On my AMD EPYC 7401P 24-Core Processor bare metal I get the following failures: FAIL vmware_backdoors (11 tests, 8 unexpected failures) (Why can't we just check /sys/module/kvm/parameters/enable_vmware_backdoor btw???) FAIL svm (15 tests, 1 unexpected failures) There is a patch for that: https://lore.kernel.org/kvm/d3eeb3b5-13d7-34d2-4ce0-fdd534f2bcc3@xxxxxxxxxx/T/#t Inside a VM on this host I see the following: FAIL apic-split (timeout; duration=90s) FAIL apic (timeout; duration=30) (I manually inreased the timeout but it didn't help - this is worrisome, most likely this is a hang) FAIL vmware_backdoors (11 tests, 8 unexpected failures) - same as on bare metal FAIL port80 (timeout; duration=90s) - hang again? FAIL svm (timeout; duration=90s) - most likely a hang but this is 3-level nesting so oh well.. FAIL kvmclock_test - bad but maybe something is wrong with TSC on the host? Need to investigate ... FAIL hyperv_clock - this is expected as it doesn't work when the clocksource is not TSC (e.g. kvm-clock) Are you seeing different failures? -- Vitaly
