1. " hash -- holds the md5 like encryption indicating a change "
I don't think "encryption" is relevant here.
right , replaced with
hash
2. VMOldInfoManager
how will we know/flag when we expect it can be deleted?
("Old" is relative. what if you will need to create another OldOld
class? maybe something more specific like 3_0, so you know you can
delete it when you no longer have 3_0 clusters supported?)
Done
3. "Addresses are kept in the database as a plain-text strings"
at some point we will want to expose this to users. maybe a better
representation would be in order (could be handled later as part of
upgrade process i guess).
will ne handled later (when needed)
4. video cards
you mention only spice - what happens to VNC monitors?
Handled already, look on HLD
for
'qxl' - spice device, 'cirrus' - vnc device
5. floppy/cd-rom
expect there will be more than one cd-rom (looks as the most probably
solution to user data injection afaiu)
sure, we assume that those can be multiple
6. virtio-serial
you mention it in the beginning, but not afterwards wrt
implementation
details. there may be multiple of these (qemu-ga, ovirt-guest-agent,
spice-vd-agent?)
I think those will be handled as (un-managed) vm-device abd by definition can have
multiple entries
