Questions before switching to Proxmox with kvm

[Maksimus]

We are planning to switch from kvm to proxmox. In connection with this, many small questions arose (for 3 months of tests, about 100 questions). We found the answer to something ourselves, but still we want to get an answer from the developers for the main and important ones.
1. Is it possible to change the standard port from 8006 to any other?
2. Is there any system of protection against brute force passwords for web access?
3. Is it possible to add lower versions, for example 7.0, to a cluster based on PVE 7.2? Future versions 7.* ?
4. Is it possible to create a backup of each disk of one VM with a different schedule? For example, drive C is stored for 14 days, and drive D is stored for 30 days?
5. Is it possible to change vm id after vm is already installed?
6. Can I set up a schedule to restore from a backup? For example, once a day, restore the last backup.
7. How to move a vm backup between datastores of the same PBS?
8. The ability to log into the web from any node under a single account for the entire cluster?

hi,

1. Is it possible to change the standard port from 8006 to any other?

you can set up an nginx proxy [0]

2. Is there any system of protection against brute force passwords for web access?

fail2ban is supported [1], we also have two factor authentication [2]

3. Is it possible to add lower versions, for example 7.0, to a cluster based on PVE 7.2? Future versions 7.* ?

yes, as long as you don't mix different major versions (e.g. 6.x with 7.0 and so on) you should be fine, though it's still recommended to have all the nodes updated to the same package levels to avoid inconsistencies.

4. Is it possible to create a backup of each disk of one VM with a different schedule? For example, drive C is stored for 14 days, and drive D is stored for 30 days?

as far as i know no, but you can make a feature request on our bugtracker [3]

5. Is it possible to change vm id after vm is already installed?

you can clone the VM to another ID and delete the old one.
otherwise this is not so trivial because you need to rename the disks from the old names (they include the VMID).

6. Can I set up a schedule to restore from a backup? For example, once a day, restore the last backup.

yes

7. How to move a vm backup between datastores of the same PBS?

afaik no support for this on the GUI yet

8. The ability to log into the web from any node under a single account for the entire cluster?

this already works by default (except if your root@pam password is different for each node, but then again you can still login as root on any node and be able to manage the other ones from the GUI)

hopefully this clears some things for you!

7. No support in the GUI is not scary, is this possible through console commands?
8. I want a pve user for the entire cluster.

8. I want a pve user for the entire cluster.

that should work too, root@pam was an example.
with a user in PVE realm you'll also have the same password on different nodes

7. No support in the GUI is not scary, is this possible through console commands?

you can actually add a remote to your server (pointing to localhost) and sync it like that [0]. with our latest "group filter" feature you can single out backups as well.

using the CLI you could copy over the files and (hidden) directories inside the datastore but you'd need to make sure to keep the file permissions.

otherwise i'm not sure if you can move a single backup to another store, since the chunks are deduplicated between different backups as well.

6. Tell me where you can read more about this function.

automatic restore should be doable with a cron job and our qmrestore utility [0]

There are 2 nodes on each with 2 physical disks, when adding them to the storage, on the second node it does not allow creating a disk with the same name as on the first node (2storage disk2 name). But at the same time, if the VM is located on different disks on the first node, then during migration we get an error that there is no storage on node 2 with the name disk2.
Tell me how to create storages with the same names or how to migrate a VM hosted on 2 different storages to 2 nodes.
