dell 755 e6550 virtualbox guest with 64bit doesnt work

[schtebo]

hello community,

i have a problem with my guest windows server 2008 64bit

my host: debian lenny 64bit
virtualbox: virtualbox 3.0.2

sources.list:
deb http://download.virtualbox.org/virtualbox/debian lenny non-free
#apt-get install virtualbox-3.0

every time i try to install windows server 2008 64bit it says that the hardware is not supported
i checked bios settings 3times an vt and other virtualization tools in bios are turned on and the cpu supports 64bit!

does someone have the same problem?

every time i try to install windows server 2008 64bit it says that the hardware is not supported

who did say that... windows?

try a 64bit linux guest to verify that your hardware works

[schtebo]

Code: Select all

this kernel requires an x86-64 CPU, but only detected an i686 CPU.
Unable to boot - please use a kernel appropriate for your CPU

so something is wrong, but what?
i used an amd64bit kernel cd for installing debian lenny so only the packages of virtualbox could by wrong...

[fixedwheel]

the debian packages from virtualbox.org are ok

thats what i have:

my host: debian lenny 64bit
virtualbox: virtualbox 3.0.2

sources.list:
deb http://download.virtualbox.org/virtualbox/debian lenny non-free

... but running on HP hardware

well i hope this works also with my dell machine

now i test this by installing windows xp 64bit and then virtualbox with windows server 2008 64bit


i report if this works/doesnt work

i found a solution: http://www.shnake.com/blog/?p=419

but i have to do this 7 times after a bios update to the latest version

8 hours for this stupid bug *arrrrrr*
