Verified for Focal according to test case from description. A standard multipass VM with 8 vCPUs configured was able to capture a kernel dump without errors.
Additionally, since the 5.4 kernel doesn't hit the MMU/reset bug directly, I've done some additional testing to ensure we didn't introduce any weird regressions. These scenarios included: - default crash kernel config - nested VM crash kernel with multiple CPUs - nested VM crash kernel with default config - basic smoke testing of VM up/down through virsh - basic smoke testing of reboots from within the VM All of these behaved as expected and showed no issues. ** Tags removed: verification-needed-focal ** Tags added: verification-done-focal -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1948862 Title: KVM emulation failure when booting into VM crash kernel with multiple CPUs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1948862/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
