Hello Does anyone have some advises regarding running a 16-bit executable in a virtualized 32-bit OS under KVM ? Would it be better to run a 32-bit linux kernel with PAE or a 64-bit kernel on the host ?
It doesn't matter. 64-bit is slightly preferable.
I imagine that KVM has to emulate all 16-bit instruction of a VM if running under a 64-bit host kernel. If using a 32-bit kernel, KVM could be able to use the vm86 mode for 16-bit instructions.
No, in both cases kvm uses whatever mode the guest asks for.
I know that PAE should be obsolete. But in my special case, I would use a host with 16 GB of RAM running different 32-bit VMs executing 16-bit binaries.
With 16GB of RAM 64-bit is the way to go. -- error compiling committee.c: too many arguments to function -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
