the comment #22 works perfectly with my xp VMs - I also set only one vcpu and acpi+apic enabled on these VMs -- 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 Server Team, which is subscribed to kvm in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Windows XP does not allow changing from non-acpi to acpi hal: http://support.microsoft.com/kb/315278 and http://support.microsoft.com/kb/309283 But as a workaround you can go to Device Manager - Computer - MPS Multiprocessor and update the driver to Standard PC. This will give 1 idle processor to Windows instead of full workload cpus. -- 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 Server Team, which is subscribed to kvm in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Downgrading to confirmed/low based on that : this bug is fixed in virt- manager, but KVM could still refuse to try to do multiple VCPU when ACPI is disabled (rather than trying and failing at it). ** Changed in: kvm (Ubuntu) Importance: High = Low ** Changed in: kvm (Ubuntu) Status: Incomplete = Confirmed -- 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 Server Team, which is subscribed to kvm in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

virt-manager (actually virtinst) correctly enables ACPI now for WinXP on kvm.

I believe this is a known issue for Windows XP VM's. Do you have hardware virtualization? Many older CPU's do not have support for virtualization and this is known to cause Windows XP x32 VM's to run the processing power all the way up. Vista and XP x64 have support for 'lazy IRQL' which allows them to bypass this need. -- 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 Server Team, which is subscribed to kvm in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Marking this bug against virt-manager. Well, that's just silly: If you disable ACPI, you can't do SMP. Then kvm should refuse to try, surely? -- 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 Server Team, which is subscribed to kvm in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
