[Xen-users] RHEL4 as 64-bit HVM guest -- not starting in 64 bit mode
I''m trying to install RHEL 4 on an HVM (Core 2 Duo). However, when
the RHEL installer tries to start the kernel, it complains that the
CPU doesn''t support extended mode, and that I should use a 32-bit
installer.
However:
hrm@willow:~$ sudo xm info | grep xen_caps
xen_caps : xen-3.0-x86_64 hvm-3.0-x86_32 hvm-3.0-x86_32p
hvm-3.0-x86_64
Is there some magic I need in the config file for the domain to
tell it that it''s a 64-bit guest?
Hugo.

I''d also, if you''re not doing so already, use the latest 3.0.3, as previous versions are known to not work right for 64-bit at least sometimes. -- Mats> > Hugo. > > -- > === Hugo Mills: hugo@... carfax.org.uk | darksatanic.net | > lug.org.uk ==> PGP key: 1C335860 from wwwkeys.eu.pgp.net or > http://www.carfax.org.uk > --- Nothing wrong with being written in Perl...

It''s related to the device model configuration. I had previously tried to map one LV to /dev/hda1 and another LV to /dev/hda2. If I simply map each to a different full hard disk image, everything works. It seems odd that I should get an error about not being able to enter 64-bit mode as a result of a mis-configured hard disk image, but that''s the only conclusion I can draw. Thanks for your help, Mats.
