kvm-50 working with smp
hi,
it seems the latest kvm-50 working with smp both with 32 and 64 bit centos-5 are now running (ie not crash), what's more it's even working if i trun back (ie on) acpi. but it seems much more slower with 2 guests 4 vcpu then kvm-36 with 2 guests single cpu. is so much slower then it can be recognized even just http response or anything else:-( another problem the windows xp guest eat 100% all the time.

Without FlexPriority (or tpr patching) Windows SMP is very slow. It shouldn't take 100% cpu though. If this is immediately after boot, wait a couple of minutes to let Windows load all its services.

but not just the windows are slow even all linux centos-5 32 and 64 bit version are _very_ slow much more slower than kvm-46 even the user experience is a few times slower the with kvm-46 with single cpu!

That shouldn't happen. Which kvm version introduced the problem (anything between -46 and -50)? Did you change anything other than kvm?

we don't change anything else (except try to use smp in guest and update to 50). i don't know which version. i know kvm-46 with single cpu was working in a reasonable speed while kvm-50 is about 10 times (!) slower with 4 vcpu.
