2024-03-05debvm-run: add --transport optionHelmut Grohne
What was named bus earlier is called transport in qemu and we should name it the same way when exposing it.
2024-03-05debvm-run: refactor bus managementHelmut Grohne
Depending on the machine type, devices reside on different buses. For most vms, we use the pci bus, but m68k uses the virtio ("device") bus. Also if we were to use an x86 microvm, we'd also use virtio. This is common to all devices and we can abstract it into a $BUS.
2024-03-05debvm-run: skip rngdev for sparc64 via opt_skipHelmut Grohne
2024-01-09debvm-run: use -cpu max for kvmHelmut Grohne
When kvm works, passing "max" will get us "host" as before. When it does not, "host" doesn't work at all, but "max" will somewhat. Suggested-by: Michael Tokarev <mjt@tls.msk.ru>
2024-01-09disable highmem for 32bit arm by defaultHelmut Grohne
Since recent qemu, a non-lpae kernel cannot boot a highmem-enabled virtual machine. A typical failure is: pci-host-generic 4010000000.pcie: can't claim ECAM area [mem 0x10000000-0x1fffffff]: address conflict with pcie@10000000 [mem 0x10000000-0x3efeffff] Since the default kernel image is non-lpae, we disable highmem by default.

2024-01-07debvm-run.1: more details on disabling networkHelmut Grohne
Reported-by: Johannes Schauer Marin Rodrigues <josch@mister-muffin.de>
2023-09-24bin/debvm-waitssh: make --timeout=N workJohannes Schauer Marin Rodrigues
2023-07-04bin/debvm-run: commas in the image filename must be escapedJohannes Schauer Marin Rodrigues
2023-06-24bin/debvm-run: allow being run in environments without TERM setJohannes Schauer Marin Rodrigues
2023-06-22Merge run-skip into mainHelmut Grohne
2023-06-22debvm-run: restore behaviour of repeated --sshport flagsHelmut Grohne
When issuing multiple --sshport options, the last one should win. Fixes: a2db07766257 ("debvm-run: add a --netopt option to customize the -netdev")
2023-06-22Merge run-netopt into mainHelmut Grohne
2023-06-22Merge qemu-append into mainHelmut Grohne
2023-06-22debvm-run: expand the rootdev skipHelmut Grohne
2023-06-21debvm-run: add a --netopt option to customize the -netdevHelmut Grohne
2023-06-20debvm-run: add a --skip optionHelmut Grohne
As with debvm-create, this option allows skipping default configuration to let a user override things in their way. Link: https://bugs.debian.org/1036918
2023-06-20debvm-run: fix local emulation of set -exHelmut Grohne
Should be using stderr. Fixes: 7d0b160531d6 ("debvm-run: replace shell process with qemu process")
2023-06-19debvm-run: match on DEB_HOTS_ARCH_CPU rather than DEB_HOST_ARCHHelmut Grohne
This way we loose unnecessary detail such as libc, kernel and abi. For one thing this simplifies the arm* match. For another, this makes us stop think about arm64ilp32 or x32.
2023-06-19debvm-run: make shellcheck happyHelmut Grohne
Fixes: 1c98a5b3b36f ("bin/debvm-run: qemu (>> 1:8.0) provides symlinks for qemu-system-${debarch} as well as qemu-system-any")
2023-06-19bin/debvm-run: qemu (>> 1:8.0) provides symlinks for qemu-system-${debarch} ↵Johannes Schauer Marin Rodrigues
as well as qemu-system-any
2023-06-19debvm-run: avoid hard coding fds for kernel and initrdHelmut Grohne
qemu makes heavy use of fd passing, so we better avoid user-passed fds.
2023-06-19debvm-run: replace shell process with qemu processHelmut Grohne
We need the intermediate shell process to clean the temporary files with the kernel and the initrd - unless we delete them before running qemu. This method should help with killing a qemu e.g. using a timeout.
2023-06-09the argument to setterm is --resize, not -resizeHelmut Grohne
2023-06-07debvm-run: add an --append optionHelmut Grohne
Unlike qemu's -append, it has append semantics both to repeated use and to internal defaults.
2023-04-27debvm-create: recognize finit as an init systemHelmut Grohne
2023-03-30debvm-run: do not apply pauth-impdef=on to arm32Helmut Grohne
I really should have tested this part, but CI did. Fixes: 954ba600ffb7 ("debvm-run: massively speed up tcg emulation of arm cpus")
2023-03-29debvm-run: massively speed up tcg emulation of arm cpusHelmut Grohne
pauth emulation is very intensive on the CPU and thus there is a non-cryptographic alternative that provides a speedup of 3 to 4. https://qemu-project.gitlab.io/qemu/system/arm/cpu-features.html#tcg-vcpu-features Suggested-by: Arnd Bergmann <arnd@arndb.de> Reported-by: Emanuele Rocca <ema@debian.org> Tested-by: Emanuele Rocca <ema@debian.org> Closes: #1033643
2023-03-19debvm-waitssh: improve comment about character rangesHelmut Grohne
Reported-by: Jakub Wilk <jwilk@debian.org>
2023-03-11debvm-run: --graphical should not require an argumentHelmut Grohne
2023-03-06debvm-create: autodetect size of serial consolesHelmut Grohne
We now extend /etc/profile to invoke setterm -resize when detecting an interactive login on a serial console. This should fix 90% of wrongly sized serial consoles.
2023-03-06debvm-create: deprecate and hide the -a optionHelmut Grohne
At this point, we only forward -a to mmdebstrap. It's not actually that helpful to have this option on both levels, so just keep it on the mmdebstrap level.
2023-03-06support a mips64el kernel in a mipsel image via multiarchHelmut Grohne
Reported-by: Fabian Gruenbichler
2023-03-05debvm-create: extend examples in the manual pageHelmut Grohne
2023-03-05debvm-run: always use virtio input devices for graphical modeHelmut Grohne
These clearly benefit the amd64 case as well. Experience with the virtio gpu is not as clear cut as it may crash qemu.
2023-03-02debvm-run: be more explicit about graphics and cloud kernelsHelmut Grohne
Reported-by: Arnd Bergmann <arnd@arndb.de>
2023-03-02debvm-run: improve graphical experience on !x86Arnd Bergmann
2023-02-23debvm-create: also support --initsystem=busyboxHelmut Grohne
Reported-by: Johannes Schauer Marin Rodrigues <josch@debian.org>
2023-02-23debvm-create: also support --initsystem=runitHelmut Grohne
2023-02-23debvm-create: do not fsckHelmut Grohne
Asking for a fsck pass in fstab is not what we want. Requiring fsck makes sysvinit fail when fsck.ext4 is missing. Without that pass, it happily boots without e2fsprogs. Link: https://bugs.debian.org/1028267 Thanks: Thorsten Glaster <t.glaser@tarent.de>
2023-02-20debvm-create: add --initsystem optionHelmut Grohne
This option allows changing the init system. The notable addition is sysv.
2023-02-20debvm-create: avoid failing when we install no passwdHelmut Grohne
2023-02-05debvm-create: fix resizing of output imageHelmut Grohne
resize2fs -b will not actually perform a resize. Rather, it will truncate the file to the filesystem length, reversing the earlier truncate call. Thus we need second resize2fs call to change the size of the filesystem. Fixes: 09bcaa8fe901 ("debvm-create: make the ext4 look more like ext4")
2023-02-05debvm-create: add --skip=initsystemHelmut Grohne
Closes: #1030254
2023-02-05debvm-create: install systemd-sysv rather than initHelmut Grohne
We actually expect systemd in the network configuration. Be more honest about this.
2023-02-03debvm-create: update documentation for --skip=ext4Helmut Grohne
2023-02-02debvm-create: Output image in tar format if step "ext4" is skippedGioele Barabucci
Outputting the image in tar format breaks interoperability with `debvm-run`, but makes it easier to inspect, convert or perform additional modifications of the generated image.
2023-02-02debvm-run: deal with arbitrary disk labelsHelmut Grohne
Reported-by: Gioele Barabucci <gioele@svario.it> Closes: #1030255
2023-02-02debvm-create: make the ext4 look more like ext4Helmut Grohne
One notable difference remains. metadata_csum keeps missing as tune2fs insists on doing this interactively only. Reported-by: Gioele Barabucci <gioele@svario.it> Closes: #1030252
2023-01-26debvm-run: be a bit more verbose about detected architectureHelmut Grohne
