hi, I'm using kvm-48 which has apic kernel support know.
But I found when working on uniprocessor, the ioapic of kvm is not used.
Kvm only use pic when it works on uniprocessor?

This patch complements "Partial IDE DVD emulation" (revision 1.66 for ide.c
in qemu's cvs) that is generating the following timeouts for OpenSolaris
guests when trying to access the ATAPI cdrom (ex: during installation):
WARNING: /[EMAIL PROTECTED],0/[EMAIL PROTECTED],1/[EMAIL PROTECTED] (ata1);
The following patch series implements fixes to the IDE/ATAPI emulation
in qemu which affects access to the CD-ROM device preventing installation
of OpenSolaris guests because of an incorrect implementation of the MMC6
GET_CONFIGURATION command when it was extended to also support a DVD-ROM
profile.
