the error does not seem related to guest type, rather to device addresses? (In reply to comment #1) > the error does not seem related to guest type, rather to device addresses? I assumed that it has to do with guest since, I tested thae same thing for Windows 7 guest and for RHEL 6.3 guest and it worked just fine. There was a decision not to block any guest os for now, please look at - BZ828854#c14 The fix for BZ 828854 will remove any os related limits |
