Hello,

Youtube is working but not like the native experience (there are some
glitches in audio and video).
I see 50-70 Mbps net traffic between the spice-server (proxmox) and the
spice-client when youtube video is running, I consider this too high.
Normal traffic is around 1-2 Mbps and some times is reaching 10 Mbps.

To accomplish above with proxmox I believe that you need to use the linked
clones feature (I have not tested in production), see:
https://www.proxmox.com/en/news/press-releases/proxmox-ve-3-0-released
https://pve.proxmox.com/wiki/VM_Templates_and_Clones

Just tried a simple test:


‚Äč
-Create a template from an existing win7 image to use as the base image,
vmid 301
-Create a linked clone from the above for a user, vmid 302
-Create a full clone from vmid 301 to update the base image (e.g. perform
software updates), vmid 303
-Create a linked clone from the above to update the image to the user, vmid
303

As you can see below sizes of linked clones are very low (it always depends
to the size of changes applied) compared to the base image of 100G.
The time required to create the linked clones from the template is few secs.

./301:
total 82G
-r--r--r-- 1 root root 101G Sep 30 13:02 base-301-disk-1.qcow2
./302:
total 210M
-rw-r--r-- 1 root root 210M Sep 30 13:47 vm-302-disk-1.qcow2
./303:
total 81G
-r--r--r-- 1 root root 100G Sep 30 13:36 base-303-disk-1.raw
./304:
total 307M
-rw-r--r-- 1 root root 307M Sep 30 13:47 vm-304-disk-1.qcow2

Best Regards,
Dimitris
