You really want to check what the OS is running, not what the CPU is,
because you can put a 32-bit OS on a 64-bit CPU. Since VMware only
copes with x86 platforms you can use
STREQ(utsname.machine, "x86_64") ? 64 : 32
As far as I know, it is possible to run 64-bit guests on a 32-bit host OS if
there is a 64-bit CPU with vmx/svm so I think we don't care what the OS is in
that case, don't we ?

Yes.
Ok, I thought the connectGetType() API was there to give more information
than the name field if relevant because virConnectGetType() returns
driver->name when the type function isn't available.
