Comment 1 Alexander Todorov 2013-10-08 03:55:19 EDT
Creating the directory manually works around this issue so far.
Comment 2 Dario Faggioli 2013-10-08 06:21:05 EDT
And I think I'm just ading that I see this when trying to run `virt-install' from console to.

I just ssh-ed to my host and did the following:

# virt-install --paravirt --name f20_64 --ram 2048 --vcpus 4 -f /dev/fedora_odyn/f20_64 --network bridge=virbr0 --location http://dl.fedoraproject.org/pub/alt/stage/20-Beta-TC1/Fedora/x86_64/os/ --graphics none

And that's what I see:

[Errno 2] No such file or directory: '/root/.cache/virt-manager'

Traceback (most recent call last):
  File "/usr/share/virt-manager/virt-install", line 1073, in <module>
  File "/usr/share/virt-manager/virt-install", line 1036, in main
    cli.setupLogging("virt-install", options.debug, options.quiet)
  File "/usr/share/virt-manager/virtinst/cli.py", line 158, in setupLogging
    os.mkdir(vi_dir, 0751)
OSError: [Errno 2] No such file or directory: '/root/.cache/virt-manager'
Comment 3 Dario Faggioli 2013-10-08 06:21:52 EDT
Oh, and I also confirm that `mkdir -p /root/.cache/virt-manager' does the trick here too.

Seeing this on rawhide as well, virt-manager-0.10.0-4.git79196cdf.fc21.noarch
Comment 6 Giuseppe Scrivano 2013-10-31 13:47:41 EDT
XDG Base Directory Specification (Version 0.7) clearly states that if $XDG_CACHE_HOME is not defined, then a default equal to $HOME/.cache should be used to store user-specific data files.

I think virt-manager should create that directory if it doesn't already exist, in the same way as "mkdir -p $HOME/.cache/virt-manager" does.
Comment 7 Giuseppe Scrivano 2013-11-05 12:35:26 EST
patch accepted upstream:

commit 5798c5b9b42732caf98876a6a708379190dd9c6b
Author: Giuseppe Scrivano <gscrivan@redhat.com>
Date:   Fri Nov 1 13:26:24 2013 +0100

    virt-manager: prefer os.makedirs to os.mkdir when creating cache dir
    Ensure the parent directories exist when attempting to create the
    cache directory.

Comment 8 Cole Robinson 2013-11-05 13:18:38 EST
Since this can cause the app to fail to start if running as root, let's keep this open so users can track when a fixed update hits F20
