<bennabiy>
alkisg: When doing an install, what is the default going to be? NBD, NFS, AoE? (Ubuntu related systems)
21:09
for 5.5 and 6.0
21:09
<alkisg>
bennabiy: for ubuntu, NBD
21:09
<bennabiy>
ok
21:09
<alkisg>
for debian, NFS, for opensuse, AOE :)
21:09
<bennabiy>
ok :)
21:12
alkisg: what is the best solution for running a windows client within a thin client lab? So far I have tried both virtualbox and KVM, running on the server and connected from the thin client via remmina as rdp
21:12
<alkisg>
Fast/fat clients or slow/thin clients?
21:12
<bennabiy>
slow
21:13
thin clients have 2 gigs of ram, but beans for a proc
21:13
actually, I think beans are faster
21:13
<alkisg>
I think I'd still use them as fat clients... which processor?
21:13
<bennabiy>
atom 280
21:13
N280
21:13
I think
21:14
<alkisg>
http://www.cpubenchmark.net/cpu.php?cpu=Intel+Atom+N280+%40+1.66GHz
21:14
<bennabiy>
I am fine with the clients for most general needs.
21:14
yes
21:14
<alkisg>
Yeah that's one of the lowest ones
21:14
<bennabiy>
yup.. I think I see beans 3 entries higher
21:14
<alkisg>
Well, I'd use a master XP vbox VM
21:14
And snapshot it/boot it over LTSP on the clients on the fly, locally
21:15
With SCREEN_07=windows or similar
21:15
<bennabiy>
What is the best way to export the image?
21:15
<alkisg>
You can export the read only .vdi file with nbd or aoe, whatever you like
21:16
The snapshot would be in RAM or in NBD_SWAP
21:16
...or even in SSHFS, whatever you prefer
21:16
<bennabiy>
the client would need to write changes to the windows disk
21:16
and to a shared disk on the linux host
21:17
<alkisg>
Why write changes? It would be like using deep freeze
21:17
Only the sysadmin would be able to do changes that survive reboots
21:17
Of course the user home would be in SSHFS or NFS, sure

21:18
<bennabiy>
I am fine with the windows install itself not needing to be written to, but the user needs from windows to be able to save files, which can be accessed in windows on the next reboot, and from the linux host
21:18
He also uses the thin client on the linux side for email and such
21:18
<alkisg>
Right, that's what vbox shared folders are for
21:19
<bennabiy>
So it would just be an RDP session ?
21:19
<alkisg>
No, vbox running locally on the client
21:19
It's the fastest you can do. Or, vmware client.
21:20
But not kvm, it's not good for desktop sessions
21:20
<bennabiy>
oh. I get it now.
21:20
<alkisg>
It's very good for server sessions
21:20
<bennabiy>
I use kvm all the time for servers, but I thought I would try it for the desktop... bah.
21:22
We do not use ltsp-pnp, so I would need to install virtualbox to the client image, and then also the general vm info?
21:23
<alkisg>
What do you mean general vm info?
21:25
<bennabiy>
I mean the vbox info for the xpclient, or would that be part of the nbd export?
21:26
<alkisg>
Ideally that should be generated on the fly to match the client specs
21:27
<bennabiy>
what is the best way to do that?
21:27
<alkisg>
E.g. if the client has 4 cores, it should use 4 cores, if it has 2 GB RAM, it should use 1.5 RAM etc
21:27
...the best way is to write a "vbox" LTSP screen script :)

Meh overlayfs is broken currently in 14.04, it reports zero free space, while aufs works fine...
