I just created a storage pool directory based in my Host KVM

# virsh pool-list --all

Name                 State      Autostart 
guest_images_dir     active     yes

And the info:

# virsh pool-info guest_images_dir

Name:           guest_images_dir
UUID:           720c6735-9ca0-e7c2-18cf-396c729a512e
State:          running
Persistent:     yes
Autostart:      yes
Capacity:       920.54 GB
Allocation:     23.02 GB
Available:      897.51 GB

Here is the XML

# cat /etc/libvirt/storage/autostart/guest_images_dir.xml 

<pool type='dir'>

But I can't see it on my guest Windows 2008. What else do I do?

A pool is a place where you are supposed to place images. You will not see it form the VM, because what the VM can see are images, as disks, not the grouping of the images in pools.

If you go into the pool, and create a volume there, and attach that volume to the VM, it will see a new attached disk, it will be able to format and use

So I can't share a host folder to multiples guest at the same time? Without using NFS, SMB, etc I mean. Because if I use SMB or NFS I only have speeds around ~10MB/s (ethernet speed) and I want to get the HDD's speed – blacksoul Jun 28 '12 at 23:12
you can, but you set up a shared volume for that. And if a lot of systems will be using it, you need a clustered FS – dyasny Jun 29 '12 at 3:11
Is there any website that explain that? I have been looking for it but I can't found anything to share a volume or "mount point" for HOST and multiples GUESTs at the same time – blacksoul Jun 29 '12 at 7:08
no, you can only share a virtual disk image between guests. That disk image is a volume in the libvirt storage pool. If you need to access this image from the host you have libguestfs/guestfish for that – dyasny Jun 29 '12 at 10:59
Is it sure and recommended? – blacksoul Jun 29 '12 at 11:50
