Package: autopkgtest Version: 5.16 Severity: normal Tags: patch Dear Maintainer,
I found that autopkgtest-virt-qemu in bullseye doesn't boot my disk images. The version in buster was working fine. Using --show-boot I found that the VM doesn't boot at all: Booting from Hard Disk... Boot failed: could not read the boot disk The reason is that my disk images are raw images, not qcow2. I found that autopkgtest runs qemu-img to create an overlay file in qcow2 format, but it configures qemu with the base image format (format=raw) instead of the overlay format (format=qcow2). I converted an image to qcow2 format and then it worked fine. I'm attaching a patch to use format=qcow2 for the overlay image. Please let me know if you'd prefer a Salsa merge request instead.

Otherwise, use the base image format. --- lib/autopkgtest_qemu.py | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/lib/autopkgtest_qemu.py b/lib/autopkgtest_qemu.py index 6733ede..fc8225c 100644 --- a/lib/autopkgtest_qemu.py +++ b/lib/autopkgtest_qemu.py @@ -156,13 +156,14 @@ class QemuImage: if self.overlay is None: bits.append('file={}'.format(self.file)) + bits.append('format={}'.format(self.format)) else: bits.append('file={}'.format(self.overlay)) + bits.append('format=qcow2') bits.append('cache=unsafe') bits.append('if=virtio') bits.append('discard=unmap') - bits.append('format={}'.format(self.format)) if self.readonly: bits.append('readonly') -- 2.30.2
