Hi all
We're using RHEV 3.5.7 and have about 40 desktop VMs that are all clones
from a single original.
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
primary domain failed" error messages.
We use DHCP for all desktops however every VM is defined on the DHCP server
and unknown MACs are rejected.
I'd like to revisit desktop pools but I'd like to know if other are using
this and what their experiences have been.
Kind of thing I'd like to know is
- how is patching done
- what is the performance like
- what tuning if any is done on the desktops
- GPO vs LPO
Any comments?
Thanks

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 and thanks for the reply.
Not really what we're after. We want the stateless VMs but we want to be
able to work on the template (patch, install addtional software, etc) and
have those changes flow through to the existing VMs based on these
templates. In addition, when the VMs are refreshed based on the updated
template, we need the MAC addresses to persist (as we define all our leases
in DHCP).
Thanks
