I was booting the same Xenial based HVM guest on the same host (but this time running Bionic / Xen 4.9). This combination does not crash the domain when opening HPET. Though the check and code that would do it is still there. I also found a bug report against xenserver which I believe is based on the same Xen version as we have in Xenial (4.6.5): https://bugs.xenserver.org/browse/XSO-809?focusedCommentId=16484&page=com.atlassian.jira.plugin.system.issuetabpanels %3Acomment-tabpanel
This and the code say that the crash is done because HPET is set to use an unsupported interrupt method (edge/level). Since the Linux guest is the same in both cases, and also the test + crash code, either the hypervisor or maybe the seabios seem to use a different default. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1741409 Title: stress smoke test hang with dev test on AWS Xenial kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-aws/+bug/1741409/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
