[Bug 1848556] Re: qemu-img check failing on remote image in Eoan

[Max Reitz]

Hi Rod,

You don’t need to add anything, but maybe there’s some library missing.
--enable-curl should force support and then tell you whether there’s
something missing.

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). With previous versions, through Ubuntu 19.04/qemu-utils
  version 1:3.1+dfsg-2ubuntu3.5, the following worked:

  $ /usr/bin/qemu-img check  
http://10.193.37.117/cloud/eoan-server-cloudimg-amd64.img
  No errors were found on the image.
  19778/36032 = 54.89% allocated, 90.34% fragmented, 89.90% compressed clusters
  Image end offset: 514064384

  The 10.193.37.117 server holds an Apache server that hosts the cloud
  images on a LAN. Beginning with Ubuntu 19.10/qemu-utils 1:4.0+dfsg-
  0ubuntu9, the same command never returns. (I've left it for up to an
  hour with no change.) I'm able to wget the image from the same server
  and installation on which qemu-img check fails. I've tried several
  .img files on the server, ranging from Bionic to Eoan, with the same
  results with all of them.
