> @Nobuto - has your system any of the above kernel parameters set manually?
No, we don't have any flags in kernel parameters related to tsx or similar. FWIW, I haven't tested any older kernel to check if those flags are available. But we are using Intel(R) Xeon(R) Gold 6150 CPU @ 2.70GHz. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1853200 Title: cpu features hle and rtm disabled for security are present in /usr/share/libvirt/cpu_map.xml To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1853200/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
