a) That uploader is taking forever.
b) It makes access to /var/virtualization VERY slow on primary-master-node!
c) There's a limit to the file size of 1GB.

About a):
I'm not sure but it seems uploads with scp were faster.
Even worse, once the file is on the server, it takes ages to move it to /var/virtualization (about 10MB per second).
In VM-manager, it's been showing 99% and 9 seconds left for quite a while now, and I can very slowly watch the file grow in /var/virtualization/iso-choosable.

About b)
While the file grows in /var/virtualization/iso-choosable, any access to that share is VERY slow, see this:
foss-cloud-node-01 log # time ls -alh /var/virtualization/iso-choosable
total 976M
drwxrws--- 2 root vm-storage 103 28. Feb 19:55 .
drwxrws--- 9 root vm-storage 4.0K 28. Feb 18:49 ..
-rw-r--r-- 1 apache apache 422M 28. Feb 19:41 en_windows_7_professional_with_sp1_x64_dvd_u_676939.iso
-rw-r--r-- 1 apache vm-storage 555M 28. Feb 20:30 Fedora-18-i686-Live-XFCE.iso

user 0m0.000s
sys 0m0.007s
foss-cloud-node-01 log #

So it takes 8 seconds to read that folder?
Could this also slow down running VMs?

c) 1GB Limit
CWI confirmed that the maximum size for an upload is currently set to 1GB.
