Package: simple-cdd Version: 0.6.7 Severity: normal
While using simple-cdd this weekend, I discovered a few things about the disk image used with qemu-based testing. The simple-cdd.conf.detailed file documents two settings for the disk image: hd_img and hd_size. These two settings are ignored by simple-cdd. The default disk is a qcow image with the name qemu-test.hd.img stored in the project root. There are four improvements I'd like to make here: * Change this to a qcow2 format to open up additional capabilities of the qcow2 format. This may also improve performance (untested). * Change the name to qemu-test.hd.qcow2 to make it more obvious to a developer what the file is and its format. * Move the file to the $simple_cdd_tmp folder, in a qemu subfolder, to better organize it with the rest fo the temporary build files. * Change the script to use qemu's -drive option to improve the speed of the disk emulation. With the existing -hda setting, even simple tests take hours to complete, whereas -drive with some extra options reduces it to a couple minutes. The PR at https://salsa.debian.org/debian/simple-cdd/-/merge_requests/2 addresses all of the above issues: * Honor hd_img and hd_size, if they're set. * Change default hd_img format and extension to qcow2. * Use -drive instead of -hda for more options and performance. * If hd_img isn't an absolute path, store it in tmp/qemu. -- System Information: Debian Release: 10.4 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.5.0-0.bpo.2-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages simple-cdd depends on: ii dctrl-tools 2.24-3 ii debian-cd 3.1.25 ii lsb-release 10.2019051400 ii python3 3.7.3-1 ii python3-simple-cdd 0.6.7 ii reprepro 5.3.0-1 ii rsync 3.1.3-6 ii wget 1.20.1-1.1 Versions of packages simple-cdd recommends: ii dose-distcheck 5.0.1-12 Versions of packages simple-cdd suggests: ii qemu-kvm 1:3.1+dfsg-8+deb10u5 -- no debconf information
