   • ​cpu-checker 0.1-0ubuntu2

     Description: tools to help evaluate certain CPU (or BIOS) features

     There are some CPU features that are filtered or disabled by system BIOSes. This set of tools seeks to help identify when certain features are in this state, based on kernel values, CPU flags and other conditions. Supported feature tests are NX/XD and VMX/SVM.

Console Redirection

• ​Redirect Qemu Console to a file or the host terminal? - Stack Overflow
• ​qemuでシリアル接続 - linuxとかテストとか

• -nographicは-serial stdioに相当する模様
• -serial ptyとすると、char device redirected to /dev/pts/3のようにして接続すべき疑似端末が示されるので、minicomなどを用いて接続する
