Hello,
I noticed that a vm created from a "sealed" template is initially
mount
on one host with libguestfs, with a virt-sysprep process, before
getting
ready to be used.
This should be unuseful given that the template is already sealed. Is
there a reason to that?
Yes, we do this in order to produce different LVM IDs and machine IDs
for the provisioned VMs, see:
https://gerrit.ovirt.org/c/ovirt-engine/+/115009
okay, but, I modified the
/usr/lib/python3.6/site-packages/vdsm/virtsysprep.py file like following:
args = ['--hostname', 'localhost', ''--selinux-relabel',
'--update',
'--network']"
in order to update packages on template creation.
The template creation still works and the template is checked as sealed
and os is updated, but now the vm creation never ends up and I have to
manually kill the virt-sysprep process to stop the infinite process
creation.
I believed it was a good workaround to get updated templates, but I had
to rollback to default virt-sysprep args configuration, unless there is
trick do to so?
