Description Giulio Fidente 2014-10-14 12:56:28 UTC

Description of problem:
nested libvirt VMs based on rhel-guest-image 20140909.0 hang on boot with:

> ..TIMER: vector=0x30 apic1=0 pin1=2 apic2=-1 pin2=-1
> ..MP-BIOS bug: 8254 timer not connected to IO-APIC
> ...trying to set up timer (IRQ0) through the 8259A ...
> ..... (found apic 0 pin 2) ...
> ....... failed.
> ...trying to set up timer as Virtual Wire IRQ...


Version-Release number of selected component (if applicable):
qemu-common-2.0.0-1.el7.1.x86_64
qemu-kvm-common-1.5.3-60.el7_0.7.x86_64
qemu-system-x86-2.0.0-1.el7.1.x86_64


How reproducible:
launch a guest based on rhel-guest-image within a rhel7 vm hosted on a baremetal rhel7 system


Additional info:
guest boots successfully if no_timer_check is added as kernel paramter

it also seems there have been issues like this on centos5 with recent qemu, see https://lists.gnu.org/archive/html/qemu-devel/2014-02/msg03744.html
