I found a solution to the problem in Jaunty. To use SMP efficiently with Windows you need the ACPI Multiprocessor HAL profile. It seems you can only get it during the install if Windows detects that your HW fits that profile. The only solution I've found so far is to reinstall with ACPI enabled and make sure during install that the Multiprocessor HAL is selected.
The problem, in my case, is that virt-install did not enable ACPI even though I had asked it to do so. -- KVM eats 100% CPU, Host Hardy64, Guest XP with more than 1 VCPU https://bugs.launchpad.net/bugs/228442 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
