Subject: [PATCH] KVM: selftests: memslot_perf_test: increase guest sync timeout
Date: Fri, 4 Oct 2024 18:01:53 -0400 [thread overview]
Message-ID: <20241004220153.287459-1-mlevitsk@redhat.com> (raw)
When memslot_perf_test is run nested, first iteration of test_memslot_rw_loop
testcase, sometimes takes more than 2 seconds due to build of shadow page tables.
Following iterations are fast.
To be on the safe side, bump the timeout to 10 seconds.
