Hi Colin,=20
I normally use desktop pools for virtual machines, which are the same, and =
single desktops for individual vms.=20
So mostly office vms are from a pool and admin vms aren't.=20
For patching you can either use some tools like Microsoft WSUS or for Linux=
vms Katello/Satellite/... or if you're using desktop pools it's also possi=
ble to patch the master image, create a new template with a new version and=
shut down all you vms. Afterwards they should boot with the new version if=
you did configure to always use the lastest version.=20
Performance of the virtual desktops depends on some things:=20
- protocol (Spice is really great in our tests) - also make sure you instal=
l all VirtIO drivers in your vms=20
- bandwith - this is no problem in the LAN, but for WAN setups this could b=
e an issue. Watching full HD videos in your vms can require 40mbit/s...=20
- thin clients - they need good graphics cards and at least 2gb ram and 2 c=
pu cores, better 4...=20
Most of my customers use GPOs for their virtual desktops, as it's easier to=
configure group policies then updating the master template too often...=20
I hope this helps...=20

Hi all=20
We're using RHEV 3.5.7 and have about 40 desktop VMs that are all clones fr=
om a single original.=20
In the very beginning we used desktop pools but this was torn down when we =
started getting "The trust relationship between this workstation and the pr=
imary domain failed" error messages.=20
We use DHCP for all desktops however every VM is defined on the DHCP server=
and unknown MACs are rejected.=20
I'd like to revisit desktop pools but I'd like to know if other are using t=
his and what their experiences have been.=20
Kind of thing I'd like to know is=20
- how is patching done=20
- what is the performance like=20
- what tuning if any is done on the desktops=20
- GPO vs LPO=20
Any comments?=20
Thanks=20
CC=20
