The host where the problem doesn't happen runs Ubuntu 16.04 with kernel 4.15.0-58-generic and qemu-kvm 1:2.5+dfsg-5ubuntu10.41
My work desktop is running on Ubuntu 18.04 with kernel 5.0.0-25-generic and qemu-kvm 1:2.11+dfsg-1ubuntu7.17 The Oracle Bare Metal host is running Ubuntu 18.04 (minimal install) with kernel 4.15.0-1025-oracle and qemu-kvm 1:2.11+dfsg-1ubuntu7.18 The RHEL4 guest runs kernel 2.6.9-67.ELsmp I tested two additional VMs, this time they are on Ubuntu 8.04 with kernel 2.6.24-32. One exhibits a similar issue, but the other one doesn't. VMs running more recent Ubuntu releases and even Windows 7 guests do not exhibit this problem. So it is likely because of the old kernel version being incompatible with the newer ACPI tables qemu provides. :( Unfortunately, I cannot migrate the apps running in these VMs to a more recent RHEL release. :( Is there a way to provide these guests with old kernel the older SDT's? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1845290 Title: ACPI issue with RHEL4 guest VM's To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1845290/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
