Looks like it will take about 40 seconds to run on Azure Standard-D48-v3, bump the timeout threshold to 60 or 90 should be able to solve this bug.

can start a KVM on it. Test apic will timeout on it. Steps: 1. git clone --depth=1 https://git.kernel.org/pub/scm/virt/kvm/kvm-unit-tests.git 2. cd kvm-unit-tests; ./configure; make 3.
