Hi,
in a pool the vm is not stateless only?
I created a pool and I assigned users to it.
I applied your solution and it works fine.
I would like to tell you that after I upgrade the server, the firewall
is always abilitated though I've disabled.
After that I must disable the firewall.
Thank you a lot for your help.
VMs from a pool are stateless (return to base on shutdown) if:
- started from admin portal as stateless (via runonce)
- started from user portal (as-is) in an automatic pool
VMs from a pool are statefull if:
- started from admin portal
- the pool is manual - until the VM is "returned to pool".
admin not being stateless allows to do the following;
- create the pool
- start the VMs from the admin portal (say, to have them sysprep)
- shut them down, take a snapshot!
- now use them as statless with the snapshot
(Omer - was this use case checked with template versions - that all
snapshots are deleted? does it delete the entire VM?)
