My team build environment has amd64 native architecture hardware. I ran a similar scenario on an AWS arm64 native machine (QEMU is not needed) and the command works fine in the container. +3. My team builds several Linux images daily - about a dozen amd64 and eight arm64. This is the only image that's causing us this problem. +4. I built trace-cmd but when I tried to start a trace it told me `No events enabled with kvm`. +5. I built qemu-8.1.0-rc3 and saw the same behavior but I don't think `/usr/libexec/qemu-binfmt/aarch64-binfmt-P` was replaced with a new version so I don't think the old version was used for my container. |
