Default 32bit HVM within CentOS5 x86_64+xen3?

Hi *!

I have to install a xen virtualization host that will start with 4GB RAM
and will maybe grow to 8GB in the future. And there has to be a 32bit
winXP domU. Is CentOS5(.1) x86_64 able to run 32bit HVMs or do i have to
stick with i386/PAE?

/nils.

Hi,

I'm using it with a Linux/Linux setup, without CPU VT. I had migrated
a CentOS4.5-i386 to a Xen DomU and switch to a Xen-x86_64 kernel (only the kernel).

But, you need windows, then you need VT on your CPU. With VT you can do
both windows and 32bit on a 64bit host.


Antonio.

So paravirtualisation of a 32bit domU with a 64bit dom0 works. But this
is not my use case.

I have. That's what i meant with "HVM"

Sure? OK, i'll give it a try.

Thanks, /nils.

Well, my servers didn't had VT (yet), then I didn't try it (yet), but
take a look on the manual section 1.2:
