Subject: [Xen-users] 32bit DomuU on 64-bit Xen
Hi,
from what I could find digging around, it is ok to run a 32-bit DomU
with a 64bit Xen/Dom0 as long as you use linux32 to avoid the package
utilities from trying to install 64 bit packages in the DomUs.
Ehm, no you CAN NOT run 32-bit DomU on a 64-bit Xen/Dom0, because all
kernel modes must be the same (32-bit no PAE, 32-bit PAE or 64-bit).
What I thought was possible is to start the 32-bit DomU with a 64-bit
kernel and use a custom initrd to call linux32 before /sbin/init -> the
whole DomU could still be 32-bit, but the kernel would be 64-bit. I'm
wondering if there could be problems with some userland system utilities
like iptables though.
Can't this work?
Lionel
