Subject: [PATCH kvm-unit-tests] reduce number of iterations for apic test
Date: Sat, 31 Oct 2020 10:40:52 -0400 [thread overview]
Message-ID: <20201031144052.3982250-1-pbonzini@redhat.com> (raw)
The test generally fails quite quickly, 1 million iterations is
a lot and, on Azure cloud hyperv instance Standard_D48_v3, it will
take about 45 seconds to run this apic test.
It takes even longer (about 150 seconds) to run inside a KVM instance
VM.Standard2.1 on Oracle cloud.
