Subject: [ovirt-users] Can't understand Template Sub Version
Hi, All
I'm using oVirt Engine Version: 3.4.3-1.el6, but I can't
understand this function. I have 3 question:
1 How to change a vm to use other template sub version?
I don't want to build a new vm from new template version.
2 How to update a pool to use other template sub version?
I'm using non latest version, and shutdown all vm of this pool,
but I still can't change template version.
there is a gap, user cannot update the template version of already created vm or pool
there is an open RFE for that:
Bug 1140569 - [RFE] Provide UI ability to change "Template versioning" policy
for existing pools
regarding 1 - please note that template versions are only relevant for stateless vms, not
all vms,
since upgrading to new version means re-creating the vm disks, according to new version.
3 How to create a pool with disable stateless function?
In the property of template vm, I'm sure I don't enable
"stateless". But in the testing, I found all the vm are stateless vm.
How to disable it, or I'll lost all config and personal data.
Thank you very much!
vm pools are stateless by definition, it creates you pool of vms that users can "take
from the pool", use it to do whatever they like,
and once "returned" to the pool, all the user specific changes are gone, hence
stateless.
you can work with pools in 2 modes:
automatic - vm returned to the pool when user shut it down.
manual - admin need to manually return the vm to the pool, this way the state for the user
is saved also between shut-downs, until the admin action.
