Red Hat Bugzilla – Bug 218773
"acpi" and "apic" can't be changed by user with virt-manager
Last modified: 2010-10-22 03:19:14 EDT
+++ This bug was initially created as a clone of Bug #214361 +++
Description of problem:
In virt-manager, "acpi" and "apic" are always set as "1".
In some cases, it's necessary to set "acpi" and "apic" as 0, for example a
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Launch virt-manager and connect to the local xen instance.
2.Click "New" button and create a VM.
3.The items were set as follows.
start up memory: 512
maximum memory : 512
domain name : winsrv2k3
virtualization method : Fully virtualized
installation source : /dev/hda
disk type : file
disk image : /root/winsrv2k3.img
disk size : 4000
vcpus : 1
4.Refer the configuration file under "/etc/xen".
The value of "acpi" and "apic" are always set as "1" by virt-manager.
The value of "acpi" and "apic" can be changed by user with virt-manager.
The configuration file, "winsrv2k3", is attached with this report.

We don't plan to expose the 'acpi' and 'apic' settings directly through the
virt-manager UI, because no average user stands any hope of understanding what
they mean. Instead the plan is to build up a database mapping "OS type/version"
to "required set of acpi, pic settings". The wizard will then present a way to
select what OS type is being installed & automatically apply the optimial
acpi/pic settings to make it work.
This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux maintenance release. Product Management has requested
further review of this request by Red Hat Engineering, for potential
inclusion in a Red Hat Enterprise Linux Update release for currently deployed
products. This request is not yet committed for inclusion in an Update
fixed in virt-manager-0.4.0-1.el5 (in that we allow users to choose an
os-type/os-version pair, which will set acpi and apic appropriately).
An advisory has been issued which should help the problem
