Description Fabian Deutsch 2012-01-29 20:48:25 UTC

Qemu got support for it's curl backend, but sadly it seems to be broken. UPstream can't confirm this, so it might be related to the fedora specific patches.

Can be tested using
$ qemu -cdrom http://mirror.de.leaseweb.net/fedora/linux//releases/16/Fedora/x86_64/os/images/boot.iso

This package has changed ownership in the Fedora Package Database.  Reassigning to the new owner of this component.

Rawhide bugs tend to linger, so moving to F17.

Comment 3 Cole Robinson 2013-05-23 20:49:11 UTC

Hmm. Rich, I know you've followed the upstream thread about this, and I saw you mention something about Fedora's curl being 'broken'. Can you elaborate on that? Will the upstream patch series fix things even with Fedora's curl ?

Fedora's curl simply doesn't work.  Upstream curl from git
works fine.

Try this test on Fedora 19 w/ qemu >= 1.4 and libguestfs 1.22.
You will need a remote disk image of some sort available over HTTP.

With Fedora curl:

$ export LIBGUESTFS_BACKEND=direct
$ guestfish -a http://192.168.0.249/scratch/winxp.img -i -v
[it just hangs when running qemu using 100% CPU]

With upstream curl compiled from git:

$ export LD_LIBRARY_PATH=~/d/curl/lib/.libs
$ export LIBGUESTFS_BACKEND=direct
$ guestfish -a http://192.168.0.249/scratch/winxp.img -i -v
[...]

Welcome to guestfish, the guest filesystem shell for
editing virtual machine filesystems and disk images.

Type: 'help' for help on commands
      'man' to read the manual
      'quit' to quit the shell

Operating system: Microsoft Windows XP
/dev/sda1 mounted on /

><fs> 

I don't know why this is.  We seem to patch curl heavily
in Fedora.

No.
