Hello Rod, or anyone else affected, Accepted qemu into eoan-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/qemu/1:4.0+dfsg- 0ubuntu9.2 in a few hours, and then in the -proposed repository. Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-eoan to verification-done-eoan. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-eoan. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping! N.B.

[Bug 1848556] Re: qemu-img check failing on remote image in Eoan
Since it seemed so easy, while bisecting I found that it hangs with v4.0.0 and v3.1.0 from git and even v3.0.0. Since the reported good version was 3.1 I began to wonder if I might have overlooked something. I wondered if it might be e.g. the apache version providing a different behavior on http. I was trying to access the same apache server with 4.0 and 3.1 and ran it against the download target: $ qemu-img check https://download.fedoraproject.org/pub/fedora/linux/releases/30/Cloud/x86_64/images/Fedora-Cloud-Base-30-1.2.x86_64.qcow2 3.1 ran into a segfault and 4.0 seems to hang on that. Maybe I should take a break and revisit that later, as people might have an idea already what this might be about. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1848556 Title: qemu-img check failing on remote image in Eoan Status in QEMU: Confirmed Status in qemu package in Ubuntu: New Bug description: The "qemu-img check" function is failing on remote (HTTP-hosted) images, beginning with Ubuntu 19.10 (qemu-utils version 1:4.0+dfsg- 0ubuntu9).

[Bug 1848556] Re: qemu-img check failing on remote image in Eoan
Quick checks: - does not depend on the exact image, e.g. https://cloud-images.ubuntu.com/eoan/current/eoan-server-cloudimg-amd64.img or https://download.fedoraproject.org/pub/fedora/linux/releases/30/Cloud/x86_64/images/Fedora-Cloud-Base-30-1.2.x86_64.qcow2 hang as well - the former qemu 3.1 based qemu-utils work fine Maybe that helps to identify a known patch that might already exist. Even it if doesn't the simple repro in comment #2 should still help. If there is no immediate idea out of the data we have let me know, this seems bisectable to me. ** Also affects: qemu (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1848556 Title: qemu-img check failing on remote image in Eoan Status in QEMU: Confirmed Status in qemu package in Ubuntu: New Bug description: The "qemu-img check" function is failing on remote (HTTP-hosted) images, beginning with Ubuntu 19.10 (qemu-utils version 1:4.0+dfsg- 0ubuntu9).

Hi Rod, I did try to recreate with the qemu version that you have. $ apt install apache2 qemu-system-x86 $ qemu-img create -f qcow2 /var/www/html/test.img 1G # local $ qemu-img check test.img No errors were found on the image. # remote $ qemu-img check http://localhost:80/test.img No errors were found on the image. Image end offset: 262144 Local check and remote check both work just fine. I recognized the image that you have there and then did: $ cd /var/www/html/ $ wget https://cloud-images.ubuntu.com/bionic/current/bionic-server-cloudimg-amd64.img # local $ qemu-img check bionic-server-cloudimg-amd64.img No errors were found on the image. 16651/36032 = 46.21% allocated, 98.92% fragmented, 98.49% compressed clusters Image end offset: 344195072 # remote $ qemu-img check http://localhost:80/bionic-server-cloudimg-amd64.img Therefore I can confirm the behavior you described. ** Changed in: qemu Status: New => Incomplete ** Changed in: qemu Status: Incomplete => Confirmed -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1848556 Title: qemu-img check failing on remote image in Eoan Status in QEMU: Confirmed Bug description: The "qemu-img check" function is failing on remote (HTTP-hosted) images, beginning with Ubuntu 19.10 (qemu-utils version 1:4.0+dfsg- 0ubuntu9).
