Question How can i generate a virtual machine Linux X86_64 (64bits) in a Server 32 Bits?


I have a problem with Linux Red Hat 4 for 64 Bits, because i Have a Hardware 32 Bits (i need this version of red hat 4 for 64 bits)
I have a binaries of db in 64 bits, What software on virtual machines support this?
Note: I have install Linux Red Hat 4 32 bits, i need generate a virtual machine with Linux Red Hat 4 of 64 Bits.

Maybe with something like qemu, but it will run like shit. you are proposing that you emulate a 64 bit cpu with a 32bit cpu, this will have to be done in software and will be very ssssssssssssllllllllllllllllloooooooooooooooooooowwwwwwwwwwwww!!!!!!!!! if it is even possible. 64bit cpus have dedicated hardware to emulate 32bit ones because even this wold be slow in software. you will never get anything closely resembling a useable virtual machine this way.

Do you mean Red Hat 4 (holy freaking crap!) or RHEL 4? They're two totally different products.

Also, why do you NEED the 64-bit edition of any distro? It's been debated extensively, and the general consensus is that at this point in time, the only advantage in owning a 64-bit CPU with a 64-bit OS is for those doing number crunching.

AFAIK there is not 64-bit emulator. I dont think it is even possible. You are talking about computing a 64-bit integer on a 32-bit system. a 32-bit emulator is possible on a 64-bit system but not the other way.

well that just isn't true. otherwise there never would have been nintendo64 emulators for 32bit computers. it is possible it's just really slow. according to the qemu status page it does emulate x86_64 systems on a x86 system.

Thanks for the info. I guess it might be possible to split each allocation into 2 parts and process them then join them back together. IDK if that is how it is done but if it is that would explain why it is slow.
