Hi, all!
I'm trying virt-manager on Debian Wheezy and I noticed that it has
already defined a "default" pool. But if I run:
# /etc/init.d/libvirt-bin restart
I lose the definition of the pools. Actually, there are the definitions
of the pools; but these are not read after restarting libvirt.
ss01:/etc/libvirt/storage# ls -l
total 8
drwxr-xr-x 2 root root 4096 jun 1 09:36 autostart
-rw------- 1 root root 664 jun 1 13:46 default.xml
ss01:/etc/libvirt/storage/autostart# ls -l
total 0
lrwxrwxrwx 1 root root 32 may 24 07:24 default.xml ->
/etc/libvirt/storage/default.xml
After restart libvirt:
virsh # pool-list
Name State Autostart
-----------------------------------------
This is what I see in libvirtd.log:

It seems the problem is given by: "XML error: malformed owner element".
Owner and group should uid and gid of the images directory.
ss01:~# ls -ld /var/lib/libvirt/images
drwx--x--x 2 root root 4096 may 27 11:03 /var/lib/libvirt/images
So I adapted the permissions to this directory:
<permissions>
<mode>0700</mode>
<owner>0</owner>
<group>0</group>
</permissions>
After restarting libvirt, the pool was recognized:
virsh # pool-list
Name State Autostart
-----------------------------------------
default active yes
Then I went back to create another pool:
virsh # pool-define-as ISO dir - - - - "/space/isos"
Pool ISO defined
virsh # pool-start ISO
Pool ISO started
virsh # pool-autostart ISO
Pool ISO marked as autostarted
virsh # pool-list --all
Name State Autostart
-----------------------------------------
default active yes
ISO active yes
Files are created:
ss01:/etc/libvirt/storage# ll
total 12
drwxr-xr-x 2 root root 4096 jun 2 15:49 autostart
-rw------- 1 root root 646 jun 2 15:05 default.xml
-rw------- 1 root root 644 jun 2 15:48 ISO.xml
ss01:/etc/libvirt/storage/autostart# ll

lrwxrwxrwx 1 root root 32 may 24 07:24 default.xml ->
/etc/libvirt/storage/default.xml
lrwxrwxrwx 1 root root 28 jun 2 15:49 ISO.xml -> /etc/libvirt/storage/ISO.xml
But it seems that the permissions are equally incorrect:
ss01:/etc/libvirt/storage# cat ISO.xml

This have to do with a bug when using libvirt on a 32-bit operating system?
