Bug Detailed Description:
kvm-unit-test xapic fails on the linux 6.1 release kernel. 

FAIL: Want 2 IPI(s) using physical mode, dest = 5d, got 1 IPI(s)
qemu-system-x86_64: terminating on signal 15 from pid 208676 (timeout)
FAIL xapic (timeout; duration=60)


Reproducing Steps:

git clone https://gitlab.com/kvm-unit-tests/kvm-unit-tests.git
cd kvm-unit-tests
./configure
make standalone
cd tests
./xapic

Actual Result:

PASS: APIC physical broadcast address
PASS: APIC physical broadcast shorthand
PASS: IPI to single target using logical flat mode
PASS: IPI to single target using logical cluster mode
FAIL: Want 2 IPI(s) using logical flat mode, dest = 3, got 1 IPI(s)
FAIL: IPI to multiple targets using logical flat mode
FAIL: Want 2 IPI(s) using logical cluster mode, dest = 3, got 1 IPI(s)
FAIL: IPI to multiple targets using logical cluster mode

KVM-unit-tests got ahead of KVM proper.  The test will fail until the KVM
fixes[*] land.  That should happen sooner than later.
