to see something like
qemu/xen harddrive and qemu/xen network card!?
- Is here my xen really doing HVM
- how can I do HVM, I need my guests to be transferred to any different hw
boxes without need to deal with guest disk and network card drivers?




many thanks, walter

Considering that this is an hvm guest and that you only have one disk, it
should be hda rather than xvda.
Also it is probably not a good idea to disable acpi.

this is an hvm guest so extra is not going to do much, you need to pass
these parameters directly to the guest kernel from grub if you want them.
